You are right, a phone's ability to maintain a call varies. Also, bad
reception is the simplest explanation for a dropped call, but there are
other more complex scenarios. For example in the
GSM world 'cell
hand-over' (when your call is seamlessly transfered between BSU's) is
an issue and often experienced by people when driving or walking.
A carrier will test to standards (in
GSM that would be GCF
certification) to allow an air-interface on their network by ensuring
that in a simulated environment a handset can perform functions like
hand-over. Often, in the real world, this is not the case.
Carrier testing often encompasses 'drive testing' where a van will
drive a pre-specified route and monitor the signal by placing voice and
data calls. However, they do not test every handset / air-interface
available so this testing is inherently flawed in finding problem areas.
I put together
http://www.droppedcallr.com to allow people to have a
voice for reporting issues and at the moment, it is in a simple form.
In the next build, I'm going to update droppedcallr to also allow users
to add the make/model of their phone which should not only allow for
more relevant data to be recorded for each reported issue but also
allow better feedback on which handsets might be effected.
