Abstract
The signal translating repeater is located in the aircraft and enables a traditional ground-based mobile subscriber station to provide wireless telecommunication services to a subscriber in both the terrestrial (ground-based) and non-terrestrial regions. The signal translating repeater receives frequency translated cell site cellular signals, comprising cellular radio frequency communication signals from a cell site that are in a mode compatible with ground-based cellular communications but shifted in frequency from the standard ground-based cellular radio frequency communication signals to other radio frequencies that are allocated for non-terrestrial cellular communications. The signal translating repeater automatically translates the received frequency translated cell site cellular signals into the ground-based cellular signals, comprising radio frequency communication signals that are in a mode compatible with ground-based cellular communications, used by the ground-based mobile subscriber stations located in the aircraft.
