channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending

signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the

center channel frequency. As a result, two separate wireless networks using neighboring channels

(for example, channel 1 and channel 2) in the same general vicinity will interfere with each other.

Applying two channels that allow the maximum channel separation will decrease the amount of

channel cross-talk, and provide a noticeable performance increase over networks with minimal

channel separation.

The radio frequency channels used in 802.11b/g networks are listed in Table B-2:

Note: The available channels supported by the wireless products in various countries are different.

For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are

supported in Europe and Australia.

The preferred channel separation between the channels in neighboring wireless networks is 25

MHz (5 channels). This means that you can apply up to three different channels within your

wireless network. There are only 11 usable wireless channels in the United States. It is

recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as

these three channels do not overlap.
