This is mostly wrong: while she did invent what would later be called Frequency Hopping Spread Spectrum (FHSS), it isn’t used in modern WiFi or in GPS. It is used in Bluetooth though.
I should point out that techniques like FHSS are only a part of what makes up a radio communication method. You can’t say it was “the basis of Bluetooth” just because FHSS is one of the many technologies used in Bluetooth. She certainly contributed though.
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.
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.

You got me curious, is that true across all the different options for wifi such as 802.11b and a?
Yes, it’s been obsoleted in wifi since 2014. DSSS was always the preferred option and FHSS was never used much in WiFi.
So she’s the reason Apple removed the headphone jack?

fair, rescinded.

Fair enough. I’ll fix that.
