What is the difference between 802�11b, 802�11g, 802�11a, and 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 N works at 300Mbps. See the
following chart for more detailed information.
