Interesting Op-Ed piece in today's edition of the New York Times.
"We Interrupt This Broadcast
By Jerrold Nadler
Washington
ON Feb. 17, 2009, all broadcast television stations will end their
analog transmissions and shift to digital signals. This is a complex
process that involves spending billions of dollars to build new high
towers and antennas and to subsidize converter boxes for consumers who
don't have digital TVs.
In all this planning and spending on the transition to digital
transmission, however, we have yet to address the question of 'white
spaces.' White spaces are the intervals between television channel
frequencies to ensure that TV reception is not interrupted by other
signals.
The usefulness of these white spaces is about to be compromised by a
proposal before the Federal Communication Commission by some of the
nation's largest technology companies. Microsoft, Google and others
are asking permission to use white spaces - free of charge - for
millions of unregulated and unlicensed devices for personal networking
systems that they would like to sell, including P.D.A.'s, wireless
broadband devices and even toys.
These devices could disrupt the new TV signals that government and
industry have spent so much time and money to promote.
In my district, which includes New York's theater district, performers
use wireless microphones on these 'unused' frequencies, as do news
crews conducting live interviews on the street. Every major sports
franchise relies on these channels for in-game communications and
sideline interviews. And in rural areas, white spaces are often used
for broadband access.
Unlicensed devices, like wireless laptops and remote-controlled toys,
operating in the white spaces will probably cause havoc to TV viewers,
theater goers and sports fans. They could potentially render digital
television sets and the government-subsidized converter boxes
inoperable. Low-income households, the elderly and people living in
multifamily buildings who don't have cable service and rely on antenna
systems could be prevented from watching their favorite programs and
from receiving important emergency information - nationwide, that's 45
million to 60 million people.
Unlicensed-device advocates say not to worry. They say they'll fix the
problem if it arises. But last year, when the F.C.C. tested the
'sensing' mechanism of some of these unlicensed devices, none of them
detected broadcast and wireless signals consistently enough to avoid
interfering with them.
New Yorkers should be especially concerned. A person walking down the
block looking up an address on his new P.D.A. could easily cause a
television set to go blank or silence the wireless microphones worn by
performers in a Broadway musical. At Giants Stadium, a quarterback
could mess up an important play because he didn't hear directions
being given to him by his coach through a wireless mike. And because
these personal devices would be unregistered, there would be no
effective way of recalling them or curtailing their use, much less
assuring that standards were adhered to their manufacture.
Legislation has been introduced in the House that calls for more
research and testing of these devices and creates a timeline for their
approval, giving priority to devices that provide broadband access to
rural areas. Other devices would be considered only after the F.C.C.
thoroughly tests the new digital transmission system.
While we should encourage technical developments, we should urge the
F.C.C. to proceed with caution.
We cannot let these new developments undermine television service or
hurt key sectors of our entertainment industry.
