What "control channels" are you referring to? WiFi doesn't have any. Perhaps you're thinking of the cell phone network, which does. Odd. My Wifi setup page has settings for - MAC address (If I want to override/spoof) - power output (I set to 75% at present) - 802.11 band (set to 2.4GHz) - bandwidth (set to 20MHz) - control channel (Auto, 1,2,3,4,5,6,7,8,9,10,11) (set to 7 at this moment)
The wifi network scanner on my phone show the signal strengths and control channels in use by the AP in range. Again the application refers to those wifi APs as having 'control channels'. https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
Articles I read on the 'net, similarly refer to setting up APs and have graphics of the setup screens with the GUI control labelled, as is mine 'control channel'.
Well, I have never heard of a control channel on Wifi. However, on 2.4 GHz, the channel you choose is actually 1 of 4 or 5, depending on which WiFi version. I also have that app and just checked. I didn't see any mention of Wifo control channel.
Control channel is base channel when bundling multiple wifi channels to get 40/80/...MHz bandwidth.
BTW, O'Reilly has several Wifi books by Matthew Gast. I have and have read all of them.
