Large-capacity video transmission guarantees Asian Games

China Mobile provides consulting services in 9 languages ​​for the Asian Games

On November 12, the much-anticipated opening ceremony of the 16th Guangzhou Asian Games finally unveiled the mystery. This Asian Games is the largest number of participants in history, and because the opening ceremony is located in an open area, the local crowd is highly dense, making the communication guarantee task extremely difficult. According to statistics, during the opening ceremony of the Asian Games, in the core area of ​​the opening ceremony, the number of registered users at the peak was 41,800, and the average traffic volume was as high as 4,529 ERL / km2 per hour, an increase of 1230% over the usual time, which is equivalent to 270,000 mobile users hit 1 Minute call; instantaneous peak value reached 16800ERL / km2, traffic density exceeded the Beijing Olympics, hitting a record high; within the area of ​​40 square kilometers in the peripheral area, the number of registered users at peak times was as high as 1.52 million, and the traffic volume in hotspot areas increased by 289% compared with usual times .

In order to overcome the unprecedented challenges brought about by this year's Asian Games network security, China Mobile's innovative application series of cutting-edge technologies, such as the industry's advanced AMR (Adaptive Multi-Rate) technology and half-rate automatic Control technology improves network soft capacity without affecting user perception. At the same time, build a regional passenger flow guidance system to accurately predict and track real-time user volume and traffic volume in hotspot areas, and timely and effectively adjust the network load in a reasonable manner. The data shows that during the opening ceremony of the torch relay and the Asian Games, the success rate of on-site dialing test reached 100%, the network is running smoothly, and the quality is good.

The TD-LTE technology, which has fast transmission speed and can realize huge capacity video transmission, is undoubtedly one of the biggest highlights of this "Digital Asian Games". TD-LTE technology is the follow-up evolution technology of TD-SCDMA with independent intellectual property rights. The maximum downlink rate can reach 130Mbps, which is more than 20 times faster than the world's fastest commercial network. The user data delay can be less than 10ms. At the same time, it can provide a variety of services such as Internet access for 350Km / h high-speed mobile users, which is 2 to 3 times higher than the existing mobile communication network technology.

During the Asian Games, China Mobile built TD-LTE demonstration networks in Asian Games venues such as Tianhe Sports Center, Olympic Sports Center, Asian Games City, Haixinsha and other important Asian-related areas to showcase the latest achievements of China ’s independent innovation technology to the world. Dozens of TD-LTE business services such as instant photography, wireless telepresence conferences, high-definition wireless video surveillance, etc. were displayed by global customers, highlighting the technical advantages of TD-LTE's "wireless", "broadband" and "mobile" technologies.
