UHD Spain takes a position on the use of the radio spectrum

With the aim of proposing solutions to improve wireless connectivity in the production of television events, UHD Spain has prepared a document in which it expresses its position regarding the use of the radio spectrum.

5G technology with dedicated spectrum could be useful for recurring services on television sets, sports stadiums or concert halls, among others.

In the past, television cameras were connected by cables to a control center. Today wireless connections are used in the 2400 MHz band, but they also have technical limitations, especially with Ultra High Definition. According to Xavier Redón, vice president of UHD Spain and Product Manager of Cellnex Telecom, “the spectrum assigned for this type of communications is limited, which presents a challenge to transmit in UHD.”

In October 2023, the UHD Spain association carried out a IP-based production proof of concept of a live musical concert. They connected four 4K-HDR cameras to a private 5G network, allowing all four cameras to stream simultaneously and in Ultra High Definition. Redón has commented that this experience meant observing how this spectrum turned out to be highly effective in improving the quality of transmissions.

UHD Spain offers contact with dedicated spectrum for connectivity in audiovisual events. This would allow communication to be integrated into current production flows and use the same communication equipment as in the public 5G network. Furthermore, the association advises that this spectrum be operated by actors with the necessary technical training to ensure its maximum efficiency and quality.

Xavier Redón emphasizes the importance of this measure stating that “at UHD Spain, we believe that it is crucial to consider the needs of the audiovisual sector when temporarily allocating spectrum for wireless contributions in UHD, thus facilitating the production of events in temporary and occasional locations.”

This technology will allow offshore production models, reducing costs and improving efficiency. To all these positive aspects we must add that it helps reduce the carbon footprint and facilitates work in rural and remote areas. For Redón, "the direct benefits for the public will include greater availability of live and Ultra High Definition content. This means an improved and more immersive experience for viewers."
