Research on positioning system based on Zigbee communication

This paper presents a three-dimensional layered localization method based on Zigbee communication, can be effectively used for indoor positioning. The three methods of RSSI ranging model and hierarchical positioning algorithm. To solve the problem of traditional Zigbee communication three-dimension large localization error. Using the design of 3D layered localization algorithm of Zigbee communication indoor positioning system based on vertical environment. To effectively solve the error problem, to achieve accurate positioning. The sensing characteristics of Zigbee are analyzed, the calibration of A and effect of n value on Zigbee communication.
