The Evolution of WiFi-01 to 07 & Speed From 11 Mbps to 30+ Gbps!

Remember the days when buffering a video felt like forever? WiFi has come a long way from slow, unstable connections to ultra-fast, multi-device networks. Here’s a quick journey through its evolution—from WiFi 1 to WiFi 7!

WiFi 1 (802.11b) – 1999
Speed: 11 Mbps | Band: 2.4 GHz
⚠ Problem: Slow & easily affected by interference.

WiFi 2 (802.11a) – 1999
Speed: 54 Mbps | Band: 5 GHz
Faster, but limited range kept it from mainstream adoption.

WiFi 3 (802.11g) – 2003
Speed: 54 Mbps | Band: 2.4 GHz
Improved compatibility with older devices, but still interference-prone.

WiFi 4 (802.11n) – 2009
Speed: Up to 600 Mbps | Bands: 2.4 GHz & 5 GHz
Breakthrough: MIMO technology allowed multiple data streams, boosting performance.

WiFi 5 (802.11ac) – 2014
Speed: Up to 3.5 Gbps | Band: 5 GHz
Game-Changer: MU-MIMO let multiple devices connect without slowing down the network.

WiFi 6 (802.11ax) – 2019
Speed: Up to 9.6 Gbps | Bands: 2.4 GHz & 5 GHz
⚡ Next-Level Efficiency: OFDMA technology improved performance in crowded networks.

WiFi 6E – 2020
Speed: Same as WiFi 6, but with 6 GHz band
Advantage: Less congestion, better performance in high-density areas.

WiFi 7 (802.11be) – Coming Soon!
Speed: 30+ Gbps | Bands: 2.4 GHz, 5 GHz, 6 GHz
Revolutionary: Multi-Link Operation (MLO) will allow devices to use multiple bands simultaneously for ultra-low latency!

What’s next? With WiFi 7 on the horizon, the future of connectivity is faster, smarter, and more efficient than ever.
