v52 v53 140 140 * See Sec 6.1 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)] fro outdoor site options, and Sec 6.6 for pole options. 141 141 * See Sec 1.2 of [http://groups.geni.net/geni/attachment/wiki/WiMAXInteg/CampusInstallation/ANTENNA.pdf NEC Sector Antenna Installation Manual], which specifies a pole diameter between 48mm and 120mm. 142 * For example, the pole may be su uported on a roof using an H bracket; see Sec 6.1 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)]142 * For example, the pole may be supported on a roof using an H bracket; see Sec 6.1 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)] 143 143 * The pole should be mounted in a position that optimizes the performance (e.g., the range) of the antenna. 144 144 * The pole must be connected to the heavy cable that runs to the building ground, for lightning protection. … … 155 155 Install the antenna following Sec 1 - 5 of the [attachment:ANTENNA.pdf NEC Sector Antenna Installation Manual] 156 156 157 Since throughput and coverage of WiMAX systems are highly influenced by the antenna location, care should be taken that the antenna is mounted so that siginificant portion of First Fresnel Zone is clear of obstructions. Ideally the antenna is mounted on the elevated structure providing clear line of sight to most of the intended coverage area. 158 159 ISSUE: All of this needs to be explained. How does its height influence the coverage? Are we limited to 6' above the structure? If so, how is this measured? On which side of the pole should the antenna be mounted? How should it be tilted? How do these influence the coverage pattern? 160 161 ISSUE: Do we also need GPS receiver and antenna, per NEC documentation? If we do not install it now, what might we be missing later? 157 Since throughput and coverage of WiMAX systems are highly influenced by the antenna location, care should be taken that the antenna is mounted so that significant portion of First Fresnel Zone is clear of obstructions.
