Unfortunately not ready for prime time yet, optical beamforming today is only a few degrees steerable angle and single beam. Also low power and poorly focused.

- JumpCrisscross 4y ago> not ready for prime time yet Totally agree. But the frontier is advancing thanks to LiDAR. And in the meantime, the advantages of laser relay and downlink are vast enough to make mechanical actuation worth it. Particularly for unboosted birds in LEO.
- georgeg23 4y agoCurious how LiDAR tech could be used for high speed communication? At best that is time-multiplexing, not multiple parallel beams of information?
