LPWAN technologies, such as Sigfox and LoRaWAN, are known for what characteristic?

LPWAN (Low Power Wide Area Network) technologies like Sigfox and LoRaWAN are designed specifically for low-bandwidth communications over long distances while maintaining very low power consumption. The characteristic that defines these technologies is their lower data rates compared to cellular networks. LPWANs typically transmit small amounts of data infrequently, making them ideal for applications like remote sensor monitoring where small packets of data are sent periodically.

Cellular networks, on the other hand, support higher data rates suited for streaming, video calls, and other high-bandwidth applications. Thus, the lower data rates of LPWAN technologies are a defining feature, allowing for extensive coverage and long battery life, which is crucial for Internet of Things (IoT) devices deployed in various environments.

The other characteristics mentioned do not align with the core attributes of LPWAN technologies. For instance, unlimited range is unrealistic; LPWANs offer extended range but are still subject to limitations such as signal interference and location of gateways. High power consumption contradicts the fundamental design of LPWANs, which prioritize energy efficiency for devices that often run on batteries for extended periods.
