Abstract
A method of generating a control signal to enable or inhibit a wide variety of applications is provided. The method generally includes the steps of determining the location of a first mobile radio terminal, determining the location of a second mobile radio terminal, comparing the locations of the terminals, and generating a control signal based upon the comparison. The control signal may be generated if the first and second mobile radio terminals are within a specified distance of one another. Alternatively, the control signal may be generated if the first and second mobile radio terminals are separated by at least a specified distance from one another. Additionally, the control signal may be generated if it is determined that the first mobile radio terminal is at a first specified location and the second mobile radio terminal is at a second specified location spacially separated from the first specified location. Further, the control signal may be generated if the first and second mobile radio terminals are at specified locations at a preselect time.
