In 2020, domestic operators will start to open 5G networks, and for the current situation, 4G networks have developed very thoroughly. Let's take a look at the related content with the network communication Xiaobian.
According to the data given by the three major operators last year, in 2017, the total number of 4G subscribers of Telecom, China Mobile and China Unicom reached 182 million, 650 million, and 175 million, respectively. After the user surged, they entered the flat period of 4G development.
According to the 21st Century Business Herald, it is the key task of the three major operators this year to move 2G users to 4G and push 2G out of the network as soon as possible.
Interestingly, China Unicom has already said in its earnings report that it will accelerate the 2G migration 4G, effectively use resources, and promote 2G/3G network frequency reduction and volume reduction, while telecommunications and mobile are preparing for the same thing.
In fact, more than 20 operators including Japan, South Korea, the United States, Singapore and other countries and regions have officially closed the 2G network and completed the user migration. After 2G exits the network, the high-quality frequency band originally used for 2G can be reused, and the 2G spectrum is used for 4G network and NB-IoT network construction, which can achieve lower construction cost.
