These two standards were published 2016 and 2017 and are no longer considered to be in widespread use. It is therefore now time for ITS to vote on whether these should be withdrawn.

The standards are for broadband direct Air-to-Ground communications, focusing on equipment using beamforming and fixed pattern antennas. The standards ensure compatibility, efficient spectrum usage, and compliance with the technical requirements set out in the EU’s radio spectrum regulations.

1. Standard for Broadband Direct Air-to-Ground Communications with beamforming antennas

Standard EN 303 316 regulates equipment for Broadband Direct Air-to-Ground Communications in the 1900–1920 MHz and 5855–5875 MHz frequency bands, focusing on the use of beamforming antennas.

Version V1.1.1 (2017-10) covers the essential requirements under Article 3.2 of EU Directive 2014/53/EU.
Version V1.2.1 (2018-04) is a harmonised standard for access to radio spectrum and provides an updated and more detailed specification.

These standards help ensure compatibility and efficient spectrum use in direct communication between aircraft and ground stations.

2. Standard for Broadband Direct Air-to-Ground Communications with fixed pattern antennas

EN 303 339 V1.1.1 (2016-06) regulates equipment for Broadband Direct Air-to-Ground Communications using fixed pattern antennas, operating in the 1900–1920 MHz and 5855–5875 MHz frequency bands.

This harmonised standard covers the essential requirements under Article 3.2 of EU Directive 2014/53/EU and ensures that the equipment meets the necessary technical and safety criteria.

The purpose of the standard was to promote compatibility and efficient spectrum used in direct communication between aircraft and ground stations.
