I'm addressing your point that it's a solved problem. The issues around making high bandwidth data interconnects are not just "straight bandwidth". I'm explaining that there are fundamental interconnections between bandwidth and SNR that make large bandwidths harder to build at sufficient SNR: https://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise https://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise The iridium satellite receivers use low-gain antennas, so reception is limited to small bandwidths. This means they don't care where the satellites are. New technology will enable high-gain antennas that can track the motion of satellites, enabling much higher channel rates.
