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.

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.
