802.11b
(11b) – The 802.11b wireless radio has a range of about 50
meters and a maximum throughput of 11 Mbit/s, however a significant
percentage of this bandwidth is used for communications overhead; in
practice the maximum throughput is about 5.5 Mbit/s. Although it’s
slower than 11g, it’s still the most commonly used network today.

(11g)
-
In June 2003, a third standard for Wi-Fi was ratified:
802.11g. This version works in the 2.4 GHz band (like 802.11b) but
operates at 54 Mbit/s raw, or about 24.7 Mbit/s net, throughput like
802.11a. It is fully backwards compatible with 11b and uses the same
frequencies.

802.11a
(11a) - The 802.11a standard uses the 5 GHz band, and
operates at a raw speed of 54 Mbit/s, with net achievable speeds in
the mid-20 Mbit/s. The speed is reduced to 48, 36, 34, 18, 12, 9 then 6
Mbit/s as required to connect to slower AP’s. 802.11a has 12
non-overlapping channels, 8 dedicated to indoor and 4 to point to
point.
