WI-FI (WIRELESS FIDELITY)

Wi-Fi (Wireless Fidelity) is a wireless networking technology that uses radio waves to provide network connectivity and Internet high speed level.Wi -Fi Alliance, an organization that has Wi-Fi trademark term, specifically defines Wi-Fi as part of the product WLAN (Wireless Local Area Network) based on the standards of the Institute of Electrical and Electronics Engineers (IEEE) 802.11. Wi-Fi is easy it also means the IEEE 802.11x.

Initially, Wi-Fi is used only in the 2.4GHz 802.11b standard, but Wi-Fi Alliance has expanded its use of the term Wi-Fi to any type of network or WLAN products based on 802.11 standards, including 802.11b, 802.11a. dual-band, and others.

Wi-Fi to work without using a physical connection between sender and receiver cables, but with the technology of Radio Frequency (RF), a frequency within the electromagnetic spectrum associated with radio waves. When RF is supplied to an antenna, the electromagnetic, will be made and entered into a corner of a wireless network called an Access Point (AP). The main task is to spread AP (broadcast) wireless signal is detected on the computer and 'entry' into it. To connect to the AP and join the wireless network, computers and devices must be equipped with wireless network adapters.

Wi-Fi is available at: video game consoles, home networks, PDAs, mobile phones, operating systems, and other types of electronic products. Product that has been tested using a Wi-Fi will be labeled Wi-Fi Certified by the Wi-Fi Alliance.
