IEEE 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM), a

new encoding scheme that offers certain benefits over a spread spectrum in

channel availability and data rate. The 802.11a uses OFDM to define a total of 8

non-overlapping 200 MHz channels across the 2 lower bands; each of these is

divided into 52 subcarriers and each carrier is approximately 300 KHz wide. By

comparison, 802.11b uses only 3 non-overlapping channels.
