Taara Beam Delivers Fiber-Grade Internet Through the Air

A shoebox-sized laser link is delivering fiber speeds through the air.

Taara, the free-space optical (FSO) venture born from Google X, is at Mobile World Congress in Barcelona unveiling Taara Beam, a compact terminal designed to push gigabit-per-second data across urban air, not fiber cables. The system beams infrared light between rooftops or utility poles, turning the sky into a data conduit. Engineering documentation shows the module weighs 8 kilograms and fits in a footprint roughly the size of a shoebox, yet it can connect buildings a kilometer apart and beyond.

Demonstration footage shows Taara Beam hitting fiber-competitive speeds of up to 25 Gbps with latencies around 50 microseconds. The concept is simple in its metaphor: “Every one of our Taara terminals is like a digital camera with a laser pointer,” says Mahesh Krishnaswamy, Taara’s CEO. The “laser pointer” actively transmits data; the “digital camera” on the opposite end decodes it. The result, at least in controlled demonstrations, is a point-to-point link that sidesteps trenching, permits rapid deployment, and sits atop the city’s existing utility infrastructure.

The technology’s origin is telling. Taara began life as a Google X moonshot aimed at connecting rural sub-Saharan Africa with high-speed links, but Beam turns that mission toward dense urban environments where fiber isn’t fully reaching individual buildings. The system’s open-air path is not a pipe—it's a line of sight, with a laser beam travelling across air rather than glass. In practice, that means the link can be very fast and low-latency, but it also relies on stable alignment and favorable weather.

Technology readiness is currently at the demo and early field-testing stage. Taara Beam is being shown under the “Game Changers” umbrella at MWC, signaling a strong commercialization push but not yet a full-scale deployment footprint. Lab testing confirms that the unit’s core capability is the free-space optical channel: high throughput with minimal delay, provided the pointing and reception maintain their alignment. Demonstration footage confirms the core claim—fiber-like speeds over air in a compact hardware package—but the real-world reliability question remains: can these links survive the city’s wind, rain, haze, and shifting angles caused by tall buildings?

For the wider telecom ecosystem, Taara Beam represents a potential complement to fiber rather than a replacement. Engineering documentation shows that Taara targets the “last mile” or “last few hundred meters” problem in dense urban cores where fiber remains underutilized or unavailable at the building. The company notes a practical opportunity near existing fiber landing points; Google’s own infrastructure near a California landing site served as a tangible example of proximity enabling these free-space hops. In other words, Taara Beam could connect rooftops to existing fiber backbones, reducing the need for trenching and permitting a faster, modular expansion of capacity.

Two practitioner-facing insights stand out. First, weather and line-of-sight geometry are non-trivial constraints. Free-space links can suffer from fog, rain, or even thermal lensing, and maintaining precise pointing—especially across an urban canyon—requires robust auto-tracking and alignment systems. Second, the economics hinge on deployment density and reliability: a 25 Gbps tie is valuable, but only if enough links are in place to justify maintenance, cooling, and safety considerations for infrared transmission in built environments.

In the broader arc of urban connectivity, Taara Beam offers a tangible demonstration of how optical links can accelerate near-term capacity expansion without civil works. It’s a reminder that not every “revolution” needs a new robot arm or a factory-grade drone; sometimes, the future of cities runs on laser pointers and the digital cameras that receive them.
