Query About Co-Ex Value Reliability for Channel Selection in SAS Deployments

Hi,

I’m using SAS for deploying radios and have been relying on the Google Co-Ex value for channel selection. Recently, during one of my deployments, I noticed that the Co-Ex values for some channels were marked as 0. Initially, we avoided those channels based on this value, but found that channels with higher Co-Ex values performed worse.

Eventually, we switched to using channels with a Co-Ex value of 0, and surprisingly, their performance was significantly better.

This has made me question the reliability of Co-Ex values for channel selection. Could you clarify:

  1. How reliable are Co-Ex values for making channel selection decisions?
  2. What exact method or heuristics are used to calculate the Co-Ex value?

Your insights would be greatly appreciated.

Best regards,
Saurabh
