NB-IoT is a mobile radio technology specially developed for devices that need to transmit small amounts of data in an energy-efficient and reliable manner.
For operators, this means that a mobile door guard can send status and alarm messages directly to a platform. This allows emergency exits and escape routes to be monitored more effectively, even across multiple locations.
The big advantage lies in everyday use. Instead of relying solely on local signals, those responsible receive information centrally and faster. This saves time and increases transparency.
