5G will take to the sky. The Civil Aviation Administration of China (hereinafter referred to as the Civil Aviation Administration) has officially released the "China Civil Aviation New Generation Aviation Broadband Communication Technology Roadmap" (hereinafter referred to as the "Roadmap"). Issues such as navigation safety and smart aviation applications. This also means that the highly anticipated 5G ATG (Air To Ground ground-to-air broadband communication) is about to "take off".


There are two main ways to surf the Internet in the air, one is satellite communication, and the other is ATG ground-to-air broadband communication. The two complement each other to form the future of smart aviation.


In the face of the last "virgin land", in recent years, all parties in the industry chain have taken active actions. From communication equipment vendors, network operators to aviation service providers, one after another is running the new track of aviation Internet.



Civil Aviation will "hand in hand" 5G


Recently, Yunnan Lucky Air and Xinjiang Urumqi Airlines each have two passenger planes to complete the LAN upgrade, and their first "digital cabin" flights that can provide on-board WiFi service have been flown successively. , So that passengers have more entertainment options in the air besides sleeping, listening to music, and reading magazines. However, to make the dream of on-board office work into reality, it still needs the vigorous advancement of 5G ATG.


The Civil Aviation Administration recently released a roadmap to vigorously promote the application of a new generation of aviation broadband communications, and build a civil aviation 5G network that combines public and private use. "This is the first time that the Civil Aviation Administration has clearly proposed a systematic implementation path for the application of a new generation of aviation broadband communication technology represented by 5G in China's civil aviation." At the regular press conference that day, Zhang Ruiqing, deputy director of the Air Traffic Management Office of the Civil Aviation Administration Said.


The new generation of aviation broadband communication technology is a key technology that promotes the digital transformation of the civil aviation industry and empowers "smart civil aviation." At present, the application scenarios of the new generation of aviation broadband communication technology in the field of civil aviation mainly include: the special aviation network on the airport surface used by aircraft and vehicles in the airport flight area, the public network used by passengers in the terminal, and the open space used by the front cabin of the aircraft during the flight phase. Communication network, and the air Internet used in the rear cabin, etc.


Establish a technical standard system and equipment R&D application system such as 5G AeroMACS, 5G LDACS, 5G ATG and 5G public network of China Civil Aviation, which can provide 5G public network and private network combination and safety A solution that combines communication and non-safety communication will enable 5G to truly empower smart civil aviation and promote the high-quality and safe development of civil aviation.

To solve the problem of slow WiFi network speed on board, civil aviation will accelerate the evolution and upgrade of network infrastructure from three aspects: First, upgrade traditional satellite communication technology to high-throughput satellites Communication technology; the second is to combine the new 5G infrastructure to upgrade the ATG communication system from 4G to 5G; the third is to optimize the existing network structure and enhance network coverage.


Beidou "pocket bottom" open ground cloud network security


In the map of the open-ground cloud network industry, the choice of the technology path of the world-earth interconnection is very important. From the perspective of major global markets, ATG and satellite aircraft Internet complement each other, and it has become the consensus of the industry that ATG is the main land route in the mainstream market. The main reason why ATG has become the mainstream is that under the same coverage area of land routes, ATG has larger bandwidth, lower cost and better experience.


Compared with the use of 4G base stations, in the 5G era, the use of ATG for flights over land can get a larger bandwidth.


Li Xin, deputy director of the Technical Center of the Air Traffic Management Bureau of the Civil Aviation Administration of China, discussed the application of Beidou system in the field of civil aviation at the 2020 (2nd) Civil Aviation Transportation Management Science and Technology Exchange Conference Outlook. The future development of air traffic control technology requires innovation with independent intellectual property rights, which lays the foundation for the application of Beidou system in the field of civil aviation. Li Xin said that China's civil aviation is an important area for the Beidou system to go global and serve the world. Promoting the application of the Beidou system in China's civil aviation field has important strategic significance for both China's civil aviation and the Beidou system itself.


For China’s civil aviation, the use of the Beidou system provides a technically absolutely safe bottom line, legally and logically, completely solves the safety risk of China’s civil aviation using satellite navigation technology. .

In general, the civil aviation system should serve the overall value of the Beidou system's global application. The ultimate goal is to build a GNSS technology application system with Beidou as the core, and promote satellite-based positioning and navigation. The construction of a new generation of air navigation system with timing technology as the core.



All parties in the 5G industry chain "rush to the sky"


Markets and Markets, the world’s second largest market research institution, pointed out in its latest report that by 2021, the global aviation 5G market is expected to reach 500 million U.S. dollars. By 2026, One data will increase to 3.9 billion US dollars, during which the compound annual growth rate will reach 52.7%.


In recent years, network operators such as China Telecom, communications equipment vendors represented by ZTE, and many airlines have entered the 5G+ smart aviation industry chain.
