Site Survey Mode
The Site Survey test gives you an indication of the electromagnetic environment. It can also be used prior to final installation in order to determine the best location for the equipment and antennas.
During the Site Survey test, the 2.048Mbps Wireless Modem does not transmit, and a link cannot be established. Only one unit is required for Site Survey. The Site Survey graph presents the history of the received signal’s strength on each of the frequency channels (only channels included in the selected hopping set are monitored), and it performs a function similar to a spectrum analyser (Received Interference Level Spectrum Analysis). Based on the results, you can search for better location or try to identify and remove the source of the
