RSSI indicator

Received Signal Strength Indicator, RSSI, ( pin 5) announces the received field strength of the

signal. This signal can be used for the approximate determination of the signal level. In the
following figure is the typical voltage level as a function of the signal level. Notice that voltage

drops with a good signal level (>-25dB). This occurs when the distance of the two modems is

less than 10 meters.
