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

Currently there are three levels of wireless networking standards,
which transmit data at very different maximum speeds. Each is
based on the designation 802.11x, 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. See
the following chart for more detailed information.
