Starlink is SpaceX’s plan for satellite internet. To reduce latency that we see today they plan to use a series of low and very low-level ‘meshes’ that use lasers to communicate with each other.
Potentially it means very fast internet everywhere, which is essentially a license to print money. It even has the capability of being faster than existing ground fiber optics. By using SpaceX reusable launchers the economics of 1000 small satellites becomes possible.
Prof. Mark Handley of UCL did a video of how it could work (with weird computer voice, but whatever), with paper here. Interesting stuff indeed:
A log cabin and fast internet. Cool.
