AT+CSQ (Signal Quality Measurement)

With data calls signal strength is important, particularly in regard to GPRS connections. AT+CSQ command returns the Signal Quality Measure (SQM). This is a Signal to Noise Ratio measurement that is used to ascertain the relative quality of the received cellular signal. There is no standard in regard to this measurement, other than most manufacturers report CSQ'S between 0 and 31. To have a reliable GPRS connection a minimum CSQ value of 20 is recommended. To convert the CSQ to a Received Strength Signal (RSSI) or dBm value, you must assume a noiseless environment. The dBm figure may be worked out using the formula:

dBm = -113 +n x 2, where n is the CSQ.

For example a CSQ of 20 would equate to a dBm of -73. The lower the dBM reading the better.Preferred values for GPRS connections would be dBm readings within the 50 range. A table is enclosed which visually shows dBm readings for different values of CSQ.
