Wifi, Wireless Local Area Network, 802.11b/g, Wireless Fidelity... call it what you will. It's everywhere and it's an excellent (cheap) way to stay connected. Sure, 3rd Generation mobile radios are rolling out, but without flat rate tariffs, coupled with the limited availability of 3G, WiFi still remains the easiest and most affordable option for a lot of mobile users who require a high speed connection. WiFi itself has inherent limitations, namely, it only has a short range. Without repeaters, an access point might only broadcast a few hundred feet.
