It was hardly ever used in WiFi. Two spread spectrum schemes were available in the original WiFi spec, FHSS and DSSS. DSSS was always preferred over FHSS and in practice FHSS was hardly used and eventually obsoleted a decade ago due to lack of use. It was never "the basis" of WiFi as claimed in the meme - that's simply incorrect.

Don't get me wrong. FHSS is cool and it's a great achievement. It just has little bearing on WiFi and absolutely no relationship to GPS.

Better examples of FHSS would be Bluetooth (which you already mentioned), cordless phones, R/C toys and some military communications.

fair, rescinded.

you did put a false quote in your top comment tho. thats my main issue: “invented bluetooth/wifi” was nowhere in the original post. that’s a straw position you constructed yourself then took down easily because obviously it’s not true.

Fair enough. I'll fix that.
