Peter asked " how can one access this "timing advance facility" - accuracy not being of much importance. "
Unfortunately YOU cannot. It is a system used by the network to ensure that the noughts and ones making up the signal arrive at the handset at the correct time to be decoded with minimum errors. Their transmission is advanced the further you are away from the cell site to allow for a longer delay as they rush through space. The Network operators are able to view the settings on the cell you are using and the others your mobile can see therefore allowing them to triangulate and locate the mobile. They do sell the service to accredited companies who use them to provide location finding services to worried parents, policemen etc. If your old Diga had an engineering mode then you might have been able to view the setting for your current cell.
