Wi-Fi is a comparatively new type of engineering that is just

beginning to attract a wide following worldwide. Some

contemplate it to be a single of the most considerable innovations

in technologies because the net came to the mainstream.

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

internet and to other computers wirelessly.

The precursor of todays Wi-Fi was developed sometime in

the early 1990s by the Netherlands-based firm NCR

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

Agere Systems). Known as WaveLAN, it was initially intended

to be utilised in cash registers.

Numerous competing standards prevented the quick achievement

of getting wireless networks. However, with the development

of the IEEE 802.11 common and the release of its first

protocol in 1997, this technology slowly but surely came

into the mainstream.

Because then, many protocols had been released and several

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

speed.

The first protocol released in 1997, now known as the

Legacy mode, operated in the two.4 GHz frequency. The

throughput and information rate are slow by todays requirements,

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

came two years later in 1999 with the a protocol supplying

faster speeds although the b offered a wider range.

The elements of the two were 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 higher speeds and practically

double the range of the a/b/g protocols. One more one, the

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

speed as the g protocol although the y has an outdoor range

of as significantly as 5 kilometers. tell us what you think
