WIFI Technology

Wi-Fi short for “wireless fidelity”—is the commercial name for the 802.11 products that have flooded the corporate wireless local area network (WLAN) market and are becoming rapidly ingrained in our daily lives via public hotspots and digital home networks. It is a trademark of the Wi-Fi Alliance, founded in 1999 as Wireless Ethernet Compatibility Alliance (WECA), comprising more than 300 companies, whose products are certified by the Wi-Fi Alliance, based on the IEEE 802.11 standards (also called Wireless LAN (WLAN) and Wi-Fi). Wi-fi is a wireless technology that uses radio frequency to transmit data through the air.A Wi-Fi enabled device such as a PC game console, mobile phone, MP3 player or PDA can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more interconnected access points called a hotspot can comprise an area as small as a single room with wireless-opaque walls.There are three types of wireless technology, the 802.11b, the 802.11a, and the 802.11g. The first two are more commonly used, compared to the last one. The difference of the first two is that the 802.11a is newer compared to the other and is about five times faster than the 802.11b. The advantage of the 802.11g technology is that it is backwards compatible with both the 802.11a and the 802.11b technology. And this is a big step forward in the wireless networking world.

WIFI gives you an extremely large amount of freedom because you can basically use it from anywhere. From your couch to your local shopping mall, wireless fidelity can always lend a helping hand. Also, WIFI is not restricted to certain groups. No matter who you are, you can use it. And, on top of its convenience, WIFI is fast, reliable, and easy to use. In the corporate enterprise, wireless LANs are usually implemented as the final link between the existing wired network and a group of client computers. This gives these users wireless access to the full resources and services of the corporate network across a building or campus setting.

Wireless Fidelity is important to the wireless LAN world, because it is securely tested to assure operability of equipment of the same frequency band and feature. WIFI is the certification logo given by the WIFI Alliance for equipments that passes the tests for compatibility for IEEE 802.11 standards. The WIFI Alliance organization, is a nonprofit organization that promotes the acceptance of 802.11 wireless technology and they ensures all WIFI certified 802.11 based wireless networking equipments works with all other WIFI certified equipments of the same frequency. The WIFI Alliance works with technical-groups like the IEEE and other companies that are developing new wireless networking equipments.
