1. A method of transmitting identical data signals from a plurality of transmitters, wherein areas serviced by each of said plurality of transmitters either overlap or are adjacent, comprising: operating said plurality of transmitters to transmit identical data signals on a single channel to a receiver in an overlapping frequency range, wherein each of said plurality of transmitters operates to transmit the identical data signals to the receiver in a time period different from a time period in which another of said plurality of transmitters operates to transmit the identical data signals to the receiver. 2. The method according to claim 1, wherein the time period during which each of said plurality transmitters operates and the time period during which another of said plurality of transmitters operates are separated by a guard time interval during which neither one operates. 3. The method according to claim 2, wherein the guard time interval comprises a maximum guard time interval corresponding to a maximum time delay a data signal takes to propagate a distance between each of the plurality of transmitters to corresponding serviced areas and a minimum guard time interval corresponding to hardware switch over time. 4. The method according to claim 1, wherein said guard time interval is selected so that there is substantially no overlap between the time period during which each of said plurality of transmitters operates and the time period during which another of said plurality of transmitters operates. 5. The method according to claim 1, further comprising operating a receiver in the overlapping frequency range, wherein the receiver monitors data signal strength of a received data signal from one of said plurality of transmitters and compares the data signal strength of the received data signal to strength of data signals received from surrounding areas serviced by remaining transmitters in said plurality of second transceivers. 6. The method according to claim 5, wherein the receiver locks on a strongest data signal. 7. The method according to claim 5, wherein the receiver integrates the identical data signals transmitted by each of the plurality of transmitters. 8. The method according to claim 5, wherein one of said plurality of transmitters is a satellite and said receiver is configured to receive a data signal from said satellite and to receive data signals from remaining transmitters in said plurality of transmitters. 9. The method according to claim 8, wherein said remaining transmitters are terrestrial and are configured to receive the data signal from said satellite. 10. The method according to claim 8, wherein the satellite is assigned a time period and the remaining transmitters are assigned remaining time periods. 11. The method according to claim 10, wherein each of the remaining transmitters synchronizes to the time period assigned to the satellite and generates its time period start time. 12. The method according to claim 8, wherein the remaining transmitters are timed based upon a signal propagation time delay from the satellite to the ground. 13. The method according to claim 8 wherein the receiver locks on a strongest data signal among signals transmitted by the satellite and the remaining transmitters. 14. The method according to claim 8, wherein the receiver integrates identical data signals received from the satellite and each of the remaining transmitters in the plurality of second transmitters. 15. The method according to claim 1, wherein at least two transmitters in said plurality of second transmitters are terrestrial. 16. The method according to claim 1, wherein said plurality of second transmitters are terrestrial. 17. The method according to claim 1, wherein said plurality of second transmitters are controlled by a same control complex. 18. A terrestrial-based device for communicating data signals in a network, comprising: a terrestrial-based transceiver configured to wirelessly communicate with one or more base stations and/or satellites from a plurality of base stations and/or satellites that are configured to wirelessly service overlapping or adjacent areas, each base station and/or satellite being configured to operate in a time period different from a time period of another base station and/or satellite,wherein the terrestrial-based transceiver is configured to communicate with a base station or satellite from the plurality of base stations and/or satellites during the time period in which that base station or satellite operates,wherein the terrestrial-based transceiver communicates data signals with the one or more base stations and/or satellites in an overlapping frequency range. 19. The terrestrial-based device of claim 18, wherein a time period at which a base station or satellite from the plurality of base stations and/or satellites operates is unique and separated from an adjacent time period at which another base station or satellite from the plurality of base stations and/or satellites operates by a guard time interval during which no base station or satellite operates. 20. A terrestrial-based device for communicating data signals in a network, comprising: a terrestrial-based transceiver configured to wirelessly communicate with one or more base stations and/or satellites from a plurality of base stations and/or satellites that are configured to wirelessly service overlapping or adjacent areas, each base station and/or satellite being configured to operate in a time period different from a time period of another base station and/or satellite, the terrestrial-based transceiver being configured to operate in an overlapping frequency range with the plurality of base stations and/or satellites,wherein each time period is separated from an adjacent time period by a guard time interval during which no base station or satellite operates, the guard time interval having a maximum duration corresponding to a maximum time delay a signal takes to propagate a distance between each base station and/or satellite to associated serviced areas and a minimum duration corresponding to hardware switch-over time, andwherein the terrestrial-based transceiver is configured to monitor signal strength of a received data signal from one of the base stations and/or satellites and compares the signal strength of the received data signal to strength of data signals received from surrounding areas serviced by remaining base stations and/or satellites from the plurality of base stations and/or satellites and selects the base station or satellite with the strongest signal for communication. 21. A system for communicating data signals in a network, comprising: a base station configured to wirelessly communicate with a terrestrial-based device, the base station being one of a plurality of base stations and/or satellites configured to wirelessly service overlapping or adjacent areas, the base station being configured to operate in a time period different from a time period of another base station and/or satellite from the plurality of base stations and/or satellites, the base station being configured to operate in an overlapping frequency range with the terrestrial-based device,wherein the time period at which the base station operates is separated from an adjacent time period associated with another base station and/or satellite from the plurality of base stations and/or satellites by a guard time interval during which neither the base station nor another base station and/or satellite operates, the guard time interval having a maximum duration corresponding to a maximum time delay a signal takes to propagate a distance between each base station and/or satellite from the plurality of base stations and/or satellites to associated serviced areas and a minimum duration corresponding to hardware switch-over time,wherein the base station is configured to monitor data signal strength of a received data signal from the terrestrial-based device and to compare the data signal strength of the received data signal to strength of signals received by remaining base stations and/or satellites from the plurality of base stations and/or satellites from said terrestrial-based device, andwherein the base station is configured to take on communication with the terrestrial-based device when the base station is the base station and/or satellite that receives the strongest data signal from the terrestrial-based device.
