What's 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 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 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.
