Which of the following is an LPWAN technology?

LPWAN is about connecting many sensors over long distances with very low power, so devices can run on small batteries for years while sending small data packets. LoRa fits this model by using low-power radio in sub-GHz bands and a gateway-centric, star-like network that can cover wide areas; its modulation and network design prioritize long reach and minimal energy use, which is why it’s a classic LPWAN example. WiFi, by contrast, is built for higher data rates over short distances and consumes more power, so it isn’t LPWAN. LTE is a cellular technology aimed at mobile broadband, and while there are LPWAN variants, the traditional LTE setup isn’t classified as LPWAN in IoT contexts. Sigfox is another LPWAN option, but LoRa is the example highlighted here.
