Performing some testing, we found out that turning these units on was adding more activity on the channel used. The more units were in use, the more the channel appeared to be used.
So to make sure that we have had found the interference, we unplug the Wireless Control Access Point. And the channel cleared up. We were now sure that this conferencing system was the interference detected.
So we plugged the system back on, and surprised, it started to use another channel (channel 8)!
I was not able to find more details about what the 4 bands were but I have seen the Televic system use the 2.4GHz band as well as the UNII-3 band.
How to deal with it
Here is what the documentation says:
- Configure the 3 Confidea systems to use frequencies in the 5GHz band. Each system will have to be using a different channel to avoid interference. Do not use the 2.4GHz band.
- Create a RF profile on the controller excluding the use of these 3 5GHz channels.
- Use this RF profile for the access point deployed in and around the training centre.
