Yang Hua, Secretary General of the TD Industry Alliance, said at the "ICT China · 2013 High-level Forum" held on September 26: "TD-LTE and FDD-LTE technologies and industry maturity are 'basically equivalent', but due to the lack of benchmark operators The scale of commercial use is driving, and the commercial driving force is slightly insufficient. "TD-LTE is China's core competitiveness in the field of mobile Internet. In response to the grabbing point layout of developed countries in the field of mobile Internet, the commercial process of TD-LTE should be accelerated The core competitiveness in the development of mobile Internet has transformed into a first-mover advantage. The actual progress of TD-LTE technology in China will affect the choice of future technical standards by international operators, and then affect the success and breakthrough of TD-LTE internationalization. At present, the two basic conditions for the commercialization of TD-LTE technology have been met: the domestic TD-LTE base station construction scale and the maturity of industrial development have reached the conditions to support the commercialization of TD-LTE technology. In addition, the commercial scale of TD-LTE technology in the international market is also steadily increasing. Both the internal and external market environments indicate that the time has come for domestic TD-LTE to be commercialized. TD-LTE network construction has taken shape At present, with the promotion of China Mobile, TD-LTE trial networks have been built in 15 cities. In 2013, with the advancement of China's "Double Hundred Plan", the construction of TD-LTE network accelerated. The bidding for the main equipment of TD-LTE network has been basically completed. The construction of 200,000 network base stations in 100 cities has also been successfully launched. Important cities The main urban area is continuously covered, and the data hotspot areas of the main urban areas of other cities are covered. In October, the Ministry of Industry and Information Technology officially approved that China Mobile would expand the TD-LTE scale test to 326 cities nationwide. In addition, existing TD-SCDMA network resources are also potential resources for TD-LTE large-scale network construction. Since the issuance of 3G licenses in 2009, the construction of more than 220,000 base stations of China's independent innovation 3G communication technology standard (TD-SCDMA) has been achieved, and the scale of the TD-SCDMA Phase 6 network in the second half of this year is also very large. The number of TD-SCDMA base stations will reach 300,000, and 3G communication networks will cover the whole country. It should be pointed out that, at the early stage of TD-SCDMA system construction, China Mobile fully considered the need for a smooth evolution to TD-LTE. The dual-mode base station shares antennas and network equipment, so as to make full use of the current TD-SCDMA site to achieve a smooth evolution to TD-LTE, effectively save valuable site space and resources, and achieve rapid and convenient network upgrades while protecting the existing maximum With investment, the network construction cycle has also been greatly shortened. Taking the construction of China Mobile's Ningbo TD-LTE trial network constructed by Datang Mobile as an example, the feasibility of the TD-SCDMA / TD-LTE dual-mode smooth evolution solution has also been fully proved. The performance indicators and other aspects have shown significant advantages, and are fully prepared for the subsequent large-scale rapid deployment of the next TD-LTE network. According to third-party data, China Mobile has built a total of about 450,000 base stations on the 3G network (as of May 2013), and before the official license issuance and commercial use, the 4G base stations built reached the total number of base stations in the 3G era. Half. Recently, China Telecom has also approved the construction of the TD-LTE test network, and has completed the first phase of equipment bidding. China Unicom also started planning 4G bidding, including about 10,000 TD-LTE base stations. The three major operators working together to promote TD-LTE network construction will further accelerate the scale of TD-LTE network construction, laying a solid foundation for TD-LTE to enter the commercial market. TD-LTE mobile phone market launch breaks the terminal bottleneck After more than three years of expansion and cooperation, TD-LTE has been widely recognized and supported by domestic and international operators and many international organizations. Currently, TD-LTE includes Datang, Huawei, ZTE, Nokia Siemens Networks, Ericsson, Alcatel-Lucent, etc. The major global system manufacturers have all supported TD-LTE technology, and the TD-LTE industry chain has gradually improved and matured. The development of chips and terminals in the weak link of the TD-LTE industry chain is even more encouraging. As of the third quarter of this year, a total of 14 chip manufacturers worldwide have successfully developed TD-LTE samples and commercial chips. As the TD-LTE industry matures and is commercialized, TD-LTE chips and terminals need to further improve performance in the future. LTE chips will gradually evolve to 28 nanometers to provide a better user experience. Datang, as the largest integrated circuit enterprise in China, faces major applications in the communications industry and implements the "4G + 28nm" project. The 28nm chip independently developed will achieve mass production in 2014, fully supporting TD-LTE 4G large-scale commercial and mobile The rapid development of the Internet has realized benign interaction, transformation and upgrading of the industry. The speed of terminal development has always been a key link in the development of the TD-LTE industry. As of the third quarter of this year, 80 manufacturers worldwide have launched 296 TD-LTE terminals, an increase of 54 compared with the second quarter. 14 manufacturers have launched 30 TD-LTE smart phones, and more than 20 TD-LTE mobile phones will be launched from the end of 2013 to the beginning of 2014. As of the end of September, 12 TD-LTE terminals (including 11 4G mobile phones and 1 4G data terminal) had obtained the network trial certificate from the Ministry of Industry and Information Technology. The bottleneck of the terminal where TD-LTE entered commercial use was broken. It is reported that Beijing Mobile has officially launched 4G mobile phones recently, and this time it launched two smartphones supporting TD-LTE network. TD-LTE international market is recognized for commercial use As the mainstream technology in the global mobile broadband era, TD-LTE has not only become an international standard, but also has been widely recognized by industries such as international manufacturing and operations. In 2013, the global TD-LTE market and industry growth have made considerable progress. According to statistics from DIGITIMES Research, as of the third quarter of 2013, 17 countries and 21 operators worldwide have invested in TD-LTE network commercialization services, and the number of base stations reached 50,000, and the number of users is about 4.6 million, compared with 2012 During the same period, the above-mentioned industrial data all showed multiple growth. In addition, a few days ago, Sprint, a well-known US operator, decided to use TD-LTE technology to expand its original network. This network construction is the first time TD-LTE technology has been deployed nationwide in North America. Sprint will carry increasing data traffic through TD-LTE. With the announcement of Sprint's adoption of TD-LTE, it undoubtedly paved the way for the global development of TD-LTE. As a technology with a strong Chinese color label, TD-LTE can be built on a large scale throughout the United States, which is undoubtedly a major breakthrough for the current global TD-LTE commercial network scale. This also breaks the status quo in the communications industry where China can only introduce technology from other countries, while Chinese technology is excluded from the international market. In a country such as the United States, which is very important for its own communication security and technology patents, TD-LTE technology can be entered, which once again strengthens the confidence of the international market to choose TD-LTE technology. TD-LTE is of great significance to China's entire communications industry. In the 2G era, our development starting point is late. In the 3G and post-3G era, we finally have an opportunity to start with the world's communications industry. TD-LTE is expected to further develop on the basis of TD-SCDMA's "international standard". Realize the "international application" of China's leading technology, and realize the great leap from "following, breaking through" to "leading" in China's communications industry. At present, the domestic TD-LTE technology is mature, the scale of network construction is available, the bottleneck of the industrial chain has been broken, and the commercialization conditions of TD-LTE technology are available; in addition, it is understood that the actual subscription users of China Mobile are expected to exceed 100,000, the domestic market Demand is strong; meanwhile, TD-LTE commercialization has blossomed everywhere in the international market. Whether considering the domestic market conditions or weighing the international market environment, the domestic TD-LTE commercialization is not waiting for me!
