A Brief Overview of Wi-Fi Evolution
Since its inception in the late 1990s, Wi-Fi has continually evolved to meet the growing demands of users. The journey began with the IEEE 802.11 standard, offering modest speeds suitable for basic tasks. Over the years, newer standards like Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), and Wi-Fi 6 (802.11ax) have pushed the boundaries of speed, efficiency, and device capacity.
- Wi-Fi 4 (802.11n): Introduced MIMO (Multiple Input Multiple Output) technology, boosting data rates.
- Wi-Fi 5 (802.11ac): Brought higher throughput and the introduction of the 5 GHz band.
- Wi-Fi 6 (802.11ax): Focused on improving efficiency in dense environments, enabling faster and more stable connections.
- Wi-Fi 6E: Extended Wi-Fi 6 capabilities to the 6 GHz band for less congestion and higher speeds.
Now, with Wi-Fi 7 (802.11be) on the horizon, the potential for even greater innovations is becoming a reality.
