Zhongxin Finance, January 21st. On the 21st, the "Implementation Plan for the Construction and Application of Broadband Mobile Communication in Aviation 5G Airport Scenes" was announced.
Regarding the safety of "aviation 5G", Chen Xiangyang, deputy director of the Air Traffic Management Industry Management Office of the Civil Aviation Administration, said that "aviation 5G" will not sacrifice or weaken safety as the price, and similar situations that affect aircraft radio altimeters will not occur.
Chen Xiangyang said that the application of 5G in civil aviation also adopts a combination of secure and non-secure communications according to different scenarios, which is not exactly the same as the 5G network we use on mobile phones every day.
For security communications, such as the "aviation 5G" mentioned in the "Implementation Plan for the Construction and Application of Broadband Mobile Communications in Aviation 5G Airport Surfaces", it is completely isolated from the 5G network constructed and deployed by telecom operators, and there is no sharing relationship.
According to Chen Xiangyang, the "Implementation Plan for the Construction and Application of Broadband Mobile Communication in Aviation 5G Airport Scenes" is mainly aimed at the airport airside scene, and is used to realize the efficient and coordinated operation of the airport flight area. The core technology used is 5G AeroMACS.
This technology has several important features: first, it is based on the civil aviation dedicated network, second, it uses aviation dedicated frequencies, and third, it meets the requirements of aviation safety communication level.
These characteristics determine that its use needs to strictly comply with the relevant requirements of the International Civil Aviation Organization, that is, the frequency should be separated from the frequency of other public services, and the network should be strictly isolated from the public network. Bearing services should also be relatively independent.
In response to the news that 5G signals in some foreign airports affect the aircraft radio altimeter, Chen Xiangyang said: "The 5G mentioned in it refers to the 5G public network in some specific frequency bands, and the "Implementation Plan for the Construction and Application of Broadband Mobile Communication in Aviation 5G Airports" A similar situation will not happen to aviation 5G'. Please rest assured that any technological innovation and application of civil aviation will not be at the expense of sacrificing or weakening safety. By rationally setting the evolution route and implementation plan of new technologies, safety can be promoted and improved. ."(Finish)
