Fixed Wireless vs Fiber: The Real Trade-Offs

Why It Matters

Understanding T‑Mobile’s hybrid approach and the regulatory hurdles it faces helps investors, policymakers, and competitors gauge the realistic path to universal high‑speed internet in the United States.

Key Takeaways

• T‑Mobile uses both fixed wireless and fiber to expand coverage.
• Fixed wireless capacity planning prevents service degradation as demand grows.
• Pricing model guarantees no rate hikes, boosting customer satisfaction scores.
• Rising equipment and permit costs challenge fiber rollout across municipalities.
• Policy flexibility needed to balance fiber incentives with cheaper wireless solutions.

Summary

The Unmuted episode pits T‑Mobile’s executive vice president Alan Samson against the growing debate over fixed wireless versus fiber, outlining how the carrier is tackling the nation’s broadband expansion challenge.

Samson explains T‑Mobile’s dual‑technology strategy: a flexible fixed‑wireless network that now reaches 80‑90 million homes and a targeted fiber build‑out. By allocating leftover spectrum on a sector‑by‑sector basis, the company has grown its fixed‑wireless subscriber base 80 % in two years while average speeds have risen 50 %, proving its capacity‑planning model works.

He highlights concrete practices—stopping sales in oversubscribed sectors, offering a price‑guarantee with no ancillary fees, and delivering a Net Promoter Score that tops industry benchmarks. At the same time, he warns that rising equipment costs and fragmented municipal permitting slow fiber deployments, and that policy that rigidly favors one technology could create headwinds.

The discussion signals that operators will need to blend wireless and fiber, keep pricing transparent, and push for streamlined, technology‑agnostic regulations if the U.S. hopes to meet escalating broadband demand without costly delays.

Original Description

Scaling U.S. Broadband: Allan Samson on Fixed Wireless Growth, Fiber Economics, and Policy Risks.

Welcome back to Unmuted, where host Catherine Sbeglia Nin has candid connectivity conversations with leaders shaping the future of wireless. In this episode, Catherine is joined by Allan Samson, Executive Vice President and Chief Broadband Officer at T-Mobile US, for a deep dive into what it really takes to scale broadband across the United States today.

As fixed wireless access (FWA) and fiber expansion accelerate, Allan breaks down the operational realities behind the growth. From managing spectrum assets and network capacity to protecting mobile performance while expanding home broadband, he explains how T-Mobile balances engineering discipline, economics, and customer experience.

The conversation explores T-Mobile’s fallow capacity model, which allocates unused spectrum sector-by-sector to fixed wireless, allowing broadband growth without degrading mobile performance. Despite rapid subscriber growth and rising household data consumption, Allan shares how speeds and performance have continued to improve.

On fiber, he discusses the heavier capital investment, longer deployment timelines, and the importance of capital-light partnerships. He also outlines what T-Mobile has learned competing head-to-head with cable and fiber incumbents, focusing on pricing transparency, eliminating hidden fees, and offering long-term price guarantees.

Finally, Allan highlights one of the most under-the-radar risks to broadband growth: municipal permitting complexity. With fiber deployment requiring approvals across hundreds of municipalities, inconsistent local regulations and resource constraints could slow national expansion. He emphasizes the need for policy flexibility, ensuring fixed wireless, fiber, and other technologies can compete based on economic rationality rather than regulatory favoritism.
