I'm sorry I wasn't clear. I meant that the phone doesn't measure the
recieved signal strength - it's all the same to it as long as it's there
(and if it's missing or partialy missing the phone cannot do much about
it). According to the GSM spec, after the handshake, the base station
and the phone negotiate to find an optimal power level for the phone
(the base station always transmits at full power)
So when the coverage indicator is one bar, this means that the phone
transmits at full power, and when it is four bars means that it
transmits at min power.
note: actually, I'm speaking for GSM and its variations. Not sure if
this applies to UMTS as well.
note2: it seems this has already been discussed here -
