Does it defraculate?

28Ghz?!? WOAHkeanu.jiff What did they do?!!, idk did they strap, like, eight top-end pentium 4's together, or something, and what kind of epic heatsink was needed to just run Crysis on medium??

5G's use of phased array beam forming techniques work best if they know exactly where you are so that they don't get confused by signals from other locations.

This is how 5G tracks you. They don't need implanted chips.

No.  The complexity and high power consumption of defraculation was rendered unnecessary by exploiting the modial interaction of magnetoreluctance and capacitive directance.

Well, they only know the direction, until you move to another array. Which with 5G will happen every 150 meters or so.  Very short range.

While you could track someone at least in 1D - most MIMO transeivers use a vertical array of dipoles to steer the beam "left to right" as people call it - by measuring fade as you walk out of one beam lobe and into the next, I think it'd be more accurate to say this is WHY 5G tracks you.

The how is more of simple triangulation off of towers... Just like 4G. And 3G. And 2G.

Yes but coverage in the Ka band is very problematic - you need waveguides to transmit at 28 ghz and line of sight.

The implanted chips help warm your balls on cold days.

/Don't disparage the implanted chips.

You do realize, of course, that the black helicopters are about to begin circulating around your current location and that an entire SEAL team in inbound to your location, right?

The antenna might be a phased array, but the transceiver itself is not.

A technology susceptible to hackers shutting down entire countries isn't an advance.

Your cellphone regularly pings all of the cell towers within range.  You can fairly accurate determine location by direction and signal strength at each of the towers.  It's not GPS-like accuracy, but it's accurate enough unless you're in a fringe area.
