11B OR 11G PRODUCTS, THE CHANNELS HAVE A BANDWIDTH OF 22 MHZ....

802.11b or 802.11g products, the channels have a bandwidth of 22 MHz. This allows three

nonoverlapping, noninterfering channels to be used in the same area.

The 2.4-GHz range uses direct sequence spread spectrum (DSSS) modulation. DSSS is dis-

cussed later in this chapter in the section “DSSS.” Data rates of 1 Mbps, 2 Mbps, 5.5 Mbps,

and 11 Mbps are defined for this range.
