Abstract
A system and method is provided to track positions of a portable electronic device. Different communication modules capable of retrieving position signals are enabled selectively according to the status/type of position signals of the portable electronic device. All of the different communication modules are enabled when the portable electronic device locates around a boundary between different regions that require different communication modules to obtain geography information. Therefore, by means of seamless transferring operation between different communication modules, a remote manager may be able to continuously monitor the positions of the portable electronic device.
