摘要
认为低功耗物联网(IoT)业务所面临的挑战主要包括:在网络和终端方面,模组成本高,耗电量大,网络覆盖不理想;在运营方面,增量不增收,业务碎片化。窄带物联网(NB-IoT)能有效解决当前低功耗业务所面临的问题,相比LoRa等非授权频谱低功耗广域物联网(LPWAN)技术,在移动性、可靠性和安全性等方面具有优势,更适合规模化运营。提出了运营商的NB-IoT运营策略,包括迅速部署NB-IoT网络,突破网络连接服务,聚焦重点行业,加强产业合作。认为NB将会成为LPWA的主流技术。
Main challenges faced by low power enabled Internet of things(IoT)services include two aspects:high module cost,high power consumption,badnetwork coverage for network and terminal;the increasing connectivity(while theincome does not increase),and the fragmentation of services in operation.Comparingwith other un-authorized spectrum low power wide area(LPWAN),e.g.,LoRa,narrowband IoT(NB-IoT)has many advantages in terms of mobility,reliability andsecurity,so it is more suitable for large scale operation.NB-IoT operation strategiesare proposed in this paper,including quickly deploying NB-IoT network,expandingthe network connection services to upper services,focusing on key industries andstrengthening industrial cooperation.NB will become the main technology of LPWA.
