• Protection Mode
This is a mechanism to let 802.11g devices know when they should use
modulation techniques to communicate with another 802.11b device,
especially in wireless networks where there is a mixed environment that
has 802.11g and 802.11b clients (and the clients are hidden from each
other. The protection mode options include the following:
– None
This assumes there are no wireless stations using 802.11b (11 Mbps)
technology. If operating in a mixed 802.11b/g network with minimal
802.11b traffic, choose this option to ensure the best performance for
your 802.11g stations.
– Always
Protects 802.11b traffic from colliding with 802.11g traffic. This
mode is not recommended, especially if only a few wireless stations
are operating with 802.11b. Only use this mode in environments
with heavy 802.11b traffic or where there is interference.
– Auto
This is the default mode and will enable protection for 802.11g
stations if your Access/One Network finds an 802.11b client. In this
mode, if the 802.11b client leaves the network the protection mode
will revert to None automatically.
• Protection Rate
Sets the data rate at which the RTS-CTS (Request-to-Send and Clear-to-
Send) packets are sent (either 1 Mbps, 2 Mbps, 5.5 Mbps, or 11 Mbps).
The 11 Mbps data rate is the default.
