Co-construction and sharing are still 5G keywords

The benefits of co-building and sharing are self-evident. If China Mobile and China Radio and Television join forces, there will also be many benefits. China Radio and Television should start from scratch in terms of 5G construction, lack technology and talent base, and also face huge capital investment difficulties. No matter what choices are made, co-construction and sharing should be the key words.

The Ministry of Industry and Information Technology announced on January 3 that it had issued a 4.9GHz band 5G test frequency license to China Radio and Television Network Co., Ltd. (hereinafter referred to as "China Radio and Television") and agreed to deploy 5G networks in 16 cities. This frequency band is consistent with the previous 5G test frequency band for China Mobile. In addition, China Unicom and China Telecom have started to build and share 5G networks. The industry speculates that China Radio and Television may build a 5G network with China Mobile.

In June 2019, China Radio and Television won the 5G commercial license issued by the Ministry of Industry and Information Technology, becoming the fourth 5G basic telecommunications operator in China after China Telecom, China Mobile and China Unicom. This test frequency license marks that China Radio and Television has officially obtained the right to use 5G frequencies in relevant areas. Earlier, the Ministry of Industry and Information Technology issued 5G system test frequency licenses to the three major telecommunications operators. Both China Telecom and China Unicom have obtained 100MHz bandwidth in the 3.5GHz band, and China Mobile has obtained a total of 260MHz bandwidth in the 2.6GHz and 4.9GHz bands. . This time, China Radio and Television obtained the 4.9GHz band.

China Unicom and China Telecom are in the same 5G test frequency band. In September 2019, the two announced that they will jointly build and share a 5G network. In other words, in the future, China Unicom and telecommunications users will use the same 5G network. China Unicom and China Telecom also demarcate areas and districts, and are responsible for 5G network construction work within the demarcated areas, who constructs, invests, maintains, and bears network operation costs.

The benefits of co-building and sharing are self-evident. The first is to save money. Although 5G has high performance, the investment cost to be paid is also very high. It is difficult to achieve large-scale 5G network coverage in a short time by the power of an operator, and co-construction and sharing will greatly reduce repeated investment and construction. The second is complementary advantages. For example, in terms of transmission networks, Unicom has abundant resources in the north, telecommunications has more resources in the south, and Unicom also has rich resources in the construction of mobile networks in the south. Joint construction and sharing will help Unicom and Telecom to efficiently achieve 5G network coverage, quickly form 5G service capabilities, enhance the market competitiveness of 5G networks and services, and improve network efficiency and asset operation efficiency.

If China Mobile and China Radio and Television join forces, there will also be many benefits. However, China Mobile has been far ahead in the 4G era, and has also stepped up its deployment in the 5G era. The advantages are obvious. So, what are the advantages of China Radio and Television?

Earlier, Wang Zhiqin, deputy dean of the China Academy of Information and Communications Technology, said that from foreign experience, a healthy communication network requires only three or four companies to ensure both competition and reasonable input. The licensing of radio and television is both to promote competition and to promote the joint construction and sharing of 5G networks. At the same time, this will also promote broadcasting and television to retreat its own 700MHz frequency band resources for 5G construction.

The 700MHz band is recognized as the "golden band" by the industry. It is understood that compared to the 2.6GHz, 3.5GHz and 4.9GHz bands of the three major operators, the 700MHz gold band has lower frequencies, has the advantages of low signal transmission loss, wide coverage, strong penetration, and low networking costs. It is especially suitable for deploying a wide coverage IoT. At present, the Internet of Things is considered to be the most promising area for 5G killer applications. It is understood that China Radio and Television has joined the 3GPP international organization to lead the development of the 700MHz 5G international standard and plans to complete it before the 3GPP R16 version freezes in March 2020.

In 2019, China opened 126,000 5G base stations and achieved 5G commercialization in 52 cities. In this year, China Mobile's investment in 5G was about 24 billion yuan, and China Unicom and China Telecom's 5G investment were about 8 billion and 9 billion yuan, respectively. It is expected that more than 400,000 5G base stations will be deployed in China this year, and all prefecture-level cities nationwide will cover 5G networks by the end of this year. China Radio and Television needs to start from scratch in 5G construction, lacks a technical and talent base, and will also face huge capital investment difficulties. Therefore, no matter what you choose, co-construction and sharing should be the subject. (Economic Daily-China Economic Network Huang Xin)
