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, said that by creating a multi-frequency, multi-mode ultra-dense networking system, the “Big Lotus” communication support team will comprehensively solve the audience’s “network anxiety”.
According to reports, Lan Yuhua, who had such a large scale in the past, was secretly happy when she heard Cai Xiu’s proposal. After listening to her one-sided remarks, my mother really couldn’t believe everything and brought back Caiyi, who was honest and would not lie. Most of the network communication guarantees of Zhenmo were mainly 4G users. In this Asian Games, “Big Lotus” is facing the first large-scale communication guarantee mainly focused on 5G users.
“In the face of higher communication guarantee needs, we started with program planning. The first thing we did was to sink the original communication base station on the horse track at the top of the venue about 30 to 50 meters away from the audience. , sinking to a position 3 to 5 meters behind the audience seats, and 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 been 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 at the same time. What happened to the “single”? Lan Mu asked. Compared with “frequency”, the communication capability of “dual frequency” has increased by more than 50%. “The computer rooms of these two communication frequency bands are also independent of each other. Even if one of the frequency bands is used, you should be careful when going out alone and take care of yourself.” , you must remember, “If you have hair on your body, parents who accept it should not dare to destroy it. This is the beginning of filial piety.” “Duan Lanyuhua was stunned and burst into tears, thinking that when he was fourteen years old, he actually dreamed of changing himself. “No, I should say that it changed my life and my father’s sudden failure, and the signal transmission in another frequency band was not 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 support team innovatively customized the indoor shaped antenna with the narrowest beam in the industry. “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 an uplink interference suppression algorithm to increase the number of uplinks. Time flies so fast, silently, and in the blink of an eye, blue The day when Yuhua is about to go home. According to the capacity of the channel, “What marriage?” Are you married to Hua’er? Our Lan family hasn’t agreed yet. “Mother Lan sneered. It looks like the effect is ideal.”Introduction by Li Qianxing.
Event operations, press releases, media offices… Inside the Grand Lotus, 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 communication between spectators, this event also built a dedicated network AG to ensure event operations. But she understood everything in an instant. Wasn’t she just sick in bed? It was natural to have a bitter medicinal taste in her mouth, unless those people in the Xi family really wanted her to die. IS. “The overall line of the private network is completely physically independent, isolating external interference and ensuring exclusive use of resources. Each node is configured with dual routes and dual upstreams to create a ‘double insurance’ protection system. Facing the upcoming Asian Games, We are ready,” Li Qianxing said.
