What’s your evidence, Richard Easton??!?
Wifi doesn’t use frequency hopping. That’s bluetooth.

Frequency Hopping Spread Spectrum PHY of the 802.11 Wireless LAN Standard
Edit: h3ndrik@feddit.de is correct. FHSS was quickly dropped for DSSS and OFDM, and FHSS is not used in any modern WiFi specs. You can see the list in table 7.6 here https://www.pearsonitcertification.com/articles/article.aspx?p=1329709&seqNum=4
It may be dropped, but it was used in the beginning
Wouldn’t that not still make her the mother of Wifi?
It’s a brief five-minute Google search for me, but it seems that everyone has problems with both reading comprehension and/or causality evaluation.
I think it’s great that such a patent exists and that the technology was invented by her. Yet, even checking the frequency-hopping spread spectrum page on Wikipedia shows that it was only one invention in the long series of discoveries and technologies, which was neither the first, nor the most crucial of them, and this particular option seems to be one of the sources of inspiration for later technologies (along with a bunch of predecessors).
The rest of the criticisms regarding the choice of Wi-Fi over Bluetooth is already mentioned in the comments of others.
I really don’t want to minimise the contribution of an individual towards the development of sophisticated technologies, and I have zero qualms about this individual being a woman, I just think that the presentation oversells the achievement which might cause additional mockery from those who do think that women (and actresses at that!) have no business in anything serious.
What I actually find impressive, however, is that a woman, at the time where women’s rights were far from what they are today (just read about her first marriage, that must have been hard), could be both an actress, an inventor, a producer, all while leading quite a bitter life it seems. Not many can boast that.
I guess where I’m going with that is that she, as many others, may be best praised as an example of a complex person that had many achievements as well as many hardships. Using her as a basis of “Didn’t think an actress could do something worthwhile? Gotcha!” statement seems a bit shallow.
edit: However, since this post showed me that a person like Hedy Lamarr has existed in the first place (yeah, I’m not well-versed in mid-20 century American culture, sorry), and interested me (and likely a bunch of others) enough to Google her biography, I’d say it’s a net positive regardless.
Don’t try and oversell “famous woman does tech thing”. Try and and make people aware of the women who actually did really cool tech things. Marie Curie was a bad ass
This post is inaccurate. Neither WiFi nor GPS use FHSS, nor is Lamarr anything close to singularly credited with FHSS’ invention (the earliest patent is credited to Nikola Tesla). This also implies that the Allies used her parent - they did not.
Also Richard Easton is the son of the man who invented GPS and had every right to be skeptical of this claim, and it looks like Internet dipsh*ts have bullied him into deleting his twitter account over this.
