Air to ground network for broadband access to aerial platforms

摘要

A terrestrial communications network for providing broadband internet access to aerial platforms is described. In some embodiments, the cell site sector communications equipment comprises of at least two radio modules and two antenna apertures, the cell site transmits data to an aerial platform on only one antenna aperture, but receives from the aerial platform on all antenna apertures. In some embodiments, the cell site communications equipment divides each of the N data packet streams destined to N aerial platforms into multiple data packet sub-streams and sends each data packet sub-stream of an aerial platform on a different antenna aperture using a different frequency channel or antenna polarization, forming N beams from each antenna aperture, one beam toward each aerial platform.
