IEEE 802.11a Channels
The 802.11a specification today specifies 4 channels for the UNII1 band, 4 channels for the UNII@ band, and 4 channels for the UNII3 band. These
channels are spaced at 20 MHz apart and are considered non-interfering, however they do have a slight overlap in frequency spectrum. It is possible
to use adjacent channels in adjacent cell coverage, but it is recommended when possible to separate adjacent cell channels by at least 1 channel.
Figure 11 shows the channel scheme for the 802.11 bands, and table 9 lists the North American frequency allocations.
