During the Spring Festival, many people greet the greetings when they are "4G." 2013, 4G opens; and there is no doubt that 2014 will become the assault year for China's 4G development. The consensus of the industry is that under the unified standard of LTE, the common integration of FDD and TDD modes has become LTE. An important factor in accelerating development.
Assault
Several data reflect that China's 4G construction will advance by leaps and bounds in 2014. Li Yue, president of China Mobile, said that China Mobile plans to sell more than 100 million LTE TDD terminals in 2014; Xu Gang, deputy general manager of China Mobile's marketing department, said at the "Global LTE Operation Development Summit Forum" held on February 18, by the end of the year. China Mobile's 4G commercial city will reach 344; also in the forum, Qian Jinqun, deputy secretary general of China Communications Enterprise Association, said, "It is expected that China's 4G network will become the world's leading 4G network."
Xu Gang, deputy general manager of China Mobile's marketing department, believes that "the development of the industrial chain is much faster than we think." He said that more than 27 4G mobile phones were listed in the first quarter of this year, covering the major terminal manufacturers and equipment vendors. This speed far exceeds the development speed of 3G. According to incomplete statistics, the 4G mobile phones released by China Mobile are: Samsung Galaxy Note 3 mobile version, HTC One Max mobile version, Sony Xperia Z1 L39t, iPhone 5S/5C, nubia Z5S LTE, vivo Xplay 3S and Huawei G716, etc. Most of them have built-in Snapdragon processors and support LTE TDD/LTE FDD/3G multimode multi-frequency.
The most advanced network, faster than the imagination, is the key word for the development of China's LTE. Regarding the leading network, Li Yue, the president of China Mobile, said that in the 2G/3G era, it can only meet the "pass" and "have", and the 4G era can achieve "good" and "fine". Ms. Huang Yuhong, vice president of China Mobile Research Institute, also said, “Every manufacturer does not want to engage in an industry line alone. It only does TDD or only FDD, because only by making it a unified platform and a unified product can it be maximized. Economic benefits." Regarding the speed of development, Qian Jinqun, deputy secretary-general of the China Association of Communications Enterprises, said, "The world's leading operators have focused on and actively promoted LTE as a universal standard to support FDD and TDD models. Mobile phone manufacturers can no longer Limited by the differences in technology and standards at home and abroad, it can enter the international market quickly and seamlessly."
Common benefit
The consensus reached by the industry is that the "surge" is largely due to the versatility and uniformity of the LTE standard. Wen Ke, Director of the Communication Development Department of the Ministry of Industry and Information Technology, said at the "Global LTE Operation Development Summit Forum" that "the integration of FDD and TDD is a very promising topic," he said. "The TDD and FDD multimode terminal routes are gradually being internationally The major operating companies have recognized that LTE and FDD converged networking is conducive to meeting the rapid growth of data services."
Wang Xiang, senior vice president of Qualcomm and president of Greater China, said on many occasions that in the 2G era, domestic mobile phone companies are hard to make achievements in the high-end field, while the LTE era is rapidly moving toward high-end and international markets. He believes that "LTE technology is a single standard in the world. It has two different duplex modes to adapt to different regions and market needs. The essential difference between TDD and FDD is not large, so building a global unified industrial chain will be very easily."
Lanneri, director of mobile broadband solutions at Ericsson's Northeast Asia region, also said, "Operators require standards organizations to minimize the difference between the two, so that FDD and TDD can achieve converged network construction. This goal has been achieved, and future TDD And FDD will be a unified platform."
In terms of operational practices, Japanese operator Softbank conducted an early TDD/FDD hybrid networking attempt and developed well. Ted Matsumoto, a special consultant for Softbank Mobile CEO, believes that TDD and FDD are 3GPP common standards and have the same ecosystem. He said that with the support of multi-mode processors, "Softbank decided that all terminals in the future must support FDD and TDD."
In China, China Mobile has already built a hybrid FDD/TDD network in Hong Kong. Xu Gang, deputy general manager of China Mobile's marketing department, said that TD-LTE (LTE TDD) and FDD LTE are both 4G. There is no difference between technology and specifications. The only difference is spectrum planning. From an engineering perspective, Zhao Hui, director of project management at Qualcomm Technologies and director of network deployment technical support for Greater China, said that LTE is actually a global single standard, including FDD/TDD two duplex modes, mainly for certain Region and country or certain specific scenarios. The technical differences between TDD and FDD are very small and basically the same. "From my engineering point of view, the main difference is that there are some small differences in the physical layer, but most other levels are almost identical." He said that Qualcomm has officially released the fourth-generation LTE chip solution to date. All formats, such as FDD/TDD, support global carrier aggregation deployments of up to 40 MHz on LTE TDD and FDD Cat.6 networks.
In summary, a more unified standard will support the rapid development of 4G LTE. As the latest report from Strategy AnalyTIcs, a market research and consulting organization, “LTE TDD and FDD systems share the same network architecture and protocol stack, and the key technologies and core processes of the physical layer are exactly the same. At the beginning of LTE design. 3GPP will realize a single air interface technology supporting both FDD and TDD as a very clear system requirement of LTE, and hope to provide greater economic scale for both duplex systems." Report, "Converged LTE TDD And FDD is becoming a booster for data rates and network capacity, and unified standards are providing a solid foundation for LTE's global economy."
