•Protection Type – Click a protection type: CTS Only or RTS CTS. The
default and recommended setting is CTS Only. Click RTS CTS only if an
11b AP that operates on the same channel is detected in the
neighborhood, or if there are many 11b-only clients in the environment.
Note: The overall throughput is reduced when Protection Mode is enabled,
due to the additional overhead caused by the RTS/CTS. The overhead is
minimized by setting Protection Type to CTS Only and Protection Rate to
11 Mbps. Although, the overhead causes the overall throughput to be
sometimes lower than if just 11b mode is used. If there are many 11b clients,
it is recommended to disable 11g support (11g clients are backward
compatible with 11b APs).
An alternate approach, although a more expensive method, is to dedicate all
APs on a channel for 11b (for example, disable 11g on these APs) and disable
11b on all other APs. The difficulty with this method is that the number of APs
must be increased to ensure coverage separately for 11b and 11g clients.
