The strength field or dBm shown by the GPRS modem (the classic bars displayed by a GSM telephone) is
displayed among the information given by the command and it is identifiable, in the example above, by the
Signal Quality: +CSQ: 17,99.
The strength field value can also be obtained starting from the value CSQ. In the example above, the
strength field (dBm) is calculated by a simple arithmetic operation:
CSQ*2 - 113 = dBm
17 * 2 – 113 = -79
With the value obtained it is possible to understand the available signal level (the classic bars on a cell
phone display):
