Running the Carrier Busy Test
Running the Carrier Busy Test
You can use the carrier busy test to determine the least conjested channel for a radio interface (802.11g
or 802.11a). You should typically run the test several times over several days to obtain the best results
and to avoid temporary activity spikes.
Note
The carrier busy test is primarily used for single access points or bridge environments. For sites with
multiple access points, a site survey is typically performed to determine the best operation location and
operating frequency for the access points.
Note
All associated clients on the selected radio will be deassociated during the 6 to 8 seconds needed for the
carrier busy test.
Perform these steps to activate the carrier busy test:
Step 1
Use your web browser to access the access point browser interface.
Step 2
Click
Network Interfaces
and the Network Interface Summary screen appears.
Step 3
Choose the radio interface experiencing problems by clicking
Radio0-802.11G
or
Radio1-802.11A
.
The respective radio status page appears.
Step 4
Click the
Carrier Busy Test
tab and the Carrier Busy Test screen appears
Step 5
Click
Start
to begin the carrier busy test.
When the test completes, the results are displayed on the screen. For each of the channel center
frequencies, the test produces a value indicating the percentage of time that the channel is busy.

provides two modes of operation:
