C114 June 28 (Yue Ming) According to netizens from "Communication Home", in order to implement the central government's decision-making and deployment, China Mobile Group has carried out IoT technology, business development strategies and strengthening NB-IoT network construction. After conducting a special survey, it is clear that NB-IoT and 4G Cat1/1bis technology will undertake 2G IoT services, and it is decided to stop adding 2G IoT users by 2020
At the same time, in order to speed up NB-IoT network coverage and accelerate the migration of 2G IoT services to NB-IoT networks, effectively promote 2G frequency-returning and network-removing and 900MHz frequency recultivation, China Mobile will build 118,000 new NB-IoT base stations nationwide in 2020 A total of 350,000 base stations.
The industry believes that China Mobile has the world's largest IoT connection scale, but it is mainly based on 2G IoT business. It is very urgent for China Mobile to stop adding 2G IoT users to the network and gradually realize the migration of existing users. , Is also a very challenging measure.
At the same time, although the NB-IoT industry chain is accelerating maturity and migration costs are declining, it still faces many challenges such as exploring new business models and ROI. Therefore, China Mobile hopes to achieve the network with the industry at the same time to create network advantages, accurately invest resources and ensure investment income.
In May of this year, the General Office of the Ministry of Industry and Information Technology issued the "Notice on Further Promoting the Comprehensive Development of the Mobile Internet of Things" to promote the migration and transfer of 2G/3G Internet of Things services and establish a comprehensive ecosystem of mobile Internet of Things with NB-IoT, 4G, and 5G collaborative development. The system uses NB-IoT to meet the needs of most low-rate scenarios, LTE-Cat1 to meet the needs of medium-rate IoT and voice, and 5G technology to meet the needs of higher-speed, low-latency networking.
The "Notice" requires that by the end of 2020, the NB-IoT network will 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 2G modules. Guide the migration of newly added IoT terminals to NB-IoT and Cat1; create a batch of NB-IoT application benchmark projects and NB-IoT million-scale connection scale application scenarios.
As a key part of the mobile IoT industry ecology, the "Notice" requires strengthening the supervision of mobile IoT products entering the network, guiding new IoT terminals to stop using 2G/3G networks, and promoting the stock of 2G/3G IoT services to NB-IoT /4G (Cat1)/5G network migration.
