Light Spectrum Licensing

Key Takeaways

• FCC considers expanding light licensing for mmWave bands.
• Carriers spent ~$2B each on mmWave auctions.
• Satellite firms seek more shared spectrum for ground stations.
• Millimeter wave remains underused by cellular networks.
• Verizon may leverage Starry to expand outdoor mmWave use.

Summary

The FCC is weighing a "light licensing" approach that would let satellite operators register additional ground stations in the upper‑microwave (mmWave) bands, a spectrum currently held by major cellular carriers. AT&T, T‑Mobile and Verizon each spent roughly $2 billion acquiring 24‑50 GHz licenses, yet the bands have seen limited cellular deployment due to signal blockage and low consumer demand for ultra‑fast speeds. Satellite firms argue that shared use would alleviate congestion as the satellite constellation market expands, while carriers fear revenue loss. Analysts expect the FCC to favor broader sharing, given the carriers’ under‑utilization of the spectrum.

Pulse Analysis

The FCC’s light‑licensing proposal targets the 24‑50 GHz millimeter‑wave range, a segment traditionally earmarked for 5G and future 6G services. By simplifying the registration process for new satellite ground stations, the agency hopes to reduce administrative barriers and promote more efficient spectrum utilization. This move reflects a broader regulatory trend toward flexible, shared‑use frameworks that accommodate the rapid growth of low‑Earth‑orbit constellations, which require high‑capacity links to terrestrial gateways.

Cellular giants AT&T, T‑Mobile and Verizon invested roughly $2 billion each to secure these high‑frequency blocks, yet real‑world deployments have struggled with signal attenuation caused by buildings, foliage, and even human bodies. Early 5G rollouts demonstrated impressive peak speeds but failed to attract mass consumer upgrades, leaving large swaths of mmWave spectrum idle. Verizon’s recent acquisition of Starry, a broadband provider that has built a modest outdoor mmWave network, hints at a possible strategy to monetize the bands, but the company still faces significant capital and coverage challenges.

For satellite operators, broader light‑licensing access promises a cost‑effective path to expand ground‑station density, essential for delivering low‑latency broadband from constellations such as Starlink and OneWeb. Increased spectrum sharing could also set a precedent for future FCC auctions, encouraging collaborative models where multiple services coexist in the same frequency slice. Ultimately, the outcome will influence investment decisions, competitive dynamics, and the pace at which next‑generation connectivity reaches both urban and remote markets.
