Wi-Fi is a fairly new kind of engineering that is just

starting to attract a wide following worldwide. Some

consider it to be 1 of the most considerable innovations

in technologies given that the world wide web came to the mainstream.

Due to the fact of it, computers are now in a position to connect to the

net and to other computers wirelessly.

The precursor of todays Wi-Fi was created sometime in

the early 1990s by the Netherlands-based company NCR

Corporation/AT&T (which later became known as Lucent &

Agere Systems). Called WaveLAN, it was originally intended

to be utilised in money registers.

Many competing standards prevented the quick success

of possessing wireless networks. However, with the development

of the IEEE 802.11 normal and the release of its very first

protocol in 1997, this technologies slowly but surely came

into the mainstream.

Because then, a number of protocols had been released and a number of

far more will be released to address problems such as range and

speed.

The 1st protocol released in 1997, now identified as the

Legacy mode, operated in the 2.4 GHz frequency. The

throughput and information rate are slow by todays requirements,

with only .9 and 2 Mbit/s, respectively. 802.11 a and b

came two years later in 1999 with the a protocol providing

more quickly speeds whilst the b provided a wider range.

The elements of the two had been later merged in 2003 when the

802.11g protocol was released. The new protocol supplied the

speed of the a and the range of the b.

Newer protocols are presently below development. The n, set

to be released mid-2009 supplies higher speeds and practically

double the range of the a/b/g protocols. Yet another 1, the

802.11y, is set to be released in mid-2008 has the same

speed as the g protocol despite the fact that the y has an outdoor range

of as significantly as 5 kilometers. official link
