Abstract A large number of different low-power wireless network technologies exist, including IEEE 802.15.4, Bluetooth Low Energy, multiple protocol standards of WiFi (IEEE 802.11), Near Field Communication (NFC), and LoRa. Given this number of competing technologies, the selection of the best one for a new project is not trivial. This paper aims to help Internet of Things (IoT) practitioners in this task. To this end, we illuminate the underlying technical differences between these state-of-the-art wireless solutions through their assessment and brief analysis. We quantify and compare their latency, throughput and overhead, as well as overview their main characteristics such as frequency bands, bandwidth, medium access methods, and packet sizes.
