WiFi (Wireless Fidelity)

WiFi stands for Wireless Fidelity. WiFi is a wireless technology like a cell phone. WiFi enabls computers to send and receive data to/from other computers indoors and outdoors, anywhere within the range of an access point. The access point acts as a hub for computers to communicate with each other. WiFi networks use radio technologies called IEEE 802.11b or 802.11a to provide secure, reliable, fast wireless connectivity. While the radius of each access point is normally no more than a fifty metres, it can be extended by using repeaters. The radius could be more than one kilometer if you use more powerful or directional external antennas.
