Abstract
The air-to-ground cellular network for deck-to-deck call coverage provides call coverage to customers who are located in aircraft that are flying within the arrival/departure airspace of an airport by trifurcating the spatial coverage regions or volumes of space to solve the problems of inter-network interference while yielding air-to-ground cellular network coverage at any altitude. Three types of cells are considered: an Outer Cell, an Inner Cell and an Airport Cell. The Outer Cell is a macro cell covering a large volume of space and is one of many cells in the composite air-to-ground cellular network. The Inner Cell is created within an Outer Cell and has at its center an airport. The Airport Cell is a part of the Terrestrial Cellular Network (TCN), created by the present terrestrial cellular operators or service providers.
