WASHINGTON - Wireless devices make it possible to look up driving directions and update Facebook on the go.
But as mobile phones get more sophisticated, they transmit more data, and the spectrum of wireless frequencies is finite. Wireless companies fear they’ll run out of room, leading to congested networks. They want bigger slices of airwaves, even if others have to get less.
“Spectrum is the equivalent of our highways,’’ said Christopher Guttman-McCabe, vice president at CTIA-The Wireless Association, a trade group. “That’s how we move traffic.’’
