What is considered high channel utilization?

Userlevel 1
This is on our C5210 controller, showing AP performance report by radio.
Can this tell me if an Apple TV is causing problems?

Can someone explain what these numbers mean? What is considered high channel utilization in the last column?

Typically you want to see about 50 to 60% or lower on the average column. You also want to check the amount of clients per the radio that is showing high utilization. Usually the higher the user count, the higher the channel utilization. If the utilization is consistently high but the user count is relatively low, this may be an indication of Co-Channel interference (other AP’s on the same channel) or non-802.11 interference on the band the AP is using.
