摘要
基于无线射频(Radio Frequency,RF)信号传输模型,结合实际应用,分析了接收信号强度指示(Received Signal Strength Indicator,RSSI)与通信距离的关系,为无线信号的测距与定位提供了基本依据。使用低成本、低能耗的RF收发芯片CC1101,设计无线传输电路,测得了大量的RSSI值,分析了CC1101的传输距离对环境的要求,为无线传感网络中RF收发芯片的测距、定位和数据传输应用提供参考。
Through the wireless RF signal transmission model,combing with the practical application,this paper gave an analysis of the relationship between RSSI and the communication distance,which provided the basis for the distance measuring and positioning of the wireless signal.Using a low cost and low energy consumption RF transceiver chip CC1101,the paper designed a wireless transmission circuit,obtained a large amount of RSSI data,gave an analysis about the environment demands for the CC1101 transmission distance,and provided a reference for the RF transceiver chip application in distance measurement,positioning and the data transmission in wireless sensor networks.
