The World Mobile Communications Conference just concluded in Barcelona. At the meeting, China Mobile President Li Yue sent an exciting message to the global communications industry. China Mobile will expand the TD-LTE scale test this year, based on the original 6 test cities. Three cities will be added-Beijing, Tianjin, Qingdao, and the total number of base stations will also be expanded from 2,000 in the first phase to 20,000.
This year is just the beginning. According to the 3-year deployment of the TD-LTE Global Development Initiative (GTI), by 2014, more than 500,000 TD-LTE base stations will be built globally, covering more than 2 billion people, which is better than ABI Research (consulting company). ) Earlier predictions-at least 500,000 TD-LTE base stations were built at the end of 2016, a full two years ahead of schedule. This plan has far exceeded the industry's expectations. Under the encouragement of LTE global commercial deployment, TD-LTE has already advanced at full speed, and enterprises in the industry chain need to readjust the timetable to keep pace with the accelerated development of TD-LTE.
Industry mobilization at the beginning of the year <br> As for the news that China Mobile will expand the scale of TD-LTE construction this year, mainstream companies in the TD-LTE industry chain have been known as early as this year. On January 5, China Mobile held a TD-LTE symposium in its Innovation Building. TD Industry Alliance Secretary Yang Hua chaired the meeting and delivered a speech. The relevant leaders of the State Council Research Office, Wei Bing, deputy general manager of China Mobile Technology Department, China Mobile Wang Xiaoyun, vice president of the Academy, Wang Zhiqin, deputy chief engineer of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, Jiang Yuan, vice president of China Mobile Design Institute, and Datang, ZTE, Huawei, Nokia Siemens Networks, Ericsson, Samsung, Lenovo, Yulong, Qualcomm, Leaders of TD core enterprises such as Galaxy Highlights and Chuangyi Video Communication attended the meeting. At the seminar, Yang Hua, Wei Bing, and Wang Zhiqin gave very clear answers to questions such as the trial commercial time of TD-LTE.
This meeting is undoubtedly an industry mobilization meeting.
After this meeting, the focus of industry chain enterprises quickly shifted to trial commercial use. "This year's work is very heavy. On the one hand, we must do the second phase of TD-LTE testing, on the other hand, we must prepare for trial commercial use." Cai Yuemin, chief engineer of Datang Mobile's LTE product line, accepted the "China Electronics News" The reporter said in an exclusive interview, "Datang also developed a new product for the expansion of TD-LTE this year. From last year, a baseband board supports 20M8 antenna carrier integration to a baseband board supports three 20M carriers. The integration is higher. Will reduce costs and apply to large-scale networking. "Not only Datang, other system companies are also doing the same pre-commercial preparations.
Need low-cost and fast network construction <br> In 2012, China Mobile wanted to expand the scale of TD-LTE base stations to more than 20,000. Considering that the TD-LTE operating frequency band is relatively high and the coverage area is shrinking, its scale is basically the same as the scale of the 14,000 base station trial construction of TD-SCDMA 10 city launched by China Mobile in 2008. This is the "big training" before the commercial use of TD-LTE. The first to be tested is the system equipment manufacturer, including the commercialization level of the product, network planning, optimization capabilities, and business support capabilities, etc., to accelerate the development of TD in China Mobile -After LTE, the rapid network construction capabilities of system manufacturers have also become very important.
"Smooth evolution strategy is the key to realizing large-scale rapid network construction of TD-LTE." Cai Yuemin said. Improving the smooth upgrade of TD-SCDMA / TD-LTE dual-mode support from TD-SCDMA to TD-LTE is also the focus of Datang Mobile this year. Datang Mobile has already conducted a small-scale verification in Nanjing's scale test network as planned , Both RRU (radio frequency unit) and BBU (baseband unit) that implement the same base station support dual mode.
"The site construction and sky construction of the TD-LTE pre-commercial or commercial network in the future are two important factors that affect the project's difficulty, construction cost and project schedule." Eric Chen, Wireless Product Expert, Product Management Department, Ericsson China and Northeast Asia In an exclusive interview with a reporter from China Electronics News, the doctor said, "For China Mobile, we suggest that TD-LTE can share the same site with TD-SCDMA or GSM. The benefits of the latter are more The site resources of the site are more flexible. "Chen Ming said," According to our analysis, these two co-site methods can save about 70% of the cost of TD-LTE site construction compared with the new site. "
Terminal strategy is the most critical <br> Terminal is a crucial part of industrial development, and the design of terminal chip is the core.
The terminals that entered the first phase of TD-LTE field testing were mainly single-mode chips. Hisilicon, Chuangyi Video, Qualcomm, Aite, ZTE Microelectronics, Seiken, SingPost, STMicroelectronics, Spreadtrum have corresponding solution. The second phase of the test focuses on interoperability of multi-mode terminals, mainly TD-LTE / TD-SCDMA multi-mode.
There are currently only three chip vendors shortlisted for the second phase of MTNET testing, namely Lianxin Technology, Chuangyi Video, and ZTE Microelectronics. Among them, Lianxin Technology's TD-LTE / TD-SCDMA dual-mode solution DTIvy1760 is one of the few single-chip dual-mode solutions in the industry. The data card product LC5760 based on this solution has also participated in the test and can already meet TD-LTE networking The requirements of various indicators, basic performance or early commercial requirements. However, from the perspective of the terminal as a whole, the multi-mode test terminal that most companies can provide will also be dominated by dual chips.
"In 2012, the TD-LTE industry should continue to increase investment, the focus of which is to strengthen the development of multimode chips." Yang Hua, Secretary General of the TD Industry Alliance, said in an exclusive interview with a reporter from China Electronics News, "The future is multimode In the world of terminals, HiSilicon and Chuangyi Video have developed faster in TD-LTE single mode, but in the future, the ability of international companies to increase TDD in FDD mode is much stronger than the ability of domestic companies to increase FDD in TDD technology. The speed will also be much faster, which is determined by the original foundation of the enterprise. "
In view of the current status of TD-LTE terminal development, China Mobile also has various considerations for terminal development. An industry source close to TD-LTE testing told reporters that this aspect must take into account the maturity of LTE terminal chips, and on the other hand, the positioning and marketing strategies of TD-LTE. According to the report of Wang Zhiqin, chairman of the 3G and broadband wireless field of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, LTE is currently mostly a data terminal, and the LTE module of multi-mode mobile phones is only used for data services, and voice solutions are not yet mature. Moreover, most of the current terminal chips are based on the 45nm process. The LTE module consumes about 500mA, which is significantly higher than the power consumption of HSPA about 300mA. The 28nm chip suitable for smart phones is expected to be put on the market after 2013.
