In May 2021, the Civil Aviation Administration of China (CAAC) released the “Roadmap for New Generation Aviation Broadband Communication Technology for Civil Aviation in China”, which clarifies the construction and application of new generation aviation broadband communication system represented by 5G. To this end, China Telecom will promote the construction of a customized 5G network for smart civil aviation, and realize “cloud-network integration and on-demand customization” through “5G + edge + cloud + X”, so that 5G technology can take root in the civil aviation industry.
To truly address the urgent needs of civil aviation passengers for Internet access services, China Telecom has invested 100MHz of telecom frequencies and 10MHz of airline mobile frequencies, and adopted a hybrid networking approach, combined with Tianyi cloud resources to provide a customized 5G ATG air-to-ground cloud network for China’s civil aviation. At present, China Telecom has started the construction of 5G ATG network, and plans to complete the network construction in the third quarter of this year to realize the network coverage of national airlines and complete the airworthiness of airborne equipment at the same time. After the network is completed, a single aircraft will have a peak bandwidth of up to 1Gbps, enabling passengers to enjoy a high-speed bandwidth Internet experience at 10,000 meters in the air.
According to IT House, China Telecom has opened three ATG trial routes from Beijing to Chengdu, Beijing to Shanghai and Beijing to Guangzhou at the end of 2020, and will realize the world’s first 5G ATG network for official commercial use in 2021. China Telecom said that 5G ATG can perfectly support a variety of services and provide air Internet and intelligent civil aviation services for the whole civil aviation, which can realize intelligent entertainment services such as live video broadcasting, intelligent cabin services such as booking and changing tickets, and intelligent travel services such as baggage tracking, and will also realize intelligent flight applications such as real-time QAR, intelligent security applications such as cabin video, and intelligent operation control applications such as ground command coordination. The network will also enable intelligent flight applications such as real-time QAR, intelligent security applications such as cabin video, and intelligent operation and control applications such as ground command coordination. China Telecom’s 5G custom network can also cover airports, air traffic control, airlines, supervision and other operational scenarios, and innovate more industry applications to serve the construction of civil aviation systems.
Zhang Zhiyong said that currently, China Telecom has reached a consensus with Long Dragon Airlines as the first user to implement the operation of 5G ATG network for the whole fleet. China Telecom will work with airlines to promote 5G ATG cooperation, improve the air Internet ecology and form a win-win situation for all parties.
IT Home learned that on May 14, Zhang Ruiqing, deputy director of the Civil Aviation Administration’s air traffic management office, responded to the “slow in-flight wifi network speed” by saying that the relatively slow wireless network rate on planes is mainly due to institutional limitations in communication technology. “To solve this problem, the bureau will upgrade the traditional satellite communication technology to high-throughput satellite communication technology; secondly, combined with the new 5G infrastructure, the ATG communication system will be upgraded from 4G to 5G communication technology; thirdly, the existing network structure will be optimized to enhance network coverage.”
