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

beginning to attract a wide following worldwide. Some

contemplate it to be a single of the most significant innovations

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

Since of it, computer systems are now in a position to connect to the

net and to other computer systems wirelessly.

The precursor of todays Wi-Fi was developed sometime in

the early 1990s by the Netherlands-based organization NCR

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

Agere Systems). Called WaveLAN, it was originally intended

to be employed in cash registers.

Many competing requirements prevented the quick accomplishment

of getting wireless networks. Nevertheless, with the development

of the IEEE 802.11 common and the release of its initial

protocol in 1997, this technologies slowly but certainly came

into the mainstream.

Because then, numerous protocols were released and a number of

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 requirements,

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

came two years later in 1999 with the a protocol offering

faster speeds even though 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 provided the

speed of the a and the range of the b.

Newer protocols are presently under development. The n, set

to be released mid-2009 offers higher speeds and almost

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

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

speed as the g protocol even though the y has an outdoor range

of as significantly as five kilometers. [http://hcgprotocol.net/ tell us what you think]
