We have had multiple complaints from users who have experienced signal strength issues in the last week. We have since found out that when a 500 series AP broadcasts on 5GHz, within the UNII-3 band (149-161) the transmit power is limited to 14dbm. I have tested this with an AP-504 and saw a difference of 20dbm between 2.4GHz channel 11 (-47dBm) and 5GHz channel 157 (-66dBm). I was less than 5m away from the AP with no obstructions, so deployments across our campus will be suffering from this feature.
Is this restriction imposed within any other band within the 5GHz range?
Does this only affect 504/5 or the entire 500 series range of access points? Also, are any other AP series affected by similar restrictions?
Thanks, Adam
