In 1990, the frequency-hopping spread spectrum (FHSS) technology, initially designed for military communication security by Hedy Lamarr and patented in 1942, entered the commercial sphere. This advancement significantly impacted wireless communication by facilitating secure and efficient data transfer, serving as a foundational technology for Bluetooth and Wi-Fi. Lamarr’s contribution played a crucial role in enhancing telecommunications and internet connectivity, fundamentally shaping information technology and personal communication.
