TD-LTE global break

TD-LTE is still the near-term focus: China Mobile has set up a TD-LTE demonstration network at the Guangzhou Asian Games to provide 10 quasi 4G mobile broadband experiences such as 3D video on demand and TD-LTE wireless telepresence to viewers; November 17 to On the 18th, at the 2010 Mobile Communications Asia Conference held in Hong Kong, China, China Mobile and other companies further demonstrated TD-LTE technologies and applications, discussing the TD-LTE industry status, application scenarios, terminal trends, and future-oriented convergence. And more exciting is that on November 19, the Polish operator Aero2 announced that it will deploy the world's first TD-LTE network, which is expected to begin operations in early 2011.

The development of TD-LTE in China will move from the experimental stage of technology to the trial stage of multi-city scale. At the same time, with the advantages of high spectrum utilization rate and low delay, TD-LTE is also gaining more and more support from operators in the international community. Under this trend, how can the industry chain seize the opportunity of TD-LTE? How can Chinese companies exert their advantages when their global counterparts compete?

In fact, Polish mobile operator Aero2 has launched a commercial network of LTE FDD in September this year. Since it purchased two other Polish operators this year, it chose Huawei's common platform solution for spectrum utilization considerations. TD-LTE commercial network deployment.

Previously there were predictions that Japan and India might be the earliest countries to deploy TD-LTE commercial networks before China, and now it seems that there are other operators interested in TD-LTE, China's leading quasi-4G technology. Huang Xiaoqing, president of the China Mobile Communications Research Institute, recently said at the “International Forum for a New Generation of Broadband Wireless Mobile Communications” sponsored by the Institute of Telecommunications of the Ministry of Industry and Information Technology that 11 TD-LTE trial networks have been established in the world and 8 The trial network is also planned to be opened between 2010 and 2011. It is reported that China Mobile has established formal partnerships with eight international operators to jointly promote the healthy development of the TD-LTE industry.

At the end of September, China Mobile conducted a survey on more than 300 industry chain representatives from around the world on TD-LTE development issues at a TD-LTE network conference. 54% of them believe that in the international market other than China, TD- LTE will be selected by countries that have TDD frequency auctions. Huang Xiaoqing stated that after one year of development, especially after the scale demonstration at the Shanghai World Expo, the global acceptance of TD-LTE has greatly improved compared with 2009.

The frequency spectrum determines that the global industry’s attention to TD-LTE will not only be due to the good performance of the China Demo Network, but also to the judgment of mobile broadband development.

"In the next 10 years, the number of mobile broadband users of natural persons will reach 5 billion, and the number of non-natural users will reach more than 60 billion, so the global mobile traffic will increase by 500 times." Lu Xingang, director of product lines for Huawei's CDMA&WIMAX&TD product line, points to China "News" reporter said, "In this way, wireless spectrum and wireless sites will become scarce resources."

Lu Xingang believes that in the 2G era, the world will mainly use 900M and 1800M frequency bands for mobile access, and in the future, all frequency bands will be used as wireless broadband access. "The U.S. government is even prepared to take out some of the white bands below 700M that were originally used for broadcasting and television and use it for future wireless broadband research," he said. Lu Xingang stated that Huawei believes that in the era of mobile broadband in the future, technological competition will give rise to competition in the spectrum. Whoever has the spectrum will have the initiative.

TDD technology is favored by the world due to its use of asymmetric frequency bands. Huang Xiaoqing told reporters that the prices of TDD bands that frequently encountered bids in spectrum auctions three years ago have soared this year. The recent 2.3 GHz band auction conducted by India is an example. It is understood that more than a dozen countries around the world have issued TDD spectrum, such as the United States in the 2.5GHz band, India in the 2.3GHz band, some countries in Western Europe and Northern Europe this year began to issue 2.6GHz TDD band, Vodafone, Deutsche Telekom, France Telecom All of them are concerned about TDD spectrum and hope to supplement TD-LTE to meet the rapid growth of asymmetric services. "This shows that the era of TD-LTE has arrived." Huang Xiaoqing said.

The telecommunications giant gathers "Many global operators have shown great interest in TD-LTE technology. These interests, we feel mainly due to the existence of TDD spectrum, operators seeking a most widely supported mainstream technology, TD- LTE is in the limelight, and we believe that TD-LTE will have more opportunities for development in the world next time.” At a recent Chinese media meeting, Erik Ekudden, vice president of R&D at the Ericsson Group, told reporters. He said that Ericsson is making active efforts to seize more TD-LTE opportunities with its own product capabilities.

"TDD technology will have very broad development prospects in the future of mobile communications, especially mobile broadband, and Huawei is optimistic about TDD," Lu Xingang also said.

It is because of the bullishness of major companies that TD-LTE converges almost all of the communications power of the world. In terms of TD-SCDMA technology, there are efforts made by industrial clusters dominated by Chinese companies; in WiMAX, mainly US companies; and in FDD LTE, there are old telecommunication giants based mainly on European companies. Now these forces are brought together to form a global industrial cluster. This will facilitate the development of TD-LTE and will also create greater competition. This poses a huge challenge for Chinese companies, especially those starting from TD-SCDMA technology.

Taking the terminal chip as an example, the earliest TD-LTE terminal chip solution launched was Huawei Hass and Chuangyi Video, followed by Sequance from WiMAX chips to TD-LTE in France. Not too long ago, Broadcom Corporation announced that it had acquired Beceem Communications, a 4G chip manufacturer, for $316 million in cash, aiming at LTE. At the same time, Qualcomm is also an important participant in the TD-LTE field. With the competition of these big-name chip companies, can China's relatively weak chip companies still have room for survival?

Chinese Business Opportunity “I have confidence to say that in the era of TD-LTE, China’s manufacturing industry can definitely reach 50% market share,” Huang Xiaoqing said. He said that the early demonstration network of TD-LTE (including the Shanghai World Expo and the TD-LTE demonstration network of the Guangzhou Asian Games) was built by Chinese enterprises. His and Hehuangyi Video, which can propose terminal solutions at the earliest, are also Chinese enterprises. It is time to launch truly commercially available products and applications so that interested operators can see TD-LTE products that are easy to use and inexpensive, and naturally there will be huge business opportunities. “Chinese companies have great opportunities because WiMAX operators or new operators also need TD-SCDMA to provide quality-assured voice services,” he said.

At the same time, experts also pointed out that it is still necessary to vigorously develop TD-SCDMA and further handle the relationship between the coordinated development of TD-LTE and TD-SCDMA. Chen Shanzhi, Vice President of Datang Telecom Technology Industry Group believes that the major technological innovations of LTE at the physical layer and core network make it necessary for a large number of authentication and technical improvements in cellular networking, especially multi-cell networking and mobile links. In terms of the terminal, for the high rate of LTE, the data card needs a 65-nm integrated circuit process, and the mobile phone needs a 28-nm process to meet the market needs in terms of power consumption and cost. The current 28-nanometer process is not yet mature, so it is not until 2013 or 2014 that TD-LTE handsets will emerge. “So now we must unswervingly promote the commercialization of TD-SCDMA scale, cultivate the habits of users' mobile internet, nurture applications, and explore business models. At the same time, we must vigorously develop and strengthen the TD-SCDMA industry chain for the future industrialization of TD-LTE. Lay the foundation for development," said Chen Shanzhi.

"From 1G to 2G to 3G, from the perspective of the development of the mobile communications industry, the objective law determines that the time period from standardization to commercialization is insurmountable. Of course, as technology advances, each phase will be relatively shortened. We must follow the objective laws of industrial development and actively, orderly and steadily advance technological trials such as TD-LTE outfield scale verification,” said Chen Shanzhi.
