I have two access points using channel 36 (40 MHz) that overlap each other. Should I set Ce on the first AP and eC on the second, or should I use Ce on both?
If I use Ce on the first and eC on the second, their beacons won't interfere. But what about data transmission? Doesn't channel access coordination happen on the primary channel? Will the second AP listen to the traffic from the first AP and decide to wait on transmitting if a transmission is already happening? Is the listening only on the primary channel or both?
If I set Ce on both, their beacons will interfere, but will this ensure that transmissions won't interfere?
Note: Ce and eC refer to different channel configurations. "Ce" means the primary channel is the first 20 MHz (in this case, channel 36) and the extension channel is above it (channel 40). "eC" means the primary channel is the second 20 MHz (channel 40) and the extension channel is below it (channel 36).
