The following indicators are used to determine the quality of a 4G LTE signal.  The charts indicate rough guidelines as to what constitutes a particular level of quality, ranging from excellent to unusable. 

To avoid performance issues none of these values should be in, or dip into the red.  Optimal performance is achieved when all values are in the green.

Diagnosing Signal Issues

There are many reasons why signal performance can vary significantly, which is why it is important to accurately diagnose your signal issues so that the correct solution can be implemented.  For more information on how to diagnose signal issues see our Guide to Understanding Poor Mobile Coverage, which contains advice that applies to mobile phones and mobile data devices.

 

RSRP - Reference Signal Received Power

RSRP Quality Description
≥ -80 dBm Excellent Strong signal enabling maximum data capacity
≥ -90 dBm Good Good signal and speeds with no dropouts expected
≥ -110 dBm Fair to Poor Fair/usable signal with possibility of dropouts and slowdowns
≤ -120 dBm Unusable No usable signal - expect frequent disconnections and sluggish performance

 

RSRQ - Reference Signal Received Quality

RSRP Quality Description
≥ -5 dBm Excellent Strong signal enabling maximum data capacity
≥ -8 dBm Good Good signal and speeds with no dropouts expected
≥ -10 dBm Fair to Poor Fair/usable signal with possibility of dropouts and slowdowns
≤ -20 dBm Unusable No usable signal - expect frequent disconnections and sluggish performance

 

SNR - Signal to Noise Ratio

This is the ratio of interfering noise to the actual signal you are using.  The higher the ratio, the louder and clearer your signal can be "heard" over all the background noise, leading to better performance.  While it is possible for our modems to transmit some data in a negative signal to noise ratio you will certainly not find it to be the best experience, which is why recommend keeping it above 0 dB, which represents the signal and noise levels being equal to one another.

RSRP Quality Description
≥ 15 dB Excellent Strong signal enabling maximum data capacity
≥ 10 dB Good Good signal and speeds with no dropouts expected
≥ 3 dB Fair to Poor Fair/usable signal with possibility of dropouts and slowdowns
≤ 0 dB Unusable No usable signal - expect frequent disconnections and sluggish performance
