A method of communicating data between a first terrestrial-based device (20A; 70A) and one or more of a plurality of second devices (18A, 18B; 68A, 68B, 72), said plurality of second devices (18A, 18B; 68A, 68B, 72) including one or more terrestrial-based devices (18A, 18B; 68A, 68B), wherein areas wirelessly serviced by each of said plurality of second devices (18A, 18B; 68A, 68B, 72) either overlap or are adjacent, the method comprising: operating said first terrestrial-based device (20A; 70A) and said plurality of second devices (18A, 18B; 68A, 68B, 72) in an overlapping frequency range, each of said plurality of second devices (18A, 18B; 68A, 68B, 72) operating in a time period different from a time period of another of said plurality of second devices (18A, 18B; 68A, 68B, 72), said first terrestrial-based device (20A; 70A) being configured to wirelessly communicate data with one or more of said plurality of second devices (18A, 18B; 68A, 68B, 72), wherein each time period is separated from an adjacent time period by a guard time interval during which no second device (18A, 18B; 68A, 68B, 72) operates, said guard time interval having a maximum duration corresponding to a maximum time delay a signal takes to propagate a distance between each of said plurality of second devices (18A, 18B; 68A, 68B, 72) to associated serviced areas and a minimum duration corresponding to hardware switch-over time; said first terrestrial-based device (20A; 70A) monitoring the signal strength of a received data signal from one of said plurality of second devices (18A, 18B; 68A, 68B, 72) and comparing the signal strength of the received data signal to the strength of data signals received from surrounding areas serviced by remaining devices in said plurality of second devices (18A, 18B; 68A, 68B, 72); and, shifting communications with the first terrestrial-based device (20A; 70A) to the second device (18A, 18B; 68A, 68B, 72) with the strongest signal. operating said first terrestrial-based device (20A; 70A) and said plurality of second devices (18A, 18B; 68A, 68B, 72) in an overlapping frequency range, each of said plurality of second devices (18A, 18B; 68A, 68B, 72) operating in a time period different from a time period of another of said plurality of second devices (18A, 18B; 68A, 68B, 72), said first terrestrial-based device (20A; 70A) being configured to wirelessly communicate data with one or more of said plurality of second devices (18A, 18B; 68A, 68B, 72), wherein each time period is separated from an adjacent time period by a guard time interval during which no second device (18A, 18B; 68A, 68B, 72) operates, said guard time interval having a maximum duration corresponding to a maximum time delay a signal takes to propagate a distance between each of said plurality of second devices (18A, 18B; 68A, 68B, 72) to associated serviced areas and a minimum duration corresponding to hardware switch-over time; said first terrestrial-based device (20A; 70A) monitoring the signal strength of a received data signal from one of said plurality of second devices (18A, 18B; 68A, 68B, 72) and comparing the signal strength of the received data signal to the strength of data signals received from surrounding areas serviced by remaining devices in said plurality of second devices (18A, 18B; 68A, 68B, 72); and, shifting communications with the first terrestrial-based device (20A; 70A) to the second device (18A, 18B; 68A, 68B, 72) with the strongest signal.
