Optimizing RoamAbout Outdoor Antenna Placement
5. Check the signal level and noise level if the SNR is low between the AP and the
wireless device.
If the signal level is low, the devices may be too far apart or there are obstructions
between them.
If the noise level is high, determine the source of interference by selecting other clients.
If available, use the RoamAbout Client Utility Site Monitor tool at a mobile client to
better determine the location of the interference.
Optimizing RoamAbout Outdoor Antenna Placement
If an AP in a LAN-to-LAN configuration is connected to an outdoor directional antenna,
the antenna must be pointed directly at the antenna for the other AP. A misaligned antenna
can decrease the signal level or prevent communications.
The RoamAbout AP Manager provides a Point-to-Point diagnostic tool that can help you
adjust the directional antenna to optimize the signal between APs. If you are testing the link
between two APs that both use directional antennas, you may need one person at each
antenna and a method to communicate with those people.
1. Select the AP from the Managed List field in the AP Manager main window.
2. Click on the Integrity drop-down menu and select Link Test.
3. Under Remote Station Info in the Link Test window, click the down arrow to list the
available APs in the LAN-to-LAN configuration.
4. Choose the AP to test the signal quality then click Start Sampling to start the test.
5. To improve the signal strength, watch the SNR indicator and slowly move the antenna
in the direction that improves SNR. You may need to have a person at the remote
location move the antenna while monitoring the SNR.
6. To stop the test, click the Stop Sampling button.
NOTE: Antennas should only be installed by a qualified antenna
installer. The antenna installation professional should be licensed or
certified in accordance with local regulations.
If you are planning to use an outdoor antenna refer to the RoamAbout
Outdoor Antenna Site Preparation and Installation Guide for regulatory
information, FCC requirements, and detailed procedures to install
outdoor antennas.
