The China-South Korea match at the 40,000-person He Long Sports Center revealed the secrets behind the "Wireless Bee Madness"

On March 23, the Chinese national football team won the World Cup qualifiers between China and South Korea. As the home stadium of the Chinese national football team, the He Long Sports Center was fully upgraded and renovated before the game to help the Chinese national football team and once again became a blessed place for the Chinese national football team. With the help of Ruijie Networks, the He Long Sports Center has achieved high-quality Wi-Fi coverage for 55,000 seats. Ruijie Networks' "micro-cell" solution for venues enables fans to truly surf the Internet at high speed and interact with everyone at the He Long Sports Center.

On this basis, the wireless level of the venue's press center, office area and outdoor area has also been greatly improved. Ruijie RG-MCP cloud marketing platform also helps the venue solve the worries of commercial operations.

He Long Sports Center

The pain of wireless installation in a stadium with 10,000 people

He Long Sports Center covers an area of ​​150,000 square meters and can accommodate 55,000 spectators. It is the fourth largest sports stadium in China. Large sports stadiums are one of the most difficult scenarios for wireless installation. Tens of thousands of people need a large number of wireless APs to access. Due to the same-frequency interference problem, the more APs are deployed in the venue, the more serious the interference. However, if the number of deployments is insufficient, there will be an embarrassing situation of signal blind spots. At the same time, the signal coverage effect of traditional AP + directional antenna deployment depends on antenna debugging, and construction errors have a great impact on the coverage effect.

In order to meet the wireless system requirements of tens of thousands of spectators at a game, the venue needs to invest a lot of manpower and material resources in the installation, debugging and maintenance of network equipment. How to make these investments bring business guarantees and profits to the venue is the "operation" problem faced by the venue.

"Internet +" sports venues need to transform

Driven by the "Internet +" sports strategy, the market-oriented operation of stadiums has become a major trend: how to use big data, smart hardware and APP to improve the pertinence and effectiveness of sports marketing, and migrate the offline interactions between audiences, ticketing companies, sponsors and venues to online; and the implementation of these Internet applications and big data are inseparable from the high-load and high-stability wireless networks in the venues, as well as efficient and accurate marketing platforms.

1. "Micro Cell" solution refreshes the venue's wireless coverage experience

Microcells do not require a lot of antenna azimuth adjustments, which reduces the difficulty of engineering debugging and saves construction time. In addition, APs are deployed under the seats, and the ground seats block the signal, control the equipment coverage, optimize interference problems, and increase deployment points, thereby increasing user capacity and ensuring access for ultra-high-density users; compared with indoor ceiling-mounted APs, the signal will not be covered from top to bottom and reflected from the ground, and the signal is easier to control. In this solution, 800 microcell RG-AP520 (HD) covers the 55,000-person stand area in the stadium. The high-speed and stable wireless network meets the fans' online multi-viewing, match point playback and other network needs, greatly improving the viewing experience.

2. RG-MCP cloud marketing platform lights up the "wisdom" of venue operations

While providing high-quality Wi-Fi, Ruijie's RG-MCP cloud marketing platform also enables the He Long Sports Center to quickly attract fans through the venue's WeChat official account, build channels for online interaction, enhance the interaction and stickiness between the venue and the audience, and achieve innovative precision marketing. Help the He Long Sports Center to create a "people-oriented" sports information service. This measure not only improves the fans' viewing experience and attracts more spectators to watch the game on site, but also helps managers better implement the "Internet +" strategy of the future sports industry. As the first smart sports venue in China with 100,000-level terminal carrying and precision marketing capabilities, the He Long Sports Center will provide reference for the information construction and innovative operation of other large sports venues.

3. Multiple measures deployed to demonstrate wireless strength

For the World Cup qualifiers, the Chinese Football Association required wireless and wired deployment in the press release area, press box, and around the stadium. In addition, wireless signal coverage of the news center and office area was required to ensure real-time transmission and broadcast of high-definition video, audio, and text of the event by the media. For the indoor office area with thick walls in the stadium, Ruijie adopted the intelligent distribution + deployment solution with antennas in the room. The intelligent distribution + solution adopts Ruijie's latest "main AP + micro AP" multi-level distributed architecture, achieving lossless transmission of performance under the 100-meter network line. At the same time, it fully complies with the integrated wiring specifications and meets the structured wiring standards. Whether it is the early weak current intelligent design, mid-term construction implementation, or later management and maintenance, it has brought great convenience and brought users the best ultra-high wireless performance.

After visiting the He Long Sports Center, leaders of the Chinese Football Association and relevant departments of the Asian Football Confederation gave high recognition to the venue's hardware facilities, live TV broadcasts, wireless coverage and other preparations for the event. The person in charge of the Information Center of the He Long Sports Center said: "The improvement of the soft and hard strength of the venue's wireless network has laid a solid foundation for the upcoming competition services, and also enabled us to undertake more large-scale events and concerts, gradually transforming into a market-oriented sports venue, and better embracing future development."

It is understood that Ruijie has often been seen in the network support of large-scale sports stadium construction projects and major events since the 2008 Beijing Olympic Games. As a leading brand of data communication solutions in China, Ruijie Networks has successively built basic networks such as the Beijing Olympic Village, Beijing Olympic Forest Park, and Tianjin Olympic Center Stadium, and has undertaken important operation and maintenance support tasks in many events such as the Rio Olympics, the London Olympics, the Shenzhen Universiade, the Guangzhou Asian Games, the Liaoning National Games, the Fuzhou Youth Games, and the Ordos National Games.
