The Taara chip, developed by Alphabet's X division, is a significant breakthrough in wireless optical link technology. It uses a narrow, invisible light beam to transmit data at speeds of up to 20 gigabits per second over distances of up to 20 kilometers. This technology has the potential to provide high-speed internet connectivity to remote and underserved areas, where traditional fiber-optic cables are not feasible. The Taara chip is smaller and more efficient than its predecessor, Lightbridge, and can be installed in a matter of days, making it an attractive solution for areas where internet connectivity is limited. The technology was originally developed for Project Loon, a now-defunct initiative to provide internet connectivity using balloons. However, the team has continued to work on the technology and has made significant progress in recent years.
