Ministry of Industry and Information Technology: Promote the collaborative development of NB-IoT and 4G, 5G
On May 7, the official website of the Ministry of Industry and Information Technology issued the “Notice of the General Office of the Ministry of Industry and Information Technology on Deepening the Comprehensive Development of the Mobile Internet of Things.”The notice requires that we must accurately grasp the global mobile IoT technology standards and industry pattern trends, promote the migration and transfer of 2G / 3G IoT services, and establish NB-IoT (narrowband Internet of Things), 4G (including LTE-Cat1, that is, rate category)1 4G network) and 5G coordinated development of a comprehensive ecosystem of mobile Internet of Things.The notice pointed out that on the basis of deepening 4G network coverage and accelerating the construction of 5G networks, NB-IoT should be used to meet the needs of most low-rate scenarios, and LTE-Cat1 (hereinafter referred to as Cat1) to meet the needs of medium-rate IoT and voice.5G technology meets the needs of higher speed and low latency networking.NB-IoT refers to the Narrowband Internet of Things (NB-IoT).It is understood that NB-IoT only consumes about 180kHz of bandwidth and can be directly deployed on GSM networks, UMTS networks or LTE networks, which can reduce deployment costs and achieve fine upgrades.The notice requires that by the end of 2020, the NB-IoT network should achieve universal coverage in the main urban areas of cities above the county level and in-depth coverage in key areas; the number of mobile IoT connections will reach 1.2 billion; promote the convergence of NB-IoT module prices and the 2G model, and guide newIncrease the migration of IoT terminals to NB-IoT and Cat1; create an application scenario that expands NB-IoT application benchmarking engineering and NB-IoT million-scale connection scale.The reporter promised to edit Sun Yong proofreading Li Xiangling
