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. It also describes how important receiver characteristics can be verified by metrological means. In this context, battery life in particular plays a key role in IoT applications. A further chapter describes how current consumption of LoRa wireless modules can be measured reliably.
