摘要
近十年来,物联网技术得到飞速发展,传统的近距离物联网技术市场应用显现不足,随着万物相连,物物上平台的发展趋势,使得一种低功耗、广覆盖、支持大量终端节点的低功耗广域网得到极大的关注和发展。为了适应物联网技术的飞速发展,文中对现有低功耗广域网的技术进行分析,重点介绍了LoRa、SigFox、NB-IoT三大技术特点。
In the past ten years,the Internet of Things technology has developed rapidly,and the traditional application of the near-field Internet of Things technology has become insufficient.With the connection of everything,the development trend of the platform on the object makes a low power consumption,wide coverage,and supports a large number of terminal nodes.The low-power WAN has received great attention and development.In order to adapt to the rapid development of Internet of Things technology,the paper analyzes the existing low-power WAN technology,focusing on the three technical features of LoRa,SigFox and NB-IoT.
