WiFi

(Wireless Fidelity) is the popular term for the 802.11b wireless Ethernet standard.  Wi-Fi areas, coined to also be known as "hot spots", are generally found in your favorite coffee shops, airports and hotels. Even though WiFi areas sometimes are limited to a smaller radius (typically 100-300 feet indoors and up to 2000 feet outdoors), the speed is significantly faster than using standard EDGE, GPRS, HSDPA or EV-DO cellular access.
