For decades, C-band satellite has been one of the foundations of global broadcast contribution and distribution.
Its combination of wide coverage, reliability and resilience against rain fade made it the preferred choice for live sports, news gathering and linear television distribution around the world.
However, the long term future of C-band capacity is increasingly coming under pressure.
In the United States, the FCC is currently preparing a new Upper C-band auction process which could see between 100 MHz and 180 MHz of additional spectrum repurposed for wireless and future 5G/6G services. Industry groups including the National Association of Broadcasters (NAB) have warned that further reductions in available C-band spectrum could place additional operational and commercial pressure on broadcasters and satellite operators already impacted by previous spectrum repacking and compression requirements.
The concern is not simply a U.S. issue.
Many broadcasters, satellite operators and service providers globally are now watching closely because C-band spectrum pressure is part of a broader international trend. As demand for mobile wireless spectrum continues to increase, broadcasters are beginning to question how future contribution and distribution networks will evolve over the next decade.
Outside the United States, pressure on C-band spectrum is also becoming a growing concern across Asia, Africa and other regions heavily dependent on satellite distribution. In a joint industry paper published by the Global Satellite Coalition and supported by operators including AsiaSat, the satellite industry warned that portions of the C-band spectrum are increasingly being considered for future 5G and IMT services, despite the band remaining critical for broadcasting, public services and high-availability communications across many tropical and developing regions. The paper also noted that C-band continues to play a particularly important role in areas where heavy rainfall and limited terrestrial infrastructure make higher frequency satellite bands or fibre based alternatives less reliable.
Unlike previous transitions, the industry may not have a simple “like for like” replacement available this time. A recent white paper released by The Hive Group ahead of NAB Show 2026 concluded that there are “no clear cut” replacements for C-band distribution and that future broadcast infrastructures are likely to involve a combination of technologies rather than a direct one for one replacement.
This is already beginning to change how some broadcasters think about infrastructure design.
Instead of relying entirely on fixed satellite capacity, many organisations are moving towards more flexible distribution models where contribution and delivery paths can dynamically shift between fibre, cloud, satellite and IP transport depending on availability, geography and operational requirements.
At the same time, the rise of cloud production, remote production, pop-up sports events and multi-platform distribution is increasing the operational complexity of live media workflows.
As broadcasters begin combining satellite, terrestrial IP delivery, fibre and cloud based infrastructure within the same operational environment, the complexity of managing contribution and distribution workflows also increases significantly. Broadcasters may need to dynamically route, monitor and scale live video services across multiple transport paths and geographic regions while maintaining the reliability traditionally associated with fixed satellite distribution.
This is one of the areas where software defined and distributed media gateway platforms such as GlobalM are beginning to play a larger role by providing orchestration and control layers capable of managing hybrid contribution and distribution infrastructures across multiple transport technologies and cloud providers.
Platforms such as GlobalM’s GMX Distributed Video Gateway are designed around this type of hybrid infrastructure model, allowing broadcasters to orchestrate contribution and distribution across multiple transport technologies including fibre, cloud, bonded cellular, LEO satellite and open IP protocols such as SRT and RIST.
For many organisations, the future may no longer revolve around a single contribution or distribution technology, but rather the ability to combine satellite, fibre, cloud and IP based delivery within the same operational environment while maintaining operational flexibility and resiliency.
As this transition continues, platforms capable of managing increasingly hybrid contribution and distribution infrastructures are expected to play a growing role in the evolution of broadcast networks.
