What's the difference between 802.11b, 802.11g, 802.11a, and 802.11n?

Currently there are four levels of wireless networking standards, which transmit data at very different maximum speeds. Each is based on the designation for certifying network standards. The most common wireless networking standard, 802.11b, transmits information at 11 Mbps; 802.11a and 802.11g work at 54 Mbps; and 802.11n works at 108 Mbps. The 802.11n release, has speeds that exceed 802.11g, and up to twice the wireless coverage area. See the following chart for more detailed information.
