The room next to where you installed it at home will still have problems getting more than 2 lines of WiFi.
Just tear down this wall
Not a bad thing honestly, whats nice about high frequencies is lower penetration. More access points, lower power, overall better signal and less interference. Line-of-sight microwave for covering distance.
Fun stuff
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.

You might want to look at LoRa
Having this on a Wyze cam would be really interesting. 4mbps would be enough for 720p video…and at almost 10 miles??
But at what speed?

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
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.
