Satellite Cell Towers Will Beam 4G to Your Phone – WIRED

Within the next two years, Lynk plans to create a constellation of shoebox-sized satellites that will function as orbiting cell towers. Each satellite will use a modified version of terrestrial cell tower software that corrects for things like the Doppler frequency shift caused by the satellite rapidly passing overhead and the delay from sending a signal to space and back. The satellites operate on a relatively low frequency compared to other communications satellites, which means they can tap into the part of the spectrum used by cell phones on earth. Miller says the company has developed an antenna that is both sensitive and powerful enough to communicate with cell phones on earth, but declined to get into specifics of the technology.
