Radio Interface
Radio Channel – The radio channel that the access point uses to
communicate with wireless clients. When multiple access points
are deployed in the same area, set the channel on neighboring
access points at least four channels apart to avoid interference
with each other. For example, in the United States you can
deploy up to four access points in the same area (e.g., channels
36, 56, 149, 165). Also note that the channel for wireless
clients is automatically set to the same as that used by the
access point to which it is linked. (Default: Channel 60 for
normal mode, and channel 42 for Turbo mode)
Antenna ID – Selects the antenna to be used by the access
point; either the included diversity antennas or an optional
external antenna. The optional external antennas that are
certified for use with the access point are listed in the
drop-down menu. Selecting the correct antenna ID ensures that
the access point's radio transmissions are within regulatory
power limits for the country of operation. (Default: 3Com
Integrated Antenna)
Output Antenna – Selects the use of both fixed antennas operating in diversity
mode or a single antenna. (Default: Diversity)
Both: The radio uses both antennas in a diversity system. Select this method
when the Antenna ID is set to "3Com Integrated Antenna" to use the access
point's integrated antennas.
Right: To activate the 5 GHz external antenna, one must select the "right "
antenna in the antenna selection UI.
Left: To activate the 2.4 GHz external antenna, one must select the "left "
antenna in the antenna selection UI.
Transmit Power – Adjusts the power of the radio signals transmitted from the
access point. The higher the transmission power, the farther the transmission
range. Power selection is not just a trade off between coverage area and
maximum supported clients. You also have to ensure that high-power signals do
not interfere with the operation of other radio devices in the service area.
(Options: 100%, 50%, 25%, 12%, minimum; Default: 100%)

NOTE: The Antenna ID must be selected in conjunction with the Output Antenna
to configure proper use of any of the antenna options.
