The Berliner Hauptbahnhof LoRaWAN-Gateway project deploys a Long Range Wide Area Network (LoRaWAN) gateway at Berlin's central railway station, one of Europe's busiest transport hubs. LoRaWAN is a low-power, long-range wireless communication protocol specifically designed for Internet of Things (IoT) applications, enabling sensors and devices to transmit small data packets over distances of several kilometres while consuming minimal energy. By installing a LoRaWAN gateway at the Hauptbahnhof, the project extends Berlin's IoT connectivity infrastructure to cover the central station and surrounding areas, enabling a wide range of smart city applications. Potential use cases include real-time monitoring of passenger flows and crowd density within the station, environmental sensing for air quality and temperature, structural health monitoring of the station building, smart waste bin management, and tracking of logistics and cargo movements. The gateway also supports broader urban IoT applications in the surrounding Europacity development area, including smart parking, building energy monitoring, and public safety systems. The project is part of Berlin's wider strategy to build a city-wide IoT network using LoRaWAN and other low-power wide-area network technologies, creating the connectivity backbone necessary for scalable smart city services. By choosing an open, community-supported protocol like LoRaWAN, the project avoids vendor lock-in and enables interoperability with a vast ecosystem of sensors and devices from multiple manufacturers. The Hauptbahnhof installation serves as a high-visibility demonstration of how existing urban infrastructure — railway stations, bridges, tall buildings — can be leveraged as mounting points for IoT gateways, extending network coverage efficiently and cost-effectively across dense urban environments.
