#2Frequency hopping is no small idea to crack because you either need a
shared codebook (PRNG) or a means of re-keying to an ephemeral window
of future sequences. Didn't read Lamarr's patent but she seems a
natural hacker girl taking music boxes apart aged 5.

#3Like many stories of this kind, the idea that this person "pioneered the basis" of these technologies seems massively overblown. What she and Antheil patented was a system that used frequency hopping to help guide torpedoes, using a piano roll to switch between the frequencies. They did not "invent" frequency hopping, which had been discussed in the literature for 30 years already.

But a piano-roll (presumably of type she discovered in music boxes) is
quite ingenious solution for synchronised key sequences, for the
technology of the time. Kinda similar analogical transfer going on for
the Jacquard loom as early "program storage".

#5Wlan is not using frequency hopping or am I mistaken?

exactly. every single one of these cases is an absolute stretch and diminishes the work of the people who actually developed it. its historical revisionism at best
at worst its offensive to the person because it suggests they were so small minded that they didn't or couldn't actually develop the technology to a sufficient enough degree such that they are actually associated with it. these people are hidden not because they're women, but because they didn't really contribute anything at all to the field

#7Note that this "Austrian-American actress" (I understand the helpful wording is aimed at non-buffs who may not recognise the name Hedy Lamarr) was a huge star in her day, an equivalent to - say - Margot Robbie.

Yes, otherwise interference would be a right pain (or render it unusable completely). This happens for many wireless systems (like bluetooth too).

Bigger than Robbie, much bigger

Got her own joke name in Blazing Saddles. No greater honour.
