As the FCC plans to auction an additional 100 MHz of Upper C-band spectrum by July 2027, broadcasters and cable networks face critical decisions regarding video distribution. Harmonic is offering solutions like Ku-band with RIST, managed IP, and hybrid Sat/IP to help clients transition from C-band and ensure continued content delivery. The article outlines the challenges and various alternatives for distribution in a post-Upper C-band environment.
The reclamation of Upper C-band frequencies represents a major infrastructure shift for the 120 million U.S. households that rely on terrestrial and cable primary distribution. For broadscale broadcast and cable networks, the forced move away from a fixed-cost 'one-to-many' satellite model toward tiered IP and CDN solutions introduces new variables in latency and last-mile management. This transition accelerates the industry's pivot toward software-defined networking at the edge. Strategic success now depends on whether hybrid architectures can maintain deterministic switching and synchronized outputs across thousands of affiliate endpoints. Watch the FCC’s final clearinghouse rulings for potential cost-reimbursement incentives aimed at accelerating the transition ahead of the 2027 deadline.
The Federal Communications Commission (FCC) officially initiated the Upper C-band clearing process in late 2025, voting 3-0 in November to advance a Notice of Proposed Rulemaking (NPRM). This move follows the passage of the One Big Beautiful Bill Act (OBBB Act) in July 2025, which restored the FCC’s auction authority and set a timeline to repurpose at least 100 MHz—and up to 180 MHz—of the 3.98-4.2 GHz range for 5G and 6G wireless services by July 2027. Per TV Technology (November 2025), the FCC intends to model the transition on the prior Lower C-band clearing, which successfully raised over $81 billion for the U.S. Treasury and provided incentive payments to satellite operators SES and Intelsat.
Simultaneous with regulatory moves, managed IP providers are reporting a significant surge in demand as broadcasters seek alternatives to shrinking satellite capacity. In August 2025, LTN announced that its distribution to North American pay TV households grew by 200% year-over-year, reaching 98% coverage with a target for full saturation by 2026. This growth is supported by partnerships with software-defined video platforms like Zixi, which now facilitates live video exchange for over 1,400 media companies across 120 countries, according to Zixi's 2024 annual performance data.
Harmonic signaled its intent to lead the technical migration at the April 2026 NAB Show, where it demonstrated enhancements to its XOS Advanced Media Processor designed specifically for the post-satellite era. Per Digital Media World (March 2026), these updates include localized playout and AI-powered automated closed captioning, allowing broadcasters to consolidate traditional IRD functions and playout workflows into a single appliance. These developments occur as the industry increasingly prioritizes protocols like SRT and RIST to overcome the inherent weather-related signal degradation and solar outages associated with the Ku-band satellites currently being cross-strapped to replace legacy C-band downlinks.
