The channel center frequencies and CH ID numbers shall be as shown below.
The FCC (US), IC (Canada), and ETSI (Europe) specify operation from 2.4
GHz to 2.4835 GHz. For Japan, operation is specified as 2.471 GHz to 2.497
GHz. France allows operation from 2.4465 GHz to 2.4835 GHz, and Spain
allows operation from 2.445 GHz to 2.475 GHz. For each supported regulatory
domain, all channels marked with "Yes" shall be supported.
In a multiple cell network topology, overlapping and/or adjacent cells using
different channels can operate simultaneously without interference if the
distance between the center frequencies is at least 30 MHz. Channel 14
