The IEEE802.11 Criterion as well as Its Protocols
It was in 1997 when the Institute of Electrical and
Electronic Devices Engineers (IEEE) produced the standard for
cordless local location networks (WLANs).
The typical became called IEEE802.11, with the 802.11
coming from the name of the group who managed its
growth. Under this criterion are a number of procedures
established for many years.
Below is a listing of them.
1. 802.11
– also known as the Heritage procedure, this is the original
protocol created in 1997. It operates at 2.4 GHz and has a.
data rate of 1 and also 2 Mbit/s. Its array was restricted to 20 m.
and also 100 m, in interior and also outside setups, specifically.
2. 802.11 a.
– was launched in 1999. It runs at 5 GHz to relocate away.
from the 2.4 GHz operating frequency of the Legacy. Its.
range just provides a mild renovation from its precursor.
with a series of 35 m indoors as well as 120 m outdoors. It is,.
however, quick with a data rate of 54 Mbit/s.
3. 802.11 b.
– additionally released in 1999. Much like the Legacy, it runs.
at 2.4 GHz. It has a slightly greater variety than the.
802.11 a, but is slower. The b only has a data price of 11.
Mbit/s.
4. 802.11 g.
– marries the attributes of the an and the b. It has a.
information rate of 54 Mbit/s like an as well as has the very same range as the.
b with 38 m inside your home as well as 140 m outdoors. It was launched in.
2003.
5. 802.11 n.
– is established to be released on June 2009. It can operate.
either 2.4 or 5 GHz frequencies. It is fast with a data.
price of 248 Mbit/s as well as has an indoor series of 70 m and also up.
to 250 m outdoors.
