Thank the late movie star Hedy Lamarr for Wi-Fi, Bluetooth and 4G LTE
Next time you are using Wi-Fi on your cellphone, or connected to a 4G LTE signal, keep in mind that the person you need to thank for these innovations is an actress who received a patent in 1942 for "spread spectrum technology" that is currently used in Wi-Fi, Bluetooth and LTE technology. The actress was born in Austria as Hedwig Kiesler and you might know her as Hedy Lamarr.

Besides her talents as an actress, Lamarr happened to be born with an incredible mind. After marrying one of the richest men in Austria, Friedrich Mandl, she would end up at her husband's side as he would have dinner with men like Hitler and Mussolini. Mandl was the largest arms manufacturer in Austria and the topic at the dinner table would sometimes revolve around radio-controlled missiles and torpedoes.

While pretending to be bored at these dinners, Lamarr actually soaked up the information. After running off to America, she became one of the country's biggest movie stars toiling for MGM during the 1940's. But at the same time, she developed a wireless communication system that couldn't be jammed. Her goal was to help the Allies defeat the Nazis. Back then, most wireless systems used one frequency which made it easy to block. The actress came up with a way for the message to be sent over another frequency if the original one was jammed. "Frequency hopping" was the term that was used to describe the technology.

It is hard to believe that the seeds of today's cutting edge mobile technology were planted all the way back during World War II by an actress who was known more for her contribution to Hollywood. And while her movies still are found on cable, her legacy really revolves around the smartphone you are holding in your hand.

Wow! I'm surprised that this isn't more widely known !

That's because it is simply false.

Wrong again. Tesla and others later came up with the technology and Hedy Lamar only had added frequency coordination via "paper player piano rolls" for torpedoes, which btw, *was never used*. I think you are a bit off in your article. But not surprised. It is actually pretty pathetic, because LTE and other newer forms of wireless technologies employ much more than SST, and rely on stuff like CDMA, which btw, is also ancient technology but made workable only in the past decade. Try making sure you do basic research before thinking CBS is right. These kind of people are the ones who said apple invented the mp3 player.

The player pianos were a inspiration, true. But she was awarded the patent. And by the way, more sources besides CBS had the same exact story. Regards, Alan F.

She was awarded a patent, true. Does this patent have ANYTHING to do with wifi, LTE or any current technology? NO! You'd have a much easier time convincing people that Tesla had a role in just about everything we do today, like AC transmission of electricity and a heck of a lot of other stuff. Hedy Lamar had little to nothing to do with anything we have today, and was NOT a forerunner of SST.

sprockkets, It's a fact that Hedy Lamarr has invented frequency hopping which is the base for CDMA (as opposed TDM) and WIFI. Most modern communication systems use band of frequencies to transmit and receive signal. Please educate yourself about differences of CDMA and TDM before posting. Tesla was a great inventor and so were many other people.

She didn't invent SST, she and her associate came up with a "method" to implement SST using piano paper rolls as a way to control it on both ends. We don't use her method whatsoever to do use SST, and for that matter, NO ONE USED THEIR INVENTION. PERIOD! Saying thusly she INVENTED SST is completely FALSE. SST was in use before she even did her work.

If her pattent is as worthless as you say it is, why is it referenced in about 68 other pattents. See the footer of her actual pattent. Search for US2292387 to read details of her pattent.

That's because a lot of patents reference others, and in many cases simply said "this person came up with this method to utilize x (in this case their method of employing SST), but we chose y improvement OR z difference. It happens all the time.

She did have the first onscreen female orgasm. Those on Android can Google this under her name. Those with iPhones will need to "Siri, what is a female orgasm?"

Siri's reply: "I don't know. My boyfriend uses Apple products. Ask an Android user."

Siri would respond "Ask Cortana, I don't know anything about females. My programmers have never been with one."

How do they know she didn't just over hear the whole idea at dinner and tell the Americans its her idea???? Pretty sketchy to me
