Hedy Lamarr: The Beautiful Actress Who Invented Wi-Fi

Hedy Lamarr, a Hollywood actress and inventor, said in 1990, ten years before she died, “I think the people’s brains are more fascinating than the appearances of individuals.” She is the reason why we have WIFI now. Get more details on Time fibre unlimited home broadband Malaysia.

The beautiful actress is perhaps best known for her parts in the Oscar-nominated films ‘Algiers’ and ‘Sampson and Delilah,’ both from the 1940s. According to a documentary film on her life called ‘Bombshell: The Hedy Lamarr Story,’ her greatest legacy is her technical mind. The film follows LaMarr’s patent application for frequency-hopping innovation in 1941, which led to the development of secure wi-fi, GPS, and Bluetooth, which are currently utilized by countless people all over the world.

However, life is filled with unexpected twists and turns. Hedy Lamarr had no academic engineering or related schooling.

Her research lab was Hollywood, where she worked as an entertainer and specialized in enthralling audiences with her breathtaking beauty. She also possesses a patent for a jam-resistant torpedo control frequency-hopping radio communication system.

An Inquisitive Mind

Despite the fact that Lamarr never attended college and had been a film actor at the age of 16, she was a clever young woman whose passion in science had been nurtured by her father since she was a child.

Lamarr’s inherently creative and curious mind was nurtured by numerous activities, despite the fact that her young adulthood is engaged significantly more with film sets than it is with STEM experiments. 

Spectrum hopping as well as other forms of spread-spectrum technology were later implemented into several RF protocols including systems, including IEEE 802.11 (widely known as Wi-Fi), Bluetooth, GPS by satellite, and cell towers, from torpedoes to Wi-Fi and beyond. The current landscape of fast, reliable, and easily accessible wireless communication would not exist without the pioneering work of Hedy Lamarr and other 20th century pioneers.

War Effort 

In the year 1940, Lamarr was keen to help in the war effort. She was well aware that radio-controlled torpedoes may be important in naval action, but that they were also vulnerable to jamming—that is, purposely created RF interference.

To create an effective terminal access controller access control, the attacker must broadcast enough RF energy at the carrier frequency of the target equipment. Depending on the context, this task may be simple or tough. This was realized by Lamarr, who came up with the concept of a frequency-hopping radio system.

Lamarr’s work is a test case in the seamless fusion of science and art, as well as a tribute to the human mind’s diverse and adaptable genius. She is an encouragement to individuals who seek knowledge and success outside of their professional or academic fields.

Her Talent isn’t Celebrated 

What didn’t come easy to LaMarr was the fame and money she earned for her ideas. The patent she and co-inventor George Antheil filed attempted to safeguard their wartime invention for radio transmissions that could ‘hop’ from one frequency to the other, making it impossible for Nazis to locate Allied torpedoes. Despite the fact that the United States military has officially acknowledged her resonance patent and contribution to technology, neither LaMarr nor her family have received a penny from the multibillion-dollar industry her concept cleared the way for.
