Embodiment Construction

[0033] The detailed description, given below in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configurations that implement the concepts described herein. The detailed description includes specific details in order to provide a thorough understanding of various concepts. However, one skilled in the art will recognize that the concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts.

[0034] The spectrum available for Internet communications via land-based air-to-ground (ATG) systems to aircraft is limited for practical and economical reasons. Providing seamless communication with aircraft flying over a large area at high altitudes, such as the continental United States, involves spectrum available over that large area. That is, the spectrum allocated to...

Abstract

A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna includes adjusting a modulation symbol interleaving and / or forward error correction of an aircraft receiver interface in response to detected interference from an interferer. The method further includes reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and / or forward error correction does not mitigate the detected interference. Another method for interference mitigation may include performing antenna beam-steering away from a geographic (GEO) arc during an aircraft turn. This method further includes reducing an aircraft transmitter transmit power when a signal quality of a forward link is within a predetermined range of a signal quality threshold.
