During the 1990s, many believed satellite phones were the future of mobile communications. Rapidly expanding terrestrial cellular networks gobbled up most of the market instead. Still, satellite phones retained some technical advantages over cellular ones, principally in remote or rugged areas that are difficult to cover economically with cell towers. Now the TerreStar Genus smart phone is combining the best of both worlds, using a cellular connection when available and tapping into a satellite feed when people wander out of range of a cell tower.
