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 Hardware 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.
Hardware 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. For calculating Fresnel Zone, refer to the ASWipLL System Description. 5.3.
Radio Site Planning Hardware Installation Guide 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.
Hardware Installation Guide Radio Site Planning Airspan offers various tools for measuring RSS (check with your Airspan representative regarding cost and supply): ! SPR: ! RSS LED adapter (see Part II, Chapter 17, "Antenna Alignment using RSS LED Adapter") ! WipConfig program (see Appendix E, "Evaluating Link Quality") ! IDR: built-in RSSI LEDs (see Part III, Chapter 24, " Antenna Alignment Using RSS LEDs") 5.7.
Radio Site Planning Hardware Installation Guide To adhere to EIRP limitations in the regulatory domain 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. power output + antenna gain - cable loss).
Hardware Installation Guide Radio Site Planning 5.7.2. 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.
Radio Site Planning Hardware Installation Guide 5.7.3. 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).
Part I Base Station Installation Part I describes the procedures for installing the ASWipLL devices located at the Base Station, and includes the following chapters: ! Chapter 6, “Basic Design of Devices” ! Chapter 7, “Mounting the Devices” ! Chapter 8, “Network Cabling” ! Chapter 9, “Serial Cabling” ! Chapter 10, “Connecting Third-Party External Antennas” !
