Wi-Fi: An important Technology for Communication

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.
