The 802. 11a is another standard that uses the 5GHz radio spectrum, so it has 8 channels available instead of only 3 that ' s available with 802. 11b. The ' A ' version also permits a larger transfer, at a maximum of 54Mbps.

The other standard, 802. 11g, is a hybrid of ' A ' and ' B ' - - its also capable of 54Mbps but it uses the 2. 4 GHz spectrum and is compatible with 802. 11b devices.
