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
