Understanding LTE Signal Strength Values

3G (WCDMA, TDSCDMA, CDMA, EVDO, CDMA-EVDO)

For 3G service mode, there are three relevant measurements:

  • RSSI – Received Signal Strength Indicator. RSSI is a negative value, and the closer to 0, the stronger the signal
  • EC/IO – indicates the downlink carrier-to-interference ratio (signal quality).EC/IO is a negative dBm value. Values closer to 0 are stronger signals
  • RSCP – indicates the Received Signal Code Power

The RSSI standard values for 3G are basically the same as 2G

RSSI
RSSI Signal strength Description
>= -70 dBm Excellent Strong signal with maximum data speeds
-70 dBm to -85 dBm Good Strong signal with good data speeds
-86 dBm to -100 dBm Fair Fair but useful, fast and reliable data speeds may be attained, but marginal data with drop-outs is possible
< -100 dBm Poor Performance will drop drastically
-110 dBm No signal Disconnection
EC/IO
EC/IO Signal quality Description
0 to -6 Excellent Strong signal with maximum data speeds
-7 to -10 Good Strong signal with good data speeds
-11 to -20 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
RSCP
RSCP Signal strength Description
-60 to 0 Excellent Strong signal with maximum data speeds
-75 to -60 Good Strong signal with good data speeds
-85 to -75 Fair Fair but useful, fast and reliable data speeds may be attained
-95 to -85 Poor Marginal data with drop-outs is possible
-124 to -95 Very poor Performance will drop drastically, closer to -124 disconnects are likely

To check the 3G signal strength values of your RUT device, log in to your router’s WebUI and go to the Status -> Network -> Mobile window:

4G (LTE)

For 4G service mode, there are four relevant measurements:

  • RSSI – Received Signal Strength Indicator. RSSI is a negative value, and the closer to 0, the stronger the signal
  • RSRP – the Reference Signal Received Power is the power of the LTE Reference Signals spread over the full bandwidth and narrowband
  • RSRQ – Reference Signal Received Quality is a C/I type of measurement and it indicates the quality of the received reference signal (similar to EC/IO)
  • SINR – Signal to Interference plus Noise Ratio (A minimum of -20 dB SINR is needed to detect RSRP/RSRQ). Indicates the throughput capacity of the channel. As the name implies, SINR is the strength of the signal divided by the strength of any interference
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
