Summary

This chapter is an overview of recommended signal strength levels for different mobile service modes.

Signal Measurement

Signal strength values are defined by a few different measurements which vary even more for different service modes. These measurements are as follows:

  • RSSI
  • RSRP
  • RSRQ
  • RSCP
  • SINR
  • EC/IO

2G (GSM)

2G (GSM) Signal strength is defined by only one value: RSSI – Received Signal Strength Indicator;

RSSI Signal strength
> -70 dBm Excellent
-70 dBm to -85 dBm Good
-86 dBm to -100 dBm Fair
< -100 dBm Poor
-110 dBm No signal

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

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

  • RSSI - indicates the received signal strength
  • EC/IO - indicates the downlink carrier-to-interference ratio (signal quality)
  • RSCP - indicates the received signal code power
EC/IO Signal quality
0 to -6 Excellent
-7 to -10 Good
-11 to -20 Fair to poor
