HotSpots worldwide

There are over 100,000 Wi-Fi (Wireless Fidelity) HotSpots worldwide,
according to JiWire. And over 400 municipalities (about half in the U.S.) are now in the process of seeking proposals
for or deploying community-wide Wi-Fi HotZones, according to industry analyst
firm visiongain.
Why Wi-Fi? In today’s global, mobile
economy, Internet access has become a necessity—almost like a utility. Which is why Wi-Fi interfaces are now built into most laptop PCs, personal digital assistants (PDAs) and many smartphones. For communities, providing Wi-Fi access encourages economic development and promotes tourism in a variety of venues, including business districts, airports, convention centers, stadiums, shopping malls, marinas, and other public places where residents and visitors gather. And for wireless service providers, Wi-Fi is the best way to compete against cable and digital subscriber line (DSL)
access, as well as to supplement 3G cellular networks with broadband Internet access and voice over IP (VoIP) capabilities.
