> The Wi-Fi 7 Sensing draft standard is proposing to make this available to everyone. As your sentence before this says, it already is available to everyone. The only thing wifi 7 opens up is someone with less technical know-how being able to flash openwrt and install some program that extracts and/or visualizes the sensing data, but $20 ESP32's isn't much of a cost to someone looking to use radio wave sensing malici…
> To be clear, this can be done today with $20 ESP32 WiFi devices + custom firmware, i.e. any motivated attacker can already see through the walls of homes and businesses. The Wi-Fi 7 Sensing draft standard is proposing to make this available to everyone. It's like you could make a magic flashlight that sees though walls, vs. flipping a switch that turns every wall to glass. It's not a perfect metaphor, sure, but the…
Exactly. After 10 years of research and hundreds of published papers, there is a huge gap to be bridged with consumers, regulators and lawyers, before dramatically changing the definition of "fitness for purpose" in wireless networking, https://dhalperi.github.io/linux-80211n-csitool/#external

Not trying to be provocative, but how is this any worse than existing cameras or motion sensors?

I cant see through walls with a lightbulb. I can with wifi. This standard makes my wifi router into an internet connected, closed source blob, light bulb and camera that is impossible to obscure (without killing my internet connection). Sure, I can wire my whole house for ethernet. And, while I’m behind the drywall, I might as well rip off all the drywall put a layer of Al. Here’s a business idea - drywall with alumi…
To put a slightly finer point on it, I can't see through your walls with my lightbulb, but I probably can see through your walls with my router. Your creepy neighbor in the apartment next door is getting a new toy.

Your next door neighbor’s wifi will know your every movement, and can probably image it too. End of privacy within closed doors.

2.4GHz, 5GHz, and 6GHz have decent wall penetration, but 60GHz doesn't. It can bounce off walls to get around corners, so it doesn't necessarily need line of sight.

I think we're all being a little maximalist here? I think it's fair to say this article's focus is on the tech, so it doesn't discuss the cool stuff (incredible VR experience, sci-fi like gesture apps) or the bad stuff (Google knows when you scratch your ass). I think it's reasonable to read an article that doesn't mention any usage restrictions, look at the track record of tech, and worry about the privacy implicati…
It's starting to feel like the #1 go-forward privacy law needs to be a mandatory opt-in choice requirement, with a viable refuse option. It can be asked once at the device level, but regulated information needs to be specified at the highest level (e.g. "location information about an individual"), and then the concrete technical implementation left unspecified. "Does it, or does it not?" is more important than "How?"…

This is hyperbole. 60GHz cannot penetrate walls and closed doors. 2.4GHz and 5GHz lack the resolution to image you, especially if your adversary only has control of one AP. There are already tons of side channel attacks with existing WiFi and Bluetooth that reveal when someone is in the area. Your neighbour could already be tracking your devices, for all you know.

I don't need more than a few hundred megabits on the go, thank you very much. If I want to go faster, and Ethernet cable is always a faster solution with less moving parts.
When it comes to consumer gear, modern WiFi equipment is often faster than even Ethernet. I agree with your overall point, though.
