The quality of internet connection on basis of CINR and RSSI

RSSI is what we call Received Signal Strength indicator which is basically the level of received signal strength in dBm.

CINR is what we call Carrier to Interference+Noise Ratio which is basically the signal to noise ratio in dB

 

RSSI from -50 to -85 dBm

  

You would want RSSI to be closer to -50 than to -85

 

CINR from 10 to 30 dB

• You would want CINR to be closer to 30 than to 10
• At most value of 20 or more can be considered a ""good signal""
• At least value of 15 or less will probably trigger your modem to try to swap to another tower  

1Mbps connection with RSSI of -79.50 and CINR of 12.56 is marginal.
