Design of industry wireless network node based on IEEE802.15.4a

In accordance with the issues of wireless data communication in industry automation field and the less research of chirp spread spectrum in China,the design of wireless node from the view of application is presented,based on the wireless IEEE802.15.4a standard. The basic hardware circuits and software flow chart are given. Through the tests on prototype nodes,in which the traditional CSMA/CA is used,these design nodes based on chirp spread spectrum technology can run stably under intense electromagnetic interfere-nce environment. The real-time performance satisfies the design requirement,and these nodes is used in the industrial wireless field.
