At the International Telecommunication Union 2012 World Telecom Exhibition held in Dubai, UAE yesterday, China officially announced that all 190MHz frequency resources in the 2.6GHz band will be planned as TDD spectrum (the industry also commonly calls this band D-band), which means that China Mobile will operate in the future. 4G network TD-LTE uses this frequency band.
In this regard, Zhao Jibin, vice president of China Mobile, said in an exclusive interview with Tencent Technology, "The purpose of TD-LTE spectrum planning is to be able to commercialize 4G in China as soon as possible. At present, China Mobile will have 20,000 TD-LTE base stations this year, and the network Coverage will reach 13 cities, and the existing 200,000 TD-SCDMA base stations can also be smoothly transitioned to TD-LTE. By 2013, there will be more than 200,000 TD-LTE base stations and more than 100 experimental cities. "
He also said, "In the face of the progress of TD-LTE industrialization, TD-LTE has successfully established an international end-to-end industrial chain led by Chinese companies and widely supported by the world. System equipment has moved from laboratories to large-scale applications. Commercial capabilities have been significantly enhanced. "
As of now, 10 system manufacturers have released TD-LTE products, 20 chip manufacturers have launched TD-LTE products, and more than 20 chip manufacturers have already made clear road signs. At the same time, the test instrument system has also been initially established. More than 20 manufacturers have provided more than 50 TD-LTE test instrumentation equipment.
Regarding the progress of TD-LTE internationalization, he also said, "As of September 2012, there are already 11 operators in Saudi Arabia, Japan, Brazil, the United Kingdom, India, Australia, Poland, Oman, Russia and other countries worldwide Twelve commercial TD-LTE services were opened, 24 operators signed a total of 31 TD-LTE commercial contracts, more than 29 operators specified TD-LTE commercial plans, and more than 53 TD-LTE experimental networks have been opened worldwide .TD-LTE has initially laid a market foundation for the realization of global deployment and application. "
Speaking of the TD-LTE commercial process schedule, Zhao Jibin did not disclose. He once again said, "The release of spectrum planning shows that commercial technology is no longer a problem. The follow-up should be close to all links of the industry chain, such as terminals and chips." Some foreign investment banks predict that China Mobile may be issued a 4G license as early as next year. The second half.
As a shortcoming of the TD / TD-LTE industry chain, its terminal development has always lagged behind base stations, but this year, the launch of TD-LTE terminals has begun to accelerate. For TD-LTE terminals, the current product form needs to be expanded from data card form to other mobile terminals as soon as possible.
According to the reporter's understanding on the scene, this exhibition attracted many guests from international operators, system, terminal chip, test instrument manufacturers, and international industrial organizations. Among them, at the fifth GTI seminar hosted by China Mobile and the TD-LTE Global Development Initiative GTI, the first demonstration of the world's first support of 5 modes (LTE TDD / LTE FDD / TD-SCDMA / WCDMA / GSM) (Band 38/39/40/41/3/7/34/1/2/5/8), multi-mode multi-band Hotspot product prototype with global roaming capabilities. In particular, the launch of multi-mode multi-band data products is a key to the global development of TD-LTE, laying the foundation for the global deployment and application of TD-LTE and global roaming.
That is to say, if the user has such a multi-mode mobile phone, in the future when going abroad to any country, he can directly buy a local SIM card and use it without changing the mobile phone. At present, due to the different communication standards supported by different countries, mobile phones cannot be inserted into SIM cards of other countries.
In the next TD-LTE development plan, Zhao Jibin said that he will do three main tasks: First, continue to promote the integrated development of LTE TDD / FDD. China Mobile will join the industry to launch more and better converged networking solutions and converged global roaming terminals. Within this year, China Mobile Hong Kong will also commercialize the first LTE TDD / FDD converged network in Asia.
Second, continuously expand the scale of TD-LTE deployment. During the year, 20,000 base stations will be completed, and the purchase of TD-LTE equipment in more than 100 cities will be launched, and the scale of trial commercial users will be further expanded. Third, continue to strongly support GTI, an international TD-LTE cooperation platform, relying on this platform to work closely with international organizations, international operators, and global industries to jointly promote the global development of TD-LTE.
According to the latest survey data of GSA (Global Association of Mobile Device Suppliers), there are currently 301 operators worldwide vigorously deploying LTE projects, of which 242 commercial LTE networks are being deployed, commercialized or planned in 81 countries and regions. In addition, 59 operators in 14 countries and regions are conducting LTE trials and tests.
