POCKET SIREN FORUM 2026

Building the Future of Public Warning with 5G Broadcast

22 October 2026 | Tallinn, Estonia

Pocket Siren Forum 2026 brought together experts and project partners from Estonia and across Europe to share the results of the Pocket Siren pilot project and explore the potential of 5G Broadcast as an additional channel for public warning.

Pocket Siren Forum 2026 – Highlights

Held on 22 October 2026 at Tallinn Botanic Garden, the forum marked an important milestone in the Pocket Siren pilot project. Project partners, public authorities, technology experts and stakeholders came together to discuss testing 5G Broadcast for public warning in Estonia.

The pilot investigated a broadcast-based approach that could provide an additional communication channel independent of conventional mobile network capacity. Its purpose is to complement existing warning solutions and strengthen their resilience and reach.

Pocket Siren remains a pilot and research initiative, not a replacement for existing warning channels or an operational nationwide public warning service.

About Pocket Siren

Public warning needs communication channels that remain available under pressure. Pocket Siren (Taskusireen) explores how 5G Broadcast could provide an additional route for distributing alerts, including when conventional mobile networks are congested or disrupted.

The pilot brings together Estonian public-sector stakeholders, research institutions and international technology partners. Levira, TalTech, Tredess and Nakolos carry out technological development and testing.

The project is commissioned by the Strategy Unit of the Government Office and funded under the European Union cohesion policy 2021–2027 measure “Increasing the innovation capacity of the public sector”.

The project is investigating how broadcast delivery could complement existing warning channels. It is a pilot and research initiative, not a fully operational nationwide public warning service.
