Abstract:ZigBee is a short-range, low-power, and low-rate wireless communication for mobile electronic devices. Which is widely used in many areas, such as intelligent transport, environment monitoring and so on. Nowadays it has become a research and applied hotsphotspot. This paper analyzes and synthesizes ZigBee network topology, routing method and interconnect technology based on ZigBee gateway. At last it proposes the Zigbee technical problem that needed to be solved and future research directions.
