Smudge The Insult Cat 🐀
Henning Paul DC4HP@SmudgeTheInsultCat FFS, no, for the hundredth time: Hedy didn't make WiFi, she invented FHSS, which isn't used by WiFi, but by Bluetooth.
MarkAssPandi@hennichodernich @SmudgeTheInsultCat Both use it. Bluetooth uses it more, for performance, but WiFi does use it as well, it's allowed in 2.4GHz band.
Marcus Müller@MarkAssPandi @SmudgeTheInsultCat @hennichodernich no, it really doesn't. Wi-Fi in old standards did use a spread spectrum method, DSSS, but Hedy Lamarr invented frequency spread spectrum, which is really something completely different.
@funkylab @SmudgeTheInsultCat @hennichodernich I might remember wrong but didn't original 802.11 standard allowed both DSSS and FHSS? Just DSSS won in common use
@funkylab @SmudgeTheInsultCat @hennichodernich Yeah I was wrong about it still being used, my bad
But it was part of the first spec, but became obsolite
But yeah in general I was kinda wrong lol my bad

@MarkAssPandi @SmudgeTheInsultCat @hennichodernich happens! For those who don't want to look this up themselves:
The first IEEE 802.11 standard, IEEE801.11-1997, did indeed have an FHSS mode.
That was, however, *never* "wifi", as far as I can tell, because "Wi-Fi" as a "brand" for a specific group of wireless network technologies was branded in 1999, and was first applied to IEEE802.11b and 802.11a, neither of which have the FHSS mode.
