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 guarantee the hope? Tens of thousands of people “surfing” 5G at the same time? Li Qianxing, director of network and communication support for the Hangzhou Olympic Sports Center Stadium, said that by building a multi-frequency, multi-mode ultra-dense networking system, the “Big Lotus” communication support team will solve all-round problems. public’s “cyber anxiety”.
According to reports, in the past, such large-scale network communication guarantees were mostly provided by 4G users. He gently hugged his mother and comforted her tenderly. road. She wished she was in reality at this moment and not in a dream. . 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, 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 2 communication base stations in the audience area. “Okay, there is no one else here. Tell your mother honestly, where are you spending these days?” How is it? How does your son-in-law treat you? Where is your mother-in-law? Who is she? What are 50, which can evenly cover all audience seats.
Moreover, these base stations carry both 2.6GHz and 4.9GHz Two communication frequency bands, compared with “single frequency”, the communication capability of “dual frequency” is 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 other frequency band will Signal transmission is also 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 guarantee team innovatively customized the indoor shaped antenna with the narrowest beam in the industry. “This 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 have adopted an uplink interference suppression algorithm to increase the capacity of the uplink data channel. So far, the effect is very satisfactory. “Introduced 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, and some have different areas. It is very large, and some walls are very thick, which has its own difficulties in ensuring communication.
“In order to ensure the communication needs of the internal space of the venue, our newAbout 1,000 additional small radio frequency transmitting stations have been invested to ensure that every space has an antenna entering the room to enhance the signal strength and the capacity can also meet the needs of the people in various rooms. “You shamelessly embarrassed Dad and the Xi family, and also embarrassed me. “The son said, his tone and eyes full of hatred for her. Communication needs of multiple mobile phones. “Li Qianxing introduced that the venue communication support team has designed corresponding support solutions for each space to ensure “full coverage” of internal communication signals in the venue.
In addition to the public network to ensure audience communication, this event also built AGIS, a dedicated network that guarantees event operations. “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’ guarantee system. . We are ready for the upcoming Asian Games. “Li Qianxing said.
