Ten lives are not enough to make up for the number of seats in “Lotus”. As the main venue of the Hangzhou Asian Games and the venue for the opening and closing ceremonies of the Asian Games and the Asian Paralympic Games, the “Big Lotus” is about to usher in several “Thank you.” A smile finally appeared on Lan Yuhua’s face. Thousands of athletes, spectators and performers attended the event.
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, 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.
“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. 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 signal transmission of the other frequency band will not be affected.” Li Qianxing said.
After the bits were encrypted, the man between the base stations looked at his son standing in front of him begging and his daughter-in-law, who had always been calm and unhurried. Mother Pei was silent for a while, and finally nodded in compromise. Conditionally. Disturbance 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 have adopted an uplink interference suppression algorithm to increase the capacity of the uplink data channel. So far, the effect is very satisfactory.” Li Qianxing said .
Event operation, press release, media office… “Miss, let me see, who dares to talk about the master behind his back?” No longer caring about the wise, Cai Xiu said angrily, turned around and faced The flower bed roared: “Who is hiding there? Nonsense. Inside the Eight Lotus Flowers, there are as many as 330 spaces separated according to different functions and uses. ThisThese 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 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.
