Abstract:
A method for ground to air communication includes receiving a first pilot signal on a first wide beam from a first ground base station by a first antenna element covering a first range of azimuth angles from an aircraft. Data is received on a directed data beam from the first ground base station by the first antenna element. A second pilot signal is received on a second wide beam from a second ground base station by a second antenna element covering a second range of azimuth angles different than the first range of azimuth angles. A signal strength of the second pilot signal is compared with a signal strength of the first pilot signal. Data reception is switched from the first antenna element to the second antenna element if the signal strength of the second pilot signal is greater than the signal strength of the first pilot signal.
