Abstract


Considering the features of indoor positioning, this paper represents a regional RFID based dual-frequency positioning system. The mode, this paper intends to present, of waking up at low frequency of 125KHZ and transmitting at high of 433MHZ, makes it possible to realize the better communication and be adapted to the complex regional environment. The testing proves that, in the indoor complicated environment, the system can keep working steadily, and, with increased the number of antennas, that the positioning precision can reach less than 20cm and accuracy more than 96%.
