A positioning system and method are provided. The positioning system includes a wireless signal source disposed at a known fixed location in an area and a handheld electronic device. The handheld electronic device includes a compass, a wireless transmission module and a processing module. The processing module retrieves information of fixed direction from the compass, determines a first azimuth angle among the handheld electronic device, the wireless signal source, and the fixed direction according to a maximum signal strength between the wireless transmission module relative to the wireless signal source, and determines a first distance between the handheld electronic device and the wireless signal source according to a first wireless transmission parameter between the wireless transmission module and the wireless signal source. The processing module further determines a first absolute location of the handheld electronic device according to the first azimuth angle and the first distance.

Positioning system and method

A near field communication and wireless charging device includes a coil, a tuning module, a near field communication module, a wireless charging module, and a power storage device. The coil is configured to receive electromagnetic waves. The tuning module is electrically connected to the coil. The near field communication module includes an attenuator and a near field communication control circuit. The attenuator is configured to attenuate the energy of electromagnetic waves transmitted from the tuning module. The near field communication control circuit is electrically connected to the attenuator. The power storage device is electrically connected to the wireless charging module. Electromagnetic waves are magnetically coupling to the coil, and the coil transmits signals of the electromagnetic waves to the near field communication module through the tuning module, or transmits the energy of the electromagnetic waves to the power storage device through the tuning module and the wireless charging module.
