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 802.11n works at 108 Mbps. The
802.11n release, has speeds that exceed 802.11g, and up to twice the wireless coverage area.
See the following chart for more detailed information.
*Distance and connection speeds will vary depending on your networking environment.
