<p>As part of a large-scale disaster management exercise conducted in the municipality of Am Mellensee (Brandenburg, Germany), TJK-Solutions deployed a Meshtastic-based emergency communication network to test how decentralized systems can ensure reliable information flow under crisis conditions. To maintain full visibility of this critical infrastructure, the company implemented ThingsBoard Professional Edition (PE) on local servers — enabling continuous real-time monitoring of nodes, routers, and connections essential for emergency coordination and disaster response.</p>
