We have approx 500 AP-125s and AP-105s, about 50 of which are in a 12-story residence hall on campus. Since this is tallest building in the area, there are quite a few cell antennas as well as some APs from a commercial wifi ISP. Said ISP contacted us this morning reporting a lot of (customer affecting) interference from our equipment on the 5.8GHz band they use. We temporarily disabled the a radios in the building, and this resolved the issue for the ISP.
What options are available for some sort of shielding between the ISP's APs and our Aruba APs? Of course, it would be cost-prohibitive to cover the roof in copper, but would individual copper pans pans placed either above our APs, or below the ISP's APs gain us anything (think of something like the metal disks that keep squirrels off of bird feeders)?
What else should we be thinking about? Thanks!
