FCC proposes that unused TV spectrum goes to wireless
Move is supported by Intel, opposed by others

WASHINGTON - The U.S. Federal Communications Commission (FCC) has proposed
that wireless devices and wireless broadband providers be able to operate in
unused bands of broadcast television spectrum.

In a move supported by Intel Corp. and questioned by a broadcasting
association, the FCC on Thursday voted to begin a process of developing
rules for unlicensed wireless devices to operate below 900MHz and in the
3GHz band of the radio-frequency spectrum. The FCC's proposal would require
that those wireless devices not interfere with existing broadcast signals.
To ensure that no interference is caused to TV stations and their viewers,
the FCC proposed to require unlicensed devices to incorporate "smart radio"
features that detect used spectrum.
Devices allowed under the FCC proposal would include wireless networking
cards for computers, wireless connections to printers and keyboards and
wireless headsets and computer connections for cellular and phones. Also
permitted under the FCC proposal would be wireless transmitters used by
wireless broadband providers to deliver service.

Wireless signals using the TV band can travel farther and penetrate
buildings easier than signals in the current bands used by wireless devices,
according to the FCC.

Intel, a maker of wireless-enabled computer processors, praised the FCC's
decision. The proposal is the first step toward making better used of
broadcast TV spectrum as the U.S. and other countries move toward digital
television, said Pat Gelsinger, Intel's chief technical officer.

"For more than half a century, vacant TV channels (which represent some of
the most valuable spectrum available) have been underutilized," Gelsinger
said in a statement. "Releasing this spectrum for unlicensed use will help
foster new technologies, create opportunities for business and bring
exciting new products to consumers."

But the National Association of Broadcasters said the proposal could cause
"unforeseen" interference to broadcast signals seen by millions of U.S.
residents. "Free, over-the-air television provides invaluable news,
information and entertainment to local communities all over America and
serves as a lifeline to citizens in times of crisis," Edward Fritts, the
association's president and chief executive officer, said in a statement.
"We will work with the FCC to ensure that this proposal can be accommodated
while preserving interference-free over-the-air television."

The FCC Notice of Proposed Rulemaking, which could take several months to
finalize, seeks to establish separate interference rules for personal
wireless devices and fixed access transmitters.

The opening up of the TV bands to wireless devices could create an
"explosion" in new business similar to the impact of the Wi-Fi and Bluetooth
standards, said FCC Chairman Michael Powell. The proposal also could bring
more broadband services to rural areas, he said.

"This technology has the potential to provide greater service to the
American public," Powell said in a statement. "It promises to dramatically
increase the availability and quality of wireless Internet connections -- 
the equivalent of doubling the number of lanes on a congested highway."
