Will WiMax replace Wi-Fi and change the way we live?

WASHINGTON — A wireless technology that Sprint Nextel plans to launch within a year makes high-speed and secure Internet access possible from almost anywhere.

Called WiMax, it's the heart of a huge telecommunications industry effort to supplant Wi-Fi, the service that most users rely on for wireless Internet connections at broadband speeds.

If it succeeds, WiMax technology could be as big a change as the mobile phone revolution. An independent technology consulting firm, Boston-based Yankee Group, estimates that 58 million people worldwide will use WiMax by 2012.

Sprint, which invested $5 billion to become the first company to deliver it in the United States, plans to offer WiMax-embedded electronic devices such as laptop computers and digital cameras by 2009 and 2010, said Barry West, the company's chief technology officer.

Unlike Wi-Fi, which relies on free radio frequencies that suffer from interference, WiMax uses a licensed channel of radio spectrum. It provides clearer, stronger and more secure Internet access. The stronger signal travels farther than Wi-Fi, enabling consumers to get beyond the limits of Wi-Fi "hotspots."
