摘要
讨论物联网标准NB-IoT的发展现状和技术特点,重点阐述GSM演进至NB-IOT、FDD的三步骤,即将GSM频率重耕至NB-IoT和FDD,GSM老旧设备改造成NB和FDD适配的设备。最后,结合工程实例,进一步提出了NB-IoT和FDD统一部署的建议。
This paper discusses the development status and technical characteristics of the Internet of Things standard NB-IoT,focusing on the three steps of the evolution of GSM to NB-IOT and FDD,that is,replanting the frequenc y of GSM to NB-IoT and FDD,and transforming the old equipment of GSM into equipment adapted to NB and FDD. Finally,the unified deployment of NB-IoT and FDD is proposed with engineering examples.
