General Safety Information The information that follows, together with local site regulations, should be studied by personnel concerned with the operation or maintenance of the equipment, to ensure awareness of potential hazards. Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting damaged cables or antennas. Avoid standing in front of high gain antennas (such as a dish) and never look into the open end of a waveguide or cable where strong RF power may be present. Users are strongly recommended to return any equipment that requires RF servicing to Silvus Technologies. CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions should be employed to prevent accidental damage.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 10 1.1 Health & Safety Exposure to Non-Ionizing (RF) Radiation/Safe Working Distances The safe working distance from a transmitting antenna may be calculated from the relationship: D =  In which D = safe working distance (meters) PT = transmitter or combiner power output (watts) GR = antenna gain ratio = anti log (gain dBi ÷10) w = power density (watts/square meter) The RF power density value is determined by reference to safety guidelines for exposure of the human body to non-ionizing radiation. It is important to note that the guidelines adopted differ throughout the world and are from time-to-time re-issued with revised guidelines. For Silvus use, a maximum power density limit of 1w/m² is to be applied when calculating minimum safe working distances. Important Note: It must be remembered that any transmitting equipment radiating power at frequencies of 100 KHz and higher, has the potential to produce thermal and a-thermal effects upon the human body. To be safe: a) Operators should not stand or walk in front of any high gain antenna such as dish antennas, nor should they allow anyone else to do so. b) Operators should not operate any RF transmitter or power amplifier with any of its covers removed, nor should they allow anyone else to do so.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 12  If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment and/or equipment performance may be impaired.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 13 1.2 Maximum RF Power Density Limits The RF Radiation Power Density limit figure recommended by Silvus is based upon guideline levels published in: a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic Fields (up to 300 GHz) published in 1998 by the Secretariat of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled" environments. An uncontrolled environment is defined as one in which the person subjected to the RF radiation may be unaware of and has no control over the radiation energy received. The uncontrolled environment conditions can arise, even in the best regulated operations and for this reason the limits defined for the uncontrolled environment have been assumed for the RF Central recommended limit. Documents a) and b) also show the RF power density guidelines to be frequency dependent. Different power density / frequency characteristics are presented in the two documents. To avoid complexity and to avoid areas of uncertainty, Silvus recommends the use of a single power density limit across the frequency range 100 kHz to 300 GHz. The 1w/m² power density limit we recommend satisfies the most stringent of the guidelines published to date.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 14 2. Introduction The StreamCaster family of MIMO radios was designed with operator ease of use in mind. Each radio is capable of operating in a multitude of configurations that are accessed via simple web pages within the radio. Settings such as transmit power, frequency, channel bandwidth, link adaptation and range control can be accessed by simply using a web browser to log into any radio within the network. This quick start user guide contains all essential information for the user to configure the StreamCaster radio and to also run an iperf network test. 3. StreamCaster Network Each StreamCaster MIMO radio has a fixed static IP address in the 172.20.xx.yy network. The radio operates as a network switch; the user equipment does not need to be on the same subnet as the radio during operation. It is possible to setup a secondary IP address on the radio if the user finds this feature convenient. Setting up a secondary IP address is useful if the user wishes to access the radio’s web interface in their network.

Users can type “ping <IPaddress>” in order to determine whether the radio is fully booted. A web configuration will then be available by typing the radio IP address in a web browser. Please ensure that your laptop is on the same subnet as the radio (172.20.xx.xx by default). Users will be directed to the Basic Configuration page. (See Figure 23)

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 56 5.1.1 Basic Configuration Figure 23 Basic Configuration Page This page is used to set basic configurations. A brief description of each parameter is given below.  Frequency: This defines the frequency of the signal. There is a drop-down menu for frequency selection. The frequency choices will vary depending on the StreamCaster model(s) you are using. Please see Section 8 for “Custom Frequency Plan” access and installation instructions.  Bandwidth: This defines the RF bandwidth of the signal.  Network ID: Network ID allows for clusters of radios to operate in the same channel, but remain independent. A radio with a given Network ID will only communicate with other radios with the same Network ID.  Link Distance: Set to an approximate maximum distance between any two nodes in meters, e.g., 5000 for 5km (default). It is important to set the link distance to allow enough time for packets to propagate over the air. Failing to set the link distance to an approximate

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 57 maximum distance can result in over the air collisions and a degradation of performance. It is recommended to set the link distance 10-15% greater than the actual maximum distance.  Total Transmit Power: This defines the total power of the signal (power is divided equally between the radio antenna ports). There is also an option to ‘Enable Max Power’ which will allow the radio to push to the highest TX power it can support. This will be slightly different on each radio.  Wired Backbone Gateway: This setting pertains to wired backbone functionality (See Section 7: Wired Backbone). For normal operation, set Wired Backbone Gateway to ‘Auto’. If multiple radios will be connected to a wired backbone, all radios on the backbone should be set to ‘Auto’.  Routing Beacons on Ethernet Port: For radios to be able to communicate and transfer data over a wired link, routing information needs to be sent over the wireline. These packets are broadcast packets that are sent even if there is only one radio on the network. If wired backbone is not being utilized, the user can disable these routing beacons to prevent loading their local network with these routing packets.  Apply: Apply the new values. Values will change back to the default setting after reboot.  Save and Apply: Apply the new values and set the new values as the default.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 58 5.1.2 Advanced Configuration Figure 24 Advanced Configuration Page This page is used to set the advanced settings. A brief description of each parameter is given below. MAC Settings:  Routing Beacon Period: Controls how often routing beacons are sent to other radios. A lower Routing Beacon Period results in faster reaction to topology changes. A lower Routing Beacon Period also adds more overhead to the network which scales with the number of nodes in the network. For larger networks, a larger Routing Beacon Period is recommended. Default value is 100ms.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 59  Routing Beacon MCS: Select the MCS that routing beacons are sent at. Higher MCS values require less network overhead and may be beneficial for larger networks. The drawback is that the link will break when the Routing Beacon MCS can no longer be supported.  Fragmentation Threshold: Allows user to determine the minimum over-the-air packet size in bytes. Smaller packet size can improve performance in high mobility while a larger packet size will allow for more throughput. (1600 bytes default).  Maximum Ground Speed: This setting improves performance in high mobility scenarios where the wireless channel may change rapidly. Setting this value to an unnecessarily high value may have an impact as high as 25 percent on overall achievable throughput.  Burst Time: The burst time determines the maximum amount of time each node is allowed to transmit at once. A larger burst time will provide higher throughput at the cost of higher latency. On the other hand, a smaller burst time will provide less latency at the cost of less throughput. The throughput values shown in Table 18 and Table 20 assume the minimum burst time.  RTS Retries: A node wishing to send data initiates the process by sending a request to send message (RTS). The destination node replies with a clear to send (CTS) message. Any other node that receives the RTS or CTS message will refrain from sending data for a given time. In larger networks, there is a higher probability of collisions occurring when an RTS is sent out. This field defines the number of retries before a packet is dropped. A lower value will result in faster handoffs in mobile situations.  Number of Retransmissions: Allows the user to define the number of times a lost packet is retransmitted before being dropped. Default value is 20.  MCS: Choose the modulation and coding scheme (MCS). If this is set as AUTO, the radio will dynamically cycle between a subset of the modes depending on the quality of the link. This is the recommended setting for most users and will provide the maximum data rate that the link can support. The EXTENDED AUTO mode includes 64QAM rate modes on top of those included

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 60 in the AUTO mode. Table 18 and Table 20 below show the estimated UDP data rate and sensitivity for each MCS. This table assumes a 20MHz bandwidth, 1000 meter link distance and 1600 byte fragmentation threshold.  Transmit Channels: Allows user to Enable or Disable each channel on the radio for TX.  Receive Channels: Allows user to Enable or Disable each channel on the radio for RX.  Variable GI Mode: This feature can be used to improve performance in environments where long delay spread is present and causing Intersymbol interference (https://en.wikipedia.org/wiki/Intersymbol_interference). This setting allows the radio to vary its Guard Interval (https://en.wikipedia.org/wiki/Guard_interval) to allow for longer delay spread. When set to ‘Extended Auto – GI’, the radio will choose between the regular GI, and the user specified longer GI (Cyclic Prefix Length in the next setting) depending on channel conditions.  Cyclic Prefix Length: When Variable GI is set to ‘Variable’, the user must set the Cyclic Prefix Length. This setting determines the guard interval for the ‘Extended GI’ mode.  Beamforming (SC4200/SC4400 Only): Enable or disable TX Beamforming (Up to 2X increase in range when enabled)  Radio Mode: Switch between Network mode and PHY Diagnostics. If the value equals 0, it is in Network mode; if the value equals 1, it is in PHY Diagnostics. PHY Diagnostics mode is only relevant for users who wish to run diagnostic tests on the radio.  Apply: Applies the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 65 Figure 25 LAN/WIFI Configuration Page Network Settings:  Virtual IP: Enable or Disable the Secondary IP address for the radio.  Virtual IP Address: Set the secondary IP address for the radio. The user may set this to be on the user’s IP network, e.g., 192.168.2.10. Once this secondary IP address is set, the user may access the radio web page using either the native IP address or the secondary IP address. Please note that the secondary IP address should NOT be on the 172.20.xx.xx subnet.  Virtual Netmask: Netmask for the Secondary IP address, e.g. 255.255.255.0.  Gateway: Gateway for local network to allow radio to connect to the internet  VPN: For WAN wired backbone scenarios where radios from two different sites are connected via the internet, a public N2N server is needed to route the data. Here is an example of how to setup an N2N server on a server hosted by Amazon AWS running Ubuntu 12.04: Compile: git clone https://github.com/lukablurr/n2n_v2_fork ### downloads the code cd n2n_v2_fork export N2N_OPTION_AES=no

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 66 make clean make Execute: ./supernode -l 9000 -v Server will be running on port 9000.  VPN Server IP: IP Address of N2N VPN Server  VPN Server Port: Port that the N2N VPN server is configured to listen on. VLAN Settings (License Enabled Feature): VLANs allow users to segregate the Ethernet layer by assigning one or more VLAN IDs to the ports of a VLAN switch. Ethernet packets are only allowed to travel between ports that belong to the same VLAN. To allow concatenating multiple VLAN switches and/or a single physical interface residing on multiple VLANs, a VLAN ID can be inserted to the Ethernet packet header to indicate which VLAN the packet belongs to. This is called VLAN Tagging. A packet that contains a VLAN ID is called a tagged packet. A port on a VLAN switch typically operates in either access mode or trunk mode.  VLAN Mode: Specify ‘Access’ or ‘Trunk’ mode for the radio per the 802.1Q standard.  Default (Native/PVID) VLAN: This is the VLAN associated with untagged packets entering the radio. The virtual IP of the radio is available on this VLAN.  Management VLAN: This is the VLAN used for radio management (e.g. routing and network management). All radios on the network should have the same management VLAN. The 172.20.xx.yy IP of the radio is available only on this VLAN.  Trunk VLAN(s): This setting enables the trunking of VLANs when the radio is connected to an 802.1Q switch. If left empty, only the native and management VLAN traffic will be

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 67 allowed. User may enter a comma separated list of VLANS, e.g. 4,5,6 or an arry of VLANs in the format of a:b:c where a and c are start and end, and b is step size, e.g. 4:1:7 translates to 4,5,6,7. Any combination of the above is allowed. WiFi Settings (License Enabled Feature – SC3822 Only): Note: Use of this feature requires a Silvus USB-WiFi adapter. The WiFi settings will only display if the USB WiFi license is loaded, and the WiFi dongle is attached to the radio’s USB port before it is powered on.  Wifi Mode: Choose between AP, Client or Disabled. AP mode turns the WiFi dongle into a wireless AP. This mode is useful for connecting phones, tablets, laptops, etc. to the radio in order to pull up the web interface and access other devices in the mesh network. Client mode allows the radio to connect to another wireless AP. This mode is useful for connecting to wireless cameras and other devices which generate their own ‘hotspot’. Once set to client mode, a list of detected wireless networks will be displayed with an option to connect.  Mode: When set to AP, the wireless can be configured to be in Bridge Mode or NAT mode. In Bridge mode, the wireless interface is bridged with the Ethernet interface and the rest of the mesh. This is the simplest mode as all data is transparent and at layer 2. NAT mode puts the WiFi wireless traffic on a LAN, and the rest of the Silvus mesh network on a WAN. In effect, this means that a device connected wirelessly via the NAT AP will be able to find any device in the larger mesh network, but not vice versa. NAT mode is recommended for more advanced users who wish to be able to segregate data.  SSID: Define the SSID for the wireless network. Must be between 1-31 characters. User also has the option to prevent the AP from broadcasting it’s SSID by checking the ‘Hide’ box.  Security Mode: Determines whether the AP requires a password to connect.  Password: If ‘Security Mode’ is set to ‘Secure’, a password between 8 and 63 characters must be set.  Wifi Channel: The Silvus USB-Wifi adapter supports 20 different Wifi channels in both the 2.4GHz and 5GHz frequency ranges. It is recommended to set the Wifi channel to a frequency that has maximum separation from the mesh network frequency. (i.e. if mesh network is operating at 2.4GHz, it is recommended to set the Wifi frequency somewhere in the 5GHz range). Note that not all user devices support 5GHz Wifi.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 68  Wifi Standard: Specify 802.11b or g wifi standard. Some legacy devices may not be able to connect to an 802.11g network.  DHCP: When enabled, the USB-Wifi adapter will assign IP addresses to connected devices. Note that when the AP is set to ‘Bridge’ mode, the DHCP will be delivered to the entire mesh. Users should be careful to make sure there is only one DHCP server connected into the mesh network to avoid any conflicts. When DHCP is enabled, the DHCP parameters must be set.  Wifi TX Power: This slider can be used to control the Wifi TX power from 0dBm (1mW) up to 17dBm (50mW).  Wifi Status: Provides status information of the wifi adapter. A list of connected clients will also be shown here.  Port Forwarding (NAT Mode Only): When in NAT mode, devices on the larger mesh will not be able to locate devices connected to the wireless adapter. This can be overcome by mapping port forwarding for specific data streams.  Apply: Applies the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 69 5.1.4 Multicast Figure 26 Multicast Configuration Page  IGMP Snooping: Enable or Disable IGMP Snooping for Multicast traffic  Mesh: This option controls default behavior for local and mesh multicast traffic that has no IGMP snooping entries. If set to ‘Block’, all unregistered multicast traffic will be block. If set to ‘Send to All’, all unregistered multicast traffic will be sent to all radios.  Custom Pruning/Augmenting: Enable or Disable the Multicast group. The format for the field is Multicast_ip_address, receiver_id1, … receiver_idn If IGMP snooping is disabled, multicast traffic will only be forwarded to the radios in this list. If enabled, multicast traffic will only be forwarded to radios in this list that have client devices requesting this traffic. Traffic may be forced to go to a radio by adding the node with postfix “+”. Traffic may be prevented from reaching a radio by adding postfix “-”. (e.g. 224.50.50.50 1234, 1235-, 1236+) If receiver_id is -1, it will stop multicast traffic for this group. Multicast Pruning Examples: Data for multicast group 224.50.50.51 will be received only by radios with node-ids 1131 and 1261: 224.50.50.51, 1131, 1261

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 70 Data for multicast group 224.50.50.51 will be discarded at the transmitter and not put on the air: 224.50.50.51, -1 5.1.5 Quality of Service (QoS) #QoS

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 71 Figure 27 Quality of Service (QoS) Configuration Page Quality of Service Port Classification: The Quality of Service configuration page allows the user to make a distinction between low and high priority traffic transmitted through each radio. High priority traffic will always jump to the front of the queue and bypass any awaiting low priority traffic. In instances where the link cannot support the amount of data trying to be transmitted, low priority traffic may be completely shelved in order to ensure that the high priority traffic gets through. To specify Low/High priority traffic, the user needs to simply input the port number that the traffic will be arriving on. Multiple ports of the same priority can be separated by a comma (i.e. 5001, 6001, 6002). Alternatively, the user can specify a range of ports using a dash (i.e. 5001-5006). Any combination of commas and dashes will work as well (i.e. 5001, 6001-6007, 8000). Any field can be cleared by removing the text and clicking ‘Apply’ or ‘Save and Apply’. If unspecified, traffic is treated as Low Priority. Quality of Service Contention Window Control: The Quality of Service Contention Window Control tunes the aggressiveness of CSMA backoffs when collisions occur. The MAC takes random backoffs in the range [0, 2^cw_min]. Every time there is a collision/noise it will increase this cw_min by 1, until it is capped by cw_max.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 72 E.g. 4,10 translates to random backoffs in the range [0,16] in the beginning for a packet. If the first try results in a collision, it will pick another backoff in the range [0,32], then [0,64], until [0,1024]. After successful transmission, backoff is reset to [0,16]. The default is 4,10 for low priority, and 3,6 for high priority. For larger networks, it is recommended to increase the Low Priority minimum to reduce the chance of collisions occurring. End-to-End Automatic Repeat request (Beta Feature – License Enabled) The End-to-End ARQ feature provides packet re-ordering capability to the radio. This feature is useful in applications that are sensitive to out of order packets (i.e. video applications where the decoder does not have the ability to re-order packets). To enable packet reordering, specify the port number of the subject data in the same format as the QoS ports on the source and destination radio. The settings should match on both radios and do not need to be set on any relays. Retransmissions Disabled – Only packet re-ordering with no end-to-end retransmissions if packets are lost. The receiver timeout is the length of time the receiver waits for out-of-order packets before giving up and delivering the data it has in its buffer. This is similar in concept to the jitter buffer in common video decoders (e.g. VLC). The worst case end-to-end delay will be incremented by the receiver timeout value. Retransmissions Enabled – Packet re-ordering and end-to-end retransmissions enabled in case of packet loss. The retransmission timeout is the time the transmitter will wait before re-sending a lost packet. The worst case end-to-end delay will be incremented by the retransmission timeout value. Determining Timeout Value – Both receiver timeout and retransmission timeout should be set to roughly 3 times the end-to-end latency. The end-to-end latency can be found by disabling e2e and doing a ping between the transmitter and receiver.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 73 QoS Scheduler (Beta Feature – License Enabled) The Quality of Service (QoS) Scheduler feature provides a Hierarchical Token Bucket (HTB) scheduler. The scheduler prioritizes traffic based on the packets DSCP value. There are 12 queues in the scheduler; each with an assignable minimum bandwidth guarantee. First, the minimum guarantees are fulfilled for all queues waiting to transmit traffic out. If there is bandwidth remaining, it becomes available to highest priority traffic (lower number means higher priority) and it will take as much bandwidth as it needs to transmit out its data. Next, the remaining bandwidth will become available to the next lowest priority queue and so on. Traffic flows which map to the same priority will fairly share the available bandwidth using the Fair Queuing with Control Delay (FQ_CoDeL) scheduling algorithm. The feature is applicable to IPv4 and IPv6 untagged and tagged packets. Fragmented packets are not supported. Detailed below is the DSCP to queue/priority mapping. Queue Priority DSCP TOS DSCP Name 1 0 0x30 0xC0 CS6 2 1 0x2E 0xB8 EF 3 2 0x28 0xA0 CS5 4 3 0x26 0x98 AF43 0x24 0x90 AF42 0x22 0x88 AF41 5 3 0x20 0x80 CS4 6 4 0x1E 0x78 AF33 0x1C 0x70 AF32 0x1A 0x68 AF31 7 4 0x18 0x60 CS3 8 5 0x16 0x58 AF23 0x14 0x50 AF23

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 75 5.1.6 Serial/USB Setup Figure 28 Serial/USB Setup Configuration Page Serial Port Setup: Each StreamCaster is equipped with one user configurable serial port. A special power cable and null modem cable are required for access to the radio’s serial port. A brief description of each parameter is given below.  Serial Port Mode: The user can select one of four available modes for the serial port: GPS, RS232, Debug, and Disabled. o GPS: In GPS mode, an external serial GPS module can be connected to and powered from the serial port of the radio. A gpsd service daemon running on the node will make the GPS information available to any user on the network from TCP/IP port 2947. For more information on gpsd please see: http://catb.org/gpsd/ In addition, GPS information can be pushed to the radio via the Ethernet port or pulled by the radio from a remote device such as an SC-IOM. If using an SC-IOM to obtain GPS,

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 76 set the GPS mode to remote, the GPS Server IP to the IP address of the SC-IOM, and the Port to 2947. o RS-232: The RS-232 mode provides a wireless serial connection between any two serial devices connected to StreamCaster radios on the network. In this mode, the user must configure the RS-232 protocol parameters shown in Figure 28 above. The transport protocol for the serial data can be set as either TCP or UDP. For data that is sensitive to latency such as command and control data, UDP is recommended. For data that cannot tolerate any data loss, such as telemetry data, TCP is recommended.  The Peer IP should be the IP address of the radio on the other end of the RS-232 communication.  The Peer IP can be the native or virtual IP address, but must be consistent at both ends.  Baud rate must match the baud rate of data being sent from the device.  Note – An additional ‘null modem’ cable may be needed at either end, depending upon whether connected device is acting as a terminal or as a control (DTE or DCE) o Debug: The debug mode is used to gain terminal access to the StreamCaster radio and is available for debug or interface purposes (API commands). The user’s terminal client should be set to a baud rate of 115200 for console access to the radio. o Disabled: This mode completely disables the serial terminal of the radio.  Apply: Apply the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 77 USB Status (3822/4200/4400): The USB port on the 3822/4200/4400 can auto-detect whether the connected device is a USB host or client device. The USB cable should not be unplugged while the radio is running. 5.1.7 Node Diagnostics Figure 29 Node Diagnostics Configuration Page The Node Diagnostics page allows the user to specify an IP and Port number for Temperature and RSSI (Receiver Signal Strength Indication) reports to be delivered to. This is useful for users

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 78 that intend to feed this information into some other platform for analysis and recording. Section 8 gives more information on the format of streaming reports. Temperature Thresholds: In addition to receiving temperature reports, this page can be used to set minimum and maximum temperature thresholds for the radio. The StreamCaster™ family of radios is equipped with on board temperature sensors which are monitored to prevent overheating. Once a radio reaches the maximum temperature threshold, the radio will begin to reduce its transmission time until the temperature falls below the minimum temperature threshold. By default, the min and max values are 75C and 85C respectively. RSSI Reporting Configuration This setting allows the users to report the RSSI values every few milliseconds base on users setting. LED Configuration: This setting allows the user to disable or enable the LED on the faceplate of the radio. Voltage Monitor: Radios built on or after Jan 1, 2015 have the ability to monitor the input voltage, displayed here.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 79 5.1.8 BDA Support Figure 30 BDA (Bi-Directional Amplifier) Support Configuration Page The BDA Support page is used to configure the radio to work with an external bi-directional amplifier. These settings should be configured before connecting the amplifier to the radio.  Auto Noise Estimation: When enabled, the radio can automatically estimate the noise in the channel, including any amplification due to the external amplifier. It is preferred that this remain disabled and the LNA gain values be manually input further below, but if the LNA gain values are not known, this can be used instead.  PA Mode: Either set to “No PA” when there is no amplifier present or “Basic Mode” when using an external amplifier. Basic Settings:  PA Gains for Channels 1-4: Enter the gain (dB) for the power amplifier connected to each channel of the radio.  LNA Gains for Channels 1-4: Enter the gain (dB) for the LNA connected to each channel of the radio.  Maximum PA Output Power Per Channel (dBm): Enter the maximum output power for each PA.  Apply: Apply the new values but does not save them to flash.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 80  Save and Apply: Save the new values to flash and apply. 5.1.9 Build Information Figure 31 Build Information The ‘Build Information’ page provides information about the hardware and firmware loaded onto the radio, as well as the changelog of the currently loaded and past firmware revisions.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 81 5.1.10 Security The Security section of StreamScape allows users to enable/disable encryption, upgrade radios, and load license files for enabling features such as AES encryption. Encryption: Figure 32 Security (Encryption)  Encryption: Enable or disable encryption.  FIPS Mode: Enabling FIPS mode is the first step to making the radio FIPS compliant (see Section 6.1 Enable FIPS Mode for details). Enabling/disabling will require a reboot and will erase all setting profiles, reset the encryption key, both SSH keys, the HTTPS certificate, and the login passwords to their factory default. Enabling will also turn on HTTPS and Login Authentication. After reboot, the operator must perform the following steps to complete the FIPS compliant process. o Update the web login password to something other than “HelloWorld” o Create new SSH keys and HTTPS certificate. o Update encryption key or click “Generate Encryption Key” and save.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 83 Upgrade Network: Figure 34 Security (Upgrade Network) Starting with firmware version 3.12.6.8, multiple radios within the same network can be upgraded all at once. Users can simply choose the appropriate firmware file for the corresponding radio models to apply the upgrade to all the radios in the network. Currently, this feature is not available in HTTPS mode. License:

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 84 Figure 35 Security (License) Features such as encryption levels and frequency ranges can be enabled by license keys obtained from Silvus. New license keys can be uploaded to the radio on this page. Factory Reset: Figure 36 Security (Factory Reset)  Restore Factory Default: Restores all settings to default except those related to security (such as login passwords, encryption keys, FIPS mode, etc.). This is useful if the user changed some advanced settings and now they don’t know how to get to the defaults.  Zeroize Security: This will set login passwords and all security keys to their defaults. This includes the Encryption Key, SSH Login Key, SSH Host Key, HTTPS Certificate, and

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 87 Figure 38 (Key Management) This page is used to manage the radio’s SSH login keys, SSH host key, and HTTPS Certificate. All key pairs used are elliptic curves.  SSH Login Keys: In order to SSH into the radio, you must first generate a key pair and upload the public key onto the radio. A common way this is done on a computer is through the command `ssh-keygen -t ecdsa -b 521`. You will need to do this for each machine that wants to SSH into the radio, or you can share a single key pair amongst machines.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 88  SSH Host Key: This key is used for authenticating the radio to all machines that want to connect to it via SSH. A common way this key is generated on a computer is ‘openssl ecparam -name secp521r -genkey -noout -out yourfilename`. You may either upload your own key or generate one on the radio. Once you upload/generate a new key, the previous one is gone. You can get the original key by Factory Reset -> Zeroize. (Note that the generated text from the above command will encode both a private and public key in the text).  HTTPS Certificate: This certificate is used to establish a HTTPS connection. If you are using a factory default or radio generated certificate and haven’t added an exception of this certificate to your browser, you will see a message like below from your browser. This is because the certificate is signed by the radio and not a trusted Certificate Authority. You can bypass this by clicking “ADVANCED” in chrome, (or adding an exception in Firefox). The simplest way to generate a new certificate is to click “Generate Certificate and Save” button. If you are on HTTPS when you do this, you must also refresh the page. If you want to generate your own certificate, you must first generate a key pair (secp256r1, secp384r1, or secp521r1). Then create a X.509 certificate and append your private key to it. Copy the certificate text to the “Add a HTTPS Certificate” section, then click “Add Certificate and Save.” Figure 39 (Chrome Browser Warning)

Radios will only communicate with other radios that are subscribed to the same ‘Multicast Group’. Radios can be active in multiple talk groups.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 90 Multicast Group – Input the IP address of the multicast group. Radios will only communicate to radios within the same group. There are three different modes to select which dictate how a radio behaves within a group:  Active: Radio may send and receive PTT audio on this group.  Inactive: Group is disabled, no PTT audio will be sent or received.  Monitor: Radio may listen to PTT audio from other users on this group, but may not talk. Mic Type – Supported MIC types are Moving Coil or Condenser. The input amplification is adjusted based on the Mic Type chosen on this page Mic Bias Voltage – Options are 90% (3V) or 65% (2.15V). Audio Encoder Type – Default option is G.722 (high quality). G.711 is also supported for backwards compatibility with the SC-IOM Speaker Volume – Moving slider adjusts the gain on the speaker Mic Volume – Moving slider adjusts the gain on the microphone Beep Volume + PTT Override – When the PTT button is pressed while another user is speaking, a warning beep will be played. This setting controls the volume of the Beep as a percent (%) of the speaker volume above. Pressing the PTT button three times (and holding on the third) within 1s will allow a user to override the channel and speak. PTT HQ Link Notifications – When the PTT button is pressed twice within 1s, an audio notification will read out the SNR level to the user-specified HQ node. If the level transitions option is enabled, the notification will be played automatically when the SNR crosses the specified thresholds. The SNR thresholds can be set by first choosing the number of levels desired, and then moving the sliders accordingly.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 91 5.1.12 Spectrum Scan Figure 41 Spectrum Scan Results The spectrum scan feature turns a Silvus network of radios into a distributed spectrum analyzer. When a scan is initiated, each selected radio in the network will go offline, perform a scan of the requested range, and report back. Figure 41 Spectrum Scan above shows the results from a scan of a network of 6 radios. The checkboxes at the top allow users to show or hide plots from specific radios. The three plots provided are: Average – Displays the average power over the time duration specified in the settings. Peak – Displays the peak power seen at any point during the scan for each frequency. This is the equivalent of the ‘Max Hold’ feature on common spectrum analyzers. Threshold – Displays the duty cycle of interference stronger than the user specified ‘Threshold’ power. In the example above, the threshold was set to 5dB. The plot is showing the percentage of time that the measured power is more than 5dB above the radio’s noise floor.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 92 Settings: Figure 42 Spectrum Scan Settings Clicking the settings button at the top left of the window will show the settings pane as shown in Figure 42 Spectrum Scan Settings The node list shows the list of nodes currently connected into the mesh network. Any nodes selected will be used as part of the spectrum scan. Nodes that are unchecked will resume normal operation. Note that an unchecked node will continue transmitting in the frequency channel it is operating in and its transmission will show up in the scan results of scanning radios. Mode – Set to Spectrum Scan or Zero Span. Spectrum Scan mode provides plots of signal strength over frequency. Zero Span provides a plot of power over time in a 20MHz Bandwidth (see Figure 44 Zero Span Results below. Spectrum Scan Mode: Center Frequency – Specify the center frequency of the scan.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 93 Span – Specify the span of the scan, centered on the center frequency. (e.g. Center freq of 2450MHz and span of 100MHz will scan 2400-2500MHz). A large span will take longer to complete. Antenna Mask – Choose which antenna on the radio to use for scanning. If there are 2 antenna radios in the network antenna 1 or 2 must be chosen. Resolution Bandwidth – Specify the RBW for the scan. A smaller RBW will provide a more detailed plot, but will take longer to complete the scan. 625KHz is a good balance between scan detail and time of scan. Threshold – Specify the threshold for measurement of the duty cycle of interference. Duration – Duration of each scan. A longer duration will provide better accuracy but will take longer to complete. Approximate time for scan – Approximate time that the network will be down for the scan to complete. Zero Span Mode: Figure 43 Zero Span Settings

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 94 In the Zero Span mode, the radio will provide a plot of the power measured in a 20MHz bandwidth across time. Zero Span can only be conducted on one radio in the network at a time. Other radios in the network will continue to operate and transmit so a zero span scan should not be conducted within the same frequency that the mesh network is operating in. Center Frequency – Specify the center frequency of the scan. Sampling Rate – Set the sampling rate of the scan. (0.3Msps recommended) Antenna Mask – Choose which antenna on the radio to use for scanning. If there are 2 antenna radios in the network antenna 1 or 2 must be chosen. Duration – Duration of each scan. A longer duration will provide better accuracy but will take longer to complete. Approximated time for scan – Approximate time that the network will be down for the scan to complete. Figure 44 Zero Span Results

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 96 If the radio boots up in position “Z,” MPS will be disabled until the radio is rebooted in another position. 5.1.14 Admin Settings Figure 46 Admin Settings The Admin Settings page provides the option of password protecting access to Streamscape. There are three usernames, Basic, Advanced, and Admin, each with increasing privileges on the GUI and backend API. For example, only Admin can access the Security tab. To enable, set the Login Authentication to Enable and provide a password. Once Login Authentication is enabled, access to Streamscape will require a username and password as shown below. To change the password, click “Change Password,” then select the username whose password will change, type the Admin password, then type the new password. Figure 47 Login

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 97 Reset Password: Figure 48 Reset Password If a user forgets the password, click “Forgot Password.” They can reset the password using a USB flash drive and a password reset key provided by Silvus. On the USB, the password reset key file must be called reset_pass.txt.signed. Note that since the SC3500 and SC3800 do not have USB ports, you will not be able to set a password for these radios. This will set login passwords and all security keys to their defaults. This includes the Encryption Key, SSH Login Key, SSH Host Key, HTTPS Certificate, and Encryption Key Volatile. It will also erase all settings profiles. Also, if FIPS mode is off, it will turn off HTTPS and login mode. The current FIPS mode will not be changed.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 98 5.2 StreamScape Network Manager Silvus’ StreamScape Network Management Utility was designed to monitor the status of a Silvus mesh network in real-time. The graphical interface network map, shown in Figure 44, allows users to quickly and effortlessly view the network topology and configure key parameters of the network. For ease of use, the Silvus StreamScape utility is designed to be accessible from a Firefox or Chrome web browser.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 99 5.2.1 Network Topology Figure 49 Silvus StreamScapeNetwork Manager The network topology provides the user with real-time visual feedback of the network. Users will be able to determine several network characteristics at a glance with the following features:  Color Coded Link Health – Color coding of each link in the network allows the user to quickly identify the weak links within a network. A link between two nodes will transition from green to yellow to red as the link weakens while also displaying the SNR of the link. This can be seen in Figure 50.  Route Health – The Silvus StreamScape Utility will alert the user when too many packets are being routed through a single node. In such cases, a node will change from green to yellow to red as the packet queue increases (see ‘1132_4.108’ and ‘1131_4.107’in Figure 50). This will

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 100 allow the user to recognize the issue and rearrange the network accordingly. Table below also shows the values for each scenario. ` Figure 50 Example Network Topology Green Orange Red Link >20dB 10-20dB <10dB Node <10 Packets in Queue 10-100 Packets in Queue >100 Packets in Queue Table 21 Color Coding for Links and Nodes

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 101  Routing Information – The user can view the routing path between any 2 nodes within a network by simply specifying the source and destination node in the Control Panel on the left hand side. The path will turn bold as shown in Figure 51 for the path from ‘node4411’ to ‘node4569’. Figure 51 Routing Path  Custom Node Naming – Naming each node in the network is as simple as double-clicking on the node name and typing in a new name as shown in Figure 52. Once this is done, the user need to hit enter to keep the node name. Otherwise it will change back to what it was. This feature enables quick identification of nodes in the field and is especially useful in mission critical situations with many mobile assets. The user can click on the ‘Save Labels in Flash’ button in the left pane to store the node names to the radio’s flash memory. This will store the names on the radio even after the radio is powered off. The saved labels can also be cleared back to the defaults by clicking ‘Clear Labels in Flash’. The node labels set in one radio can also be broadcasted to other radios in the network by clicking the ‘Broadcast Node Labels’ button.

Users simply need to check off the parameters they wish to be updated across the network and click on Apply to apply but not write new values to flash or Save and Apply to apply and save values to flash. The Broadcast Update Interval field determines how often, in seconds, the new parameters will be broadcast to the entire network. A list of all nodes will appear on the right with a check box next to each node. This box will be checked off as each node receives the update. Figure 59 Network-wide Setup

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 111 5.2.4 Per-Node Setup The per-node setup can be used to modify key parameters of individual nodes within the network. As shown in Figure 60, users will see a list of all nodes available within the network. The directly connected node is listed first with the rest ordered lexically. From here, users can click on an individual node and modify its parameters. Any parameters changed from this interface can either be applied or saved and applied. In addition, this page can be used to upgrade a radio’s firmware by simply choosing the upgrade image from your desktop and uploading it to the radio. This field can be used to upgrade the radio root file system, linux kernel, or uboot. The upgrade system accepts the root file system image for upgrade or a tar file containing up to 3 files (uboot, kernel, rootfs) for upgrade. A radio reboot will be required after update before the changes take effect.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 112 Figure 60 Per-Node Setup 5.2.5 Map Overlay The Map Overlay page provides an easy to use method of tracking the location of nodes in real-time. Nodes with GPS modules attached will be placed on the map as shown in Figure 61.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 113 Figure 61 Map Overlay For convenience, a small copy of the network topology is displayed on the right-hand side of the page. This allows users to clearly view the network characteristics in instances where nodes are physically close to one another and difficult to distinguish on the map overlay. 5.2.5.1 Map Options There are 4 map options currently available in the Map Overlay view. The default map is OpenStreet Maps. OpenStreet Maps and OpenStreet Maps Silvus can be saved to the radio’s internal memory for offline use. For instructions to Download OpenStreet Maps into the radio, see section 5.2.5.2. OpenStreet Maps Silvus is a version of OpensStreet maps which is hosted

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 114 on Silvus’ servers in case of an interruption in service with OpenStreet Maps. The Silvus maps currently only cover the United States. In Addition to OpenStreet Maps, Google Maps and Google Satellite are also available. This can be changed by clicking the ‘+’ symbol at the top right of the map: Figure 62 Google Maps Note that Google Maps and Google Satellite require an active internet connection on the viewing computer. These maps cannot be saved for offline use. Offline Map Image: In addition to the preset map options, the user can also upload a custom image or blueprint in place of the map.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 115 Figure 63 Offline Map Image To upload a custom image (800 x 600 pixels recommended), first choose the file from your desktop. You will then need to provide the image bounds. These bounds will be the latitude of the left and right bounds of the image and longitude of the top and bottom bounds of the image. Once entered, click upload and there will now be a 4th option when clicking the ‘+’ at the top left of the map overlay.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 116 5.2.5.2 Downloading Maps An internet connection is required to obtain map data, however, users can cache map data on a node beforehand. For map caching follow these steps: 1. Attach the radio to a laptop and open the advanced tab. 2. Set the Virtual IP address, netmask and gateway to values appropriate for your local network. Your local network should be able to access the internet. 3. Attach the radio to your local network and open the Map Overlay tab. 4. Input the address of the location you wish to download 5. You now have two options for caching map data: a. Zoom/pan around the area you are interested in at the zoom level you will be using. This will automatically cache the map data at this zoom level. b. Fill in the radius field (in meters), set the Min/Max zoom levels and click on ‘Seed the Map’. This is a beta feature and will attempt to cache the entire area for all appropriate zoom levels. Users should be careful in using this feature since it may take some time and will use up the radio’s available memory. For reference, a radius of ~3000m will use approximately 5 percent of the total memory.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 119 6. FIPS Mode 6.1 Enable FIPS Mode The following steps are required to make the radio FIPS compliant. 1. Enable FIPS mode under Security -> Encryption tab. This will require a reboot and will erase all setting profiles, reset the encryption key, both SSH keys, the HTTPS certificate, and the login passwords to their factory default. It will also turn on HTTPS and Login Authentication. 2. After the radio comes back online, you will need to login to continue. You must change the default password of “HelloWorld,” for all three users. Do this by clicking “Change Password,” and then follow the instructions in section 5.1.13 Admin Settings. 3. Next go to Security -> Key Management. You must change the SSH Login Key, SSH Host Key, and HTTPS Certificate from their defaults. See section 5.1.10 under Key Management for details. 4. Now you must create an encryption key that will be shared amongst all radios on a network. For initial setup, you must have a direct connection to each radio from your laptop (since a mesh cannot be formed without a shared encryption key). On the first radio, click Generate Random Key, then click Apply. For the rest of the radios, instead of clicking Generate Random Key, copy/paste the first generated key to the rest of the radios under the same section. o If you want to change the encryption key after initial setup, you must carefully sequence the order in which you change the keys if you don’t have a direct connection to all radios. First change the radios at the very edge of the network. As soon as you do this, those radios will be disconnected from the network. Now change the new radios at the edge of the network. After you have changed the encryption key for all radios on the network, they will all reconnect again. 6.1.1 Potential User Errors o Do not use the same encryption key you were using in non FIPS mode because these may have been broadcasted in plain text. Generate new ones once in FIPS mode.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 120 6.2 List of Security Parameters o Passwords (Basic, Advanced, and Admin User): Used to login to the radio as either Basic, Advanced, or Admin user. o Encryption Key (also called RF-Auth-Key): This is a 256-bit sequence, represented as 64 hex numbers. It is used to establish an encrypted connection in a network. o SSH Host Key: This key is used for authenticating the radio to all machines that want to connect to it via SSH. o SSH Login Key(s): These are ecdsa private/public key pairs. They are used for authorizing SSH access to the radios. These key pairs are used instead of passwords since they are more secure. o TLS Host Key (also called HTTPS Certificate): This certificate is used to establish a HTTPS connection. The underlying elliptic curve keys can be either secp256r1, secp384r1, or secp521r1.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 121 7. Wired Backbone Wired Backbone extends the StreamCaster mesh functionality over LAN (Ethernet) and WAN (Internet) links. This feature is transparent to end-users - they do not have to re-configure their devices in any manner to use this feature. The StreamCaster routing protocol will automatically detect and route data on wired links to preserve air bandwidth. 7.1 LAN Backbone The LAN backbone feature allows more than one radio to be connected to a LAN. 7.1.1 Implementation One of these radios must be configured as a “gateway” radio. This radio then begins listening promiscuously on its ethernet interface to “register” all devices on the LAN as being connected to the gateway radio. At the same time it auto-detects other non-gateway radios connected to the LAN and establishes “wired” links to them. StreamScape Web GUI will show LAN links with SNR of 150 dB to differentiate from wireless links. The non-gateway radios do not register any devices, they merely act as relays. The gateway radio will forward traffic originating from the LAN, destined for a device attached to a wireless radio, to the non-gateway radio that is closest to the destination. Similarly, any traffic originating from a device attached to a remote wireless radio, destined to a device on the LAN will be forwarded by non-gateway radios to the gateway radio. The gateway radio will then send it to the device. Currently we support data rates of up to 65 Mbps on the LAN without encryption. Since all LAN traffic goes via the gateway radio, this is the upper limit of all traffic that can enter or go out of the LAN from/to devices connected to wireless radios. Of course, this limit does not affect the throughput between two devices connected directly to the LAN backbone. 7.1.2 Use Case Consider the following scenario. A business wants to do video monitoring of its grounds. High speed LAN hookups are available only in the HQ building. They want to use the StreamCaster radios on towers to

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 122 provide complete coverage of the grounds. All video feeds are sent back and displayed at the HQ. To conserve air bandwidth and possible interference to other users, we want video data to go through the high speed LAN backbone as much as possible. The below diagram shows the scenario. Towers 1-3 are equipped with IP cameras attached to StreamCaster radios 1-3. Radios 4-6 are mounted on three sides of the HQ building with their Ethernet interfaces connected to the high speed LAN. Tower 1 can only communicate wirelessly with radio 4, Tower 3 with radio 5 and Tower 2 with radio 6. Video from Tower 1 will flow wirelessly to radio 4, then via the LAN backbone to the HQ viewer which is also attached to the LAN backbone. Even though the radios 4-6 may communicate wirelessly, they will choose to do so via the LAN backbone. Figure 66 LAN Backbone Example

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 123 7.2 WAN Backbone with Roaming The WAN backbone feature allows the wireless mesh network to extend over Internet links. Multiple geographically separate “sites” can be connected into one single layer 2 network as long as each site has an uplink to the Internet. The roaming feature allows mobile devices connected to StreamCaster radios to roam from one site to another without any network re-configuration. 7.2.1 Implementation Each site wishing to become part of the wireless mesh needs to connect one StreamCaster radio to its LAN. Such a radio has to be configured to connect to a remote VPN server using the N2N protocol. Radios from multiple sites will be connected at layer 2 via the N2N VPN server creating a single broadcast domain for such nodes. By broadcasting routing packets in this domain, the nodes will auto-detect each other and establish WAN links. Such links will appear on the StreamScape GUI with a link SNR of 120 dB to differentiate from LAN links (150 dB) and wireless links. The N2N VPN server will try to establish peer-to-peer links between the radios if it can. Under some cases (e.g. symmetric NATs), this is not possible, in which case traffic between the peers is relayed by the N2N server. The N2N server can be hosted at any server with a public IP on the Internet. As a proof-of-concept, a server has been set up on Amazon Web Services. Currently we support up to 10 Mbps unencrypted between any two sites. 7.2.2 Use Case Consider a military scenario where a platoon of soldiers begins its mission at an HQ, then breaks up into two groups. Each group has at least one soldier with an uplink to the Internet (provided by a 4G card). The HQ also has an uplink to the Internet. Every soldier and the HQ have a StreamCaster radio attached to their devices. The soldiers in the two groups want seamless and transparent communication between 1) other soldiers in the same group 2) soldiers in the other group 3) back to HQ. Some lone soldiers (e.g. Soldier A with a StreamCaster radio) may break up from each group and move about on their own. As they get close to group 1, 2 or the HQ, they should be able to immediately establish communication and talk to all other soldiers in the network. The StreamCaster radios connected to the uplinks in Group 1-2 and the HQ will automatically connect and form WAN links.

StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 124 Note that the WAN and LAN backbone are complementary features. E.g. at the HQ, multiple radios can be connected to a LAN backbone so that any approaching soldier or group has a direct line of sight wireless connection to the HQ. Figure 67 WAN Backbone Example

Custom Frequency Plan 8.1 Accessing and Installing CFP Figure 68 Custom Frequency Page There are two ways to install the frequency plan. The first method is more simple. Users can simply click on Create Custom Frequencies next to the frequency selection window to get to the custom frequency page shown in Figure 63.  Add: Add the frequencies in the text box to the list  Download Plan: Download the frequency plan the radio is currently using  Remove Plan: Removing the entire frequency plan. If this field is left empty, the radio will use the default frequency plan.  Download Plan: Download the current frequency plan to a file that can be uploaded to other radios.

$StreamCaster MIMO Radio User Manual 9/4/18 10017C000 Silvus Technologies Confidential Page 126  Remove Frequency: Remove the currently selected frequency.  Custom Frequencies Plan Upload: Upload the selected frequency plan. The second method requires accessing the hidden Custom Frequency Plan page. Note radios on older firmware only support this method. The hidden Custom Frequency Plan page can be accessed via http://<radio IP>/custom_freq.sh The interface will allow an upload of a custom frequency plan file which should be in the following format: { "type": "custom_frequency_plan", "name": "cfp_example", "description": "CFP Example", "frequencies": [ "2412", "2417", "2422", "2427", "2432", "2437", "2442", "2447", "2452", "2457", "2462",$

Name/description can be changed) Custom Frequency Plan Text file example: https://drive.google.com/file/d/0ByThlCSjgHe1TDMtZ2xDXzhEblE/view?usp=sharing The numbers can be changed to the frequencies desired. The name of the text file does not matter in order to be utilized. After uploading the file, the web interface will be populated with the Custom Frequency Plan. Note: Once installed, the Custom Frequency Plan will be cross-checked with hardware capability and the licensed frequency range previously installed on the radio. The Custom Frequency Plan will only change what is displayed. It will not give new frequencies that are previously out of licensed range.

Streaming Response Some users may be interested in streaming specific information from the radio e.g. RSSI, noise floor, temperature, etc. After enabling the response they need using the above commands, the radio will transmit the desired information in the form of UDP packets to a specific IP address and port. The format of each report message will be in the type-length-value format as shown below: TYPE LENGTH VALUE TYPE LENGTH VALUE …  TYPE and LENGTH will be 16-bit unsigned integers in network-endian format.  TYPE indicates the kind of information being transmitted. Pre-defined types are listed later in this document.  LENGTH indicates the length of the VALUE field in bytes, including the terminating null byte.  VALUE will be ASCII-encoded text terminated with a null byte ('\0').  A single report will comprise of a set of type-length-value fields beginning with a “begin” report type. It will have a type which is specific to the type of report being generated, length of 1 byte and a value of an empty string (“”). Note the empty string is still null terminated.  Each report will end with an end of report which has type 1 (type = end of report, length = 1, value = "").  The empty string listed above has a NULL character and has length 1. Any length number in the streaming report includes the NULL character  A UDP packet may contain more than one report.  The UDP packets have a maximum size of 1400 bytes.$
