Hello Kool Kats: Hope you are enjoying a nice Sunday. Well I know some of you are in the clutches of ole man Winter. Did some testing with the M900 Rocket with dual pol Yagi installed at Condor's Lower Comanche Peak site Friday afternoon. The Good: Even at 8 miles blocked by buildings and houses, I could see the AP on site survey menu with signals in the -89 to -95 dBm range but no association. We had a mast with two antennas and M900 on truck with height about 10 ft. AGL. We moved to higher point and signal jumped to -75 dBm, The Bad: Radios associated but would not pass traffic using 5MHz channels. I tried 3 MHz channels as well and would not either. Noise floor was jumping from -95dBm to -81 dBm.. The association would stay up at -79 dB while moving and drop. As soon as we had clear shot with would connect but pass no traffic from Internet. I could make changes to AP but that was all. We moved closer to site and parked at furniture store with clear LOS. Even with a -65 dBm at 6 miles ,,,no Internet traffic. I had an IP from MT and speed test would load slowly and error out with latency message. Pings were all over the place with a few time outs. So interference was too great in this part of town to use these. I will share screen shots in later posts. We knew the 902.928 MHz noise floor in central and east side of El Paso was high so I was not surprised. On the far west El Paso which borders with New Mexico, we have a water company using these for SCADA and cameras at 1 1/2, 3 and 6 miles with no problems using 5 MHz channels colocated with Phoenix Contact FHSS 900MHz I/O. This link has an Ubiquiti sector on AP and dual TY-900 antennas at CPE side. Note: The M900 AP is collocated with several M5 rockets on same tower.
