Below is a possible roadmap to the orbital internet; reality will certainly vary.

Worth Reading: Satellites and Cellular Backhaul


Elon Musk recently announced that he was going to be providing cellular backhaul from the Starlink constellation of satellites. This makes a lot of sense from a financial perspective in that it avoids the costly wired fiber networks needed to reach rural cell sites.

Worth Reading: Selling Off Transit

Worth Reading: How – And When – Optical I/O Will Make Disaggregated Systems Better


This would have always been a good thing, but as we come to the end of Moore’s Law and transistors are going to start getting more expensive and semiconductor packages are going to get more complex and more costly, too, something has to give.

Worth Reading: A Simulation of the SpaceX, Amazon, Telesat and OneWeb Broadband Satellite Constellations


Over two years ago, an MIT research group ran a simulation of the low-Earth orbit broadband constellations of OneWeb, SpaceX, and Telesat, and last January they repeated the simulation updating with revised constellation characteristics and adding Amazon’s Project Kuiper.
