Oh man, wait till you hear about GPS.
- samstave 4y agoWait until you hear the difference between UPD and TCP.
- MichaelCollins 4y agoI think you might have a point w.r.t. tracking, but you brought up "RF free". There's next to nowhere on earth you can go to escape radio transmissions completely, except a faraday cage or maybe a deep mine. Besides GPS, there's been shortwave radio broadcasts bouncing all over the place for a century.

- LeoPanthera 4y agoI assume they were referring to the "RF free zone" claim. Which is nonsense, since RF noise existed long before humans figured out how to generate it, from storms, or even the sun itself.
- palata 4y agoGPS satellites broadcast data, and the GPS receivers (e.g. your phone) only receive. That means that they are completely invisible to the satellites. You are tracked on your phone because it is connected to the Internet somehow, so it can send your location. But with only a GPS receiver (my Garmin running watch for instance), you are completely invisible.
- boredpudding 4y agoI'm aware of this. I was commenting on the > Think you can be in an RF free zone, anywhere on planet? Nope. It seems OP wants to be 'signal free'. Which, since GPS is already not happening anywhere on the planet.
- samstave 4y agoEverybody seems to focus on the RF free comment... I was talking about towers and such. But I really appreciate the comments. If you have ever been in remote areas, and intrinsically 'felt' a disconnect from the tech world (meaning not near any major RF transducers) let me know... because I have been super remote (arctic circle) etc a bunch and also remote jungle, and I feel a difference. Perhaps placebo mental conditioning, but just curious if anyone else felt the same effect??
