Find The dBm Reading On Your Phone
Having an accurate measurement of signal strength in decibels (dBm) is crucial when
installing your system. Decibels accurately measure the signal strength you are receiving.
Note:
Turn off your cell phone’s WiFi to ensure you are checking the cellular connection.
The dBm reading will be refreshed every 30-60 seconds. Want faster results? Once you
have a reading, turn on airplane mode. Wait 15 seconds. Turn off airplane mode. The
