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 chart on the next page for more
detailed information.
