AP Power Display
Select the power range image to display for a managed AP:
Disable Power Display—The power range image is not displayed
Show 802.11 a—Shows the transmit power for all managed APs that have a radio
operating in 802.11a mode.
Show 802.11 b/g—Shows the transmit power for all managed APs that have a radio
operating in 802.11 b/g mode.
The size of the power range image is based on the transmit power for the radio,
which can be low, medium, or high. The size of the power range image also
depends on the actual scale factor of the current background image.
If the AP has two radios that are configured in the same mode, two power range
images are displayed.
Note:
The color of the power range image is based on the assigned channel of
the associated radio.
If two APs use the same channel (or channels that are close together) and are
within each other’s transmission range, the APs will interfere with each other and
wireless clients will experience poor WLAN performance. To reduce interference,
you can take one of the following steps:
•
Reduce the transmit power on the APs.
•
Physically place the APs further apart.
•
Use the automatic channel adjustment algorithm on the APs or statically set the
channels so they are non-interfering channels.
Caution!
Power ranges are for illustrative purposes only. The actual power
distribution varies based on factors such as office wall propagation and background
RF noise.
