Embodiment Construction

[0024] In the exemplary embodiment, aircraft 12 is an airliner carrying hundreds of passengers, each using wireless data connection 14 between antenna 16 of aircraft 12 and antenna 18 of ground station 20 via, for example, a smartphone or tablet computer. The antennas 16, 18 are E-band antennas whose main transmit / receive direction is electronically beamforming. Passengers on board the aircraft 12 can receive the data acquired by the antenna 16 on their terminals and eg via WLAN. The data transmission 14 takes place in the E-band, ie in the frequency range from 60 GHz to 90 GHz.

[0025] Antenna 18 of ground station 20 transmits and receives data for data transmission 14 at an angle of approximately 30 degrees above horizontal plane 22 . According to the invention, said angle α cannot be smaller than 5 degrees. The antenna 18 of the ground station 20 will not transmit and receive data at an angle below 5 degrees (main transmit direction). With electronic beamforming, the pr...

Abstract

A device for air-to-ground communication between an aircraft (12) and a ground station (20), said aircraft (12) and said ground station (20) each comprising antennas (16, 18) for directional radio data transmission (14), characterized in that the data transmission (14) is performed in a frequency band from 60 GHz to 90 GHz and that the antenna (18) of the ground station (20) transmits and receives data exclusively in a range of angles alpha of at least 5 degrees in the upward direction relative to the horizontal plane (22).

Description

technical field [0001] The invention relates to a method for data transmission between an aircraft and at least one ground station. Background technique [0002] Data transmission between aircraft and ground stations is important, especially in the field of passenger aviation. There is an increasing need for data transmission technologies that can be used to enable passengers on board an aircraft to make phone calls or surf the Internet. In this document, aircraft is understood to include, inter alia, airplanes, helicopters and spacecraft. [0003] In the data communication between the ground station and the aircraft, it is difficult to satisfy a large number of passengers with sufficient bandwidth for data communication. Contents of the invention [0004] It is an object of the present invention to provide an improved device for data transmission between at least one ground station and an aircraft, and a corresponding method. [0005] The data transmission between the ...
