    It sounds like you’re thinking of LoRa, another 900MHz radio protocol.

    LoRa has similar bandwidth to Zigbee (125kbps), and as you say is designed for low-power devices running on battery. I have PIR motion sensors at home which have used only around a third of their battery after 2 years.

    Security cameras seems to be a large target market for HaLow though, where you need a couple of megabits at a few hundred metres.

      Serious question, why not use current wifi for that kind of distance?

      I know, it’s probably not really easy to make the comparison at this point - power usage is definitely part of that equation. Though the lower bandwidth of this doesn’t seem quite enough for video?

      Edit: I misread the bandwidth as 347kbit, not Mbit. So yea, this looks very promising for video, especially given the limitations of Wifi, plus using less power.
