I thought Cambium recommendation for adjacent ePMP3000 sectors was 5 MHz guard band. No guard band for PMP450.

I have a tower with a west EPMP3000 sector, and a South EPMP2000 Sector, both on Cambium antennas, and both with the BSA. They are on Adjacent, but non-overlapping channels. I have an SM that is installed at 225 Degrees into the tower, so evenly split between the 2 sectors. It see both AP's at the same signal level of -64, but Throughput tests on the SM are yielding ~5mb/1mb no matter which AP it's connected to. Other SM's which can see one of the AP's much better than the other can get 100mbs+ on the RF. The Front/back settings are for 180 opposite AP's, are there special settings for adjacent AP's? Unfortunately the SM is installed at a new construction without full time power yet, so I can't run testing on it easily, so I thought I'd ask before trying to fly blind when the customer plugs the SM in and expects a connection. I think my options are add another EPMP3000 with the Horn antenna facing the customer, or change them out to a PTP F425. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
