To check the RSRP and RSRQ signal quality on your modem, issue the AT command
for your specific modem located in the table below:
The signal quality parameters for the QBG96 and QBG95 modems are as follows:

Parameter
Notes
<gsm_rssi>,<lte_rssi> An integer indicating the received signal strength. These
parameters are available for GSM and LTE modes,
respectively.
<lte_rsrp>
An integer indicating the reference signal received power
(RSRP). This parameter is available for LTE mode.
<lte_sinr>
An integer indicating the signal to interference plus noise
ratio (SINR). Logarithmic value of SINR. Values are in
1/5th of a dB.The range is 0-250 which translates to -20dB
-+30dB.
<lte_rsrq>
An integer indicating the reference signal received quality
(RSRQ) in dB.
