Wi-Fi is a comparatively new sort of technologies that is just

starting to attract a wide following worldwide. Some

think about it to be one particular of the most important innovations

in technology because the world wide web came to the mainstream.

Simply because of it, computers are now capable to connect to the

web and to other computer systems 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). Known as WaveLAN, it was initially intended

to be utilised in money registers.

Numerous competing standards prevented the instant good results

of having wireless networks. Nonetheless, with the development

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

protocol in 1997, this technologies slowly but surely came

into the mainstream.

Since then, several protocols had been released and numerous

much more will be released to address concerns such as range and

speed.

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

Legacy mode, operated in the 2.four GHz frequency. The

throughput and information rate are slow by todays standards,

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

came two years later in 1999 with the a protocol supplying

quicker speeds although the b supplied 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 at present under development. The n, set

to be released mid-2009 offers greater speeds and virtually

double the range of the a/b/g protocols. An additional one particular, the

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

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

of as much as five kilometers. official link
