摘要
为解决传统的物联网(IoT)通信设备功耗大、需要人工定期维护、频繁更换电池等问题,该文提出一种基于电磁波能量收集的无源WiFi物联网散射通信方法。该方法基于低功耗微处理器实现WiFi反向散射通信,同时利用自身收集的电磁波能量实现系统自供电,具有功耗低、无需电池、体积小、成本低、免人工维护、容易大量部署等诸多优势,可广泛用于物联网领域。
To solve the problems of high power consumption,requiring manual maintenance and frequent battery replacement of traditional Internet of Things(IoT)communication device,a passive WiFi IoT backscattering communication method based on electromagnetic wave energy harvesting is proposed.The device is implemented based on a low-power microprocessor platform.It can use the electromagnetic wave energy collected by itself to achieve ultra-low-power WiFi scattering communication,having advantages of low power consumption,no batteries,small size,low production cost,and no manual maintenance.It can be widely used in IoT applications.
