5G remote rescue, high-speed download of large files, network blindness... 5G is bringing a new experience to ice and snow sports. In the 5G Capital ice and snow walking activity held from December 13 to 14, the reporter learned from Beijing Unicom that the core area of the Yanqing Competition Area of the Winter Olympic Games has achieved 5G no dead end coverage.
When moving at high speed in a vehicle, many people may have experienced that the internet speed of mobile phones is as slow as cattle. On the Jingli Expressway from the city to Yanqing Winter Olympic Village, 5G networks have solved this pain point. The reporter tried to use two mobile phones of the same model to download files on 4G and 5G networks in the car. When downloading a mobile game of about 1.5GB, the mobile phone under the 5G network takes less than 10 seconds to download, and at this time, the download process of the same mobile game in the mobile phone under the 4G network is only about one-fifth. It is reported that the Jingli Expressway is the first 5G expressway in Beijing to achieve full-band coverage.
"Ding! Identify passed. "At the entrance to the Alpine Ski Centre, staff can simply brush their faces to complete temperature registration and health checks. It is reported that this "Wozhi Care" equipment realizes the recognition and integration of various information such as temperature measurement, face recognition, and itinerary code registration through the 5G high-speed network, improving the speed of the venue staff in and out, and providing guarantee for the high-speed operation of the venue.
Who is better than the athletes in the snow field? Such information is obviously difficult to discern with the naked eye. The communication technicians who are conducting the communication support inspection work of the Winter Olympics on the spot revealed that on the alpine skiing field, the timing scoring cables have been laid from the peak departure area to the end area, which can really report the departure speed, instantaneous speed, and speed of each stage of the athletes in real time and use it for later data analysis.
The national alpine ski center has a pistes drop of about 900 meters, setting a record for the highest snow track drop in China. In this case, alpine skiers need to slide at a speed of up to 140 kilometers per hour, the danger is self-evident, and the transport and treatment of the injured need to overcome the challenges of the steep track and the difficult rescue. Zhang Jia, director of the Office of the Beijing Unicom Winter Olympics, said that Unicom equipped dozens of alpine ski doctors in the arena with a small 5G monitor. Once an athlete is injured and other unexpected situations, when the ski doctor carries out initial rescue, the 5G monitor worn by the ski doctor will automatically transmit the injured person's picture to the medical platform in real time, and the experts on the medical platform can consult and guide through the clear video screen transmitted by 5G to win time for rapid treatment.
Walking into the National Bobsleigh Center Circuit "Snow Dragon", walking along the running area and the side of the track, the reporter saw that every few tens of meters there was a white ball the size of a leather ball. According to the staff of China Unicom, this small round ball is a device that provides a virtual private network for the on-site media, the private network is not affected by the public network, when the media shoots the wonderful moments of the athletes, in the moment of completion of the shooting, the pictures have been synchronously transmitted to the servers of the media. Ensure the rapid transmission of media information, so as to help viewers see fresh and real-time event information in the first place.
What should I do if, in extreme circumstances, there is an emergency need such as network congestion in the arena? At the scene of the Yanqing Competition Area, the reporter saw a "mini base station" the size of a vase. According to the staff, only need to plug this small device called 5G CPE into the power supply, it can quickly provide high-speed 5G Internet Wi-Fi signals for the surrounding areas, and carry out network "blindness".
In addition to the 5G communication guarantee in the arena, in the mountainous areas around Yanqing, villagers will also experience better and better 5G signals in the "post-Winter Olympic period". The relevant person in charge of Beijing Unicom revealed that in addition to the original 5G mainstream network band, China Unicom has also begun to deploy 5G low-frequency network bands in Beijing this year to further achieve wide coverage of 5G signals in mountainous areas.
