According to the schedule of the Ministry of Industry and Information Technology, the TD-LTE Phase I scale technical trial started in March this year ended at the end of September. The first phase of system-side test includes five parts: core network, bearer network, wireless network, terminal and security. Wireless network test is the core content of TD-LTE scale outfield test. HiSilicon, Chuangyi Video, Qualcomm, and terminal chips such as Altair, Sequans, and ZTE Microelectronics entered later stage all participated in the first-stage single-mode test.
“From the current test situation, the overall progress is relatively smooth. The technical performance and product capabilities of TD-LTE have been more comprehensively verified in the actual environment, and accumulated experience in a series of important links related to network deployment. Many problems have been solved. Of course, as a product that has just entered the scale-building and testing stage, the follow-up also needs to be continuously optimized and improved in the development, said Huang Yuhong, vice president of the China Mobile Communications Research Institute.
In December 2010, the Ministry of Industry and Information Technology approved and approved the TD-LTE scale trial overall plan. China Mobile undertakes the construction of TD-LTE scale technology trial networks and the Beijing Demo Network in Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen, and Xiamen. A total of 11 companies participated in R&D technical tests conducted in Shunyi, Beijing before the end of 2010. In the first phase of scale tests, Huawei, ZTE, Datang, Nokia Siemens, Shanghai Bell, Motorola, Ericsson, Putian, Fiberhome, Xinyou Tong also participated in all. Overall, the current stage of TD-LTE system equipment has approached the initial commercial use of FDD.
TD-LTE is in a perfect place
TD-LTE is the next-generation mobile communication technology dominated by China. It is a follow-on evolution technology of China's 3G international standard TD-SCDMA with independent intellectual property rights, featuring high transmission rate, short delay, and high spectrum efficiency. In October 2010, China’s dominant TD-LTE enhancement was successfully determined by ITU as a 4G international standard. This is a historic opportunity for China’s communications to lead the world.
“Wang Jianzhou, Chairman of the Board, once said that TD-LTE coincides with the weather, geography, and people,†said Huang Yuhong. "The so-called Tian Shi is the period in which TD-LTE and FDD LTE are in a period of common development internationally. The direction of the mobile Internet is clear, and market demand will drive technology to move forward more quickly."
The so-called geography, China's industrial capacity has grown up, the market demand for TD-LTE is there, and domestic companies have been prepared for this industry's capabilities. The successful deployment of TD-SCDMA 3G networks has not only consolidated the status of domestic companies including Huawei and ZTE in the industry chain, but also attracted the participation of more international companies.
"The so-called people and the whole industry are very supportive of the development of TD-LTE. Many international operators also have clear requirements for TD-LTE," said Huang Yuhong. It is due to the needs of international operators that China Mobile, India Bharti, Japan Softbank and many other international operators launched the GTI (TD-LTE Global Development Initiative) during the 2011 Barcelona Congress. There are now 31 operators joining GTI. More than 32 international operators have established trial networks, and 5 operators have publicly announced the construction of TD-LTE commercial networks.
Urgently clear time window
Under the leadership of the relevant ministries and commissions of the country, TD-LTE has initially formed a complete industrial chain led by Chinese companies and the participation of global mainstream companies, including systems, terminals, chips, and test instrument companies.
In 2010, China Mobile’s TD-LTE demonstration network was unveiled at the Shanghai World Expo and the Guangzhou Asian Games, and TD-LTE-based mobile high-definition conferencing and instant messaging services attracted widespread attention. At the Shenzhen Universiade in August 2011, the TD-LTE network-based instant messaging system and mobile media interview vehicles were used in the live telecast of the Universiade.
Although TD-LTE has always been advancing and possessing the advantages of good weather and time, the global promotion is still very urgent. American operator Clearwire is in a hurry. On September 15, China Mobile and Clearwire announced that they will further advance the development of TD-LTE terminal equipment. This also confirms Clearwire's willingness to incorporate TD-LTE technology into its 4G network. "Clearwire hopes to increase investors' confidence through TD-LTE. Therefore, they are more concerned about when the scale can be increased and the cost can be reduced."
Although TD-LTE already has the support of many international operators, the overall network size is small at present. Many 4G centers such as the U.S. Verizon are still in FDD LTE. There is not enough market expectation to be confused by the entire TD-LTE industry chain. If TDD can not afford scale, the resources and confidence needed for industrial development will be greatly affected.
On this issue, Professor Zeng Jianqiu of Beijing University of Posts and Telecommunications said: "In the continuous verification and testing of TD-LTE, we have solved global challenges such as co-channel interference. However, if we do not have a clear timetable for TD-LTE, If they do not really advance, they will be questioned by others.†Zeng Jianqiu even suggested that “the promotion of TD-LTE and China's leading TD-LTE enhanced 4G international standards should be included in the national strategy.â€
In fact, TD-LTE can draw experience from the promotion of FDD LTE. Verizon announced in 2009 that they will start 4G network at the end of 2010, and in the middle of 2010, it will infiltrate the construction plan covering 38 cities and 110 million people. Verizon's partners completed the construction of a commercial network within a specified period of time. At present, Verizon already has 5 LTE mobile phones, 2 PADs, 2 data cards, and 2 Mi-Fi products for users to choose.
Launched TD-LTE ≠TD-SCDMA Development Stopped
Compared with TD-SCDMA, the international situation of TD-LTE can be said to be more favorable, but the entire TDD LTE promotion process still lags behind FDD LTE. From the development of Verizon, it can be seen that FDD LTE has already introduced commercially available mobile terminals, while TD-LTE commercial terminals still have a large gap.
“We see that TD-LTE has already had a good start compared to TD-SCDMA. Now, commercial chips for TD-LTE terminals have not yet come out and can be worn out and waiting while the government is on this issue. Do not encourage or encourage others, he said, "said Chen Jinqiao, deputy chief engineer of the Institute of Telecommunications of the Ministry of Industry and Information Technology.
"Chip companies are also making active efforts. ZTE will launch TD-SCDMA/TD-LTE multi-mode chips, and the world's first TD-LTE/TD-SCDMA/GSM multi-mode mobile phone prototype will also be unveiled during the Shenzhen Universiade. Chip makers such as Spreadtrum and Remail are also developing TD-SCDMA/TD-LTE multimode chips,†said Huang Yuhong. “This shows that everyone should reach a consensus that advancing TD-LTE does not mean that TD-SCDMA will not develop. ."
The gradual advancement of TD-LTE has attracted more international companies to join this camp. On the one hand, it has built up a more complete and robust industrial chain. On the other hand, it also allows us to pay more attention to the international competitiveness of national industries.
"Through the TD-LTE scale-up technology test, we have seen that domestic companies have done a good job in TD-LTE as well. Taking China's relatively weak chip as an example, we have seen very good domestic companies. Therefore, we are not We are worried that Chinese companies will be attacked by the international community."
TD-LTE has indeed opened a door for China's industry. Huawei and Poland Aero2 signed a commercial network contract last November, and launched the LTE TDD/FDD converged commercial network for the latter. In the Swedish LTE TDD/FDD converged commercial network, which is in cooperation with Hi3G, HiChina has adopted the ZTE SDR platform and a unified core network and network management platform to implement the TDD/FDD common mode network. On May 4th this year, ZTE Corporation passed 100%. The first phase of the Swedish Hi3G acceptance test.
The two most representative companies in China's telecommunications industry recently jointly seized the world’s largest TD-LTE commercial network contract and built a TD-LTE network for Japan’s Softbank covering 90% of Japan’s population and region. Datang Mobile has also started TD-LTE trial network related work in Europe and Africa.
In terms of the internationalization of TD-LTE, China Mobile has actively played its unique role as an operator. "Through leading GTI (Global Development Initiative for TD-LTE), we have built a platform for international operators to jointly promote the development of TD-LTE, and at the same time, they have also tempered the international capabilities of Chinese companies." Huang Yuhong said, "In GTI, China Mobile actively shares TD-LTE's information and experience with more international partners to jointly solve various key issues and is committed to making TD-LTE bigger and stronger together with the entire industry chain."
“From the current test situation, the overall progress is relatively smooth.
