M2M 通信被定位为未来十年增长最快的技术领域之一。传感器和执行器网络连接通信机器和设备，以便它们自动传输信息，满足日益增长的环境数据采集需求。 IEEE 802.11ah 任务组正在制定一项新标准，以满足 M2M 网络的特殊要求：大量功率受限的站点；传输距离远；小且不频繁的数据消息；低数据速率；和非关键延迟。本文探讨了该新标准的主要特征，特别是与减少介质访问控制层能耗相关的特征。鉴于这些要求，提出了 IEEE 802.11ah 在四种常见 M2M 场景（即农业监控、智能计量、工业自动化和动物监控）中的性能评估。
M2M communications are positioned to be one of the fastest growing technology segments in the next decade. Sensor and actuator networks connect communication machines and devices so that they automatically transmit information, serving the growing demand for environmental data acquisition. The IEEE 802.11ah Task Group is working on a new standard to address the particular requirements of M2M networks: a large number of power-constrained stations; a long transmission range; small and infrequent data messages; low data rates; and a non-critical delay. This article explores the key features of this new standard, especially those related to the reduction of energy consumption in the medium access control layer. Given these requirements, a performance assessment of IEEE 802.11ah in four common M2M scenarios, i.e. agriculture monitoring, smart metering, industrial automation, and animal monitoring, is presented.
