At the 2018 PyeongChang Winter Olympics, a large wave of 5G application scenes was amazing. Japan also announced the commercial 5G network at the 2020 Tokyo Olympics, laying out 5G applications.
At the "2018 Future ICT International Symposium" held on the 27th, the Chinese Academy of Engineering academician He Hezhen said that 5G can be applied to enhance mobile broadband, ultra-reliable delay, wide coverage and large connection scenarios, which will be the Beijing 2022 Winter Olympics. Bringing a lot of valuable applications, but it also faces great challenges.
Speed and passion in 5G environment
The Winter Olympics is an arena of speed and passion.
“French alpine skiers skating at speeds of up to 250 km, only 5G can track this speed.” He He said that the Beijing Winter Olympics will use 5G low latency, high bandwidth, high reliability and large connection performance to realize car networking and things. Networking, VR/AR and other applications.
The athletes will be equipped with sensors, high-definition cameras and 5G communication modules. The data will be transmitted in real time through 5G. The audience can track any player, feel the game from the perspective of the athletes, measure the speed of the exercise, and also sense the fatigue of the athletes.
In the bobsleigh race, all the fronts of the sled are equipped with mini-cameras, and the audience outside the arena can also get the feeling of being in the sled. The referee is equipped with a 360-degree camera and then connected via 5G technology. The audience can experience the whole game through the referee's perspective.
In the 4G era, VR/AR is difficult to develop, and 5G will provide a network foundation for VR/AR development.
“In order to solve the VR/AR vertigo discomfort problem, it is necessary to improve the refresh rate and reduce the delay.” He He said that in the 5G environment, the audience wears a helmet and sits on the simulated bobsleigh, which can be like an Olympic athlete on the virtual track. Enjoy the fun of simulated ice and snow.
In addition, the venue is equipped with intelligent sensors of various shapes. Through the 5G network, information such as crowd intensity, potential hazard analysis, and equipment operation status are transmitted to the command center in time to ensure the normal operation of the event.
There are several challenges for the Beijing Winter Olympics
However, he also said frankly that although the PyeongChang Winter Olympics in Korea is not true 5G, its bandwidth is not worse than the 5G standard. There will be some challenges for China's 5G to be applied to the Winter Olympics.
China's 5G commercial will start from the Sub 6GHz band. Currently, Telecom and China Unicom operators only get 100MHz at 3.5GHz. China Mobile is expected to obtain 100-150MHz at 2.6GHz. China Mobile can also get 100MHz at 4.9GHz. 200MHz bandwidth, peak rate is only 5Gbps, less than the rate of PyeongChang Winter Olympics.
"The current R&D plan can support China's 5G system with more than 6GHz in 2022, and it is still not very sure." Hehe mentioned.
In the roundtable forum of the conference, Yu Hong, director of the technical department of the Beijing Winter Olympics Organizing Committee, revealed that based on 5G technology, the Ministry of Science and Technology has taken the lead in formulating the Science and Technology Winter Olympics 2022 action plan. In addition, Beijing has also carried out related work, which will be the latest. The technology used for winter Olympics.
Jiang Guangzhi, deputy inspector of the Beijing Municipal Bureau of Economics and Information Technology, said that in conjunction with the Beijing 5G development implementation plan, a series of policy measures will be introduced to support the construction of base stations, including making full use of existing base station resources and actively promoting multi-pole multiplexing.
As the official communication service partner of the Beijing Winter Olympics, Du Yonghong, deputy director of the China Unicom Winter Olympics Office, said that the extremely cold and windy weather of minus 20 degrees Celsius will bring great challenges to equipment operation. She also said that after the integration of 5G technology with edge computing, cloud computing and artificial intelligence, it can build or optimize many common technologies and spawn a platform for many smart applications. “After these technologies have been verified at the Olympics, they can also promote industrial upgrading in all walks of life faster.”
