I realize there will be collisions, but how determental is it to performance if part of the coverage area overlaps on the same channel?</P><P></P><P>Thank you</P> Mon, 05 Jul 2021 06:20:36 GMT https://community.cisco.com/t5/wireless/channel-overlap/m-p/17876#M195411 Steve Dussault 2021-07-05T06:20:36Z Re: Channel Overlap https://community.cisco.com/t5/wireless/channel-overlap/m-p/17877#M195412 <HTML><HEAD></HEAD><BODY><P>Signals on the same channel (no matter what the origin) will look like noise to the AP and client.
