A method and
system for a plurality of airplanes in flight to receive from and send to a plurality of ground stations broadcast and communication signals through a single or a plurality of geostationary satellites, wherein at least the mobile link between said airplanes and said
satellite, uplink or downlink, uses the
high frequency radio
waves at 17 GHz or higher, such as Ka-band. The fixed link between said
satellite and said ground stations may use any radio frequencies below the frequencies used to communicate between the
satellite and the aircraft. The lower frequencies tend to be less susceptible to rain attenuation and hence suitable for closing the fixed broadcast and
communication link. Frequencies such as C-band or Ku-band, or even Ka-band, are applied between satellite and ground such that the available
link margin is sufficient to overcome rain attenuation at said ground stations. Said satellite carries a plurality of transponders that may include a plurality of frequency
converters to enable the conversion between different frequencies. Said satellite generates a plurality of spot beams, shaped or unshaped, which collectively cover the flight routes of said airplanes, preferably the geodesic path between two highly populated regions.
