We conducted an overview of the selected technologies (SigFox, LoRa, Wi-Fi HaLow, Zigbee, BLE 5) based on their documentation and described scenarios in which they would be most useful. In addition, we used a multimeter to measure the current consumption of the Dragino LoRa shield v1.3 (LoRa RFM95W) in different operating modes with a focus on sleep mode and concluded that the consumption is orders of magnitude greater than what is suggested in the documentation.
