Do you want to send 3.5G band to China Mobile?

Taking China Mobile as an example, Xu Xiaodong became the vice-chairman of RAN plenary session, Hu Nan became the vice-chairman of RAN2 working group, Huang Zhenning became the vice-chairman of CT3 working group, Sun Tao became the project reporter of 5G system architecture, Song Yue became the project reporter of 5G network protocol standard research and formulation, Ni Jiqing became the main contributor of NR waveform project, Chen Zhuo. As eVoLTE reporter, Wang Sen became the main contributor to RAN NOMA project, and Chen Yamin became the main contributor to CU / DU separation project.

Commercial landing in the United States is leading.

But when 5G landed, the US took the lead in China. Not only did 5G have a clear spectrum division, but the US carriers have already started 5G commercial deployment. Not long ago, T-Mobile, an American operator, signed orders with Nokia and Ericsson for a total of $7 billion.

That means the U.S. 5G network will soon be built on a massive scale, and it means that China's telecoms industry, which has struggled from lagging to running to the world's leading position, is likely to lag behind the U.S. once again in the final commercial landing.

Although our country has divided the spectrum of 5G, it is difficult for the three operators to invest in the construction of 5G network because of the lack of specific allocation of spectrum to the three operators, so they can only wait for the final result of 5G spectrum division.

And when the U.S. has begun commercial deployment of 5G networks, China needs to catch up with the U.S. 5G schedule. This is not only very important to the status of China and the United States communications industry in the global market, but also related to the future of China and the United States economy.

"The center of future global technological change is likely to change as a result of the 5G race," the Global Economic Policy Committee said in a report. National competitiveness will increasingly depend on the application and innovation level of the fourth industrial revolution technology, and ultimately depends on the quality of the national 5G wireless network. Winning the 5G race needs to ensure that 5G covers a wide range and goes deep into a specific market. Only then will the benefits of these massive infrastructure investments, job creation and broader economic growth be realized. In order to upgrade its digital infrastructure quickly and effectively, the United States must take appropriate incentives so that telecommunications companies can invest on a large scale and maintain healthy competition within the industry. These companies also need the freedom to work with other 5G applications to innovate and experiment with new business models. The future competitiveness of the United States will depend on that. "

Catching up requires strong leaders.

If China wants to catch up with the 5G progress of the United States, it needs a strong industrial chain leader to speed up the development of China's 5G. China Mobile is undoubtedly the leader of the three operators in terms of industry appeal and scale and volume. Moreover, China Mobile has the experience of making TD-SCDMA and TD-LTE into the mainstream standards in the world, which undoubtedly has more advantages in leading the development of 5G.

China Telecom and China Unicom will get about 3.5 GHz of each 100MHz spectrum resources, China Mobile will get about 2.6 GHz of 100MHz spectrum resources, will obviously make China's 5G commercial landing more slowly.

As we all know, the telecommunication industry is an industry with obvious scale effect. Whoever has a large scale, whose price cost is lower and whose voice is bigger. In terms of spectrum, 3.5GHz has now become the most mainstream 5G band in the world, and almost all equipment manufacturers and operators support this band. This means that the 3.5GHz band has the most extensive industry chain support, can minimize the difficulty of 5G construction, reduce the cost of equipment, to enable operators to build a 5G network in the shortest time.

Correspondingly, if China Mobile allocated the 2.6GHz band, it would be a repetition of the TD-SCDMA era. But 5G is different from TD-SCDMA. At that time, it used the best resources of China's telecommunications industry to cultivate the independent R&D capability of China's telecommunications industry and the entire industrial chain. 5G is China's leading position. Only by accelerating the development of 5G can China maintain its leading position. And the achievement of this goal undoubtedly needs to give China Mobile an opportunity to play its role.
