Command Usage
• The available channel settings are limited by local regulations, which
determine the number of channels that are available.
• When multiple access points are deployed in the same area, be sure to
choose a channel separated by at least two channels for 802.11a to avoid
having the channels interfere with each other, and at least five channels
for 802.11b/g. You can deploy up to four access points in the same area
for 802.11a and three access points for 802.11b/g.
• For most wireless adapters, the channel for wireless clients is automatically
set to the same as that used by the access point to which it is linked.
Example

This command adjusts the power of the radio signals transmitted from the access
point.

Command Usage
• The “min” keyword indicates minimum power.
• The longer the transmission distance, the higher the transmission power
required. But to support the maximum number of users in an area, you
must keep the power as low as possible. Power selection is not just a trade
off between coverage area and maximum supported clients. You also have
to ensure that high strength signals do not interfere with the operation of
other radio devices in your area.
