- 信息技术－会议论文 
The paper put forward a detail design of the out-of-position alarm system based on ZigBee technology and communication chip CC2430 to protect valuables from leaving safe position. It introduced the hardware and software design of the system, implemented short-range wireless communication, established the functional relationship between received signal strength indication (RSSI) and wireless communication distance, solved the problem of multipath fading by software method. Then it presented a series of experiments to prove the system can steadily communicate information to meet security requirement.
