Verify modem signal strength and quality

If your modem appears to be connecting to the network, but you are unable to reach it, check the signal strength and quality in the ACE Manager web interface.

1. Log in to the ACE Manager login page with your username and password.

2. Once you are logged in, click Cellular on the left menu.

3. Check the LTE Signal Strength (RSRP) and LTE Signal Quality (RSRQ) and compare them to the following tables to determine the quality of the connection to the cellular network.

   RV50(X) series signal strength
   Signal strength	RSSI (3G)	RSRP (4G)
   Excellent	–70 dBm or greater	–90 dBm or greater
   Good	–70 dBm to –85 dBm	–90 dBm to –105 dBm
   Fair	–86 dBm to –100 dBm	-106 dBm to –115 dBm
   Poor	< –100 dBm	< –115 dBm

   RV50(X) series signal quality
   Signal quality	ECIO (3G)	RSRQ (4G)
   Excellent	0 to -6	> –9
   Good	–7 to –10	–9 to –12
   Fair to Poor	–11 to –20	–13 or less

If the signal strength and/or signal quality is poor, you may have to redirect or relocate the cellular modem antenna to a place with a better cellular signal. Upgrading the antenna or adding a diversity antenna can offer better performance.
