From invention to ubiquity—key milestones that shaped wireless internet.
The Wi-Fi Evolution Timeline highlights key milestones, starting with 1971's ALOHAnet pioneering wireless data, the 1997 IEEE 802.11 standard's release, and 1999's Wi-Fi Alliance founding for global compatibility. It progresses to 2010s synergy with 5G for seamless connectivity and today's Wi-Fi 7 revolutionizing speeds and low latency.
1971: ALOHAnet: First Packet Network Hawaii's ALOHAnet pioneered wireless data communication, laying Wi-Fi foundations. 1997: IEEE 802.11 Standard Born First WLAN standard released, birthing the technology behind modern Wi-Fi. 1999: Wi-Fi Alliance Founded Group trademarks 'Wi-Fi,' ensures device compatibility worldwide. 2010s: 5G and Wi-Fi Synergy Wi-Fi partners with 5G for hybrid, seamless connectivity everywhere. Today: Wi-Fi 7 Revolutionizes Speeds Ultra-fast, low-latency Wi-Fi 7 transforms daily wireless experiences.
This slide, titled "Pioneers of Wi-Fi," features Hedy Lamarr as an actress and inventor. It highlights her 1942 frequency-hopping patent for torpedoes, which inspired Wi-Fi's spread spectrum technology, marking her transition from Hollywood to wireless pioneer.
