Behind Gu Ailing's victory in the Winter Olympics:

 Behind the TV broadcast where people watched the wonderful competition, the communication people silently stood by and guarded. 7×24 hours uninterrupted guarding The communication security during the Winter Olympics is a big task, especially the radio security, information communication and network security during the opening of the Winter Olympics is a top priority. The Ministry of Industry and Information Technology (MIIT) has made clear deployment and planning early on. Before the opening ceremony, the radio management department of MIIT coordinated the assignment of more than 800 frequency resources for the performance team, TV broadcast and command dispatch. The Beijing Winter Olympic Games Radio Security Command Center systematically combed through the experience of the previous five opening ceremony rehearsals in radio security work, further compacted responsibilities, refined measures, and paid close attention to implementation, and zeroed in on each of the problems found during the opening ceremony rehearsals. Since 20:00 on February 3, the radio security personnel arrived at their work sites one after another and stayed at their posts for more than 24 hours until the opening ceremony. According to the statistics, the radio management department invested more than 200 radio security personnel, activated 21 fixed monitoring stations in Beijing, deployed 6 mobile monitoring points in the National Stadium, and deployed 9 mobile monitoring vehicles in the surrounding area to conduct protective monitoring of key frequencies for the opening ceremony; 108 radio equipment security personnel were stationed at the security checkpoint of the National Stadium and various venues at the far end to check the radio equipment entering the core area. A total of 19 sets of wireless microphones, walkie-talkies and other equipment without special stickers were intercepted. During the protection period, the Ministry of Network Security Emergency Command Center organized the Beijing and Hebei Communication Administration, China Unicom, China Telecom, China Mobile, China Weitong, China Academy of Information and Communication Technology, China Internet Network Information Center, Ari, Tencent and other units on centralized video duty, and all units in the industry were on the front line of protection, on duty and in position to carry out 7×24-hour duty and emergency disposal and other protection work. CommuniLink: Helping every wonderful moment As the only official communication partner of Beijing 2022 Winter Olympic Games and Winter Paralympic Games, China Unicom has set up a communication technology operation support team of nearly 5,000 people. In the closed circle of each competition venue, there are busy figures of Unicom people. The highest point of the Shougang Grand Jumping Platform is 60 meters, and the competition track is 164 meters long and 34 meters wide. The entire jumping platform is exposed to the open air, and the overhead cables are intertwined and complicated, which makes the overhead operation doubly difficult. The communication service team of China Unicom, which is rooted in this area, has also practiced some "aerial stunts". Every day, with the first light in the morning, the CommuniLink team has to start their daily inspection, checking the equipment on each floor and the cables outside the building, whether the power supply is solid, whether the switch and AP are running normally, and so on. During the busy work, they have taken this picture: the integrated wiring master, with his feet apart on the steel frame, has to lay the network cable with one hand and find the balance with the other hand. The 5G network not only realized the gigabit Internet access, but also the signal stability no matter which scenes were switched to, helping every wonderful moment of the Winter Olympic Games. Telecommunication: 11 provinces joined hands to provide network security for the Winter Olympics China Telecom has formulated a detailed communication protection work plan for the Winter Olympic Games, specifying 22 specific tasks and measures in 6 categories, focusing on important areas such as Beijing and Hebei competition venues, important tasks such as digital trunking communication, important activities such as serving the opening ceremony, and important services such as public communication and IPTV viewing, and constructing a protection system covering the core area, Beijing and Hebei, and linking the whole network in the two places and three competition areas. Combined with the overlapping time between the Ice and Snow Festival and the Spring Festival holidays, as well as the cross-province, multi-location and multi-stadium international events, China Telecom coordinated the major events and holiday protection, local and network-wide protection, domestic and international protection, key service protection and network-wide operation safety, protection and epidemic prevention, etc., and firmly grasped the effective implementation of the tasks and measures. In order to ensure a good network environment in the national stadium for the opening ceremony of the Ice and Snow Festival, China Telecom launched the optimization of base stations in the Bird's Nest venue in advance to ensure that there are no dead corners and full coverage of 5G/4G signals inside and outside the venue; in addition, it also set up an intelligent analysis system for IPTV Tianyi HD video service to monitor live channels in real time to ensure smooth, clear and stable transmission of live programs. According to statistics, as of the opening ceremony, China Telecom organized and completed nearly 1,000 emergency rehearsals for equipment failures related to the basic network, submarine cable, core network, Skywing Cloud, etc., and conducted a comprehensive investigation of hidden dangers, with more than 1.92 million units of equipment inspected, the network combed through 1,975 key risk protection plans, and unified the deployment of 14 emergency communication vehicles from 11 provinces to Beijing and Hebei for protection. Mobile: 3 years, 8 companies, 237 venues, more than 300 people As one of the providers of infrastructure network facilities and communication services for the Beijing Winter Olympic Games venues, Beijing Mobile has started the preparation of related protection work since 2018. 3 years later, Beijing Mobile has invested more than 300 people to open 237 base stations, 3 training halls, 22 non-competition venues and fully complete the construction tasks, and one 5G network covering core competition areas such as venues, highways, airports, railroads and major transportation hubs. The construction of a 5G winter Olympic guarantee network covering core competition areas and major transportation hubs such as venues, highways, airports and railways was completed. At the same time, around the Olympic venues and the Olympic Village, Beijing Mobile has designated eight Winter Olympics security halls to provide timely Winter Olympics services for the event personnel. In addition to its own services, Beijing Mobile also made use of 5G technology to empower various industries to run the Winter Olympic Games well: it built a visualized service protection platform for the Chaoyang District Winter Olympic Region, helping the Chaoyang District Government to complete the work of dispatching and commanding, emergency security and epidemic prevention and control for the Winter Olympic Games; it cooperated with Beijing Emergency Center to carry a 5G emergency vehicle with 5G+ pre-hospital emergency rescue system to serve the special needs of the public during the Olympic Games. Titan: Digital tower adds brick and mortar to the smart Winter Olympics In addition to the three major operators, China Tower has been quietly undertaking the construction and operation and maintenance of communication towers, putting into practice the concept of "green, shared, open and clean" in hosting the Olympic Games, coordinating the construction needs of the three major operators, Shouxin, Zhengtong and other units, deepening the sharing, pooling and efficient construction of information infrastructure, and realizing "synchronous planning, synchronous design, synchronous implementation and synchronous acceptance" with the main project.
