We’re using +KCELL=1 on the HL8548 to get information about neighboring towers. We’re interested in getting the physical channel power for each tower, similar to what we can retrieve with the $CSQ command.
Based on the AT Guide (version 19), GSM towers return RSSI which is an offset of -110 dBm. Is the resulting value equivilent to the physical channel power from $CSQ?
For UMTS towers, $CSQ returns Ec/No in addition to rssi. Is my understanding correct that in order to get physical channel power, we need to do (rssi * 2 - 113) + Ec/No ?
Similarly, for UMTS on KCELL, there is an rscp and ecno value, but they appear to have different ranges than the same in $CSQ. How do we calculate physical channel power from these values in KCELL?
