Band Plan

List of WiFi channels.

San Francisco / Oakland / Berkeley

Channel	Width (MHz)	Purpose	Notes
171	10	Cross Bay
173	20	Richmond / Berkeley / Oakland / HWD	We should probably be using 174 to avoid overlap with 171 (see here)
175	10	Mount Diablo
177	10	Oakland / Berkeley
179	10	SFWEM
181	10	NALCO
183	10	NALCO

Notes

I confess that I don't understand how a band plan should work in a wifi network when we have a combination of tight point-to-point links with beam widths of 7° (beam diameter is ~1/8 the beam distance) with sectors with beam widths of 120° (beam diameter is ... massive).

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.
