Introduction: WiFi has grow to be a cornerstone of modern-day connectivity, revolutionizing how people have interaction, artwork, and get right of entry to records. From its inception as a wireless community location network (WLAN) famous to its present day characteristic in allowing smart towns and Internet of Things (IoT) ecosystems, WiFi continues to conform, offering quicker speeds, extra reliability, and extra desirable safety.
A Brief History of WiFi
WiFi modified into born from the IEEE 802.Eleven elegant delivered in 1997. Over the decades, it has gone via tremendous modifications:
802.11b (1999): Marked the primary notably adopted WiFi popular, offering hastens to 11 Mbps.
802.11n (2009): Brought essential enhancements with MIMO (Multiple Input, Multiple Output) generation, accomplishing accelerates to 600 Mbps.
WiFi 6 (2019): Introduced the IEEE 802.11ax popular, optimizing network universal performance in crowded environments and growing performance for IoT gadgets.
Each generation has addressed particular demanding situations, together with pace barriers, interference, and scalability, ensuring WiFi remains relevant in an ever-changing technological panorama.
The Role of IEEE in WiFi Innovation
