The 5G Broadcast technology, whose standardization was completed in December 2025 (news “5G Broadcast: Rai Research Centre drives the standard development in 3GPP Release 19“),  will enable the delivery of live TV programmes to next-generation mobile phones without consuming mobile data nor overloading 5G mobile networks.

The system is based on the broadcast transmission in the UHF band (470–694 MHz), adopting principles similar to those of digital terrestrial television and leveraging the resilient infrastructure of TV distribution network towers.

This approach ensures high-quality reception even in particularly challenging scenarios, such as live coverage of of major sporting events.

The Rai Research Center, in collaboration with the EBU, played a key role in integrating 5G Broadcast into 3GPP standards, actively participating in the working groups. Key features of Release 19, approved between 2024 and 2025, include Time-Frequency Interleaving, which improves receiver performance, and the definition of subbands in the UHF band (470-698 MHz), which accelerates the global industrial adoption of the technology. The completion of the Work Items in December 2025 confirms the Rai Research Center’s role as a leading player in the innovation of future broadcasting systems.

As part of World Radio Day 2026 – dedicated to “Radio and Artificial Intelligence” – COPEAM has established a new collaboration with UNESCO to develop a pilot action focusing on a concrete and innovative application of artificial intelligence to the radio. The pilot project is implemented in collaboration with the Ca’ Foscari University/Venice and Rai’s Research and Technological Innovation Centre (CRITS)

CPTO, 9-11 dicembre 2025

RAI CRITS organised a workshop dedicated to virtual production with volumetric LED wall technology, offering participants a high-level training experience.

These LED walls are defined as ‘volumetric’ because they are often configured with a floor and ceiling, creating an immersive environment that wraps actors or presenters in a virtual space in real time. This approach overcomes the limitations of previous technology, the green screen, which forces performers to work in a completely green environment, devoid of visual references, often generating a sense of alienation.

The practical initiative was carried out in collaboration with the EBU’s LED Virtual Production group and with the support of Sony, involving key figures from the RAI company’s management, including TV Production and Technologies.

LE FIL ROUGE –Vietato non toccare

Among of Rai’s initiatives on accessibility and inclusion, Rai Valle d’Aosta has produced the episode “Vietato non toccare” of the series Le Fil Rouge, a program by Paola Corti and Ilaria Macrì. The episode follows a group of blind and visually impaired visitors of the Unione Italiana Ciechi e degli Ipovedenti-Valle d’Aosta in the Rai Museum of Radio and Television.
