11B CLIENTS, YOU PROBABLY DO NOT WANT IT TO BE BECAUSE IF YOU MUST...

802.11b clients, you probably do not want it to be because if you must support 802.11b

clients, the entire cell suffers. In fact, if the average bandwidth is 22 Mbps in an 802.11g cell

and an 802.11b client shows up, the cell performance could degrade. This degradation in

performance is because 802.11b clients do not understand OFDM. If an 802.11b client sends

when an 802.11g client is sending, a collision will occur, and both clients will have to resend.

However, protection mechanisms are built in. To understand how this protection works,

examine Figure 6-1.
