The Evolution of WiFi

Summary

Wi-Fi technology has come a long way from its early days. Starting with Nikola Tesla’s vision and Hedy Lamarr’s invention of frequency hopping, Wi-Fi evolved from a simple concept to a critical part of modern life. Early versions struggled with interference and poor coverage, but advancements like Wi-Fi 4, 5, and especially Wi-Fi 6 have addressed these issues. Wi-Fi 6 offers faster speeds, better efficiency, and wider coverage, making it ideal for households with many connected devices. With Wi-Fi 6, streaming, large downloads, and smart home devices can all work seamlessly together, enhancing our daily internet experience.
