I am installing a ePMP F425 0.8 mile link which is backhauked by another F425 link. Both radios will be on the same rooftop in a rural area 55 feet apart with 70 degrees separating the azimuths. The existing radio (radio 1) is in UNII-3 at 80 MHz with a center frequency of 5775. There is a loud Cisco WiFi indoor AP in the UNII-1 band (auto-selected) at 40 MHz and heard at -40 on the rooftop. The new F425 (radio 2) will also be at 80 MHz, and I was planning on putting it in the UNII-1 band centered at 5210. Two things going for me are the short distances and there will be nothing else in the 5 GHz spectrum at this site. The other end of radio 2 is in a semi-rural area but I have not had an opprtunity yet to look at the spectrum there. I’m trying to avoid putting the Cisco AP in a 20 MHz band or reducing the power level as there may not be an appetite for that. (It’s political). I prefer to hard set the frequency on the Cisco AP because I think it will not consider congestion on the F425 radios when it auto-selects a channel. I also want to avoid using DFS channels if possible. So I guess the real question is does the F425’s high spectral efficiency have the ability to deal with this when putting the Cisco AP in the mix? To make room on the UNII 1&3 bands for all three devices, I can always use a 40 MHz channel on radio 2 thus cutting bandwidth by ~half. I will do that if I need to. Stability is more important than bandwidth here.
Any feedback will be greatly appreciated!
