Cellular Radio Signal Level Cellular radio signal level indicates strength of the MultiSensor's cellular signal. Your sensor will indicate the cellular connection type, 3G or LTE, along with a graphical representation of the signal strength on the Radio Dashboard icon. More blue arcs indicate a stronger signal. The icon does not tell you if you have no cell service. The "Updated" status on the dashboard will display in red after the sensor fails to send two synchronous reports which occur every 20 minutes. So, after 40 minutes of no connection the status will appear red and will state "Last Report" instead of "Updated". The Signal History graph displays the levels in dBm (3G signals) or as blend of dBm and signal quality (LTE). • Levels that are between -60 and -100 are good. • Signal levels from -100 to -110 are marginal but may be acceptable. • Signal levels from -110 to -130 are poor.
