Wi-fi on steroids

The FCC is set to approve use of unlicensed bandwidth for wireless use. Turns out there's all this room on the spectrum and it can be used to make super powerful wi-fi networks that can cover entire university campuses. Or entire hotels.

The unused bands of spectrum were generated by the conversion of television signals from analog to digital. Because digital transmission uses a smaller slice of spectrum, more "white space" was freed up around each broadcast signal. It is those white spaces that the F.C.C. is now seeking to put to use. The new airwaves are particularly attractive because television signals are low-frequency waves, meaning they can travel farther, go more easily through walls, trees and other obstructions, and provide more reliable connections.
