It's low-energy like Bluetooth/Zwave/Zigbee, long range like any other 900Mhz Band protocol (LoRA does 10km or so in normal conditions, can go even further), but for when you need higher datarates. According to the Wikipedia chart it can max out at ~300 Mbps depending on modulation, though I don't know enough to speak to range/bandwidth tradeoffs, though I imagine there are.

Honestly seems pretty interesting. I had a lot of fun setting up a 4G carrier for my home so I can get decent speeds out on my back porch (5GHz can't cut through my ancient balloon frame walls/door, and 2.4GHz is a congested soup around me, useless), I wonder if I can wrangle some hardware together and start experimenting with this. Could be nice to get some remote SDR workloads off of 2.4GHz while still getting WPA3 encryption.
