ABSTRACT:
An antenna-assisted two-point positioning system for positioning a mobile device is disclosed. The antenna-assisted two-point positioning system comprises a first wireless communication module comprising first antennas, a second wireless communication module comprising second antennas, a storage module, and a processing module. The mobile device transmits a first signal strength to a first antenna for a first receive signal strength and a second signal strength to a second antenna for a second receive signal strength. The second wireless communication module and the first wireless communication module determine a first position and a second position corresponding to the mobile device. The storage module stores first antenna gain tables corresponding to the first antennas and second antenna gain tables corresponding to the second antennas. The processing module is used for judging whether an environmental interference factor is ignorable to selectively judge that the mobile device is located at the first or second position.
