| - **Wi-Fi 0 (Experimental)**: Early experiments in wireless networking conducted before the formalization of Wi-Fi standards, typically using the 2.4 GHz band. |
| |
| |
| - **Wi-Fi 1 (802.11b)**: Introduced basic wireless networking in the 2.4 GHz band with data rates up to 11 Mbps. |
| |
| - **Wi-Fi 2 (802.11a)**: Utilized the less crowded 5 GHz band, offering higher data rates up to 54 Mbps and introducing OFDM modulation. |
| |
| - **Wi-Fi 3 (802.11g)**: Combined the speed of Wi-Fi 2 (802.11a) with the compatibility of Wi-Fi 1 (802.11b), operating in the 2.4 GHz band. |
| |
| - **Wi-Fi 4 (802.11n)**: Introduced MIMO (Multiple Input Multiple Output), channel bonding, and beamforming, providing data rates up to 600 Mbps and operating in both 2.4 GHz and 5 GHz bands. |
| |
| - **Wi-Fi 5 (802.11ac)**: Utilized wider channels, MU-MIMO (Multi-User MIMO), and beamforming, offering data rates up to 3.5 Gbps in the 5 GHz band. |
| |
| - **Wi-Fi 6 (802.11ax)**: Introduced OFDMA (Orthogonal Frequency Division Multiple Access), target wake time, and improved MU-MIMO, providing data rates up to 9.6 Gbps in both 2.4 GHz and 5 GHz bands. |
| |
| - **Wi-Fi 6E (802.11ax)**: Utilizes the newly opened 6 GHz frequency band, offering the same features as Wi-Fi 6 (802.11ax) with additional spectrum for higher performance and less interference. |
| |
| |
| - **Wi-Fi 7 (802.11be)**: Expected to offer significantly enhanced efficiency, reduced latency, and improved coverage compared to previous generations, operating in the 2.4 GHz, 5 GHz, and 6 GHz bands. |
| |
| - **Wi-Fi 8 (802.11bf)**: Projected to utilize advanced modulation techniques and provide data rates up to 240 Gbps, along with enhanced multi-user experiences, operating in the 2.4 GHz, 5 GHz, and 6 GHz bands. |
