Characterization of LoRa Devices
The term “LoRa” (Long Range) refers to a physical layer (PHY) with a modulation type developed by Cycleo. Here, transmission takes place in the license-free ISM bands. Owing to the low power consumption, LoRa is ideal for data transmission in IoT. Before devices can be used in a LoRaWANTM network, they must among other things meet country-specific wireless communications regulations. This application note shows developers and manufacturers of devices with LoRa wireless technology how transmitter measurements are conducted in line with FCC Part 15.247, describes how important receiver characteristics can be verified by metrological means, and how current consumption of LoRa wireless modules can be measured reliably.
