Airwave Daily RF Health Report question

In the report there is a section labled "Most MAC/Phy Errors (5 GHz)".  If see below I have a couple of iap-315's that are getting a high percentage of PHY Errors.  I would like to know what that truly is and what might be causing them.

Re: Airwave Daily RF Health Report question

It looks like the RF utilization is 43% with only a single client, which means the "energy" is being supplied by external interference, like cochannel interference, or interference from devices physically near to that device.  If it is in a server room, you would expect that non-wifi interference to be from equipment, hence your mac/phy errors.

Re: Airwave Daily RF Health Report question

Thanks.  I have moved the AP out of the server room.  I will watch it and see if that helps.
