Air to Ground

Direct-Air-to-Ground Communications (DA2GC) system constitutes an application for various types of telecommunication services, such as Internet access and mobile multimedia services, during flights. It aims to provide access to broadband communication services during continental flights.

Currently, most in-flight connectivity uses satellite backhaul. This solution, in addition to being heavy and expensive, presents capacity limitations and high latency, especially for short and medium-haul continental flights.

Air-to-Ground (A2G) LTE utilizes a ground-based cellular system to create a direct link between the aircraft and the ground for broadband IP connectivity without the large-delay hop via a satellite. The ground infrastructure is based on the latest 3GPP global standard for wireless LTE. With a highly efficient air interface and a flat IP network architecture, LTE is an ideal, future-proof platform on which to deploy an A2G network.

A2G LTE is capable of providing download speeds of up to 75 Mb/s to planes and 25 Mb/s from aircraft at distances of 100 kilometers and speeds of 1,200 kilometers per hour, using 2×15 MHz FDD licenses in the Mobile Satellite Service (MSS) S-band.

Field trials with the DA2GC system, specified by ETSI in TR 103 054, were successfully performed in Germany on the 2.6 GHz FDD bands by Deutsche Telecom and Alcatel Lucent in 2013.
