In Today’s world
there is no need to grab the telephone receiver and dial a specific number to
transmit voice through cables merely to hear the voice of your Friend. Now each
of us carries our own handsets with a built-in phonebook and text messages. The
facilities like Wi-Fi have further improved the standard of communications by
cutting down expenditure and increasing availability.
No matter where you
are, you can access the world of web through your Mobile handsets, Laptops and even
on your Tablets. The technology that enables you to plug in internet without
any wires, no matter you are in a cafe, in a library, in a shopping mall, in college
campus or on any airport, it is all Wi-Fi. The wireless
network also known as 802.11 standard. The circumference where wireless
technology is present and available to the users is known as Hotspot.
The inexpensive,
user-friendly Wi-Fi networks are also conspicuous. Wi-Fi is commonly
installed in home or offices these days, in order to transmit information in
the air without the use of wires. In near future you would find wireless
networking available in every nook and corner of the country due to its demand
and usefulness. And that day is not very far.
Wi-Fi is derived from
the decades old term Hi-Fi that stands for the output’s type produced by
quality music hardware. Wi-Fi Technology is WIRELESS
FIDELITY and stands for all those technologies that fall under the
specifications of IEEE 802.11 including 802.11a, 802.11b and 802.11g. The
association of the term Wi-Fi with various technologies is merely because of
the promotions made by the Wi-Fi Alliance.
Wi-Fi transmits data through radio waves. The two-way radio communication: the wireless adapter translates data into a radio signal then transmits it via antenna; and the signal is received and decoded by the wireless router that uses a tangible wired Ethernet connection to send information to the internet. The equation is reversed when wireless router receives data from the internet and translates it into a signal where the wireless adaptor receives the signal and decodes it.
If your laptops and
cell phones do not have a built-in wireless transmitter then you could purchase
a wireless adaptor and inject it into USB port. A Wi-Fi hotspot is
automatically discovered and connected by the transmitters. The presence of
Wi-Fi in public places makes it convenient to stay connected to your official
tasks or to the social networking.
Thus the Wi-Fi
Technology is very beneficial to always stay connected with your Colleagues, Friends
and Relatives.
