Who invented frequency hopping

Shortly thereafter, she secures a contract with MGM and moves to Hollywood. As the U. Her marriage to Mandl, a key player in providing weapons to the Axis powers, proved valuable.

The couple often hosted dinner parties that included top-ranking Nazi and fascist officials. Her husband was in close contact with both Adolph Hitler and Benito Mussolini, both of which Lamarr met. Understanding the type of military technology the enemy used produced her idea for the frequency hopping signal.

Because of this, people should mention Hedy Lamarr and WiFi in the same breath. Lamarr makes a string of other films. However, she received fewer leading roles, and eventually ended her movie-making career in Following her tenure as a Hollywood actress, Lamarr gave a few interviews and even had an autobiography published in her name although she later sued the ghostwriter for saying most of the book was fiction. Sadly, the remainder of her life carried a melancholy tune. She had a total of six marriages, lost the relationship with her son, went to jail for shoplifting, never received the compensation she deserved for her key invention , and lived her later years in life as a recluse.

She passed away in As requested, her family spread her ashes in Vienna, at the foothills of the Northern Alps. Inventing was her method of switching from entertainer to entertained. Her mind was full of infinite possibilities. There was always something to learn, redesign, make excellent, or advance forward.

However, the marriage afforded her the opportunity to rub elbows with German generals and admirals, which is probably where she first heard about military technology. During World War II, Lamarr partnered with George Anthiel, who used his knowledge of player pianos to help her come up with a workable concept. Their patent is the basis of modern cellphone technology.

Their communication system was not implemented in the USA until , when it was used by U. However, rather than being used for torpedoes, it was used to provide secure communications between ships used in the blockade. Today, the frequency-hopping science presented in the patent serves as the basis for modern spread-spectrum communication technology Bluetooth, Wi-Fi, etc. She is obviously NOT the ugly! It will comment briefly on Bluetooth architecture. A following series will relate Bluetooth and other wireless connections to hearing aid devices.
