WIRELESS TRANSMITTING/RECEIVING SYSTEM, WIRELESS RECEIVING DEVICE AND WIRELESS TRANSMITTING/RECEIVING METHOD
First Claim
1. A wireless transmitting/receiving system comprising:
- a transmitter disposed on a target object, the transmitter transmitting a wireless signal;
a first directional receiver disposed with respect to an entry/exit boundary, the first directional receiver receiving the wireless signal and generating a first received signal strength indication;
a camera capturing an image of the entry/exit boundary;
a storage device storing a mapping table of target object location and received signal strength; and
a processor electrically connected to the storage device, the processor determining a location of the target object and a moving direction of the target object with respect to the entry/exit boundary according to the image and the mapping table of target object location and received signal strength.

Abstract
A wireless transmitting/receiving system includes a transmitter, a first directional receiver, a camera, a storage device and a processor. The transmitter is disposed on a target object and transmits a wireless signal. The first directional receiver is disposed with respect to an entry/exit boundary. The first directional receiver receives the wireless signal and generates a first received signal strength indication. The camera captures an image of the entry/exit boundary. The storage device stores a mapping table of target object location and received signal strength. The processor is electrically connected to the storage device and determines a location of the target object and a moving direction of the target object with respect to the entry/exit boundary according to the image and the mapping table of target object location and received signal strength.
