signal stength in db? (series 60)

[Phia]

Hello!

Does anybody know if it is possible to get the absolute signal strength in db in series 60? Currently all I have is the percentage, but as I know, I cannot map this to db, because not all stations send with the same max stength.

In practice, it should be possible to read the dbs, because e.g psiloc has done this already.

Somewhere they said, they did this by reading the C2 register.

Has anyone a clue what this register can be and how one could read it out?

Or is there another way to do this?

hopefully,
phia

Hi,

MiniGps doesn't read signal strength in dbm from the phone. The software use the same "Per cent"- measurement (with the "GetSignalStrength"-function ) and convert it to dbm.
The C2 is the cell-reselection criterion and select the serving-cell (strongest Cell) from all available cells in the neighbourhood. The criterion include no information about signal strength. Only the C1 (path-loss criterion) contains those information but i have no idea how to read it out. At the Moment i think the only way to get the signal strength in dBm is SAT (SIM application toolkit). But i try this for two months and the SIM-Card doesn't speak with me....

Alex,

did you find the way to convert the signal strength from percent into dBm ? I found a formula ( dBm = log mW *10 ) that converts the signal from mW into dBm , but I don't know how to obtain the power of the signal in mW.
