How WiFi works

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 WiFi 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.
