So she’s the reason Apple removed the headphone jack?
Comment on Recognize the mother of Wifi

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. (It was an option in older WiFi for a while)

It was hardly ever used in WiFi. Two modulation 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. It was never “the basis” of WiFi as claimed in the meme - that’s simply incorrect.

fair, rescinded.
you did put a false quote in your top comment tho. thats my main issue: “invented 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.

As written it’s an amazingly impressive claim, but it’s absolutely wrong as I understood it.
It sounds like it’d be much more accurate to say she invented FHSS a foundational technology used in x,y,z

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
