For IoT applications, low-power wide area networking (LPWAN) can be used as the radio communication. Unlike LPWAN, however, conventional cellular standards must connect a smaller number of end users and ensure a high data transmission rate to support multimedia services, for example. LPWAN, on the other hand, is designed to be as energy efficient as possible, with each sensor transmitting its data to all gateways within its range. This means that small amounts of data can be transmitted with low transmission power over significantly longer ranges, and battery operation is also possible for years. In addition, license-free frequency bands can be used, enabling rapid commissioning.
The gateways then send the data to their network management system, which then forwards the data to the appropriate applications. The data transmission can be protected with modern AES encryption. To prevent the operator of the network system from reading the data, it is additionally encrypted with the application key.
For these networks, LoRa is suitable as a physical layer for radio communication over long distances. It is based on chirp spread spectrum (CSS) modulation, which is more robust than FSK (frequency shift keying). This means that data can be transmitted over much longer distances with low transmission power.
