Communication system for aircrafts with altitude based antenna type selection

摘要

A system and method for providing wireless data communication between a wireless communication system in an aircraft and a stationary communication server outside the aircraft are disclosed. The wireless communication system includes a plurality of antennas, and a router in the aircraft configured to transmit and receive wireless data communication to and from a stationary communication server outside the aircraft through at least one ground base station via at least one of the plurality of antennas. The plurality of antennas includes at least one omnidirectional antenna and at least one directional antenna. The router includes a control unit configured to restrict the wireless data communication to solely occur through the at least one directional antenna the when the current altitude of the aircraft is determined to be above a predefined altitude threshold value.
