802.11 Wireless Standards

The family of 802.11 standards from IEEE includes several varations on high-speed wireless communication protocols including 802.11a and 802.11b.
802.11a vs 802.11b vs 802.11g Wi-Fi Standards
This article examines the pros and cons of 802.11a, 802.11b, 802.11g, and Bluetooth for WLANs.
Are 802.11b and 802.11g Compatible?
802.11b and 802.11g are both popular standards for Wi-Fi home networking. Can 802.11b and 802.11g gear be mixed on a wireless network, or are they incompatible?
802.11a
802.11a is an established IEEE standard for wireless networking that improves on the performance limitations of 802.11b. 802.11a is a relatively high cost solution found in some business networks.
802.11b
802.11b is an industry-standard technology for wireless communication via Ethernet. Because of its low cost and established history, 802.11b is commonly found in home networks.
802.11n
802.11n is a standard for high-speed Wi-Fi networking, operating at greater than 100 Mbps. 802.11n is designed to replace all of the earlier 802.11a, 802.11b and 802.11g Wi-Fi standards.
802.11 - 802.11 IEEE Networking Standards
802.11 is a family of standards for wireless local area network (WLAN) networking. This page describes each of the "802.11X" standards including 802.11a, 802.11b and 802.11g.
