Comments
Channels are defined to be 5 MHz wide, reaching 2.5 MHz above and below their center frequency. Most channels used by BAM are 10 MHz wide, so +/- 5MHz of their center frequency. This means we only use odd channel numbers as 10 MHz channels overlap with even channels.
20 MHz channels extend +/- 10 MHz. This mean the partially or completely overlap with two channels above and below.
We currently use channel 173 as a 20 MHz channel. We should probably be using 174 to avoid overlap with 171 which we also use (see https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax)
