Transmit Rate
A lower signal will increase the noise. In essence, the poorer the signal-
to-noise ratio, the lower this rate should be set.
Note: The transmit rate affects only the transmissions made by this
station.
Note: In case of 802.11b/g, the channel/frequency values are usually
determined by network administrators. If you set the channel and
frequency ensure that there are at least four numerical channels
difference between two overlapping cells to avoid interference. For
example, channels 1, 6 and 11 don't overlap, but channels 1 and 3 do.
In the other side, if you are intended to use 802.11a, please keep in mind
that all channels (4 channels) with 20MHz bandwidth are not permitted
to be overlapped with each channels in the frequency plan.
Radio Transmit Power -- Select the Transmit power in the list of five
(4) power levels as below.
Transmit Power
Maximum
50%
25%
12.5%
Note: It is recommended that you set the transmit power to "Maximum"
as the antenna listed in Appendix C (Antenna) has been designed to meet
FCC regulation to restrict the actual transmit power (EIRP) at the
maximum transmit power.
