What's the difference between 802.11b, 802.11g, 802.11a, and
draft 802.11n?
Currently there are four levels of wireless networking standards,
which transmit data at very different maximum speeds. Each is
based on the designation for certifying network standards. The
most common wireless networking standard, 802.11b, transmits
information at 11Mbps; 802.11a and 802.11g work at 54Mbps; and
draft 802.11n works at 108Mbps. See the chart on the next page for
more detailed information.
