Testing Radio Communications Quality

Testing Radio Communications Quality
You can test the radio communications quality from the Access Point to another wireless
device using the AP Manager, or from a client to another wireless device using the
RoamAbout Client Utility.

Using the Access Point Manager

The RoamAbout AP Manager provides a Link Test tool that tests the signal quality from
the Access Point to a client or another Access Point.
1. Select the Access Point from the Managed List field in the AP Manager main window.
2. Click Integrity in the menu bar.
3. Select Link Test.
4. Under Remote Station Info in the Link Test window, click the down arrow to list the
available clients in the wireless network or the remote Access Points in a LAN-to-LAN
configuration.
5. Choose the client or Access Point to test the signal quality, then click the Start
Sampling button to start the test. To stop the test, click the Stop Sampling button.
6. Check the signal level and noise level if the SNR is low between the Access Point and
the other wireless device.
If the signal level is low, the devices may be too far apart or there are obstructions
between them. If possible, remove the obstructions, move the devices closer, or use the
optional Range Extender antenna described on page 1-15.
If the noise level is high, you may have one or more devices emitting radio signals in
the same frequency band as the client. Determine the source of interference by
selecting other clients. If available, use the RoamAbout Client Utility Link Test tool at
a mobile client to determine the extent of the noise. The source of the noise may be
closest to the device that has the highest noise level. Try to eliminate or move the
source of the noise.
