802.11b:
The 802.11b will accommodate legacy system and support 1, 2, 5.5 and 11Mbps data rate.
y
802.11g:
The 802.11g support data rates up to 54Mbps (6, 9, 12, 18, 24, 36, 48, 54Mbps) at 2.4GHz
frequency band by using the 802.11a OFDM techniques. This mode limits use to those WLANs
that have only 802.11g clients.
y
802.11b/g Mixed
The 802.11b/g Mixed allows you to use both 802.11b and 802.11g clients. At this mode, all
transmissions will be at the highest data rates available if the environment is with only 802.11g
devices. However, if an 802.11b device links to this network, the header information needs to
back down to 802.11b rates for all of 802.11g and 802.11b devices. It will little slow down the
network throughput. The side effect is an overall increase in overhead, so a small price is paid in
802.b/g Mixed mode.
If you make sure all of WLAN devices are 802.11g clients, then you can chooses 802.11g mode to
gain a higher performance.
y
802.11g Super
The 802.11g Super mode can support data rate up to 108Mbps (72, 96, 108 Mbps). Although you
can gain a highest data rate, you need to use this function carefully because it occupies large
bandwidth and may corrupt the adjacent channels’ radio signal.
Note:
Super G’s channel bonding feature can significantly degrade the performance of
neighboring 2.4GHz WLANs. Moreover, Super G doesn’t check to see if 11b or 11g
standard-compliant devices are in range before using its non-standard techniques.
