Goodbye, 2G.China Unicom officially announced 2g service would discontinue since 2018 April


On April 12th, according to a notice from inside China Unicom, a company in China Unicom is conducting a 2G base station declining and retiring service, and plans to shut down 101 low-traffic base stations. In order to develop 4G, China Unicom began. Accelerate the withdrawal of 2G.


China Unicom confirmed this news. In fact, at the end of January this year, China Unicom has been actively deploying 2G network retreat work in many provinces and cities, and requires the market line to strictly prohibit the development of 2G services.

China Unicom

Why did China Unicom choose to shut down 2G?


According to the analysis, China Unicom has closed 2G, which may contain three reasons:


Firstly, in order to transfer spectrum resources, China Unicom will shift the resources of 2G networks to 4G, which will benefit the development of the industry.


Secondly, this can greatly reduce maintenance costs;


Thirdly, last year, the Ministry of Industry and Information Technology issued a document to allow operators to deploy NB-IoT systems in the GSM frequency band. Later, China Mobile built a 4G-based NB-IoT network on the original 2G frequency band. Therefore, 900Mhz and 1800Mhz deployed 2G networks. It is regarded as a high-quality frequency band, and it is also a resource that Unicom urgently needs. For these reasons, China Unicom has chosen to close the 2G network.


2G withdrawal is the trend of the times


Closing 2G is not a domestic precedent, and many foreign operators have closed 2G networks. In January last year, operators such as AT&T, Bell, and Telus in the United States shut down 2G networks. In April, three Singaporean operators, M1, Singtel, and StarHub, Australia's second-largest telecom operator Optus also shut down 2G networks. At the end of July last year, another Canadian operator, SaskTel, will also shut down the 2G network; at the end of September, Australia's Vodafone closed the 2G network.


Faced with a series of global 2G network operations, it also indicates that 2G communication is slowly withdrawing from the historical stage. Closing the 2G network is already an international trend, and for operators, shutting down the CDMA network is conducive to investing 4G or 5G in the vacated 2G frequency band, expanding network coverage and enhancing network capacity.
