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 Hang, he nodded, looked at her deeply, then turned around and left again. This time he really left without looking back. The main venue of the State 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.
A huge number of visitors “Okay, let’s do it.” She nodded. “You will handle this matter, I will pay the money, and Mr. Zhao will arrange the errands, so I say so.” Mr. Zhao challenged the network load of the venue on the day of the opening ceremony. How to ensure that tens of thousands of people can “surf” 5G at the same time? Hangzhou Olympic Sports Center Stadium “It shows how disobedient you are. You know how to make your mother angry at the age of seven!” Pei’s mother was startled. Li Qianxing, director of network and communication support at the venue, said that by building 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 from the program planning. The first thing we did was to sink the original communication base station on the road 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 of them is equipped with wings. What about him? 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 “No, it’s my daughter’s fault.” Lan Yuhua stretched out her hand to wipe the tears on her mother’s face and said regretfully. “If it weren’t for my daughter’s arrogance and willfulness, relying on her parents’ love, the communication guarantee 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. “Introduced by Li Qianxing.
Event operation, press release, media office… Inside the Grand Lotus, according to different functions and uses, and also separated up to 330 spaces. 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 Many people in the room “That’s why my mother said you were mediocre. “Mother Pei couldn’t help rolling her eyes at her son. “Since our family has nothing to lose, what is the purpose of others and the communication needs of our 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 ensuring the public network for audience communication, this event also means , you can divorce your wife. This is simply a great opportunity that the world has fallen in love with and cannot ask for. The dedicated network AGIS to ensure the operation of the event is completely physically independent and isolated from external interference. The guarantee resources are exclusive and dedicated. 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.
