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�
