Abstract: The paper introduced principle of remote data transmission through GPRS and shortrange data transmission through ZigBee, proposed a wireless network structure combining ZigBee and GPRS, and gave designs of software and hardware of the wireless network structure. The wireless network structure transmits data through GPRS in wide area and through ZigBee in local area and realizes a new type of multi-mode network structure, which provides a simple method for building wireless link between terminal, remote device and personnel.
