On February 20th, 2022, the unprecedented Beijing Winter Olympics came to a successful conclusion. This grand event of the century featured amazing grand ceremony, shining Olympic athletes, and immortal sportsmanship. "Behind the scenes" of the wonderful games hides another more intense and orderly "battlefield" for competition support. Tens of thousands of support troops shoulder heavy responsibilities, display lofty sentiments, and pour into solid "fronts" to hold up piles as heavy as a thousand pounds of force.

In this mighty army, a team of "Double Olympics" state-owned enterprise is active. In the vast world of ice and snow, it quietly and vigorously promoted the games behind the scenes, and played a key role as the "air messenger" of the games. "One net" which traverses mountains and seas, crosses the geographical limits of two major cities and three major competition areas, connects in series the real-time communication between the event commanders and organizers safely, accurately, stably and fast. CAPINFO, a team of state-owned enterprise that had showed strong support on the occasion of the 2008 Beijing Summer Olympic Games, went to the "Double Olympics date " 14 years later again. It went all out to prevent risks, ensure peace and stability, and firmly defended the security and stability of government affairs communication and informatization in the Winter Olympics, achieving the goal of "0" accident, and presented brilliant answers to the world-renowned "Double Olympics event" with hard core strength and perfect technical performance.

Three years' efforts to get ready for fight

The years of 2019, 2020 and 2021, these thousand days recorded a long and gradual process of vigorous development. Winter Olympics infrastructure construction was in full swing. Delineating the scope, finely dividing the area, locking points, expanding the area, putting into construction and re-guarding the patrol, the engineers of CAPINFO shuttled between the mountains and plains in downtown Beijing and Yanqing District, to carefully draw the "new picture" of the infrastructure of Winter Olympics. Towers of base stations have risen from the ground, and these tall "giants" will support a fast and efficient "giant network" and take on the arduous mission of "spreading messages for thousands of miles" during the Games.

Unfolding this huge "road map for infrastructure", in the past three years, engineers have worked hard together to build a large-capacity, high-speed, reliable, safe and controllable 1.4G broadband trunked private network by adopting the B-TrunC technical standard of China's independent IP rights, and successfully completed network construction projects such as Winter Olympics venues, service facilities, important roads and key areas in Beijing and Yanqing divisions of the Winter Olympics, and built more than 500 macro base stations equipped with emergency communication vehicles and other support facilities, which covers the inner city within the Fifth Ring Road and the whole area of Chaoyang District, city sub-center administrative office area, the central city of the outer suburb, and the key areas of the World Horticultural Exposition and the Winter Olympics, including nearly 200 base stations for the Winter Olympics venues, dedicated roads, service facilities and key support areas. Through the implementation of the "new infrastructure" to strengthen infrastructure and expand area, not only the coverage of competition venues and non-competition venues in the Winter Olympics is realized to ensure the first-class communication quality of international competitions, but also the network communication range is expanded in an all-round way, forming the "radiation effect".

Unforgettable is not only these grand plan and spectacular landscape, but also the ordinary days of silent protection and persistence. If "drawing" and "building" are thick and heavy colors, "patrolling" and "protecting" are indispensable meticulous details. For 1000 days and nights, engineers walked among the base stations built in the mountains. For smooth progress, they have overcome all kinds of obstacles and difficulties. In the special areas of the Winter Olympic Games, they have to put on heavy epidemic protective clothing to complete elaborate laying and patrol inspection. In the snow and ice of -30° in Yanqing Division, they braved the extreme cold, went back and forth for tens of kilometers, and even climbed over the snow-covered mountains like "Polar Expedition", thereby carefully checking the operation of each station. Breath turned into ice immediately in these mountains. It's very cold, but no one flinches, and it's bitter, but there will be no sloppiness.

In the past three years, the smooth operation and complete guarantee of the new infrastructure of Winter Olympics recorded the hardships and persistence of this group of loyal "station builders" and "station keepers".

Escorting the Olympic combat event 

Tempered into a steel. On February 4th, 2022, the Beijing Winter Olympics officially kicked off in the atmosphere of happy new year. Previously, the CAPINFO Team, which had successfully drilled in three rounds of the Winter Olympics test competition, had already been stationed in advance and got ready. During the countdown to the Winter Olympics and the 16-day competition period, this storm team composed of 200 engineers served the communication and command of the competition with steady style and exquisite skills, ensuring the success of the competition. With a glorious responsibility and mission, they witnessed every historical moment in this event.

On January 27th, national leaders came to the Winter Olympic Organizing Committee to inspect the preparations for the Games. Engineers steadily operated the 1.4G broadband trunked private network to video transmit the arrival and departure of the airport for the leaders, and support the on-site connection with the person in charge of Yanqing Division for listening to report. The network operation and return connection were clear and stable. From Feb. 3 to Feb. 4, during the torch relay of the Winter Olympics, engineers collected real-time high-definition images of each scene of the torch relay through the private network and sent them back to the torch relay headquarters with high quality to ensure the orderly organization of the torch relay. On Feb. 4, the Winter Olympics was grandly opened. Engineers gave full technical support to key business departments, played an important supporting role in the command and dispatch of the whole ceremony, and provided unimpeded communication "track" for the successful opening ceremony. During the Games, during the multi-scene command liaison between the Main Operation Center of the Winter Olympics and the Winter Olympic venues, engineers continued to exert their technical support and guarantee function. On Feb. 20, with the grand scene of the Winter Olympics dropping the curtain, this strong communication support "team" realized the complete guarantee of zero-risk failure in the whole process.

The perfect curtain call of the Winter Olympics is also the perfect ending for the fight of every team behind the scenes. The fight team of the CAPINFO is well-deserved and presented a wonderful picture scroll for the grand event of the century.

The 1.4G broadband trunked private network operated by the main services of Capital Information plays an important role in the "new infrastructure" of the Winter Olympics. The coverage of the games and services is wide and comprehensive, the operation is safe and stable, the transmission is stable and efficient, the technical force is advanced and outstanding, and the "smart terminal" can be connected to the three regions in series with high efficiency, breaking through the tradition and realizing multiple "video-audio" joint transmission. The full application of the private network in the Games has set up an efficient "communication fast lane" between the Main Operations Center (MOC) of the Winter Olympics and the competition venues, and has become the "thousands of miles messenger" in the three districts of Beijing-Yanqing Division-Zhangjiakou Division, which has also added a stronger flavor of "wisdom and technology" to the Games.

He has been stationed in the "Information Support Team" of the Winter Olympic Organizing Committee for many years, providing the most stable, efficient and high-quality communication and technical support services for the daily work of the Winter Olympic Organizing Committee and during the Games, and becoming a loyal "network butler in Austria".

A clear era, a clear mission, is an oath, and it is also a picture scroll of numerous scenes that we have created.

The stormtroopers are conscientious.

The creation of a grand event comes from every screw.

In the grand scheme of the Winter Olympics, every CAPINFO team and every CAPINFO person who carries the cultural banner of "stressing politics, being responsible and trustworthy" has revealed the distinctive qualities of the iron-army team.

1.4G broadband cluster private network team is the "loyal guardian" to protect the smooth and safe private network. Since 2019, the team has worked hard to extensively expand the "New Infrastructure for Winter Olympics", completed the construction of private network base stations in key areas of the Winter Olympics with high standards, broke through the "geographical restrictions" to form multi-network "interconnection and intercommunication", and optimized the multimedia application of "smart terminals", so that the 1.4G broadband cluster private network, which debuted at the Winter Olympics for the first time, has formed the outstanding characteristic advantage of serving large-scale international competitions.

149 engineers of the team strongly defended the games. All staff are on duty 7×24 hours a day, building a "fast track" with 1.4G broadband trunked private network communication and command in several key occasions such as the main operation center, technical operation center, competition venues, airports and torch relay points of the Winter Olympics during the whole process, whole scene and all links of the torch relay, opening ceremony, stadium scheduling and closing ceremony.

The scene of struggle is particularly hard and unforgettable. There are still a few months before the opening of the Games. Due to the epidemic situation, many engineers in the team have already entered the completely closed state of the competition venue. They stick to it day and night, can't be reunited with their families for a long time, and have to stay in the whole Spring Festival period. Sometimes, when they think of their parents at home, hard-working child’s mothers and fathers, their hearts are always sour. During the torch relay ceremony of the Winter Olympics, team members spent a special " Spring Festival's Eve". When all the families celebrate the reunion, engineers grope for blind spots along the Badaling Great Wall in the snow and cold night. "Blind-filling" is of great significance and will set up a smooth communication channel for the torch relay. Cold and homesick, but when thinking of this responsibility, everyone's heart is still warm ...

“Xiao  Ma ” is a tower-keeper in the team who "can climb the high tower and the snowy mountain", and this reputation comes from years of hard work. Over the years, he has been responsible for the inspection of base stations. At the beginning of 2022, since he began to be responsible for the support of Yanqing Winter Olympics Alpine Ski Center, Ma Pengzhi rushed to the starting area of alpine skiing at an altitude of 2,200 meters every day for signal testing and base station inspection. It is extremely hard to work in the snow and ice. Every time he went to the starting area, his whole body was frozen stiff. This was just the beginning. In the cold weather of - 30℃, he had to wear heavy protective clothing to work for one hour, and carried out detailed inspection and testing on the equipment and facilities that are hard to freeze. This was just an ordinary day. The snow was often unpredictable, sometimes the wind was too strong, and when the cable car that usually transported him to the departure area stops, he would quickly become a "Snow Man", wearing ice claws and helmets, and climbing hard on the snowy road against the cold wind. Many base stations had no ready-made roads, therefore he had to climb along steep slopes and cliffs. Along the way, he climbed over the rockfall net, met barbed plants, and fell into steep pits ... Little Horse encountered many difficulties and even dangers. He had fears, but the only thing he didn't think about was flinching. "Due to this responsibility, no matter what, we can't delay the big deal." With tenacious will and superb technical ability, Little Horse realized the oath mission of a loyal guardian.

This is a story that lasts for seven years. In 2014, when the Beijing Winter Olympics Bid Committee was established, this team was dispatched to the forefront, and successively undertook the informatization support work of the Beijing Winter Olympics Bid Committee and the office area of the headquarters of the Winter Olympic Organizing Committee, which provided important backup support for the preparation of the Winter Olympics.

The past seven years witnessed the evolution of Beijing Winter Olympics, as well as the ordinary bits and pieces of daily work of this team. Their work is like a screw, ordinary and indispensable. In the seven years since they stationed for guarantee, the team has always been diligent and dedicated. This small vanguard, composed of 30 engineers, has taken on the responsibility of "network butler", and shouldered the security work for the office area, event terminal and network operation support, becoming an important supporting force on the support line of the Winter Olympics.

Sharpen a sword every seven years. In 2022, during the guarantee stage of the Winter Olympics games, all the team members reached the front line. They put aside all their work and life, stuck to their duty 7×24 hours a day "behind the scenes", making every effort for the full operation of the office facilities of the Winter Olympic Organizing Committee and the competition venues. They wrote their own wonderful stories of the Winter Olympics with seven years of diligence and steadfastness. "The heroes behind the scenes are equally wonderful!". 

At this moment, applause and praise are dedicated to everyone who has made great efforts to create the grand event.
