If you believe some radio researchers and engineers, within the next couple of years, high-bandwidth, far-reaching wireless Internet signals will soon blanket the nation. Thanks to a decision by the Federal Communications Commission (FCC) last week, megahertz frequency bands that were previously allocated to television broadcasters will be opened to other device manufacturers. The frequency liberation means that future wireless gadgets will be able to blast tens of megabits per second of data over hundreds of kilometers. They will cover previously unreachable parts of the country with Internet signals, enable faster Web browsing on mobile devices, and even make in-car Internet and car-to-car wireless communication more realistic.
The FCC announcement essentially lets wireless take advantage of unused frequencies in between channels used by broadcast television, so-called white spaces. With the FCC decision, however, researchers and companies finally have the opportunity to turn prototypes into products, knowing that the gadgets could hit the market in the next couple of years. Companies including Motorola, Phillips, and Microsoft have all tested prototypes with mixed results and hope to have robust white-space devices soon.
