Design of WSN gateway based on ZigBee and TD

Abstract

According to problems caused by limited bandwidth of traditional wireless sensory gateway, such as inferior network performance and low efficiency of communication, this paper comes up with a solution — a wireless sensory gateway based on ZigBee/TD, closely combining ZigBee net with TD-SCDMA net. In the plan of design, the network node transport data to gateway by ZigBee short-range communication technique after collecting them and the gateway send them to control center by TD network from long distance, realizing the highly efficient long-range transport of data. To sum it up, this design satisfies the efficiency and transparency needed for inter-networks data exchange and it can be extended easily.
