Abstract
The disclosure relates to a ground-based wireless cellular communication system providing in-flight broadband mobile communication services. The system includes at least one ground-based base station adapted for generating at least one cell defining a solid angle of space surrounding the base station. The ground-based base station includes an antenna array using two-dimensional-beamforming for generating at least one beam for serving at least one airplane in the space covered by the at least one cell using spatial-division multiple access (SDMA). The disclosure also relates to an airplane equipment for providing in-flight broadband mobile communication services. The airplane equipment includes an antenna for exchange of user data with the ground-based wireless cellular communication system, a transceiver unit connected to the antenna for handling the air-to-ground and ground-to-air communication with the ground-based wireless cellular communication system, and an inside-airplane communication system for distributing the user data to and from terminals within the airplane.
