Cross one off the list of Google's friends.
Google is appealing to its users for help lobbying the FCC for approval to use the spaces between television channels as a way to provide wide-reaching wireless Internet service. While the plan could lead to Net access for people who didn't have it before, it also could mean interference with signals.Google is appealing to its users for help lobbying the FCC for approval to use the spaces between television channels as a way to provide wide-reaching wireless Internet service.

Wireless audio-equipment manufacturers and producers of live events are up in arms against Google's efforts to open up a little-used patch of radio spectrum.
What's being contested is the so-called "white space" spectrum, the vacant bands between ultra-high frequency television channels. As U.S. broadcasters transition from analog to digital transmission in time to meet the February 2009 deadline imposed by the Federal Communications Commission, the unused spectrum has become a battleground, pitting not just audio professionals but organizations such as the National Football League, movie studios and Broadway producers against Google.
Google turned up the heat Monday by launching a "Free the Airwaves" campaign with a website and a petition lobbying the FCC to open up the spectrum.
"Remember that fuzzy static between channels on the old TVs?" says the site. "Today more than three-quarters of those radio airwaves, or 'white space' spectrum, are completely unused. This vast public resource could offer a revolution in wireless services of all kinds, including universal wireless Internet."
But for audio-equipment manufacturers and live sound producers, the fuzzy static is their meal ticket.
"We are worried the FCC will buckle and allow white space to be used by personal portable devices seeking wireless services," says Karl Winkler, director of business development for Lectrosonics, a manufacturer of wireless professional audio systems.
The result, say audio industry professionals, could be disastrous. Wireless audio equipment could face significant interference from personal devices searching for wireless connectivity on the spectrum already being used by high-end audio equipment.
"The radio frequency environment is going to become more crowded and more difficult to use," says Mike Torlone, director of marketing services at AKG Acoustics, a division of audio-equipment manufacturer Harman International.
That could potentially lead to loss of signal and interruptions in transmissions, and could force audio producers and production managers to change the way they do business, say experts.
"In that case the number of wireless microphones used will be reduced significantly and it cost big productions millions of dollars to redesign what they do," says Winkler.
The kinds of performances affected aren't limited to the next Justin Timberlake concert or a video shoot for American Idol. While Broadway productions and live shows at Las Vegas are expected to bear the brunt of the decision to open up white space, even local bands, fast-food restaurants, political rallies and church pastors delivering their Sunday sermons could find themselves facing more than a few glitches.
The efforts to unlock the white space has been one of the biggest issues facing the audio-equipment industry and the professionals involved in it, says Bill Evans, editor of trade publication Front of House.
"Everybody is not only angry and upset, they are very, very worried," he says. "We are talking about the livelihood of people here."
The move from analog to digital TV transmission allowed the Federal Communications Commission to reclaim a part of the spectrum, between 698 MHz to 806 MHz. Recently the FCC successfully auctioned the 700 MHz spectrum, a large chunk of which was won by Verizon Wireless.
While a portion of the remaining spectrum has been reserved for future public-safety networks, white space between TV channels remains, and that has caught the attention of companies such as Google, Motorola, Microsoft and Philips.
The tech giants are lobbying to use the white space to deploy new wireless technologies to deliver broadband internet services to portable devices.
That's where the hitch lies, says Chris Lyons, manager of technical and educational communications at Shure, a professional audio-equipment manufacturer.
Lyons says it's not the broadband access per se that will cause problems, but the way devices would have to search through the spectrum for free bands.
Audio professionals claim that prototypes of devices capable of spectrum-sensing have failed some key tests. The FCC is expected to release a final report about the results next month.
For its part, Google says it doesn't want devices that could interfere with wireless audio equipment in the market either.
"From the beginning we have said that no white space device should come to market unless the FCC signs off on it," says Dan Martin, a Google spokesman.
Industry professionals hope there will be a technological fix for the problem soon, one that could allow wireless audio equipment to co-exist with devices using wireless broadband on the same spectrum.
But till then, the FCC needs to stay strong, says FOH magazine's Evans. "We are not ready yet," he says. "We need more time."
Google says it has suggested the use of a geolocation database that would ensure no white space device could transmit without first getting the all-clear from the database. That would allow manufacturers to prevent the use of white space bands in the vicinity of a Vegas show, for instance.
Meanwhile, companies are preparing for the worst. For instance, Lectrosonics is now offering a wider range of frequencies for its wireless microphones.
Until last year, the company's wireless microphones spanned a range of 537 MHz to 768 MHz. Now that a part of that band has been auctioned off, the company has reworked its devices to operate in the 470 MHz to 691 MHz spectrum. It has also added another band, the 944 MHz to 952 MHz spectrum, to the mix.
Those changes haven’t been easy. Over the course of a year, Lectrosonics reallocated engineering resources and spent "several thousand dollars" getting each new product certified by the FCC.
"We have a limited amount of engineering resources and there are hard costs such as FCC licenses that we have had to get," says Winkler.
Smaller wireless audio-equipment manufacturers may not have a choice, says Winkler. "We think a number of manufacturers will be shaken out. Lower quality, lower power systems will have a difficult time."
