I've recently vibe-coded "where-am-i", a small CLI that returns your approximate location using the technology described here. https://github.com/denysvitali/where-am-i Tbh, I think this geolocation method is amazing, and I'm grateful it exists, because GPS indoor really sucks.
Honest question - what's your use case for needing GPS indoors? I generally know where I am when I'm indoors :)

People need to learn manners, nobody should be using video calling without headphones. It's insane whenever someone joins and we hear all their background, feedback of whoever is speaking, etc as if nobody has ever told them to mute or stop using speaker in their life.
> People need to learn manners, nobody should be using video calling without headphones. OK? it still sucks even with headphones. Imagine the following scenario: You are in a meeting using your headphones as you suggest. A coworker a few seats away from you are in the same meeting using their own headsphones. When they talk you hear their real voice reach your ears first (this happens with even the best noise canceli…
Now the question: can you spoof your location? Say you are an admin on your system (for instance you run a Linux distro), can you make your OS return the same list of SSID/BSSIDs as your friend who is in the classroom (or as you recorded the day before) to pretend you are there? Would be a fun experiment, and a nice follow-up post :-).

This is a great answer. But I would add that while a technical solution is welcomed, an organizational one could help too: why are multiple people in the same meeting joining from nearby desks instead of a conference room?
I've had companies send us laptops for VPN access that had LTE modems and GPS specifically for location verification before granting access to the VPN.
Imagine having your services so poorly secured or authenticated that you need to protect Layer 3 access this tightly.

So unless I know the voice of everyone in the conference room, I have no idea who's speaking at any given point unless they're also gesticulating wildly.
> Small digression: did you know that, until May 2000, GPS satellites (which are owned and operated by the United States Space Force) provided the general public a signal with intentional error built into it? What the hell? Why?
Maybe it’s because I studied in Austria where universities generally provide very little handholding to students but I don’t understand the point of compulsory attendance in university lectures. If students think they can pass exams without attending the lectures then they should be able to do that. I certainly did that once or twice when I realized I needed some more credits before the end of the term. It’s a differ…
As for laboratory exercises in the physics department, they were in theory compulsory but still no one checked. The final year included a long experimental project that had to be documented and conclusions defended in a viva. Again no one formally checked that we actually did it but as we were grouped into small teams for this anyone who didn't pull their weight would have been reported by their fellow students and would not have had access to the experimental results which would have made it difficult to write it up and defend.

Finding students with integrity is hard now, because the culture is already full of poo. But one starting point is to communicate that you expect and require integrity, explain what that means, and then expect it. Trying to make metrics or tests or whatever to detect, rate, rank, etc. it just turns it into a game, like the same load of poo. Though here is one thing you can do. Explain that you expect integrity, and t…
> Explain that you expect integrity, and then watch the students raise their hands and ask how they will be tested on this. You say it's expected. Back and forth a few times, until eventually some of them start crying, and then their heads explode, because they can't figure out how to game that. This assumes that the students are untrustworthy and the faculty/institution are ultimately trusted. In a world in which th…
True. This proposal requires expecting and requiring the faculty to have integrity.
And you really need the college/university as a whole to commit to this, not just isolated professors, partly so that there can be no confusion by students.
(Some battle-scarred faculty and grad students could tell speak of entire departments that need to be shut down completely, because the administration and faculty are too far gone. I think you could never do this with one of those departments. You'd only get posturing, and the same arrogant and underhanded behaviors as before, and students would briefly be a little confused, but quickly realize that the old sketchy game-playing is still fully on.)

Even if the browser was super locked down you could trivially spoof a few SSIDs broadcast from the desired area in theory..
The SSID (name, like the article mentions) is different than the bSSID (mac address of the access point), so I don't think it would be that easy to spoof.
The BSSID is unique per SSID, per AP. The BSSID is usually derived (usually by incrementing the last octet) from the AP MAC address, however.
So an AP MAC might be 77:99:44:EE:C4:11.
It has a wireless network called "Bob's SSID". It will have a BSSID of something like 77:99:44:EE:C4:12.
Then, the AP may be broadcasting another called "Mary's SSID", and it will have a BSSID of something like 77:99:44:EE:C4:13.
Edit: More not-well-written info on BSSIDs: https://en.wikipedia.org/wiki/Service_set_(802.11_network)
Looks like the BSSID is derived from the AP serial number by some vendors. Never seen that myself.
