The project has taken the Free Space Optical Communications technology developed for Project Loon, one of Alphabet's explorations on delivering high-speed internet connections to rural areas whilst using stratospheric helium balloons. Alphabet said that its Project Taara link was operational for 20 days during the test period, where it achieved a signal availability level of 99.9% - meaning that it was practically uninterrupted. The laser system features self-adjustment capabilities that aim to circumvent weather and wildlife elements, which allow the lasers to not only boost the laser strength if required, but also to adjust the output and input laser dishes by up to +/- 5 degrees. The system's current development stage should allows for "a light beam the width of a chopstick accurately enough to hit a 5-centimeter target that's 10 kilometers away."

Project Taara: Alphabet's Laser-based 20 Gbps Communication System Transmits 700 TB Over 5 Km
Alphabet has announced that its prototype implementation of a laser-based communications system, Project Taara, successfully managed to transmit over 700 Terabytes of data over a 5 km distance. The system successfully transmitted the information across the Congo river in the African continent, connecting the towns of Brazzaville (Republic of Congo) and Kinshasa (Democratic Republic of Congo). The system aims to deliver fiber-optic-level communications speed in locations where infrastructure investment cost for a fiber optics solution is economically unfeasible. In this case, Project Taara delivered the high-speed connection where 250 miles of fiber network cabling would need to be laid out to achieve the same effect. It should also allow for cheaper infrastructure development in well-developed cities.The project has taken the Free Space Optical Communications technology developed for Project Loon, one of Alphabet's explorations on delivering high-speed internet connections to rural areas whilst using stratospheric helium balloons.
