摘　　要：IEEE802.15.4技术标准主要面向近距离、低速率、低功耗特性的物联网通信应用场景,该标准规定了LR-WPAN(Low-Rate Wireless Personal Area Network)物理层和媒体访问控制层(MAC)。随着物联网的快速发展,NB-IoT、LoRa、Sigfox、Wi-SUN等面向低功耗、广覆盖特性的LP-WAN(Low Power-Wide Area Network)通信技术标准应运而生。WiSUN(Wireless Smart Utility Network)协议栈基于802.15.4g物理层通信标准,主要使用900MHz带宽(917-923.5MHz),发射功率从10mW至200mW,在海外主要应用于电力物联网通信。The IEEE802.15.4 technical standard is mainly oriented to the communication scenarios of the Internet of Things with short-distance, low-rate, and low-power characteristics. The standard specifies the LR-WPAN(Low-Rate Wireless Personal Area Network) physical layer and media access control layer( MAC). With the rapid development of the Internet of Things, LP-WAN(Low Power-Wide Area Network) communication technology standards for low power consumption and wide coverage characteristics such as NB-IoT, LoRa, Sigfox, and Wi-SUN have emerged. The Wi-SUN(Wireless Smart Utility Network) protocol stack is based on the 802.15.4 g physical layer communication standard. It mainly works at 900 MHz frequency band(917-923.5 MHz) and a transmission power from 10 mW to 200 mW. It is mainly used for power IoT communications overseas.
