Expansion of Wireless Internet Access

Wireless Internet access will become more and more pervasive. We have WiFi hot spots, then hot zones. But this year, entire cities — including San Francisco and Philadelphia — will be entire urban zones of wireless Internet access. More cities will follow as new technologies make this possible. One technology is called Edge, which uses the next generation of WiFi, called WIMAX. Some of this access will be free; other places you may need to pay a small monthly fee.
