物联网的快速发展对无线通信技术提出了更高的要求，专为低带宽、低功耗、远距离、大量连接的物联网应用而设计的LPWAN（low-power Wide-Area Network，低功耗广域网）也快速兴起。LoRa是其中的典型代表，也是最有发展前景的低功耗广域网通信技术。

-The rapid development of the Internet of Things wireless communication technology put forward higher requirements, designed for low-bandwidth, low-power, long-distance, large numbers of connections and networking applications designed LPWAN (low-power Wide-Area Network, Low Power WAN) are rapidly emerging. LoRa is one of the typical, is the most promising low-power wide area network communications technology.
