2025 scenarios for the UHF band & the role of hybrid networks

Terrestrial broadcasting plays a significant role in TV reception... but the UHF (Ultra High Frequency) band is highly coveted by the mobile industry.

Hybrid networks could provide an answer to spectrum scarcity in the UHF band.

This report presents the most likely scenarios for the UHF band and the role of hybrid networks between now and 2025.
