Abstract:

Wi-Fi or Wireless Fidelity enabled computers send and receive data indoors and out; anywhere within the range of a base station. And the best thing of all, it's fast. In fact, it's several times faster than the fastest cable modem connection. It's powerful. Wi-Fi networks use radio technologies called IEEE 802.11b or 802.11a to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, with an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate or with products that contain both bands (dual band), so they can provide real-world performance similar to the basic wired Ethernet networks used in many offices.
