I'm surprised that there's not a single comment here about 802.11ay which is also 60GHz. Each channel on that standard can do something like 40Gbps, which is nuts. From Wikipedia[0]: > The link-rate per stream is 44 Gbit/s, with four streams this goes up to 176 Gbit/s. Yes, it can't penetrate walls, but is huge for point to point communication. Think VR headset bandwidth, file transfers between devices, wireless back…

So if I don’t want anyone taking a WiFi “photo” of me on the throne I should put up aluminum foil curtains?

Wear a tin foil hat. And take a photo of yourself anyways cause a guy on the throne with a tin foil hat on sounds hilarious

> You can "sense" with a lot more resolution if you use a camera and light bulb. (Visible) Light has a frequency of around 400-790 THz, which explains why it has a inherently better resolution.

Li-Fi can also serve to identify an object’s indoor position more accurately than Wi-Fi or GPS used today (less than 2cm and less than 3 degrees of orientation while it is providing real-time localization (less than 34ms)…

There's potential for visible-light networking but the Li-Fi people in particular are complete garbage. They claim visible light travels faster than radio waves and say Li-Fi is a hundred times faster than wi-fi but their thousand dollar router can only do 100Mb/s. They also rip off the Wi-Fi Alliance logo.

Please dance the Amazon Verification Dance. I cannot fathom any good use for this technology.

Adaptive ventilation and maybe even heating of rooms depending on the number of people present.

You can add a 100 euro CO2 sensor to control your HVAC.

There isn't a use case for this that isn't abusive outside an industrial setting.

I think if ISPs push for these in routers we will see comeback of rewiring houses with ethernet points.

That's disappointing, sounds like they need competition.

The only real practical example is fall detection, what's the real purpose of this?

I've long had an obsession with energy savings and heating, and I think the best way to save energy on heating is by heating people instead of building. With accurate person detection in a room, you could shine low intensity IR at their exact position to keep them warm without wasting energy on heating the rest of the room.

But yeah, I think we can all expect this will be used to monitor behaviour in stores, to spy on people in homes, to rob us and to throw more "relevant" advertising in our faces.

This has nearly zero non-orwellian use-cases inside a home.

Of course there are all sorts of positive applications for the user. It's just their number is dwarfed by the real purpose of these things. We've known they've been coming for a while. Now they here and we'll have to fight it, then lose.

There seems to be a lot of FUD about this. Make no mistake, the malicious and privacy invasive applications are already being used; they just don't follow a IEEE spec and aren't associated with WiFi directly. If a maliciously controlled router wants to track you it already can because your phone, smart watch, and laptop already broadcast themselves. This technology may not seem useful to the purpose of WiFi on it's f…

So there’s FUD about something we should already reasonably have FUD about?

Who is actually asking for this? It can't be for consumers just wanting to use the internet right? I don't get it.

I don't know. Maybe I'm just getting old. It seems this, like a lot of new tech these days, will end up offering little benefit while providing new malicious capabilities.

It's been the same throughout history. Invent a tool...use it to kill.
