    Having this on a Wyze cam would be really interesting. 4mbps would be enough for 720p video…and at almost 10 miles??

    I am interested in knowing what’s the bandwidth to transmission power ratio of the device. If it’s low enough, it would be revolutionary for IoT devices.

      https://en.wikipedia.org/wiki/IEEE_802.11ah

      347 Mbit/s maximum. (But don’t expect that at 9.9 miles…)

      The "WiFi HaLow"name itself indicates lower power usage than traditional Wifi, largely because it uses the 900MHz band instead of the 2.4/5/6GHz bands.

      Likewise, it isn’t compatible with existing WiFi client devices that don’t operate at those bands.

      Looks like around 4Mbps link speed, so great for sensors and remote monitoring/controls and that kind of thing.

      Sort of in between LoRa and normal Wifi.

        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.
