These limits are designed to provide reasonable protection against interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and if not installed, and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures: This equipment has been certified to comply with the limits for a class B computing device, pursuant to FCC Rules. In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception. The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user's authority to operate this equipment. Maximum Permissible Exposure In order to meet the FCC’s requirement of 1 mW/cm2 for Maximum Permissible Exposure (MPE) at 5.8 GHz, the SkyGateway/SkyExtender units must be located a minimum of 1 meter (39.4 inches) from all persons. This distance is determined based upon the aforementioned 1 mW/cm2 limit, measured data, and the far-field peak power density equation below: ()()[]SdGP 20/10282.0 += where: d = MPE distance in cm P = Power in dBm (peak) G = Antenna Gain in dBi S = Power Density Limit in mW/cm2 (1 mW/cm2) Certified laboratory measurements indicate that the FCC’s Power Density Limit of 1 mW/cm2 is met at a distance of 39 cm (15.4 inches). However a distance of 1 meter is recommended in order to introduce a margin of safety equivalent to 6.6 times the FCC’s Power Density Limit. This margin of safety compensates for the assumption of a point source antenna in the far-field equation. 1301 Shoreway Road, Suite 211Belmont, CA 94002-4106Phone 650-413-8000email: support@skypilot.comWeb: www.skypilot.com

SkyGateway/SkyExtender Installation And Configuration September 2004 1-1 C HAPTER 1 I NTRODUCTION A SkyPilot System is made up of the following components: SkyGateWay . This network element provides an interface between the network and the Internet or WAN via a 10/100BASE-T connector. A minimum of one SkyGateway unit is required for a SkyPilot System; additional units provide redundancy in case of a power failure or other problem at the main gateway. SkyExtender . These nodes connect directly to a SkyGateway device, to other SkyExtender nodes, and to SkyConnector Indoor and SkyConnector Outdoor subscriber units. They provide the framework of the network. A SkyExtender is typically installed on a roof, tower, light or utility pole, or other fixed location. In a rooftop installation, a 10/100BASE-T Ethernet connection is available for subscriber usage. SkyConnector Indoor and SkyConnector Outdoor . These units are installed in subscribers’ homes or offices. A SkyConnector provides an interface between the subscriber’s computer and the network. The interface between the SkyConnector and the network is via a wireless connection to a SkyExtender. The interface to the subscriber’s computer is via an Ethernet cable. The outdoor unit typically provides greater range than the indoor unit and is normally installed on an eave or roof. The indoor unit is installed on a windowsill or in a window frame by the subscriber without a truck roll and offers simple plug-and-play configuration.This manual provides instructions for installing and maintaining SkyGateWays and Sky Extenders. See the SkyConnector Indoor Unit and SkyConnector Outdoor Unit Installation Guides for information about those products.
SkyGateway/SkyExtender Installation And Configuration Guide 1-2 September 2004 System Overview SkyGateWay basestations and SkyExtender nodes form the backbone of a SkyPilot System. Both devices feature:•A compact, lightweight design that permits easy installation in a wide range of loca-tions.•High-power, 360° coverage.•An efficient single connection for both power and data.SkyGateWay and SkyExtender units are virtually identical, differing only in their soft-ware. SkyGateWay basestations use a superset of the SkyExtender software that includes the necessary programming to communicate with an external network. The SkyExtender is comprised of five separate modules: baseband motherboard, mPCI radio module, switchboard, and antenna array. Physical Specifications and Installation Each SkyGateWay or SkyExtender is only 18 inches high, 12 inches in diameter, and 14 pounds in weight. The compact size and light weight mean that these units can be installed on existing structures such as utility poles, commercial buildings, homes, billboards, and water towers. Each unit comes with a mounting bracket that fits over a standard 1.25-inch-diameter pole. Operating temperatures can range from -40°C to 55°C (-40°F to 130°F). Power Because they use Power over Ethernet (PoE) and draw only about 10 watts, the only cabling these units require is CAT-5 Ethernet cable. There is no need to lease dedicated poles or run power cables, and no special tools are required for installation. Antennas The eight antennas in a basestation or node provide sectorized 360° coverage. Each antenna has a horizontal beamwidth of 45°, a vertical beamwidth of 6.5°, and a gain of 18 dBi. Modules The motherboard has a PowerPC CPU, volatile and non-volatile memory, a DC power interface, and interfaces to other system components. An mPCI radio enables a SkyGateWay or SkyExtender to transmit and receive in the 5.8GHz band using modulation rates of 6 to 54Mbps, providing a peak EIRP of 44.5 dBm (28.2W). The radio currently supports a range of center frequencies from 5745MHz-5805MHz. Each channel is 20MHz wide and can configured on 5MHz frequency granuality. Up to 4 non-
SkyGateway/SkyExtender Installation And Configuration September 2004 1-3 overlapping channels can be supported. In an environment free from significant interference in the UNII band, as many as four SkyGateWay or SkyExtender units can be installed at a single location, each configured to use a different channel.The radio module also contains the wireless MAC and Physical Layer logic, implementing the 802.11a hardware specification via an Atheros chipset. The radio module connects to the motherboard for data and to the switchboard for RF.A switchboard provides the connection between the radio and the antenna array. It provides antenna selection and amplifies the radio signal.An integrated GPS receiver in both SkyGateWay and SkyExtender basestations is used by SkyControl software to synchronize transmissions within the network. It connects directly to the motherboard. The GPS antenna is positioned on top of the antenna array assembly inside the SkyGateWay enclosure. Connectors A RJ-45 jack enables a SkyGateWay to receive power and connect to an external network. The same jack on the SkyExtender is normally only used for power, but can also be used to connect directly to a subscriber’s network or computer. (Both units come with a Power over Ethernet injector module that combines incoming data and power onto one Ethernet jack that connects to the SkyGateWay or SkyExtender device.)An optional serial adapter (RJ-45 connector) permits local access to a command-line interface (CLI) to change the unit’s settings.
SkyGateway/SkyExtender Installation And Configuration Guide 1-4 September 2004 Network Architecture The SkyPilot system software manages communications protocols at all levels, from RF to routing. It carefully manages SkyGateWay, SkyExtender, and subscriber nodes to create the best possible network performance.SkyProvision software is used to configure the system.The SkyPilot System operates as a Layer 2 network. All subscriber traffic goes to and from the network via an external switch or router attached to the Ethernet bridge in a SkyGateWay basestation. Peer-to-peer communication is not permitted within a SkyPilot System. Physical and Link Layers Physical Layer . At the RF layer, the components of a SkyPilot System use standard 802.11a modulation operating in the 5.8GHz range. The Physical Layer SkyPilot protocol conforms to the 802.11a specifications with the addition of a synchronous one-second frame. The timing of this frame is derived from a GPS receiver in each SkyGateWay and SkyExtender. The frame’s signal is used to control transmission and reception in the network, and also provides a reference for the “hello message” exchange (a beacon/response sequence that allows nodes and gateways to establish connections). Data Link (MAC) Layer . At the MAC layer, SkyPilot implements a synchronization protocol that takes advantage of the one-second RF frame to establish links and exchange secure, rate-controlled data between devices. Routing Above the MAC layer, SkyControl brings into play a dynamic routing protocol that ensures the most efficient utilization of network resources and provides for rapid rerouting around link and device failures. SkyControl allows SkyExtender nodes and SkyConnector subscriber units to join the network automatically.When a SkyExtender node connects to the network, it selects an optimum route to a SkyGateWay. The route selection considers link capacity (modulation rate), and the number of hops between the node and the gateway. Once a route is selected, all user traffic is forwarded via this path unless conditions change. Rerouting is necessary (and automatic) when a link or node is lost. The SkyPilot system also automatically reroutes traffic when it determines that a lower cost route is consistently available. (A connection’s “cost” is determined by the number of hops it requires and the modulation rates on each of the connection’s component links.)
SkyGateway/SkyExtender Installation And Configuration September 2004 1-5 Scheduling and Bandwidth Management As mentioned, the SkyPilot System supplements the 802.11 protocol with sophisticated synchronization. By transmitting over different antennas in different 100us mini-slots of the one-second synchronization frame, a SkyPilot basestation or node provides 360° coverage through multiple high-power point-to-point connections. In addition, highly accurate traffic rate control and jitter control are enabled.Bandwidth management within a network presents a particular challenge due to the high number of interconnections, with each SkyExtender node typically communicating with a multitude of others. The SkyPilot system ensures that mini-slots are provided over each link, with the number of mini-slots used by each pair of nodes varying as subscriber bandwidth demand changes.The SkyPilot system provides rate control for subscriber traffic both in the downstream (SkyGateWay to SkyConnector) and upstream (SkyConnector to SkyGateWay) directions. Maximum upstream and downstream rates can be specified for each subscriber. In conditions of oversubscription, when the overall bandwidth demand is higher than system capacity, the individual subscriber data rates will be reduced proportionately.

SkyGateway/SkyExtender Installation And Configuration Guide 2-2 September 2004 Plan The Installation Site Survey In a typical wide-area wireless network utilizing SkyPilot units, the SkyGateWay is installed on the roof of a tall building or tower. The direct coverage area of the SkyGateWay is generally proportionate to the height of the installation.A SkyGateWay may also be used in smaller scale networks. Examples include high-capacity business or academic campus interconnection, or a localized access network. In this case, the SkyGateWay could be installed on a local, medium height building or utility pole.The SkyExtender may be installed on home rooftops, tall buildings, or on light or utility poles. Refer to the Site Planning document for more information. Frequency SkyPilot recommends that an operator utilize a spectrum analyzer to scan the UNII spectrum prior to installing one or more SkyGateWays. This information will be necessary later when configuring the frequency. See the SkyPilot Network Management Guide for more information about frequency .
