[[BR]] Seeing good throughput (up to 14Mb/s DL and 1 - 2 Mb/s UL) to 0.25 mi.[[BR]] Discovered antenna tilt was incorrect (too much); set to actual -2 deg; some iperf TCP and iperf UDP tests indicated longer range.[[BR]] Had connectivity problem; after trial and error with BTS parameters; setting odu_noise_floor to 100 fixed the connectivity problem. [[BR]] Still need to try other BTS parameter options, based on NEC suggestions.[[BR]] Currently working towards use of OMF/OML to control range and throughput experiment.[[BR]] Need to repeat range and throughput experiments using iperf TCP and iperf UDP. [[BR]] Do not expect range beyond 0.6mi.
