subject: China Mobile Td [print this page] HC Communication Network Platform through the Expo, organized by the International Telecommunication Union, TD Industry Alliance and China Mobile Host of "TD International Development Summit" on May 17 the United Nations Pavilion at Expo held.
At the end of March, the domestic TD users reached 7.69 million. The world's 4.7 billion Mobile Users 3G Users only 15% of the domestic market potential in particular.
Addition to the TD-LTE Expo business presentations, Africa and China Taiwan Area TD-LTE test network will also have opened for the next large-scale development of TDD technology at home and abroad to lay a strong foundation.
Operators join forces in the industrial chain for the TD-S CDMA Network 2010 200 000 base stations, and built the world's largest 3G network goals go all out, China Mobile Vice President Sha Yuejia published by the Forum of China Mobile TD-LTE international strategy, and proposed the "resources" and " confidence "is the internationalization of TD-LTE two key.
1GHz Following the scarcity of frequency resources
Following the ITU Deputy Secretary-General Zhao Houlin confidently said that this year in October to finalize the 4G ITU standard TD-LTE-Advanced the possibility to win more than 70%, China Mobile Research Institute Vice Dean Wang Xiaoyun, said frankly at the forum, for the next step in the evolution of TD-SCDMA, while providing comprehensive support, TD-LTE development in the internationalization of the frequency resources are still faced with a series of challenges. So, to win more international spectrum resources, have more confidence in the industry chain of China's mobile joint international campaign "important foothold."
For more global TDD frequency resources for the "very" important, Diachronic explanation, high-quality TD-LTE TDD resource is an important guarantee for international development, TDD is the lack of global frequency resources is a fact, global TDD FDD frequency resources within a 5.5-fold, still more obvious disadvantages. "High frequency on TD-LTE product development and network coverage, the cost of investment have brought many problems. In fact, each technology are fighting for high-quality spectrum, which is more suitable for the following 1GHz, but not the TD-LTE a resource. "
The international level, on the one hand IT U is promoting more of the TDD spectrum for operators worldwide are using the other hand, the low frequency of 700MHz spectrum has become a popular band, by many operators concerned. Wang Xiaoyun said for the ITU, domestic operators, the relevant units as well as the Ministry of Industry and Technology Division are to promote the TDD frequency band to do a considerable increase in the work of various international occasions, China Mobile also called for TDD spectrum allocation more to support international development.
In the "confidence" in the interpretation, the Diachronic said how operators around the world are confident TDD technology, which involves several key factors, one of which is to build a complete industrial chain end to end; Second, is to promote the TDD, FDD synchronous development, because only in parallel to gain a competitive edge, including the standardization of synchronization, product synchronization, test synchronization, and synchronization of the terminal authentication, etc.; the third operator to joint TD-SCDMA industry chain in the original Based on the experience of using the international mode of operation to a leading international organizations TD-LTE work. "China Mobile, under the unified leadership of the Ministry of Industry, together with the TD Industry Alliance, a large international operation."
Any international time standard, there are many international organizations to promote, involving requirements, standards, testing and other aspects. To this end, China Mobile has set up a TD-LTE International to advance the project, that all international organizations in promoting the advancement of the work themselves with the FDDLTE, we must simultaneously work to promote TD-LTE's, to truly TDD technology to the international .
Next: Three city-wide network coverage verification capability
TD-LTE test in three phases, the current technology has entered the pilot phase.
