What is the difference between 802�11b, 802�11g, 802�11a, and
draft-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 Draft-N works up
to 300Mbps� Draft-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�
