My understanding is that the difference between 5G density/localization and that of previous technologies is quite substantial, especially in urban areas.

"The extension of spectrum range has an impact on the network architecture. mmwave cells will employ shorter ranges of around 100-to-200 meters which will require extreme densification to provide high coverage. 3G networks reached densities of fourto- five base stations per km², 4G networks eight-to-ten per km², while 5G networks could reach densities of 40-to-50 per km²."

I'm wondering how much worst it is since we already can track people pretty well with cellular data now. Sorry if I didn't make that clear, seems like they can already do all those things. How much worst can it be?

Its the difference between knowing which neighborhood you're in and which street or mabye even which house you're in.

But you can already tell what house you're in with triangulation, and even the room.

Source on this? Maybe you can do it if it's combined with wifi/bluetooth signals, but I doubt you can do it with cell towers alone.

Yes you can. I used a jailbreak app on ios6 and I used llama on Android for this.

I got my own room in my house with it, back in the 3G/4G days. I'm not sure what modern software and hardware can do it now, but I'm pretty sure it's even more accurate even without 5G.

>A number of factors can impact location data accuracy, including its source, which can include GPS signals, Wi-Fi and cell tower triangulation.

Seems like the figures they're giving is with wifi/gps signals, not just cell tower alone.

I am sure they were able to do it without it, but others can interfer. Triangulation was already a thing in the courts. https://www.eff.org/deeplinks/2018/06/victory-supreme-court-... It's in Carpenter vs US, for deducting he robbed a store from just the cell phone signals.
