When Every Second Counts: 5G Broadcast for Public Safety

August 1, 2025

Even in an age of constant connectivity, emergency alerts remain one of the most vital tools for public safety. In moments of crisis, delivering clear and timely information can save lives—and governments worldwide are working to ensure their citizens are reached without delay. The upcoming UK nationwide emergency alert test serves as a timely reminder of just how important these systems are.

Taking a step forward, Estonia recently conducted a large-scale national test using 5G Broadcast for emergency alert delivery. The exercise demonstrated how broadcast technology can transmit real-time instructions directly to smartphones without relying on the internet or cellular networks. These trials highlight the unique strength of 5G Broadcast: resilient, one-to-many delivery that remains operational even during network congestion or outages.

This is where 5G Broadcast makes the difference. Its ability to send synchronized alerts to unlimited devices without consuming cellular bandwidth positions it as a critical layer for modern public safety. From text and maps to audio and video instructions, 5G Broadcast ensures that every citizen can receive the right message at the right time—even under the most challenging conditions.

By integrating 5G Broadcast with traditional alert systems, governments and broadcasters can create a multi-layered, fail-safe alerting infrastructure. Beyond basic text messages, it enables the delivery of rich, actionable information to unlimited devices simultaneously—making sure that life-saving instructions always reach those who need them most.

As deployment approaches, its role in public safety and emergency preparedness is increasingly clear: 5G Broadcast is built for the moments that matter most.

Terrestrial Broadcasting for Europe’s Digital Future-BNE Long Term Vision

With its trusted free-to-air content, terrestrial television and radio are essential to European life. As the EU enters a new mandate, urgent action is needed to support innovation and to secure long-term access to the UHF spectrum (470–694 MHz). Terrestrial broadcasting ensures universal access to viewers, reinforces sovereign infrastructure, and sustains Europe’s vibrant content sector. It is essential to media pluralism, democracy, and cultural diversity.

Media Broadcast will stick to 5G Broadcast

The most important player in Germany is expected to be the technology company Media Broadcast. As opposed to teltarif, the people of Cologne have now confirmed their intention to not retire from the technology, unlike ARD. "Media Broadcast has intensively supported the rollout of 5G Broadcast in Germany and Europe in the past and will continue to do everything together with their international partners to implement this forward-looking technology," the company said.

Future of Local TV Hinges on Mobile Revolution and a Collaborative Path

In the US a pivotal debate is underway at the Federal Communications Commission (FCC), with low-power television (LPTV) stations asserting that the future of local broadcasting depends on embracing 5G Broadcast as a direct path to the mobile-first world. This position stands in contrast to the National Association of Broadcasters' (NAB) recently intensified push urging the FCC to implement a mandatory nationwide transition to ATSC 3.0 for full-power stations by 2030 and require ATSC 3.0 tuners in all new TV sets.

ARD halt 5G Broadcast development, top EU broadcasters on track

The decision by ARD, the German broadcasters’ working group, to halt 5G Broadcast (5G-B) development in the country after years of testing has not dented enthusiasm among some other leading continental European broadcasters, which remain committed to commercial deployment – around 2027.

ARD decides against 5G Broadcast introduction

German public broadcaster ARD has decided not to adopt the new 5G Broadcast standard for the time being, although it has not ruled out introducing the technology at a later date. “At present, ARD has decided against investing in the new 5G Broadcast transmission technology but still considers a future rollout possible,” an ARD spokesperson confirmed.
