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 are deassociated during the 6 to 8 seconds needed for the carrier busy test.

Follow 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 Radio0-802.11Gor 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.
