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.
