Summarizing the IEEE 802.11 Wi-Fi standards

IEEE 802.11
The first Wi-Fi standard operating at 2.4 GHz with a maximum speed of 2 Mbps and a range of ~20 meters indoors. Set the foundation for wireless networking.

IEEE 802.11a
Uses the 5 GHz band with a speed of 54 Mbps and a range of ~35 meters indoors. Offers faster speeds but shorter range compared to 802.11.

IEEE 802.11b
Operates in the 2.4 GHz band, delivering speeds of up to 11 Mbps and a range of ~35 meters indoors. Prone to interference but provided greater reach.

IEEE 802.11g
Backwards compatible with 802.11b, offering speeds up to 54 Mbps on the 2.4 GHz band with a similar range of ~35 meters indoors.

IEEE 802.11n
Supports both 2.4 GHz and 5 GHz bands, with speeds up to 600 Mbps using MIMO technology. Extended indoor range of ~70 meters.

⚡ IEEE 802.11ac
Operates on the 5 GHz band with speeds up to 1.3 Gbps. Introduced MU-MIMO and wider channels for faster and more efficient performance.

IEEE 802.11ad
Uses the 60 GHz band for ultra-high speeds of up to 6.7 Gbps but a short range of ~10 meters indoors. Ideal for specialized high-speed use cases.

IEEE 802.11ax (Wi-Fi 6)
Supports 2.4 GHz and 5 GHz bands with speeds up to 9.6 Gbps. Enhanced efficiency for dense environments like offices and stadiums.

IEEE 802.11be (Wi-Fi 7)
Operates across 2.4 GHz, 5 GHz, and 6 GHz bands with theoretical speeds of up to 46 Gbps. Offers ultra-low latency and advanced MIMO capabilities.

IEEE 802.11ah
Uses sub-1 GHz frequencies, reaching speeds of 347 Mbps with an extended outdoor range of up to 1 km. Designed for IoT and low-power devices.

IEEE 802.11af
Utilizes unused TV white space in UHF/VHF bands, delivering speeds of 568 Mbps over a long range of ~1 km. Ideal for rural broadband deployment.

IEEE 802.11ax (Wi-Fi 6E)
Extends Wi-Fi 6 to the 6 GHz band, providing speeds up to 9.6 Gbps with reduced congestion and improved performance in crowded environments.
