Backhauling femtocell Iuh traffic over BGAN

This paper describes two IP-level architectures for connecting 3G femtocells via Iuh to a femtocell gateway over a BGAN satellite link. These architectures allow femtocells to be deployed in isolated regions where satellite links serve as the only means of communication (e.g. oceanic outposts, deserts, rural regions, disaster areas, etc). Additionally, this paper identifies and describes several techniques to minimize bandwidth usage when backhauling Iuh traffic over the satellite. Finally, the performance of these approaches are presented and some of the main strengths and limitations of the overall system are outlined.
