Under what circumstances will a controller lower the power level on a 5 Ghz radio? In some areas I am seeing RRM controlled power levels as low as 5.
I thought because of the greater number of available channels, the potential for co-channel interference would be reduced to the point where decreasing power would seldom be necessary. The channel width is 20Mhz, and the ap's are in the US.
It seems to be happening more frequently with the higher version of code, i.e. 7.5 and 7.6 on 5508's and wism2's. It doesn't seem to happen on older 4402 controllers running 7.0 code.
So why would a controller lower the power of a 5Ghz radio, and is there a difference in the RRM configuration in 7.0 and 7.5/7.6 version code?
Please ask questions if more information is needed to respond.
