Base Station Units The ASWipLL Base Station interfaces between the subscriber sites and the service provider's backbone, providing subscribers with high-speed data, Internet, and VoIP services. The ASWipLL system provides various devices (some optional) for the Base Station site. The implementation of these devices depends on the desired network (e.g.
Hardw are Installation Guide O ve r vi ew 1.3.1. Base Station Radio (BSR) The BSR is an outdoor radio unit, typically mounted on a pole or wall, involved in providing a wireless link between the Base Station and subscribers. The standard BSR provides 60-degree radio coverage, serving up to 126 subscribers in a sector. For Base Stations consisting of multiple BSRs, the BSRs are powered, and interface with the provider's backbone by the ASWipLL Base Station Distribution Unit (BSDU).
O ve r vi ew Hardw are Installation Guide 1.3.3. Base Station Distribution Unit (BSDU) The BSDU is an Ethernet switch implemented at Base Stations consisting of multiple BSRs. The BSDU provides 100Base-T interface between the BSRs and the provider's backbone. The BSDU is also responsible for providing BSRs with –48 VDC power supply and frequency hop synchronization between BSDUs, BSRs, and Base Stations (when a GPS is implemented).
Hardw are Installation Guide O ve r vi ew 1.3.6. Base Station Power Supply (BSPS) - Optional The BSPS is an optional third-party unit that is implemented at Base Stations to provide –48 VDC power supply and power redundancy. The BSPS is installed in a standard 19-inch cabinet and connected to the BSDU. The BSPS provides the BSDUs and BSRs with the following: Power supply of –48 VDC. Power redundancy in case of power failure.
O ve r vi ew Hardw are Installation Guide 1.4. Subscriber Site Units The ASWipLL subscriber units are located at the subscriber's premises. The ASWipLL subscriber site consists of a radio transceiver that receives and transmits signals from and to the Base Station. The radio transceiver provides the subscriber with high-speed data access, Internet access, and VoIP at up to 4 Mbps.
Hardw are Installation Guide O ve r vi ew The SPR is mounted outside on an external wall or on a pole. The SPR connects to the SDA by a standard CAT-5 cable. 1.4.1.2. Subscriber Data Adapter (SDA) The SDA is a switch or hub (depending on model), providing the SPR with -48 VDC power supply, lightening protection, and 10/100BaseT interface to the subscriber's PCs/network. The SDA is installed indoors and can be mounted on a wall or simply placed on a desktop.
O ve r vi ew Hardw are Installation Guide SDA-4S: integrated LAN switch, providing four 10/100BaseT interfaces with the subscriber's PCs/network. The ports of the SDA-4S models support Auto Negotiation, allowing automatic configuration for the highest possible speed link: 10BaseT or 100BaseT, and Full Duplex or Half Duplex mode. In other words, the speed of the connected device (e.g. a PC) determines the speed at which packets are transmitted through the SDA-4S port.
Hardw are Installation Guide O ve r vi ew SDA-4S/1H3L: provides a high priority port (left-most port) for VoIP traffic. SDA-4S/VL/1H3L: combines the functionality of the SDA-4S/VL and SDA-4S/1H3L models (i.e. VLAN for each port and a high priority port for VoIP).

Warning: Never install equipment that is damaged. Warning: Only qualified personnel should be allowed to install, replace, and service the ASWipLL equipment. 02030311-08 Airspan Networks Inc.
Safety Guidelines Hardw are Installation Guide 2.1. ASWipLL Radios and Third-Party External Antennas Warning: Do not connect and disconnect antennas while the power is on. This can cause irreversible damage to the device. Warning: The digital portion of the transceiver has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
Hardw are Installation Guide Safety Guidelines Warning: For unlicensed bands, it is the responsibility of the person installing the ASWipLL system to ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), that only those antennas certified with the product are used. The use of any antenna other than those certified with the product is expressly forbidden in accordance with FCC rules CFR47 part 15.204.
Safety Guidelines Hardw are Installation Guide Warning: To avoid RF interference between BSRs, ensure a minimum 1-meter horizontal separation between co-located BSRs. Warning: To avoid RF interference between BSRs operating in the 700 MHz where four BSRs are installed at a Base Station, in addition to 1-meter horizontal separation, a minimum 1-meter vertical separation must be provided between the two pairs of BSR antennas: one pair operating in the lower frequencies (i.e. 711.5 and 714.
Hardw are Installation Guide Safety Guidelines 2.2. Electrical Safety Guidelines Warning: Connect the power only after all network and antenna cable connections are performed. Powering the device before connecting, for example, the external antenna, can lead to irreversible device damage. Warning: To prevent short-circuiting and electrical shocks, cables with exposed ends (i.e. not yet crimped) should be covered with protective polythene bags during external cable installation processes. 2.2.1.
Safety Guidelines Hardw are Installation Guide shall have a 2 Meg Ohm resistor fitted at either end. Wrist straps should be worn in direct contact with bare skin and not over clothing. 2.2.2. Grounding Only certain ASWipLL devices require additional grounding. ASWipLL devices that do not require additional grounding provide grounding at the main supply outlet. The following table lists the ASWipLL devices' grounding requirements.
Hardw are Installation Guide Safety Guidelines designed with transient voltage suppressor (TVS) components that maintain potential differences. However, in geographical areas that have above normal lightning activity, Airspan can supply an optional DC surge protector adapter (see Part II, Chapter 18, "Power Cabling"). 2.3. Cabling Warning: The maximum cable length between the radio transmitters (i.e. BSR and SPR) and terminating equipment is 100 meters. Warning: Cables with exposed ends (i.e.
Safety Guidelines Hardw are Installation Guide Data cables of less than 20 pairs shall be mixed in bundles not exceeding 50 mm in diameter. Ensure cables are not trapped in cabinet doors, by slide-in equipment or support metalwork. Excessive stress on cable terminations caused by taught cables should be avoided. Connector strain relief, if not built into the connector used, shall be provided by means of a strategically located cable tie.
Hardw are Installation Guide Safety Guidelines 2.3.2. Labeling The following labels are required to be fitted to ASWipLL equipment: Voltage Warning High Earth Leakage Current Signal Cable Designation 2.3.2.1.

WARNING HIGH LEAKAGE CURRENT Earth connection essential Before connecting supply Figure 2-1: Warning label if earth leakage current exceeds 3.5 mA 2.3.2.3.
5 Radio Site Planning Proper site selection and planning before installing your ASWipLL devices will ensure a successful deployment of your ASWipLL system. Site planning includes the following considerations: Minimum obstructions (e.g. buildings) in the radio path between Base Station radio (i.e. BSR) and subscriber radios (i.e. SPR/IDR). Minimum incursions on Fresnel Zone (recommended minimum of 60% clearance of first Fresnel Zone).
Radio Site Planning Hardw are Installation Guide 5.1. Minimal Radio Path Obstructions ASWipLL radios communicate by propagation of waves. Thus, ensure minimum obstructions (from, e.g. buildings and trees) in the radio path between Base Station radio (i.e. BSR) and subscriber radios (i.e. SPR/IDR). It is essential that the ASWipLL radios or antennas be installed in such a way that their radio paths have a clear path with each other. 5.2.
Hardw are Installation Guide Radio Site Planning between two antennas. Thus, the zone affects objects to the side of the path and those directly in the path. The first Fresnel Zone is the surface containing every point for which the distance from the transmitter to any reflection point on the surface point and then onto the receiver is one-half wavelength longer than the direct signal path. One method for clearing the Fresnel Zone (to use the free space model to calculate link budget – see Section 5.
Radio Site Planning Hardw are Installation Guide Figure 5-2: Radios mounted at rear, blocking multipath reflection 5.4. Spectrum Analysis for Locating Clear Frequencies Before setting up your wireless link between Base Station and subscribers, Airspan recommends (especially in unlicensed bands), analyzing the RF spectrum at the Base Station to select only clear frequency channels (i.e. without interferences) for building a frequency table for wireless communication between Base Station and subscriber.
Hardw are Installation Guide Radio Site Planning 5.5. Adjacent Base Station Radios For installations involving co-location of BSRs, it is important to assign frequencies of maximum spacing. This is to reduce possible radio interference between adjacently installed BSRs. In addition, a 1-meter separation must exist between adjacent BSRs. 5.6.
Radio Site Planning Hardw are Installation Guide The Rx value must be higher than the receiver sensitivity for communication link to succeed. Example: Frequency =2.4 GHz; Tx power output = 27 dBm; Tx and Rx cable loss = 0 dB; Tx antenna gain = 11 dBi; Rx antenna gain = 15 dBi; distance between sites = 6 km; Receiver sensitivity = -75 dBm. Transmit output power 27 dBm Cable loss (negative value) 0 dB Antenna gain 11 dBi Propagation Free space loss (negative value) 32.
Hardw are Installation Guide Radio Site Planning (RSS) to determine the signal strength received from the BSR, and to precisely align the SPR/IDR for maximum signal strength. You need to orientate (up/down, left/right) the SPR/IDR until the maximum RSSI levels are achieved, and then secure the SPR/IDR. For short links you can expect an RSSI of –60 dBm or better. For longer links, an RSSI of –75 dBm is acceptable. Any RSSI of less than –80 dBm may be too weak for the radios to reliably communicate.
Radio Site Planning Hardw are Installation Guide is the loss of radio transmit (Tx) power as heat, and directly proportional to cable length and quality, and operating frequency. 5-8 Airspan Networks Inc.
Hardw are Installation Guide Radio Site Planning To adhere to Effective Isotropic Radiated Power (EIRP) limitations in the regulatory domain (country) in which you are operating your ASWipLL system, when purchasing antenna cables, take into consideration cable loss per cable length. EIRP is calculated using cable loss (i.e. EIRP = max. transmitter power output + antenna gain - cable loss).
Radio Site Planning Hardw are Installation Guide 5.8.2. Omni-Directional Antennas In some scenarios, where capacity demand is relatively low, external omnidirectional antenna use at the Base Station may seem attractive. However, it is recommended to avoid using omni-directional antennas (if possible), due to the following disadvantages that these antennas pose compared to directional antennas: Higher sensitivity to external interferences.
Hardw are Installation Guide Radio Site Planning 5.8.4. Operating in Band-C for FCC Markets Some operators (e.g. in the USA) have licenses for Band-C (710 – 716 MHz and 740 – 746 MHz). ASWipLL 700 provides an external antenna, allowing coverage in the entire 700 MHz band (698 to 746 MHz), including the licensed A and B bands used in USA. A maximum of four BSRs operating in Band-C are allowed at a Base Station (in accordance with FCC regulations).
Radio Site Planning Hardw are Installation Guide 5.8.5. Dual Antenna Receive Diversity For BSRs operating in the 700 MHz or 900 MHz bands, two antennas are provided for antenna receive diversity at the ASWipLL Base Station. This allows the BSR to select the antenna providing the best RF reception to receive the signal. In this operating band, for BSR models with integral antennas, two internal, built-in antennas are provided.
