China Mobile will jointly launch multiple TD-LTE multimode dual standby terminals with manufacturers

According to the news on November 21st, Cao Shumin, the dean of the Institute of Telecommunication Research of the Ministry of Industry and Information Technology, recently attended the "2011 Cross-Strait TDD Broadband Mobile Technology Development and Cooperation Summit Forum" revealed that four chip or terminal manufacturers plan to launch TD-LTE multimode by the end of this year Data card or dual standby mobile phone.

This means that while the rapid advancement of TD-LTE scale technology trials, the key link in this field, the R & D and production of terminals, has made substantial progress. In the first phase of the TD-LTE scale test, the single-mode terminal is the main test.

It is understood that after the Ministry of Industry and Information Technology has approved the overall plan of TD-LTE scale technology test, China Mobile has joined the industry chain related manufacturers to build TD-LTE scale in six cities of Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen and Xiamen from the beginning of this year Testnet.

It is reported that China Mobile has invested more than 600 million yuan to build a TD-LTE scale test network of more than 850 base stations in the above six cities, and completed TD-LTE scale tests with 7 network equipment manufacturers and 3 chip manufacturers The first stage of testing work.

According to the plan, China Mobile will complete the second phase of the TD-LTE scale test by the end of June 2012, and will build 1-2 million TD-LTE base stations during this period.

Cao Shumin introduced that there are currently 8 system manufacturers (Huawei, Nokia Siemens Networks, ZTE, Datang, Shanghai Bell, Motorola, Ericsson, Fiberhome) have completed TD-LTE testing, and there are 3 other system manufacturers (New Post, Putian, Samsung ) Testing is in progress. In addition, 6 chip manufacturers (Huawei Hisilicon, Chuangyi Video, Qualcomm, Altair, ZTE Microelectronics, Sequans) have completed the test, and there are 4 other chip manufacturers (Lianxin, Chongxin, Branch, Spreadtrum, STMicroelectronics Ericsson )testing.

It is reported that after completing the first phase of the TD-LTE single-mode chip data card test of the scale test network, China Mobile will complete the multi-mode data card and dual standby mobile phone test in the second phase. At present, China Mobile has begun to purchase TD-LTE terminals in batches for the second phase of testing.

According to Cao Shumin, there are two stages in the development of TD-LTE multimode terminals and chips. One is the multimode dual standby (single chip or dual chip) solution that can be introduced quickly; the other is the future development direction, that is, more Mode single standby (single chip) solution.

Among them, TD-LTE single-mode chips and TD-SCDMA / GSM commercial chips are combined to form a dual-chip multi-mode terminal. At present, the TD-LTE multimode chips provided by the three manufacturers have entered the commissioning test conducted by the Ministry of Industry and Information Technology. The four chip or terminal manufacturers plan to provide TD-LTE multimode data cards or dual standby mobile phones in the fourth quarter of this year.

The multi-mode single standby solution uses a 40-nanometer process and supports at least TD-LTE / TD-SCDMA / GSM tri-mode. According to Cao Shumin, seven chip manufacturers will provide single-chip multi-mode terminals in 2012, and some chip manufacturers plan to provide them at the end of 2012 or 2013.

According to China Mobile's plan for TD-LTE terminals, the R & D and production of commercial data cards will be completed in 2011, and mobile phone prototypes will be launched; in 2012, the data card will reach commercial scale and mobile phones will reach commercial level; in 2013, data cards and mobile phones Reached a large-scale commercial level.

In fact, the above plan has achieved a major breakthrough in 2011. According to Huang Yuhong, vice president of China Mobile Research Institute, two data cards of Huawei and ZTE have achieved commercial supply level, including multi-mode dual standby prototype (ZTE, Coolpad), data card (Altair, Qualcomm, Chuangyi More than 35 types of terminal products including videoconferencing, HiSilicon, Samsung, Sequans), tablet computers and netbooks (Guangda, Nokia), CPE (HiSilicon, Chuangyi Video), etc. have been developed and sampled.
