That's pretty good given (as far as I know) the main use case for HaLow is for low bandwidth, very low power use cases, like for IoT devices and other things you'd use Zigbee or Z-wave for today, including devices that run for years off a single button cell battery

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.

I've never heard of LoRa. The marketing and whitepapers for HaLow specifically mention the things I did, for example https://www.wi-fi.org/discover-wi-fi/wi-fi-certified-halow
