摘要
当今万物互联的时代,大量设备连接的需求促使"低功耗广域网络"技术标准的和商用化进展加速,成为物联网领域最为热门的话题。文章从补齐物联网通信层短板的角度分析低功耗广域网络在物联网产业中的地位,并对低功耗广域网络的发展历程进行回顾。针对当前低功耗广域网络商用中的市场格局,阐述以NB-IoT、LoRa为代表的两大主流阵营的市场格局,并从产业经济学的角度,对NB-IoT、LoRa产业链各环节的市场集中度进行对比分析,探索国内市场上低功耗广域网络的市场竞争状况,并认为最终NB-IoT、LoRa可能都会成为该领域主流技术,两者将定位于不同市场领域,共存发展。
In the Internet of Thins era, mass of devices will connect to the Internet. The demands of connectivity promote the progress of technology standards and commercialization of ＂Low Power, Wide Area Network （LPWAN）＂. LPWAN is a hot topic of lot now. The author realizes LPWAN as the best way to make up the short slab of IoT communication layer. The history of LPWAN is reviewed in this article. For exploring the market situation of LPWAN, the author makes a status report of NB-IoT and LoRa. The author also makes comparison of market concentrate rate of NB-IoT and LoRa, and gets the competition situation of this area in China market.
