The IEEE 802.11 is a wireless LAN industry standard, and the objective of IEEE 802.11
is to make sure that different manufactures' wireless LAN devices can communicate
to each other.802.11 provides 1 or 2 Mbps transmission in the 2.4 GHz ISM band
using either FHSS or DSSS.
What is 802.11b?
802.11b is the first revision of 802.11 standard allowing data rates up to 11Mbps in
the 2.4GHz ISM band. Also known as 802.11 High-Rate and Wi-Fi. 802.11b only uses
DSSS, the maximum speed of 11Mbps has fallbacks to 5.5, 2 and 1Mbps.
How fast is 802.11b?
The IEEE 802.11b standard has a nominal speed of 11 megabits per second (Mbps).
However, depending on signal quality and how many other people are using the
wireless Ethernet through a particular Access Point, usable speed will be much less
(on the order of 4 or 5 Mbps, which is still substantially faster than most dialup, cable
and DSL modems).
What is 802.11a?
802.11a the second revision of 802.11 that operates in the unlicensed 5 GHz band
and allows transmission rates of up to 54Mbps. 802.11a uses O FDM (orthogonal
frequency division multiplexing) as opposed to FHSS or DSSS. Higher data rates are
possible by combining channels. Due to higher frequency, range is less than lower
frequency systems (i.e., 802.11b and 802.11g) and can increase the cost of the
overall solution because a greater number of access points may be required. 802.11a
is not directly compatible with 802.11b or 802.11g networks. In other words, a user
equipped with an 802.11b or 802.11g radio card will not be able to interface directly
to an 802.11a access point. Multi-mode NICs will solve this problem.
