SAN FRANCISCO — In a technical forum published on Friday, January 9, 2026, Mahesh Krishnaswamy, the founder and chief executive officer of Taara, argued that the industry’s fixation on orbital satellite constellations may be overlooking a more efficient terrestrial solution.
While the expansion of Low Earth Orbit (LEO) networks has dominated the connectivity narrative for the past five years, Krishnaswamy suggests that Wireless Optical Communication (WOC) is quietly providing the high-capacity backbone required to bridge the global digital divide without the inherent limitations of space-based infrastructure.
The Dilution of Orbital Capacity
The allure of the satellite industry has evolved significantly since the launch of Telstar 1 in 1962. Today, the orbital environment is populated by over 10,000 active satellites, yet the fundamental physics of delivering data from space remains a challenge for high-density requirements. The primary issue cited in the forum is the dilution of bandwidth. When a satellite provides coverage to a large geographic footprint, the total available capacity is shared among every user within that cell. As more users connect, the individual throughput drops, often resulting in a degraded experience that struggles to support modern, data-intensive applications.
Terrestrial WOC, often referred to as Free Space Optics, avoids this dilution by utilizing narrow, point-to-point beams of light. Rather than broadcasting a signal over thousands of square miles, these invisible highways of light transmit data directly between two terminals. This architectural difference allows for dedicated bandwidth that typically reaches 20 Gbps or higher, matching the performance of physical fiber-optic cables but without the prohibitive cost and time associated with digging trenches or laying undersea lines.
Navigating the Atmospheric and Strategic Divide
A significant portion of the debate surrounding terrestrial versus orbital connectivity centers on reliability and deployment speed. Satellite operators often highlight their ability to reach remote regions where terrestrial infrastructure is non-existent. However, the forum points out that the “last mile” of connectivity is frequently where satellite links fail to meet economic or technical expectations due to high latency and hardware costs. Wireless optical terminals can be deployed on existing structures, such as cell towers or rooftops, in a matter of days.
While critics of optical communication often point to atmospheric interference—such as fog, rain, or dust—as a primary weakness, recent advancements in automated tracking and adaptive transmission have mitigated these risks. These systems now use sophisticated algorithms to adjust the beam in real-time, maintaining a stable link through most weather conditions. This makes the technology a viable alternative for urban and suburban environments where LEO capacity is most likely to be strained by high demand.
The Shift Toward Hybrid Infrastructure Models
The long-term outlook for global connectivity is increasingly viewed as a hybrid model rather than a winner-take-all competition. As the industry moves deeper into 2026, the normalization of active defense and the pursuit of sovereign-commercial technical convergence are driving governments and enterprises to seek redundancy. Satellites will likely remain the preferred choice for maritime, aviation, and extremely isolated military outposts. Conversely, for the billions of people living in areas where fiber is too expensive to install but demand is too high for satellite capacity, terrestrial light beams are becoming the primary solution.
Infrastructure economics are also shifting. The cost of launching and maintaining a mega-constellation involves massive capital expenditures and frequent replenishment cycles as satellites deorbit. Terrestrial optical systems offer a more sustainable financial model with lower operational overhead and a smaller environmental footprint. By focusing on these terrestrial highways of light, providers can offer fiber-like speeds to underserved communities, ensuring that the digital economy remains accessible regardless of a region’s geographic or economic constraints.
