What the pilot delivers
The aim of the pilot is not a finished service. It is evidence-based knowledge of whether and how 5G Broadcast should be added to Estonia’s national public warning system, and what it would cost.
Four questions we are answering
Pilot platform
A 5G Broadcast network that delivers CAP-based alerts as well as TV and radio.
Performance in different conditions
Urban and rural, outdoors and in shopping centres, in cars and at sea. Drive tests across Estonia in 2025 and 2026.
Suitability assessment
Is the alert fast, reliable and location-accurate, and do sound, light and vibration work?
Recommendations
Proposals for further development and a possible nationwide rollout.
What the pilot will produce
- Test report with a theoretical overview and an assessment of whether the solution suits a nationwide network.
- Measurement results for public warning over 5G Broadcast: coverage, quality, location accuracy.
- A network model covering Estonia: frequencies, masts, transmitter power and types, and quality requirements.
- Development and operating cost estimate for two scenarios: public warning only, and public warning with media delivery.
- Process description for adding 5G Broadcast to EE-ALARM, plus recommendations for training the public and authorities.
What is worth testing after the pilot
The pilot raised topics that could not be fully verified in the test network. The final report lists them as proposals.
Multilingual alerts
Does the phone automatically show the language version of a CAP message that matches its system language (et, en, ru)?
Updates without a new alarm
A change in the situation (e.g. a storm going from orange to red) reaches the phone without repeated sound and vibration. The new app version is shown at the Pocket Siren Forum on 22 October 2026; it needs systematic testing on different phones.
Verifying the duplicate-alert fix
The cause is known: the alerts’ geographical scope was a single cell. A network-wide (PLMN) scope must be verified before deployment in a drive test between transmitters (3GPP TS 23.041).
The pilot and beyond
| Period | Phase | Content |
|---|---|---|
| H1 2025 | Network build | Transmitters and core, freeing up E41 (MUX7 moved to E35), integration with EE-ALARM |
| 07/2025 – 10/2026 | Technical and user tests | Test days, indoor measurements, drive tests across Estonia, closing event Pocket Siren Forum on 22 Oct 2026 |
| late 2026 – 01/2027 | Analysis and final report | Suitability assessment, network model, cost estimate, recommendations |
| 2030+ | Possible rollout | Depends on government decisions, legislation, the frequency plan and phone manufacturers’ readiness |
