Denmark Tests Blackout-Ready Emergency Network in Aarhus

Denmark is testing an off-grid radio network to keep emergency communications open during major power outages. The pilot project in Aarhus tests Meshcore to contact local schools when mobile networks fail.

According to a report by Militarnyi published on news.az, Meshcore uses small radio devices powered by batteries and solar panels. Users connect these devices to their smartphones using Bluetooth. They can then send messages through a mobile app even if cell towers stop working. Standalone repeaters help extend the network coverage across the area.

Kristian Risager Larsen leads the IT team at the Municipality of Aarhus ITK department. He explained that the test will check if the city can reach schools during crises. The system could provide updates on power outage length and drinking water locations.

Private individuals originally created and expanded the Meshcore system. Dennis Borup Jakobsen heads the ITK Tech Lab unit in Aarhus. He runs the Meshview.dk website in his spare time. He estimates Denmark currently has about 400 Meshcore users.
