Abstract
The present signal translating repeater is located in an aircraft and provides service to mobile subscriber stations that are located in the aircraft, using the ground-based cellular communication paradigm. The present signal translating repeater converts these ground-based cellular communication signals into signals pursuant to the non-terrestrial cellular telecommunication format and transmits these signals to the non-terrestrial cell site(s) presently serving the aircraft. In this manner, the subscribers in the aircraft can use their existing ground-based mobile subscriber stations in a manner that is consistent with use in communicating with the ground-based cell sites, while the aircraft communicates with the non-terrestrial cell site(s) presently serving the aircraft in a manner that is consistent with non-terrestrial mobile subscriber stations.
