Broadcast Infrastructure

5G Broadcast infrastructure

For public warning, mobile distribution and resilient nationwide delivery.

Levira develops and tests 5G Broadcast solutions in Estonia, helping public sector organisations, broadcasters and partners evaluate future deployment models.
This approach is currently validated through the Pocket Siren project — a real-world public warning initiative using broadcast-based delivery.

5G Broadcast

What is 5G Broadcast and how it works

Traditional mobile delivery scales one user at a time. 5G Broadcast introduces a one-to-many model — allowing the same content, alert or stream to reach large audiences simultaneously without depending on cellular capacity.In Estonia, this approach is being validated through the Pocket Siren project — a real-world pilot focused on public warning and resilient mobile communication.

It creates a new delivery layer between broadcast and telecom — combining nationwide coverage, spectrum efficiency and mobile reach.

One-to-many delivery

Transmit the same content or alert to large audiences simultaneously.

Resilient communication layer

Operate independently of congested mobile networks during peak load or crisis scenarios.

Broadcast-grade coverage

Use high-power broadcast infrastructure designed for wide-area transmission.
Capabilities

Core 5G Broadcast capabilities for nationwide delivery

5G Broadcast adds a scalable delivery layer for public warning, mobile distribution and future hybrid media services — built on broadcast infrastructure and tested through real-world use cases in Estonia. These capabilities are currently being validated through the Pocket Siren project in Estonia.

5G Broadcast for public warning systems and emergency communication

5G Broadcast adds a new nationwide layer for public warning systems — complementing existing channels such as SMS alerts, sirens and broadcast media.

Levira is actively involved in the Pocket Siren initiative in Estonia, where 5G Broadcast is being tested as part of a multi-layered national alerting concept.

5G Broadcast for broadcasters and mobile content distribution

5G Broadcast opens new possibilities for direct-to-mobile distribution — extending traditional broadcast reach into mobile environments.

It enables scalable delivery of live channels, events and media services without the limitations of one-to-one streaming.

FAQ

Frequently asked questions about 5G Broadcast

Key questions about testing, deployment and use cases.
No. 5G Broadcast is not yet commercially deployed in Estonia. Pocket Siren is a live pilot project designed to test whether 5G Broadcast can become a reliable part of Estonia’s national public warning system. The project is currently focused on testing, validation and future deployment planning, not commercial rollout. 
 Levira is the technology, infrastructure and pilot implementation partner in the Pocket Siren project. The project itself is led by Estonia’s public-sector emergency warning stakeholders, while Levira, together with TalTech and technology partners Tredess and Nakolos, carries out the technological development, network build-out, piloting and testing. 
 Not yet. In the current pilot phase, 5G Broadcast should be described as working on selected supported devices rather than all smartphones. The project is still validating real-world device behaviour, alert activation and compatibility before any broader deployment claims are made. 
 5G Broadcast is relevant for governments, public warning authorities, broadcasters and infrastructure operators that need resilient one-to-many mobile distribution. In Estonia’s case, the main use case is public warning, but the same technical approach is also relevant for media delivery and other large-scale broadcast use cases. 
 Estonia is relevant because it is one of the first countries testing this type of solution as part of a national public warning architecture. The project combines a real public-safety use case, a multi-layer emergency warning environment and high-power broadcast infrastructure, making Estonia a strong real-world testbed for 5G Broadcast. 
 Yes. Based on its role in the Pocket Siren project and its broadcast infrastructure expertise, Levira can support 5G Broadcast projects outside Estonia with feasibility work, pilot design, infrastructure planning, implementation support and testing.
