Multiply this number by 550, and the result is the distance from the RBS (Radio Base Station), in meters.

Get Signal Quality - press [MENU] until 'Eng Field Option' is displayed, press [OK], select 'Active Cell', press [OK], press [MENU] until 'C1' appears. This is the signal quality. If it becomes negative for longer than 5 seconds, a new cell is selected.
