B. IEEE 802.11b Direct Sequence Channels
The IEEE 802.11b standard specifies 14 Channels within the 2.4 GHz frequency band.
The following table lists the center frequency for each Channel.
If operating multiple Access Points in the same vicinity, the distance between the center
frequencies must be at least 25 MHz to avoid interference. There are three independent
Channels that do not overlap: 1, 6, and 11.
Note that the available Channels differ from country to country and based on Model
number. In the United States, Channels 1 through 11 are available.
