Free WiFi offered by google in select airport

Introduction:-

Wi-Fi is a class of wireless local area netwerk. Wi-Fi is the trademark of the Wi-Fi alliance. Google has announced that it is giving all travelers in select airports free WiFi service during the holiday season as a gift to allow them to keep in touch. The free WiFi will be available now through January 15, 2010. Service is available in 47 different airports around the country.

Uses:-

A Wi-Fi enabled device such as a PC, video 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 or as large as many square miles covered by overlapping access points. Wi-Fi technology has served to set up mesh networks, for example, in London. Both architectures can operate in community networks.
