  From the wiki page

  During the late 1930s, Lamarr attended arms deals with her then-husband arms dealer Fritz Mandl, “possibly to improve his chances of making a sale”.[41] From the meetings, she learned that navies needed “a way to guide a torpedo as it raced through the water.” Radio control had been proposed. However, an enemy might be able to jam such a torpedo’s guidance system and set it off course.[42] When later discussing this with a new friend, composer and pianist George Antheil, her idea to prevent jamming by frequency hopping met Antheil’s previous work in music. In that earlier work, Antheil attempted synchronizing note-hopping in the avant-garde piece written as a score for the film Ballet Mechanique that involved multiple synchronized player pianos. Antheil’s idea in the piece was to synchronize the start time of identical player pianos with identical player piano rolls, so the pianos would be playing in time with one another. Together, they realized that radio frequencies could be changed similarly, using the same kind of mechanism, but miniaturized.[4][41]

  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.

      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.

      Capacitive touchscreens are a big deal but it kind of minimizes the work of the other technology that goes into a smartphone, like wireless internet, low power mobile CPUs capable of 3D graphics, lithium-ion battery packs, etc., to say nothing of the design engineers that worked on the exterior, the hardware, and the operating system. Crediting the holder of a patent from over 40 years before the iPhone hit the market with the creation of the iPhone is stretching the truth at best.

    I’m from a Tech and Science background (unfinished Physics degree, most-definitelly-finished EE degree and then about 2 decades at the bleeding edge of Informatics) and some years ago came in contact with the Theatre Acting world for a couple of years whilst living in London (UK), doing various short courses, seeing fringe Theatre and getting acquainted with various (not famous) actors and directors.

    Most were surprisingly (for me, at the time, with my pre-made ideas from my Science background and 2 decades in Tech) intelligent people.

    Good acting using modern acting techniques and good directing do require quite a lot of brains to pull do well, IMHO, since in things like method acting well before there’s any acting of what’s on a script, there’s a whole process of analysing them and various techniques for discovering the emotions of the character (best I can describe in a short space), at least for stage acting.

    The only main difference in capabilities, I would say, is that at least in Acting there is a much higher proportion of Extroverts than Introverts, the very opposite of the proportion in Science and Tech, and Introverts are the ones with the personality type that’s detailed oriented and hence more likely to come up with things like new or changed processes for doing things (IMHO).

  Note that this frequency hopping is no longer used in most WiFi networks today. It is, however, critical to classic Bluetooth, and BLE still somewhat uses it. I have no idea how it’s related to GPS.

  source

  • Socsa@sh.itjust.works ⁨1⁩ ⁨year⁩ ago

    Frequency hopping in wifi was never well supported. 802.11a was primarily DSSS and afaik, very few, if any consumer devices supported the FHSS mode.

    source

    • henfredemars@infosec.pub ⁨1⁩ ⁨year⁩ ago

      Indeed. Just speaking from a signals point of view, frequency hopping is not competitive for high bandwidth applications. It is however surprisingly durable in the presence of interference despite its simplicity. We’re seeing this play out in newer Bluetooth standards.

  Great to recognise this invention.

  I was surprised by the choice of ‘Mother of Wi-Fi’ though - Wi-Fi hasn’t used ‘frequency hopping’ as such since 802.11b was released back in 1999 - so very few people will have ever used frequency-hopping Wi-Fi.

  GPS only uses it in some extreme cases I think, but I’m not an expert.

  However, Bluetooth absolutely does depend on it to function in most situations, so ‘Mother of Bluetooth’ might have been more appropriate.

  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.

  Okay, well, I’m a network professional with a specialty in wireless and a keen interest in historical wireless networking, and “non-standard” stuff is also quite interesting. I’m no Richard Easton.

  I want to start with a disclaimer, by no means would I, nor should I be interpreted to be saying or implying that any contribution, regardless of source, isn’t valuable. Whether it comes from a woman, or man, white, black, or any color in-between, non-binary, gay, bi, trans, whatever. The contributor is valuable and their contribution is always valued.

  That being said, FHSS, has its uses, and it’s been used in wireless. It’s a valid technology that should be recognised as such. As with many things, it wasn’t a singular effort, and nobody should imply otherwise.

  As others have pointed out, the most commonly known technology which employs FHSS is Bluetooth; and trust me, trying to track down issues caused by BT interference is a nightmare because of it. Generally I avoid the problem by not using the 2.4ghz ISM band as much as possible, but I digress.

  For those saying it’s not part of 802.11, it actually is. It’s an old part of the protocol which has long since been replaced and it is considered obsolete by the IEEE 802.11 group.

  However, in the 802.11 protocol, sometimes called 802.11 prime (Wikipedia calls it “legacy”), it states: “[802.11] specified two raw data rates of 1 and 2 megabits per second (Mbit/s) to be transmitted via infrared (IR) signals or by either frequency hopping or direct-sequence spread spectrum (DSSS) in the Industrial Scientific Medical frequency band at 2.4 GHz.” en.wikipedia.org/wiki/IEEE_802.11_(legacy_mode)

  All I want to really add, is that networking is a team sport. If companies and people didn’t work together to make it function, then it wouldn’t work.

  Only by collaborating and working together towards improvement and an increase in the ability of the technology to work across all platforms, vendors, manufacturers, and devices, can we get it to function at all. This fact is as true now as it was when FHSS was invented. Everyone needs to work together in order to make any real progress. Otherwise, all of our wifi stuff would “speak” different languages, and nothing outside of a single companies product line, would work with anything else.

  Everyone’s contributions have helped wifi get to it’s current state, and that should never be forgotten.
