A 4.9GHz band 5G test frequency license has been issued to China Broadcasting Network, the country's fourth telecom operator in the 5G era, allowing it to deploy 5G networks in 16 cities including Beijing, the Ministry of Industry and Information Technology said on January 3.
As the 4.9GHz test frequency is consistent with China Mobile's frequency, China Broadcasting Network may build a 5G network with China Mobile, 21st Century Business Herald quoted industry sources as saying.
In terms of technical feasibility, existing filters and PA and other equipment can support 200MHz bandwidth, and two operators with adjacent frequencies can share the same network equipment, the report said.
In terms of necessity, the 4.9GHz frequency is higher, and the continuous coverage of 5G requires more base station investment. At present, China Broadcasting Network does not have sufficient capital, technology and talents to form a 5G network independently, so building a 5G network with China Mobile is a practical choice, the report said.
China Broadcasting Network plans to officially implement 5G commercialization in 2020, adopting a 700M + 4.9G low frequency + intermediate cooperative networking strategy, and directly adopting stand-alone networking routes, while developing retail business and industry vertical applications.
On June 6, 2019, the Ministry of Industry and Information Technology issued 5G commercial licenses to operators in China. In addition to the three major operators, China Broadcasting Network also obtained a 5G commercial license, becoming China's fourth 5G basic telecommunication after China Telecom, China Mobile and China Unicom.
On September 9, 2019, China Unicom announced that it has signed an agreement with China Telecom to jointly build a 5G network. The two sides demarcated the area and divided the area into construction.
In the five cities in the north, the ratio of China Unicom to the construction area of telecommunications is 6:4; in the ten cities in the south, the ratio of China Unicom to the construction area of telecommunications is 4:6.
