According to the Ministry of Industry and Information Technology, according to the relevant enterprise application, according to the telecommunications regulations and the telecommunications business license management measures, through the comprehensive review of the application of the company's financial capabilities, technical capabilities and operating capabilities, issued to China Telecom and China Unicom "LTE / fourth generation The Digital Cellular Mobile Telecommunications Service (LTE FDD) "operating license" supports enterprises in integrating their actual conditions to promote the integrated development of 4G and promote information consumption.
On December 4, 2013, the Ministry of Industry and Information Technology issued the first TD-LTE standard 4G license to China Mobile, China Telecom and China Unicom. At present, China's 4G standard includes TD-LTE and FDD-LTE. FDD-LTE is the mainstream standard of most countries in Europe and the United States, and TD-LTE is the dominant standard in China.
From the perspective of speed, theoretically FDD-LTE is higher than TD-LTE, but from the deployment point of view, TD-LTE has the advantage of better use of spectrum resources, suitable for deployment in dense areas, so the two systems have their own advantages and disadvantages. No matter what.
China Mobile is the main promoter of TD-LTE. Last year was a step ahead. The latest data as of the end of 2014 shows that China Mobile’s 4G subscribers have exceeded 90 million, with 4G base stations exceeding 700,000, covering the county level, and the world’s largest 4G network.
In contrast, China Telecom and China Unicom have obtained TD-LTE licenses, but in terms of technological evolution, FDD-LTE is more in line with its future development. According to Tencent Technology, in the past year, the two operators have never stopped applying to the Ministry of Industry and Information Technology for issuing FDD-LTE licenses.
On June 27, 2014, the Ministry of Industry and Information Technology approved China Telecom and China Unicom to carry out FDD-LTE and TD-LTE hybrid networking trials in 16 cities respectively. On August 28, the hybrid network test scope was expanded to 40 cities, December 18 The day was increased to 56 cities.
While supporting the country-led TD-LTE, China Telecom and China Unicom are also actively deploying hybrid networking. The FDD/TDD convergence network will become the consensus in the industry. At present, there are more than 300 operators supporting FDD-LTE worldwide and only 30 supporting TD-LTE.
For users, a standard 4G network is more of a kind of 4G service. The competition brought about by various 4G services will make the tariffs more popular, thus promoting the rapid adoption of 4G.
According to the overall plan of the three major operators, China’s 4G subscribers are expected to reach 450 million in 2015, accounting for one-third of all mobile subscribers in the country.
