What is the difference between 802.11b, 802.11g, 802.11a, and Pre-N?

Currently there are four levels of wireless networking standards, which

transmit data at very different maximum speeds. Each is based on

the designation 802.11(x), so named by the IEEE, the board that is

responsible for certifying networking standards. The most common

wireless networking standard, 802.11b, transmits information at

11Mbps; 802.11a and 802.11g work at 54Mbps; and Pre-N works

at 108Mbps. Pre-N, the precursor to the upcoming 802.11n release,

promises speeds that exceed 802.11g, and up to twice the wireless

coverage area. See the following chart for more detailed information.
