Which of the following is an LPWAN technology?

LPWAN is about long-range, low-power connectivity for devices that send small amounts of data infrequently, so batteries last for years and devices can be widely dispersed. LoRa is built for this model: it provides long-range communication with very low power consumption and low data rates, typically using a star-of-stars network where end devices talk to gateways that forward data to a central server. That combination—great range with minimal power use—is what defines LPWAN. WiFi is designed for high-speed local access with relatively short range and higher power use, so it isn’t LPWAN. LTE targets mobile broadband with higher data rates and power needs, not the ultra-low-power, wide-area pattern LPWAN aims for. 6LoWPAN is IPv6 over low-power personal area networks and is geared toward short-range, local networks rather than wide-area coverage. So, LoRa fits the LPWAN category.
