China Telecom has made a major breakthrough in the aviation scene: enabling phone communications on board aircraft

According to the news on January 19, according to the official official account of China Telecom Satellite, the joint innovation project between the two parties - the "Inflight Network Platform VoWiFi Project" was recently accepted in the airborne simulation environment of Air China.

Based on a simulation environment that is completely consistent with that of civil aviation airliners, ordinary mobile phone terminals can realize functions such as mobile phone authentication, three-network voice, SMS interoperability, and video calls through the in-flight Internet environment in flight mode. The test results are in line with expectations. Users The experience is consistent with the terrestrial 5G network and the effect is excellent.

This marks a major technological breakthrough in the innovative application of "satellite VoWiFi" satellite-ground integration technology in aviation scenarios. It is also an example of China Telecom's "satellite" product system empowering land, sea, air and space. Important scenario-based applications are implemented.

According to reports, aviation VoWiFi, the abbreviation of Voice over WiFi, refers to using WiFi hotspots provided in the aircraft cabin and adopting international standard software protocols to replace traditional mobile phone wireless base stations after passengers activate mobile phone services. Experience the same basic carrier-class services such as voice and text messages as on terrestrial networks.

Currently, my country’s civil aviation requires passengers to have their mobile phones in flight mode during the flight to ensure flight safety. Mobile phones can be used in-flight through the in-cabin Wi-Fi network on aircraft with Internet capabilities. Access to the Internet, but unable to make calls or send text messages.

Aviation VoWiFi can solve such communication needs of passengers, making it possible to make and receive calls and send and receive text messages during the flight, truly extending the user's usage habits on the ground to an altitude of 10,000 meters.

It is worth noting that this technology does not require airlines to install any additional hardware on the aircraft, and passengers do not need to change their mobile phones or download apps. They only need a system upgrade to use China Telecom’s 5G package. Aviation VoWiFi service can be used directly.
