Alphabet wants to deliver Internet access via laser beams

Alphabet’s X Lab has cooked up yet another Internet connectivity scheme, according to a report from Reuters. Past efforts have involved floating Internet balloons and laying lots of fiber optic cable, but this Internet delivery system sends data over laser beams! This isn’t an experimental system like Project Loon; India’s Andhra Pradesh state government has signed an agreement with Alphabet to bring the technology to millions of people starting next year.

The technology is called “free space optical communication,” and it works exactly the way it sounds: you aim two light beams at each other and communicate through blinking. “Free space” means you’re not using any cable at all and are just communicating through the air over line of sight. Typically this is done with lasers, although for shorter distances it’s possible to use LEDs.
