How Aalyria’s laser tech sent 100Gbps internet across 40 miles

Aalyria, a Google spin-off, has demonstrated a remarkable breakthrough in internet connectivity using its Tightbeam laser communication system. This system successfully transmitted 100 Gbps internet across a 40-mile (65-kilometer) stretch between two mountaintops in Northern California.

This achievement marks a major step forward in free-space optical communications, offering high-speed data transmission far beyond current capabilities. The test link remained operational for weeks, overcoming atmospheric challenges such as turbulence, varying visibility, and wind.

CEO Chris Taylor highlighted the system’s resilience through adaptive optics and proprietary correction algorithms, which ensure consistent, high-quality data flow over long distances.

How does Tightbeam sustain high-speed internet through air over long distances?

Tightbeam uses special light technology and advanced methods to resolve problems caused by the atmosphere, keeping the data accurate. Its design enables operations up to 75 kilometers for ground-to-ground links and even further in ground-to-air scenarios.

This capability far exceeds typical limits seen in free-space optical systems, which struggle with weather and environmental factors.

The system's tracking algorithms continuously adjust to maintain alignment, ensuring a stable connection even when external conditions fluctuate. This allows Tightbeam to deliver a stable 100 Gbps internet connection reliably across vast spans of open air.

Did you know?
Aalyria's Tightbeam technology evolved from Google's Project Loon innovations, transforming balloon-based internet efforts into laser-based high-speed data transmission.

What innovations enable Aalyria’s 100 Gbps transmission to beat atmospheric challenges?

Innovative adaptive optics dynamically correct distortions caused by atmospheric turbulence. These corrections are essential for preserving the integrity of the laser beam and preventing data loss.

The technology also integrates precision tracking to keep the laser beams aligned over the entire 65-kilometer link. Additionally, Aalyria's proprietary algorithms modify transmission parameters in real-time to adjust for changing weather conditions and visibility.

This optimization maintains speed and connection quality, even under adverse environmental pressures, distinguishing it from other optical communication solutions.

Aalyria’s laser tech transforms connectivity in remote and maritime environments

Beyond terrestrial testing, Aalyria demonstrated the system's efficacy in maritime conditions at the Naval Research Laboratory. Simulated sea tests showed Tightbeam sustaining data transmission on a moving ship, with rapid reacquisition after brief disruptions due to vessel motion.

This performance supports Aalyria's $7 million Navy contract for secure, over-the-horizon naval communication. These maritime features show that the system is adaptable and strong, ensuring better connections for naval operations and remote areas where regular infrastructure isn't feasible.

Tightbeam’s breakthrough offers faster, farther internet than existing optical links

Emerging from Google’s discontinued Project Loon, Aalyria repurposed atmospheric communication innovations into laser technology. Tightbeam starts at 100 Gbps speed and scales up to 400 Gbps per channel, making it substantially faster and more versatile than legacy optical systems.

With partnerships including the Defense Innovation Unit and European Space Agency, Aalyria’s technology is poised to revolutionize internet access, especially in underserved or difficult-to-reach regions. This breakthrough signals a future of ultra-fast, reliable broadband without the need for physical cables or satellites.
