2025 Broadband Year in Review, Part 2
In this episode of Wavelengths, the Amphenol Broadband Solutions podcast, host Daniel Litwin continues his conversation with Alex Rozek, Founder and CEO of Mac Mountain, to examine how technology shifts, capital discipline, and changing consumer expectations reshaped broadband in 2025, and what those changes lock in for the future.
As the broadband industry closes out 2025, momentum has clearly shifted. Fiber and fixed wireless access accelerated subscriber growth, traditional cable continued to lose ground, and satellite connectivity matured into a meaningful, if supplemental,piece of the ecosystem. At the same time, midstream changes to BEAD funding rules, rising data consumption, and the rapid adoption of AI-driven applications have pushed operators to rethink how networks are financed, built, and operated.
Rozek brings a pragmatic, builder-focused perspective to the conversation, grounded in unit economics and long-term infrastructure thinking. In Part 2 of this year-in-review discussion, the focus turns to technology tradeoffs, capital stack strategy, and the question of what 2025 permanently changed about broadband deployment in the United States.
Key Discussion Highlights:
• BEAD Funding Reality Check: Rozek explains why Mac Mountain ultimately chose not to pursue BEAD opportunities in multiple states, citing complexity, compliance costs, and long timelines that often undermine the apparent appeal of grant funding. He contrasts BEAD with alternative financing paths, such as tax-advantaged revenue bonds and private capital, that can accelerate deployment and improve certainty.
• Unit Economics as the North Star: Rather than leading with subsidies, Rozek emphasizes starting with unit economics all-in cost per subscriber, expected ARPU, and long-term cash flow, to determine whether a project makes sense. He outlines a benchmark model where disciplined costs and scalable operations drive attractive returns on invested capital over time.
• Capital Stack Evolution: The conversation details how healthy broadband capital stacks evolve as networks scale, moving from private equity and term loans to warehouse facilities and, eventually, asset-backed securitizations. Rozek notes that while capital availability remains strong in 2025, discipline and sequencing matter more than ever.
• Fiber vs. Fixed Wireless vs. Satellite: Rozek breaks down the physical and economic realities that differentiate connectivity technologies. Fiber’s superior bandwidth, durability, and long-term cost profile position it as the dominant solution for most homes, while fixed wireless and low-Earth-orbit satellites like Starlink play important supplemental roles in hard-to-serve or low-density areas.
• Why Cable Is Struggling: Rising upload demand, AI-driven workloads, cloud-based content creation, and multi-terabyte monthly usage are straining legacy cable architectures. Even with DOCSIS 4.0 upgrades, Rozek argues coax faces structural limits compared to fiber’s scalability.
• AI and the Bandwidth Inflection Point: From video conferencing to generative AI tools, Rozek highlights how rapidly growing upstream and downstream data needs are redefining what “adequate” connectivity means, reinforcing fiber’s role as essential infrastructure rather than a premium upgrade.
• What 2025 Locked In: Reflecting on the year, Rozek suggests 2025 may mark the moment when the question shifted from “Why do we need this?” to “How do we get it?” For consumers, developers, municipalities, and policymakers alike, high-quality broadband is increasingly viewed as foundational, on par with electrification or transportation infrastructure.
This episode builds on the financing and service-model themes from Part 1, adding a deeper examination of technology tradeoffs and long-term infrastructure strategy. Together, the two-part series captures a broadband industry in transition, moving from experimentation and debate toward clearer standards, expectations, and execution paths.
