Value:

((snr) - SNR_OFFSET_VAL)

Converts SNR index value returned by the modem to dB.

The index value of SNR can be converted to dB with the following formula:

• index – 24

Example values:

• 0: SNR < -24 dB
• 1: -24 ≤ SNR < -23 dB
• 2: -23 ≤ SNR < -22 dB
• ...
• 47: 22 ≤ SNR < 23 dB
• 48: 23 ≤ SNR < 24 dB
• 49: 24 ≤ SNR dB

See modem AT command reference guide for more information.

Parameters

[in]
