Cell Signal Strength Metrics (RSRP. RSRQ, SINR, RSSI)

RSRP
RSRP Signal strength Description
>= -80 dBm Excellent Strong signal with maximum data speeds
-80 dBm to -90 dBm Good Strong signal with good data speeds
-90 dBm to -100 dBm Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -100, performance will drop drastically
<= -100 dBm No signal Disconnection
RSRQ
RSRQ Signal quality Description
>= -10 dB Excellent Strong signal with maximum data speeds
-10 dB to -15 dB Good Strong signal with good data speeds
-15 dB to -20 dB Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -20, performance will drop drastically
<= -20 dB No signal Disconnection
SINR
SINR Signal strength Description
>= 20 dB Excellent Strong signal with maximum data speeds
13 dB to 20 dB Good Strong signal with good data speeds
0 dB to 13 dB Fair to poor Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to 0, performance will drop drastically
<= 0 dB No signal Disconnection
RSSI for LTE is a calculated from several other signal related measurements: RSSI = wideband power = noise + serving cell power + interference power. For example, a 4G LTE modem might report an RSSI of -68 dBm, but:
RSRP = -102 dBm
RSRQ = -16 dB
SINR = -1.8 dB
In this case, the signal quality is actually very poor. This could be due to the device being some distance away from the LTE transmitter. It’s also possible that something is interfering with the signal, such as a building or other obstructions between the device and the tower.
RSSI
RSSI Signal strength Description
> -65 dBm Excellent Strong signal with maximum data speeds
-65 dBm to -75 dBm Good Strong signal with good data speeds
-75 dBm to -85 dBm Fair Fair but useful, fast and reliable data speeds may be attained, but marginal data with drop-outs is possible
-85 dBm to -95 dBm Poor Performance will drop drastically
<= -95 dBm No signal Disconnection
