Hi experts,
I have measured the channel utilization of one of my customers at midnight and it has an average of 25%. I have measured the same at 11 am when the people is working and has increased but not so much, just 5% in some APs. It is a cluster of 8 IAPs and they are 15 meters far each other more or less. The cluster has 4 SSIDs configured and the network has little users, no more than 30 across all the cluster.
As the channel utilization is roughly the same in working hours and at midnight, I think it is due to co-channel interference and management traffic of the own network. I have seen the Wi-Fi SSID Overhead Calculator, and looking at 4 SSIDs (column) and 2 APs on the same channel (row) which is my case, the overhead is around 25%, which matches the channel utilization I have seen in this network:
Do you this channel utilization is due to my own network? Or it could be due to interferences or foreign networks? Is there any command to verify this? Thanks in advance.
