The fast paced technology has changed the world as well as its habitants. In Today’s global village 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 a beloved. 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 handsets and your laptops and your iPads. You might not have noticed what it is but the technology that enables you to plug in internet without any wires whether you are in a cafe, a library, a shopping mall or an airport is Wi-Fi – the wireless network also known as 802.11. The circumference where wireless technology is present and available to the users is known as Hotspot. The inexpensive, user-friendly WiFi networks are also obtrusive; if you do not need one you would not know there exists any. Wi-Fi could be also installed in home or offices in order to transmit information over the air without the aid of wires. In near future you would find wireless networking available in every nook and corner.
Wi-Fi is derived from the decades old term Hi-Fi that stands for the output’s type produced by quality music hardware. WiFi 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.
For those whose 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.
Wi-Fi is also associated with 802.11 networking. The reference is derived from IEEE – Institute of Electrical and Electronics Engineers uses the numbering system for classifying a range of technological protocols.
Wi-Fi steps into the boots of TV and radio in order to transmit 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.
Wi-Fi communication devices are extended forms of radios used for cell phones and walkie-talkies: they simultaneously transmit and receive radio waves and convert 1s to 0s into the radio waves along with reconverting the radio waves into 1s and 0s, however the Wi-Fi radios enjoy some exceptional features.
