802.11a

Came after the 802.11b standard. Has speeds up to 54 Mbps but is incompatible with 802.11b. Operates in the 5 GHz range.

802.11b

Operates in the 2.4000 and 2.4835 GHz radio frequency ranges, with speeds up to 11 Mbps.

802.11e

Provides standards related to quality of service.

802.11g

Operates in the 2.4 GHz range, with speeds up to 54 Mbps, and is backward compatible with 802.11b.

802.11i

Relates to wireless network security and includes AES (Advanced Encryption Standard) for protecting data.

802.11n

Operates in the 2.4 and 5 GHz ranges and is backward compatible with the older 802.11a, b, and g equipment. Speeds up to 600 Mbps using MIMO antennas. Maximum of four simultaneous data streams.

802.11ac

Operates only in the 5 GHz range, which makes it backward compatible with 802.11n and 802.11a. Speeds up to 6.93 Gbps. Maximum of eight simultaneous data streams using MU-MIMO antennas.

802.11ad

Also known as WiGig and works in the 60 GHz range. Speeds up to 6.76 Gbps.
