摘要: The airborne radio communications system of the present invention enables an to communicate with ground based cellular radiotelephone system. also keep track location and page it when a call from telephone is received. base station connected upward radiating antennas that form cells. As aircraft flies through cells, relay receives signals relays them radio. If transmitting signals, transmits those station. moves cell cell, handed off next maintain ground.
