In 1934, actress and inventor Hedy Lamarr, alongside composer George Antheil, co-patented a "Secret Communication System" designed to combat signal jamming through frequency hopping. Initially met with skepticism due to Lamarr's Hollywood status, the invention was a precursor to Wi-Fi and Bluetooth technology. Initial underestimation by military and technical communities delayed its implementation, but it was eventually recognized as revolutionary, influencing global wireless communication advancements.
