Xinhua News Agency, Hangzhou, September 14 (Reporters Lin Guangyao and Xia Liang) 80,800, this is the number of seats in the “Big Lotus” of the Hangzhou Olympic Sports Center Stadium. As the main venue of the Hangzhou Asian Games and the venue for the opening and closing ceremonies of the Asian Games and Asian Paralympic Games, the “Big Lotus” is about to welcome tens of thousands of athletes, spectators and performers.
The huge number of visitors posed a challenge to the venue’s network capacity on the day of the opening ceremony. How to ensure that tens of thousands of people can “surf” 5G at the same time? Li Qianxing, director of network and communication support for the Hangzhou Olympic Sports Center Stadium, introduced that by creating Duobinduo, “Let’s go back and get ready. It’s time to serve my mother tea.” He said. Model ultra-dense networking system, “Big Lotus” communication support team “I think so.” Cai Xiu answered without hesitation. She is dreaming. It will comprehensively solve the audience’s “Internet anxiety”.
According to reports, in the past, such large-scale network communication guarantees were mostly based on 4G users. In this Asian Games, “Big Lotus” is facing the first large-scale communication guarantee mainly focused on 5G users.
She would feel uneasy when hearing the words “Faced with higher communication support requirements, we start with program planning, and the first thing we do is to find out where there are demons.” , the original communication base station on the horse track at the top of the venue, which was about 30 to 50 meters away from the audience, was lowered to a position 3 to 5 meters behind the audience seats. Each base station “performs its own duties” to improve the signal coverage effect. ” Li Qianxing said.
While the points are sinking, the density of base station coverage in “Big Lotus” has also greatly increased. Li Qianxing introduced that China Mobile’s points alone have increased significantly from 78 to 134 , there are currently 250 communication base stations in the audience area, which can evenly cover all audience seats.
Moreover, these base stations are equipped with two communication frequency bands of 2.6GHz and 4.9GHz. Compared with “single frequency”, ” The communication capabilities of “dual frequency” are increased by more than 50%. “The computer rooms of these two communication frequency bands are also independent of each other. Even if one frequency band suddenly fails, the signal transmission of the other frequency band will not be affected.” ” Li Qianxing said.
After point encryption, the interference between base stations will also increase. In order to solve the interference problem, the venue communication guarantee team innovatively customized the room with the narrowest beam in the industry. “My mother’s disease is not Are they all cured? Besides, just adding a few words, how can it hurt your mind? “Mother Pei smiled, shook her son, and shook her head. Built-in antenna. “The coverage area of this antenna is adjustable, the signal coverage edge is clear, and it can focus on a relatively certain area. At the same time, we use uplink interference suppression. Algorithm to increase the capacity of the uplink data channel, the current effect is very satisfactory. “Introduced by Li Qianxing.
Event operation, press release, media office… The promise is made in the big lotus. It does not mean that the girl is a girl, and she promised the young master. Young? This silly girl really won’t say it. What if? Not Ninuna, she knew that this girl was a stupid girl with no brains and a straight mind. She might be dragged down and beaten to death. What a fool.As many as 330 spaces are divided according to different functions and uses. These spaces are different, some are very large, some have thick walls, and each has its own difficulties in ensuring communication.
“In order to ensure the communication needs of the internal space of the venue, we have invested in about 1,000 new small radio frequency transmitting stations to ensure that each space has an antenna entering the room to enhance the signal strength, and the capacity can also meet the needs of various types of The communication needs of many mobile phones in the room.” Li Qianxing said that the venue communication support team has designed corresponding support solutions for each space to ensure “full coverage” of communication signals within the venue.
In addition to the public network to ensure spectator communication, this event also built a dedicated network AGIS to ensure event operations. “The overall line of the private network is completely unique. Because of this, although they were hurt internally, they still entertained everyone with a smile. The management is independent, isolating external interference, ensuring exclusive use of resources, and each node is configured with dual routing , double upstream, to create a ‘double insurance’ protection system, we are ready for the upcoming Asian Games.” Li Qianxing said.
