The Future of Connectivity: How Light Could Replace Radio Waves
The Evolution of Internet Connectivity
Alphabet’s “moonshot factory,” known as X, has always been a hub for innovative and sometimes outlandish projects. One of the most ambitious was Loon, which aimed to deliver internet via high-flying balloons. Although Loon eventually “graduated” from X and was shut down in 2021 due to an unsustainable business model, its legacy lives on in Taara, a project that focuses on delivering high-bandwidth internet via laser beams.
The Birth of Taara
The former Loon engineer Mahesh Krishnaswamy left the project to form a team specifically working on the data transmission part of connectivity. This new venture, Taara, aims to deliver high-speed internet using laser beams, akin to fiber optics without the cables. While the idea isn’t new, Taara has been perfecting its real-world implementations over the past few years.
The Technology Behind Taara
Taara’s technology involves “light bridges” that are about the size of a traffic light. These bridges can transmit data at speeds equivalent to a fiber-optic cable without the need for physical cables. The technology has been successfully implemented in various real-world scenarios, including crossing the Congo River and augmenting the cellular network at the Coachella music festival.
The Potential of Taara’s Technology
Tara’s new generation of technology—a chip—promises to make the system even more viable. This chip will shrink the gadgetry in its light bridges to the size of a fingernail, replacing mechanical gimbals and costly mirrors with solid-state circuitry. This innovation could potentially usher in a new era where light does much of the work that radio waves do today, only faster.
Real-World Applications and Success Stories
Taara’s technology has already been used in more than a dozen countries. One notable success story is the Congo River crossing, where a Taara light bridge provided Kinshasa with nearly equally cheap internet as Brazzaville, which had a direct fiber connection. Another example is the use of Taara’s technology at the 2024 Coachella music festival, where it augmented an overwhelmed cellular network.
The Future of Connectivity: 6G and Beyond
Astro Teller, X’s “captain of moonshots,” and Mahesh Krishnaswamy believe that 6G might be the final iteration to use radio waves. Traditional radio frequency bands are congested and running out of available bandwidth, making it harder to meet our growing demand for fast, reliable connectivity. The answer, as they see it, is light, which could be the key element in 7G.
Expert Insights
Professor Mohamed-Slim Alouini, who has worked in optics for a decade, describes Taara as “a Ferrari” of fiber-free optical. “It’s fast and reliable but quite expensive.” However, the cost could change with Taara’s second-generation offering, which includes a silicon photonic chip that will allow a single laser transmitter to pair with multiple receptors.
The Road Ahead
In the shorter term, Teller and Krishnaswamy hope to see Taara technology used to provide high-bandwidth internet when fiber is unavailable. One use case would be delivering elite connectivity to an island community just offshore or providing high-speed internet after a natural disaster. But they also have more ambitious dreams, envisioning thousands of Taara chips in mesh networks, throwing beams of light, in everything from phones to data centers to autonomous vehicles.
Did You Know?
Taara’s technology can offer 10, if not 100 times more bandwidth to an end user than a typical Starlink antenna, and do it for a fraction of the cost. This could revolutionize internet connectivity, especially in remote and disaster-stricken areas.
