Network foundation, application bloom - Beijing's communications industry uses technology to light up the Winter Olympics

When the Olympic flame continued to spread and rise in the "Bird's Nest", Beijing once again became the focus of everyone's attention.

As an important historical node and a major landmark event in the mainland, the Beijing 2022 Winter Olympic and Paralympic Winter Games are not only the top events in the global sports world, but also an important opportunity for the mainland to show its own image, promote all-round development and invigorate the national spirit. Doing a good job in ensuring communications for the Winter Olympics is not only an unshirkable task of the communication industry, but also a rare opportunity to show the latest achievements of the mainland ICT industry.

It is an honor and a responsibility. As the regulatory authority of Beijing's communications industry, the Beijing Municipal Communications Administration led industry enterprises to carefully plan, carefully deploy, and cooperate to lay a solid foundation for holding a simple, safe and wonderful Olympic event. At the same time, new technologies and new services represented by 5G, edge computing, big data, personalized video, etc. are blooming, giving the Olympic event the color of technology, wisdom and green.

"One museum, one policy" to deal with complex situations

Time flies, for the Beijing communications industry, the communication support scenario of the 2008 Olympic Games is still vividly remembered, and the "re-examination" of the 2022 Winter Olympic and Paralympic Winter Games has followed. Although previous experience can be learned, new situations and challenges are emerging one after another. After successfully withstanding the "big test" of the Beijing 2008 Olympic Games, the Beijing communications industry has devoted itself to the new Olympic communication support work with more enthusiasm and more sufficient momentum.

Regarding the characteristics of communication support for the Beijing Winter Olympic and Paralympic Winter Games, the Ministry of Industry and Information Technology pointed out at the work conference that the communication support involved three competition areas in Beijing and Hebei, and had the characteristics of many support points, wide coverage and long duration, etc., and overall the task was arduous and difficult.

For example, the alpine ski track and bobsleigh project venues in this event are the most challenging tracks and most complex venues in the history of the Winter Olympics, respectively, because they are located in the primeval forest of Haituo Mountain in Yanqing District, with winter gusts of up to 12 levels, temperatures of minus 40 degrees, and no available communication resources within 10 kilometers of the competition area, and the extremely special natural environment has brought great challenges to the site selection and construction of base stations.

For another example, the Capital Stadium is the venue for figure skating and short track speed skating in this event, which requires multi-perspective, high-definition and low-latency live broadcast services, which put forward high requirements for the up-and-down speed of the network. The Capital Gymnasium is an old building with a history of more than 50 years, and the existing network conditions are relatively limited.

Hardware facilities are already facing huge challenges, the new crown pneumonia epidemic is capricious, how to ensure the user experience while accurately preventing and controlling the epidemic has become a major issue facing the communications industry.

In the face of unprecedented challenges, the Beijing Municipal Communications Administration organized all units to carefully plan and deploy to fully cope with the challenges of the new crown pneumonia epidemic, rain, snow and ice weather, etc., laying a solid foundation for communication support during the game.

According to the relevant personage of the Beijing Municipal Communications Administration, the management bureau has set up an industry guarantee leading group and a dual guarantee system inside and outside the red line, and steadily promoted various work in accordance with the five stages of preparation and promotion, testing and inspection, rectification and improvement, race time guarantee and summary and closing, and the group prepared a "one museum, one policy" plan, which clarified the specific contents of communication support, epidemic prevention and control, emergency disposal, etc., to ensure the smooth progress of the test match and the main game.

With the strongest network, protect the glory of the Olympic Games

Network infrastructure is the premise and foundation for providing Communication Support for the Olympic Games, in order to weave a dense communication network and build a solid foundation for support, the Beijing Municipal Communications Administration organized Beijing Unicom, Beijing Mobile, Beijing Telecom and Beijing Tower to undertake the construction of communication infrastructure such as communication optical cables, communication towers, indoor distribution systems and other communication infrastructure within the scope of "renovating venues, new venues, temporary venues and transportation facilities"; to overcome the complex geomorphology, narrow space, weak communication network coverage foundation and the impact of the new crown pneumonia epidemic and other unfavorable factors. Continue to strengthen the construction and guarantee of the communication network in beijing, and promote the construction of communication infrastructure in various competition areas, competition and non-competition venues, and major transportation trunk lines. With the efforts of all parties, the communication infrastructure has covered all competition areas of the Winter Olympic Games and the Beijing-Lili Expressway and the Beijing-Zhangjiang High-speed Railway, providing an important resource platform for the guarantee of various events.

With the advantages of high speed, low latency and large bandwidth, 5G communication network has become the protagonist in the Winter Olympic Games. Under the leadership of the Beijing Municipal Communications Administration, major operators have stepped up the construction of 5G networks to provide assistance for the Smart Winter Olympics.

Su Shaolin, director of the Beijing Municipal Communications Administration, said that in order to ensure high-quality network operation security and smooth communication services, Beijing has opened a total of 52,000 5G base stations in 2021, with an average of 23.7 5G base stations per 10,000 people, ranking first in the country. In order to ensure the smooth communication of the Winter Olympic Games, the Beijing Municipal Communications Administration has also deployed more than 200 5G base stations in local Winter Olympic venues and supporting facilities. 5G not only empowers thousands of industries to sail the future, but also weaves a communication network for the Beijing Winter Olympics and Paralympic Games.

In the face of complex construction needs, Beijing's communications industry has made breakthroughs and innovations, and fully met the needs of the event with wisdom and technology: in the Beijing-Zhang high-speed railway, the 5G network with 3.5GHz and high-frequency low-loss leakage cables have achieved high-speed and stable coverage of 5G signals, and the Beijing-Zhang high-speed railway has thus become the world's first high-speed rail with 5G coverage; combined with the demand for 5G indoor coverage, innovative passive room sub-products, developing and supporting 800-3700Mz full-band devices and antennas to meet the requirements of 5G indoor coverage; after repeated exploration, Before and after the planning, modification and improvement of more than ten versions of the program, in the Haituo Mountain at an altitude of 2198 meters to achieve full coverage of 5G signals; in the Capital Stadium to achieve full coverage of 5G signals, downlink bandwidth up to gigabits.

In addition, Beijing's communications industry adheres to the concept of "sharing the Olympic Games", and through a series of transformations, installs the digital trunking equipment of the Winter Olympic Organizing Committee and the public security department and the radio monitoring equipment of the radio management department on the communication tower, so that the "communication tower" becomes a "digital tower", and the overall sharing rate of related communication infrastructure is more than 95%, which greatly reduces repeated investment.

Application innovation, showing science and technology, wisdom, green style

Network foundation, application bloom. Relying on 5G, MEC, millimeter wave and other technologies, 5G cloud broadcasting, ultra-high-definition live broadcasting, 5G smart viewing, smart command and dispatch, smart medical care, smart epidemic prevention, smart security and other applications shined in this Winter Olympics, giving the Winter Olympics wisdom and technology color.

Based on the synergy capabilities of 5G and cloud network, ultra-high-definition cloud broadcasting is convenient for "fans" around the world to enjoy wonderful events; at the "Ice Ribbon" National Speed Skating Hall, Beijing Unicom launched the "5G Smart Spectator", providing users with services such as free viewing of the game, wonderful playback of bullet time, personalized video sharing, etc.; in the "Ice Cube" National Aquatics Center, 5G robot food delivery service in the closed-loop area was realized; handheld "WozhiHu" intelligent epidemic prevention machine can realize identity verification only by ID card. Health code and nucleic acid detection, etc.; the "smart security" platform can transmit the crowd flow data in the venue at the fastest speed, and then display it in the form of a heat map, which is convenient for managers to grasp the number of personnel, make corresponding decisions and take emergency measures in emergency situations.

The super network has laid a solid foundation, the characteristic applications have bloomed wonderfully, and this Winter Olympics will show the style of science and technology, wisdom and green.

In addition to innovative efforts in network construction and business application, the Beijing municipal communications industry also held support drills in the preparatory stage and formulated a thorough and detailed emergency plan to effectively improve the communication support command and dispatch and emergency support capabilities of the Beijing municipal communications industry during the Winter Olympic and Paralympic Winter Games.

On the afternoon of January 5, the Beijing Municipal Communications Administration held a "drill day" communication support drill for the Beijing Winter Olympics. Simulate and rehearse the two major scenarios of the failure of the mobile communication network of a non-competition venue in Beijing and the damage to some communication facilities caused by a freezing disaster in Yanqing area. After the drill began, the Beijing Municipal Communications Administration quickly activated the emergency response mechanism for the Winter Olympics communication support, established a three-level command and dispatch system of "ministry-city-on-site", and set up a mobile command station on the spot to direct the communication support work; in view of the failure of the mobile communication network caused by the damage to the communication line at a non-competition venue in Beijing, the emergency personnel requested coordinated communication support force support through the "Tiantong No. 1" autonomous satellite telephone, and urgently dispatched the small satellite communication vehicles and large emergency communication base station vehicles of various companies. Carry out communication support on the site and take measures to "increase capacity and drainage"; for some communication facilities in Yanqing area damaged by freezing disasters, laser wreckers are dispatched to carry out de-icing operations, and dynamic sound power supply vehicles are used to provide on-site power supply guarantee for power failure base stations; finally, after close cooperation and mutual cooperation of the whole industry, the venues and regional communication networks that have failed have fully recovered smoothly and smoothly.

It seems to be the most extraordinary, as easy as it is but difficult. Under the organization of the Beijing Municipal Communications Administration, the Communications Industry of Beijing Municipality has done its best to fight and march forward, and through careful deployment and scientific innovation, it has successfully implemented the simple, safe and wonderful requirements for running the competition, and brought the "feast" of the international top competition to the people of the world.
