Hedy Lamarr was a glamorous Hollywood actress known for her stunning beauty and charisma, but what many people don’t know is that she also made a significant contribution to the development of Wi-Fi technology. In this article, we’ll explore how Hedy Lamarr laid the foundations for modern Wi-Fi 80 years ago.

In 1942, Lamarr and her husband, musician George Antheil, were working on a way to protect their new invention, the "frequency hopping" technology, from being stolen by Nazi Germany during World War II. This technology allowed for the transmission of radio signals over a wide range of frequencies, making it nearly impossible for the enemy to intercept or jam the signal.

However, the military was not interested in Lamarr’s invention, and so she turned to the Federal Communications Commission (FCC) for help. The FCC, impressed by Lamarr’s innovative idea, granted her a patent for the technology in 1945.

Fast forward to the 1960s, when wireless communication was becoming more popular. Researchers at Stanford University noticed that Lamarr’s frequency hopping technology could be adapted for use in Wi-Fi systems. They developed a new protocol called "Carrier Sense Multiple Access with Collision Detection" (CSMA/CD), which allowed multiple devices to communicate over the same frequency without interfering with each other.

In 1983, CSMA/CD was adopted as the standard for Wi-Fi communication, and it has remained the industry standard ever since. Today, Wi-Fi technology is used in billions of devices worldwide, from smartphones to laptops to smart homes. And all of this can be traced back to Hedy Lamarr’s innovative idea and her willingness to fight for its recognition.

Lamarr’s contribution to Wi-Fi technology has been recognized by the Electronic Frontier Foundation (EFF), which has named her one of its "Pioneers" in the field of digital rights and innovation. The EFF also established the Hedy Lamarr Award, which is given annually to individuals who have made significant contributions to the development of free and open technology.

In conclusion, Hedy Lamarr’s unseen contribution to Wi-Fi technology has had a profound impact on our lives today. Her invention laid the foundation for modern wireless communication, and her legacy continues to inspire future generations of innovators in the tech industry. As we move forward into an increasingly connected world, it’s important to recognize and honor the contributions of individuals like Hedy Lamarr who have paved the way for progress.
