What's the difference between 802.11b, 802.11g, 802.11a, and
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 11 Mbps; 802.11a and 802.11g work at 54 Mbps; and Pre-N works at 108 Mbps. 802.11n
has speeds that exceed 802.11g, and up to twice the wireless coverage area. See the
following chart for more detailed information.
