The WiNetworks WiN5200 is a member of the Win-Max™ E family, a line of mobile WiMAX broadband wireless access systems based on the 802.16e mobile WiMAX standard. The Win-Max™ E family is detailed in the System Description manual of WiNetworks. This manual assumes that users have some experience with WiMAX technologies and procedures. While some safety precautions are reviewed here, this manual assumes that installers have been trained in safe installation practices. Users, who are new to WiMAX technologies and service procedures, should not rely on this manual for comprehensive guidance. 1.2 General Description The WiNetworks WiN5200 ODU is a member of the Win-Max™ E family, a line of WiMAX Broadband Wireless Access systems based on the 802.16e mobile WiMAX standard, specially designed for quadruple-play applications. WiN5200 is a high-performance outdoor unit that provides complete 802.16e mobile WiMAX broadband wireless access functionality to a range of indoor multi-service gateways. The WiN5200 enables the full scope of triple-play (including telephony, data, Video-on-Demand) over the WiMAX network. In the home, triple play services are distributed to a single gateway for a simple home-networking solution. The WiN5200 is based on the IEEE 802.16e standards to effectively meet the unique requirements of the wireless Metropolitan Area Network (MAN) environment and to deliver broadband access services to a wide range of customers. Specifically designed for point-to-multipoint broadband wireless access applications, the WiN5200 provides efficient use of the wireless spectrum, supporting a range of user environments. The access and bandwidth allocation mechanisms accommodate hundreds of subscriber units per sector, supporting differentiated services to a multiple of end-users.

WiN5200 Introduction | 7 1.2.1 Features • Intelligent WiMAX subscriber unit for wireless triple-play service delivery • Outdoor unit with ETH interface to indoor unit • Automatic, self-configured, plug-n-play • Supporting 1.X, 2.X and 3.X GHz bands 1.3 Package Components and Unpacking Check that the package contains: 1. WiN52xx ODU with integrated flat antenna 2. Pole/wall mounting hardware In case of damage, contact the shipping company. 1.4 Safety Information RF Exposure The WiN5200, an outdoor CPE, is compliant with the requirements set forth in CFR 47 section 1.1307, addressing RF Exposure from radio frequency devices as defined in OET Bulletin 65. The outdoor CPE should be positioned more than 0.6 feet (20 cm) from humans. Lightning Protection When WiN5200 is installed in an outdoor location, all indoor components (Ethernet, power supply) should be connected through a lightning protector. The purpose of the lightning protection is to protect people and equipment located indoors from lightning that might strike the WiN5200 or its outdoor cables. Therefore, the lightning protector device should be installed indoors, as close as possible to the point where the cables enter the building. The lightning protector can also be installed outdoors, as long as the cables that lead from it indoors are well protected from lightning between the box and the building entrance. Power Cord Protection The WiN5200 should always be connected to the WiN1010 data adapter for both power supply and data transfer purposes. Any other type of connection/application of the WiN5200 and/or WiN1010 is not allowed. Route all power supply cords so that people cannot walk on them, or place objects on or against them. This can pinch or damage the cords.

WiN5200 Product Description | 9 2 Product Description

WiN5200 Product Description | 10 2.1 Introduction The WiN5200 ODU CPE is an IEEE 802.16-2005 compliant wireless device for deployment of point-to-multipoint (PMP) and point-to-point (PTP) network architectures. The WiN5200 ODU CPE is an outdoor device. The WiN5200 ODU CPE is WiMAX Forum 802.16e Wave 2 (MIMO) Certified subscribers. Each subscriber registers and establishes a bi-directional data link with the base station sector controller. The CPE terminals are grouped into two classes, Outdoor CPEs and Residential Gateways (RG) which are indoor units. The relationship between all the units is illustrated below. HouseRGWiN1030-1RGWiN1020-1RGWiN1010-1CPEWiN52xxBSTWiN70xxCPEWiN52xxCPEWiN52xx Figure 2-1: Functional Overview of the CPEs

WiN5200 Product Description | 12 Figure 2-2: WiN5200 Block Diagram 2.4 Features 2.4.1 Mobile WiMAX Wave 2 MIMO Features Multiple-Input, Multiple-Output (MIMO) describes systems that use more than one radio and antenna system at each end of the wireless link. In the past it was too costly to incorporate multiple antennas and radios in a subscriber terminal. Recent advances in radio miniaturization and integration technology now makes it feasible and cost effective. Combining two or more received signals has the immediate benefit of improving received signal strength, but MIMO also enables transmission of parallel data streams or greater throughput. For example, in a 2 x 2 MIMO (two transmit and two receive elements), dual polarization point-to-point system, the carrier’s allocated frequency can be used twice, effectively doubling the throughput data rate. In point-to-multipoint systems employing MIMO, each base station antenna transmits a different data stream and each subscriber terminal receives various components of the transmitted signals with each of its subscriber antennas as illustrated in the figure below. By using appropriate algorithms, the subscriber terminal is able to separate and decode the parallel simultaneously received data streams.

WiN5200 Product Description | 13 Figure 2-3: MiMo Antenna System 2.4.1.1 Space-Time Coding Space-time coding (STC) is a technique for implementing transmission diversity. Mobile WiMAX uses transmit diversity in the downlink direction to provide spatial diversity that enhances the signal quality to a specific subscriber located anywhere within the range of the antenna beam. Although providing less signal gain than beam-forming, transmit diversity is more robust for mobile users since it does not require prior knowledge of the path characteristics of a subscriber’s particular frequency channel. One such STC technique, known as the Alamouti Code, was published in 1998[4] and has been incorporated into the WiMAX 16e standard. MiMo MiMo

WiN5200 Product Description | 14 2.4.2 Security Security was a key failing of older broadband wireless systems of the past. The why of it is easy to comprehend---any network that transmits its data across wireless signals rather than wires is inherently more open to interference, intrusion or assault. This does not mean solid broadband wireless security is impossible, just much more difficult. As broadband wireless networks have matured security features have improved. With the advent of WiMAX, the security toolsets available to broadband wireless service providers have reached all time highs of functionality. Today's WiMAX networks can be secured more effectively than ever before. WiMAX and IEEE 802.16 Security Sub layer provides for privacy, authentication and confidentiality across the broadband wireless network. Defined initially by IEEE 802.16-2004 and then corrected and amended by Corrigendum 1 and IEEE 802.16e-2005 respectively, the Security Sub layer now supports Fixed and Mobile operation. There are two major differences between the standards. The first difference is that the security mechanism of the IEEE 802.16-2004 is based on the DOCSIS standard. In the 802.16e-2005 many changes have been made in the security mechanisms. The second difference is in the flexibility of SS's connection characteristics with the BST. The IEEE 802.16-2004 only supports fixed access. In fixed access, an SS cannot mitigate to the air interface of a new Base Station (BST) without performing the network entry again after a connection termination. The IEEE 802.16e-2005 supports mobile access. Mobile access enables an SS to move between various BST cells while keeping the connection established. There are five primary aspects of WiMAX security that should be considered when designing a security plan for a WiMAX network. These range from mitigation techniques at the physical layer to improved wireless authentication and encryption to intrusion protection and data transport security. At each level, choices in implementation and security levels can be made; although in the case of the physical layer options are limited. 2.4.2.1 Physical Layer Security There are two basic types of attacks that can affect the physical layer of WiMAX. One is jamming and the other is packet scrambling. The first is relatively straightforward, and is sometimes the result of interference rather than an attack. Jamming consists of a stronger signal than the WiMAX network overwhelming network data feeds either in intermittent bursts or with sustained carrier waves. Since most WiMAX network services are delivered over licensed bands (currently 3.5 GHz internationally and 2.5 GHz both internationally and in the US), this offers spectrum relatively quiet from accidental interference. Accidental interference in licensed spectrum cannot always be completely discounted as there is a possibility of second and third harmonic interference waves, for example, from much lower frequency signals if those are in close proximity to the WiMAX antenna systems or that cross them with a signal close enough in physical proximity to locally overload the WiMAX signal. In practice, this is rare.

WiN5200 Product Description | 15 Packet scrambling is an attack that occurs when control packets in the respective downlink and uplink subframes are sniffed then scrambled and returned to the network. This attack is much harder to mount than a jamming attack. Since most WiMAX networks today use time division duplexing (TDD), to include the Win-Max™ system, an attacker can parse this timing sequence and capture control data, the preamble and map, scramble them and send them back with correct timing to interrupt legitimate signal, resulting in slowdowns and effectively lowered bandwidth. Intercepted and scrambled packets are possible with frequency division duplexing (FDD) as well which transmits both the uplink and downlink simultaneously, but it is even harder to exploit this attack than with TDD systems. While it may seem the physical layer is inherently most vulnerable as the security elements of WiMAX are located at higher layers, the fact is hackers can often find lower hanging fruit in terms of useful exploits higher in the stack, because as WiMAX supports multiple selections on what service providers can choose to implement in terms of authentication, sometimes the door can be left open for them by the choices made. 2.4.2.2 Authentication Traditionally the first level of security authentication for older broadband wireless technologies has been MAC authentication and WiMAX supports this, although providers don't settle for this method. This technique allowed service providers to log permitted MAC device addresses and allow only those addresses to access the network. Hackers long ago figured out how to spoof these. If a base station is not set up with adequate authentication measures, an attacker can capture control packets and pose as a legitimate subscriber even with older MAC device authentication enabled. A second, newer and much better choice, embraced by the Win-Max™ system, is the built in support for X.509 device certificates embedded with the use of extensible authentication protocol---transport layer security (EAP-TTLS) method, added with the 802.16e standard and WiMAX Forum. Enter the EAP-TLTS authentication method. This technique allows both the subscriber and the base station to authenticate each other using an X.509 method for both, in addition to a subscriber authentication which is based on well-known subscriber authentication techniques such PAP and MS-CHAP. MAC control headers are never encrypted in WiMAX, however with EAP carriers can choose to authenticate them (but they don't necessarily have to). This capability adds an additional layer of authentication confirmation. It's an operator specific guideline decision and is tunable in the Win-Max™ system. 2.4.2.3 Encryption Clearly the first layer of defense for WiMAX operators is to authenticate a legitimate user on its network. However, WiMAX, with its 802.16e ratification, offers top line tools for encryption of data. Older wireless iterations used the data encryption standard (DES) which relied on a 56-bit key for encryption. This is largely considered obsolete. WiMAX 802.16e certainly supports DES (3DES) but it also adds support for the Advanced Encryption

WiN5200 Product Description | 16 Standard (AES) which supports, 128-bit, 192-bit or 256-bit encryption keys. Also AES meets the Federal Information Processing Standard (FIPS) 140-2 specification, required by numerous governmental branches. This technology, which requires dedicated processors on board base stations, is robust and highly effective. Traffic encryption may be employed per 802.16 Service Flow and is subject to operator policy. The relevance of encryption to the network operator deployment is questionable. In the past, for example, many cellular carriers focused on authentication and mostly ignored encryption. Whether that will change as mobile service providers ramp up more broadband applications is an open question. The downside to these heavy computing tasks (i.e. authentication and encryption) is that all of this requires processor cycles, which may affect the performance of the system. Nevertheless, the Win-Max™ system and especially, the SS and BST, which are the entities that take active role in heavy security-related computations, were built bottom to top with a design goal of offloading heavily computing tasks from the host processor to a specific circuit. Consequently, no performance degradation is neglected. 2.4.2.4 Third Party Intrusion Protection We examined WiMAX authentication schemes, which are a major component of a secure network. And we also spoke of data encryption. Clearly, WiMAX possesses solid tools already built in. But there are considerations beyond just good security that can drive a migration to third party intrusion detection and protection tools---namely business case elements. Intrusion protection is however, not data protection. These are two different classes of solution. Certainly, a good third party intrusion protection can monitor and secure a network's authentication. However, many solutions also offer worm protection, Trojan horse protection, defenses against viruses, backdoor exploits and denial of service attacks to name a few. Some of these elements are almost a business necessity for a wireless service provider and may justify the cost of an additional security suite initially. For other companies, a migration strategy to enhanced tools makes the most cost effective sense. A good place to start is examining market and service scenarios. If your customer base is highly sensitive to data integrity (financial sector or hospital customers) third party intrusion prevention systems can help segment customers from each other better as well as secure them from outside attack. Or in another example, a mobile network that offers just Internet access and voice may wish to abrogate responsibility for data encryption and use session initiation protocol (SIP) signaling for its VoIP and WiMAX native authentication tools. Referring to encryption, clearly an AES supported data encryption system gives WiMAX excellent security in this regard. However, additional solutions that meet customer needs such as virtual private networks may enhance the business model and provide additional source of revenue.

WiN5200 Product Description | 17 In the following two clauses, two revolutionary applications targeted at specific market segments are described. These applications of WiMAX for DBS & DVB-T operators and WiMAX for Cable operators distinguish WiNetworks from other players in the WiMAX industry. Network Access Providers can easily provide fast Internet and advanced data service to their deployed network by using the WiNetworks WiMAX-based technology solution. 2.4.3 Time Division Duplexing (TDD) The WiN5200 CPE uses time division duplexing (TDD) to transmit and receive on the same RF channel. This is a non-contention based method for providing an efficient and predictable two-way PTP or PMP cell deployment. All uplink and downlink transmission scheduling is managed by the base station. The base station sends data traffic to subscribers, polls for grant requests, and sends grant acknowledgements based on the total of all traffic to all subscribers. 2.4.4 Coding Rate Each burst of data transmitted over the wireless interface is padded with redundant information, making it more resistant to potential over-the-air errors. The coding rate is the ratio of user data to the total data transmitted including the redundant error correction data. The base station supports coding rates of 1/2, 2/3, and 3/4. 2.4.5 Modulation The modulation technique specifies how the data is coded within the OFDMA carriers. The base station supports QPSK, 16 Quadarature Amplitude Modulation (QAM), and 64 QAM modulations. 2.4.6 Convolution Coding Error Correction Convolution Coding (CC) error correction is enabled for all traffic rates. This low-level process can correct bursts of errors in received messages and reduce the number of retransmissions.

WiN5200 Product Description | 18 2.5 Deployment Models The CPE supports point to point (PTP) and point to multipoint (PMP) deployment scenarios. 2.5.1 PTP Deployment When deployed in a PTP configuration the base station establishes a dedicated bidirectional link to a single subscriber. The PTP deployments typically use a directional narrow beam antenna for both ends of the link. 2.5.2 PMP Deployment When deployed in a PMP configuration the base station establishes bi-directional links to more than one subscriber. PMP deployments typically use a wide beam (sector) antenna at the base station and a narrow beam antenna at the subscriber. Service flows are used to police service level agreements for each subscriber. 2.5.3 Non Line-of-Sight The WinMAX product family supports line-of-sight (LOS) and non line-of-sight (NLOS) operation. A clear LOS link has no obstacles within 60% of the first Fresnel zone of the direct path. A wireless link is considered non-LOS if natural or man-made structures block the visible path between the base station and the subscriber. In this case, a wireless link can be established only if a reflective path can be established between the base station and subscriber. 2.5.4 Channelization The CPE is a frequency-specific system, with the frequency band defined by the PHY unit. The use of the operating band must be in accordance with local regulation requirements. The CPE divides the available frequency band into channels. Allocation of channels during deployment is dependent on spectrum availability in the licensed band and local licensing requirements and conditions. Channel selection allows planners to obtain the maximum geographic coverage, while avoiding frequency contention in adjacent sectors.

WiN5200 Product Description | 19 2.6 Service Flows Service flows are a key feature of the 802.16e standard. A Service Flow represents a unidirectional data flow having separate QoS settings for uplink and downlink. Service flows provide the ability to set up multiple connections to each subscriber in a sector. Separate service flows can be established for uplink and downlink traffic, where each service flow is assigned a unique service level category and separate QoS settings. This feature allows segregation of high-speed/high-priority traffic from less time-critical flows. 2.6.1 Service Flow Classification Data packets are forwarded based on classification rules. Classification rules require examining each packet for pattern matches such as destination address, source address, IP TOS, or VLAN tag. All classification is defined at the base station and the classification parameters are downloaded to the subscriber. 2.6.2 Dynamic Service Addition Service flows are defined and stored in the base station. For each service flow to be established, the base station sends a setup message to the subscriber specifying the required set of QoS parameters. The subscriber responds to each request by accepting or rejecting the setup message. A service flow may be pre-provisioned or can be dynamically created and deleted without service outage. This is useful for supporting multiple subscribers in a single sector. New subscribers can be added and existing subscribers can be removed or have service levels modified. Setup messages are sent by the base station following any subscriber power-cycle, loss and recovery of the wireless link to a subscriber, or any service flow add/delete operation at the base station. 2.6.3 Default Service Flows Default UL/DL service flows are created automatically for each registered subscriber. These service flows are used to pass all traffic not matching any user-defined service flow (such as broadcast ARP) between the base station and subscribers. The default service flow capacity is limited for each subscriber.

WiN5200 Product Description | 20 2.6.4 Scheduling The base station enforces QoS settings for each service flow by controlling all uplink and downlink traffic scheduling. This provides non-contention based traffic model with predictable transmission characteristics. By analyzing the total of requests of all subscribers, the base station ensures that uplink and downlink traffic conforms to the current service level agreements (SLAs). Centralized scheduling increases predictability of traffic, eliminates contention, and provides the maximum opportunity for reducing overhead. A regular period is scheduled for subscribers to register with the base station. These subscribers may be newly commissioned or have been deregistered due to service outage or interference on the wireless interface. This is the only opportunity for multiple subscribers to transmit simultaneously. Real-Time Polling Service (rt-PS) The base station schedules a continuous regular series of transmit opportunities for the subscriber to send variable size data packets. The grant size is based on the current data transfer requirement. Typical applications include streaming MPEG video or VOIP with silence suppression. This is efficient for applications that have a real-time component and continuously changing bandwidth requirements. Extended Real-Time Polling Service (ert-PS) The base station schedules a continuous series of transmit opportunities for the subscriber to send variable size data packets. This schedule supports real-time applications including VoIP with silence suppression. The dynamically scheduled grants guarantee reserved bandwidth and reduce latency introduced by repetitive grant requests. The service flow will not transmit packets larger than nominal grant interval. Non-Real-Time Polling Service (nrt-PS) The base station schedules regular transmit opportunities for the subscriber to send variable size data packets. Typical applications may include high bandwidth FTP. The polling period may typically be one second or less, even during periods of network congestion. Best Effort (BE) The base station schedules transmit opportunities for the subscriber to send traffic based on unused bandwidth after all higher level traffic scheduling requirements are serviced. Typical applications may include Internet access and email. Best effort service flows can be assigned a priority of 0 to 7. Unsolicited Grant Service (UGS) The base station schedules a continuous series of transmit opportunities for the subscriber to send fixed size data packets. This schedule supports real-time applications including VoIP or TDM transport. The UGS pre-scheduled grants guarantee reserved bandwidth and reduce latency introduced by repetitive grant requests. The service flow will not transmit packets larger than nominal grant interval.

WiN5200 Mounting | 23 3 Mounting

WiN5200 Mounting | 24 3.1 General The CPE mounting kit, which enables several mounting options such as in the following examples: 1. Poles 2. Walls When choosing the mounting location for the unit, consider the available mounting structures, antenna clearance. 3.2 Site Survey Most wireless networks include many CPEs and BSTs installed in various locations in an overlapping radio-cell pattern. It is important to position each CPE at an optimal location and the assignment of its radio channels. Therefore, a site survey becomes an essential first step before physically deploying the WiNetworks solution. Installation of the CPEs requires a backhaul to interface the corporate network or Internet. This backhaul connection can be an Ethernet-wired connection, a wireless–connection, or a third party solution. The site survey should include a detailed planning of the WiMAX system deployment. The system deployment plan should include mounting points and the routes for the power and backhaul cables. Recommended Site Requirements It is highly recommended that the WiN5200 CPEs be mounted near the edge of the roof of a tall building. The WiN5200 CPEs should be pointed in the direction of the area to be covered. To provide maximum coverage, multiple WiN5200 CPEs can be installed on the same rooftop. However, it is important to leave some distance between each unit in order to prevent interference between the units themselves. When choosing the ideal location, it is also important to take into consideration the overall area topology.

WiN5200 Equipment Configuration and Monitoring | 35 5.1 Configuring WiN5200 Basic Parameters Note The WiN5200 may be pre-configured in the lab before being sent for installation at the customer’s site. In this case, this section can be skipped. After completing the installation process, the basic parameters must be configured to ensure that the unit operates correctly and can communicate with the base station. Once the basic parameters have been configured, additional parameters can be remotely configured via the wireless link. 1. connect to the IP address 192.168.254.251 with the web browser through the Ethernet port 2. In the Login window, enter username=vendor, password=vendorpass. Figure 5-1: Login Screen 3. Check the WiN5000/5200 is configured to work in the correct frequency. To do so, choose the "CONFIG" tab and then choose showScanner. Press the "CALL" button. The command lists the channels (frequency and bandwidth pairs) the WiN5000/5200s scan in order to communicate with the base station. The channel values are set at the factory. Figure 5-2: showScanner screen

WiN5200 Equipment Configuration and Monitoring | 36 4. Use the removeChannelFromScanner command to remove a channel from the scanning procedure. In the id field, enter the ID of the scanned channel (the IDs are shown in the results of the showScanner operation). Figure 5-3: removeChannelfromScanner screen 5. To add a channel for scanning purposes, select the addChannelToScanner command. Figure 5-4: addChannelToScanner screen Enter the bandwidth and the frequency. An ID will be allocated automatically. Note The frequency and bandwidth should match the cBST configuration 6. To display physical statistics on the downlink, choose "SS" tab, from the menu on the left hand side of the screen, choose showSsPhyStatDl. Press the "CALL" button. Check the SS RSSI and CINR levels. Hit the "CALL" button to refresh the screen. Figure 5-5: showSsPhyStatDl screen

WiN5200 Equipment Configuration and Monitoring | 37 Note This field is only valid when the CPE is synchronized with the cBST. 7. Choose the "SS" tab, from the menu on the left hand side of the screen, choose showSs. Press the "CALL" button. Check if the WiN5000/5200 is in OPERATIONAL status. "OPERATIONAL" status means that the link is up. Figure 5-6: showSsPhyStatDl screen 8. Check that all the Service flows are created by using the showSF menu 5.2 Aligning the CPE Antenna The LINK QUALITY bar display is located on the bottom panel of the outdoor unit. The LED marked WLNK indicates that the wireless link is active, and is lit when the CPE has completed the Network Entry process. There are 8 LEDs that indicate the quality of the received signal. The higher the number of LEDs that are on, the better the quality of the received signal. This section describes how to align the CPE antenna using the LINK QUALITY bar display.

WiN5200 Equipment Configuration and Monitoring | 38 5.2.1 CPE Antenna Alignment Procedure • Point the antenna towards the general direction of the Base Station. • Verify that the power indication of the unit is on. • Verify that at least one green LED of the LINK QUALITY bar display is on, indicating that the unit is synchronized with the base station. If the CPE is not synchronized with the base station, ensure that all parameters are configured properly. If the CPE is still not synchronized with the base station, improve the quality of the link by changing the direction of the antenna or by placing the CPE at a higher or alternate location. • Rotate the CPE until the maximum Link Quality reading is achieved. If you encounter prolonged difficulty in achieving the expected link quality, try to improve the reception quality by placing the CPE at a higher point or in an alternate location. Note Ensure that the front of the antenna is always facing the Base Station. However, in certain conditions, such as when the line of sight to the Base Station is hampered, better reception may be achieved using a reflected signal. In this case, the antenna is not necessarily directed toward the Base Station • Secure the CPE firmly to the pole. Note In some cases, the antenna may need to be tilted to ensure that the level at which the CPE receives transmissions from the Base Station (and vice versa) is not too high. When all LINK QUALITY LEDS are on. This indicates that the received signal level is too high (saturation). This must be avoided, preferably by up-tilting the antenna. As a rule of thumb, if the CPE is located at a distance of less than 300 meters from the Base Station, it is recommended to up-tilt the antenna by approximately 10° to 15° Table 3: LINK QUALITY Bar LEDs Functionality Bar LEDs SNR WLNK is On CPE is connected with and receives services from Base station (Network Entry completed) One bar LED is On (Least significant) 5dB ≤ SNR < 10dB Two bar LEDs are On 10dB ≤ SNR < 15dB Three bar LEDs are On 15dB ≤ SNR < 20dB Four bar LEDs are On 20dB ≤ SNR < 24dB Five bar LEDs are On SNR ≥ 24dB and RSSI < -75dBm

WiN5200 Equipment Configuration and Monitoring | 39 Bar LEDs SNR Six bar LEDs are On SNR ≥ 24dB and RSSI ≥ -75dBm Seven bar LEDs are On SNR ≥ 24dB and RSSI ≥ -70dBm Eight bar LEDs are On SNR ≥ 24dB and RSSI ≥ -60dBm Only the 8th LED is On (Most significant) RSSI ≥ -20dBm (saturation) Figure 5-7:Example of RSSI Scan behavior 5.2.2 Link Indication Another function of this LED is to indicate whether or not the SS have a link with the BS. Blink - the link is down. Constant light – the link is up.

WiN5200 Management | 40 6 Management

WiN5200 Management | 41 6.1 General The CPEs can be monitored and controlled with a standalone PC or through a management system (WiNMS) using the backhaul interface. The monitoring and control capabilities are similar in both cases but the interface may appear different. This section will detail all the monitoring and control capabilities and then will specify which of them are available through each type of interface. The local PC can connect to the internal WEB server using HTTP. The CPEs have a standard MIB II and propriety MIB. Management of the CPE device shall use SNMP. All levels of management are secured by passwords. There are no local displays on the CPEs. All the indications will have to be monitored via the management system (WiNMS). 6.2 SW Download/Upgrade Software can be loaded into the CPE in several ways: • Using a local PC (connected to the nearby switch) • Remotely using SNMP (over the backhaul interface) • Remotely using FTP The CPE supports a complete rollback option in case the upgrade does not work.
