7.1 Cellular Signal Strength

Received Signal Strength Indicator (RSSI) is the measure of RF signal strength between the Remote Station modem and a base station, expressed in dBm. The signal strength should be no less than -100 dBm (considered weak coverage), -50 dBm is considered full signal strength.

A site survey can be performed prior to installation, to determine the signal strength on site. This can be done using a cellular device.

For STS modems, a general indication of the signal strength can be determined from the number of LEDs that light up on the modem:

Signal strength can be increased by adding an optional antenna, or by simply relocating the Remote Station to an area with maximum signal strength on site.
