5G significantly increases granularity by a metric shit ton, and if they were continually pinging in the same area, eventually you end up with roughly one zone.

- tiagod 6y agoWho the hell has a 5G device?
- scsilver 6y agoAlot of people buy new Iphones.
- ev1 6y agoYou don't even need iPhones - most of the cheap prepaid brands that you'd see next to a payday loan shop are offering Samsung's lower grade phones or OnePlus 5G phones for free if you set up autopay (it's locked to that carrier). Of course it comes with even more privacy-violating bloatware than ever, but still - 5G is no longer a rarity or expensive.
- gambiting 6y agoIs this....a serious question? All new iPhones are 5G compatible for the start and they sell millions, and loads of other manufacturers have released 5G compatible phones. In fact I'd risk a guess that if you bought a phone in the last 12 months it's likely to be a 5G compatible phone.
- throwaway09223 6y agoI bought a Pixel4 in March 2020 :(
- mfkp 6y agoAssuming you meant Pixel 4a, that one does not have 5G. The "4a 5G" model does, though, but it came out later in the year.
- throwaway09223 6y agoNo, the regular Pixel4. No 5g.
- tobylane 6y agoI’m guessing people who flew into DC on a weekday are more likely than average to own a decent smartphone. QAnon folk don’t seem to avoid mainstream technology in the quantity HN users do.

- ev1 6y agoProbably anyone that has signed a contract that came with a free phone in the last year and a half, anyone upgrading iPhones. Lower cost prepaid carriers are also pushing 5G phones heavily (albeit somewhat crappy ones), and offering them for free.
- nickysielicki 6y agoIt doesn’t matter if you have a 5G device, it is a function of the increased tower density. Those towers are capable of the old frequencies, too.
- diebeforei485 6y agoCould you share some resources with more information on this- how does it increase granularity?
- nexthash 6y agoHere's Verizon's explainer [1] about how 5G works. Basically, since the frequencies needed to transmit large amounts of data are so high (28 - 39 GHz millimeter wavelength bands), the signal does not reach as far as a 4G tower. Therefore, a higher density of towers is needed (500 feet apart to effectively penetrate buildings [2]), allowing for higher granularity cell-phone triangulation/tracking as a by-product.

- Gibbon1 6y agoWell GPS is 1.2 to 1.5GZ and you can get accuracy to a few meters easily. I have a higher end module that gets down to a meter[1]. Seems obvious that G4 which uses roughly same frequencies but with cell towers vastly closer than a GPS satellite could get 1M. [1] Give it a few minutes and it'll pin point where my desk is inside my office.
- BurningFrog 6y agoGPS does not use triangulation. It does some real dark arts physics wizardry to compute a position. Nothing like that can be done for cell phone signals.
- Gibbon1 6y ago> GPS does not use triangulation. LOL
- sobriquet9 6y agoBoth GPS receivers and cell phone towers use the same basic approach based on the time it takes for the signal to travel between transmitter and receiver. The only substantial difference is that in case of GPS the calculation happens on the receiver side (GPS signals only go in one direction), while cellular service providers calculate time advance on the tower side.
