Wireless LAN channels
The IEEE 802.11b/g standard for wireless LAN allocated the 2.4 GHz
frequency band into 13 overlapping operating channels. Each channel
corresponds to a different set of frequencies. The table below shows the
center frequencies of each channel.

between the center frequencies of channels used must be at least
25MHz to avoid interference.
