      Google wants TV 'white space' for wi-fi


      Less than a week after losing in the latest U.S. spectrum auction, Google Inc. has started pitching its plan to use TV "white space" — unlicensed and unused airwaves — to provide wireless Internet.

      In a letter to the Federal Communications Commission released by Google on Monday, the Internet search giant pressed the government to open up the white space for unlicensed use in hopes of enabling more widespread, affordable Internet access over the airwaves.

      "As Google has pointed out previously, the vast majority of viable spectrum in this country simply goes unused, or else is grossly underutilized," Richard Whitt, Google's Washington telecom and media lawyer, wrote in the letter. "Unlike other natural resources, there is no benefit to allowing this spectrum to lie fallow."

      Google said the white space, located between channels 2 and 51 on TV sets that aren't hooked up to satellite or cable services, offer a "once-in-a-lifetime opportunity to provide ubiquitous wireless broadband access to all Americans."

      In addition, opening up the spectrum would "enable much-needed competition to the incumbent broadband service providers," Whitt wrote.

      It was not the first time that Google has urged the FCC to open up television white space, but the Internet company's public letter, sent Friday, was notable given Google's involvement in the just-ended 700MHz wireless spectrum auction.

      Google was outbid by Verizon Wireless, but the Internet company had already convinced the FCC to require the winner of a specific portion of the spectrum to allow subscribers to use any compatible wireless device they want.

      Google is also developing mobile phone software, known as Android, that several device makers are using to power their upcoming handsets.

      Google is betting that it can boost its online advertising business by making it easier for mobile consumers to get access to the Internet on their mobile phones.

      TV broadcasters oppose use of white space, fearing such usage would cause interference with television programming and could cause problems with a federally mandated transition from analog to digital broadcasting signals next year. But Google in its letter urged the FCC to adopt a series of overlapping technologies, including "spectrum sensing," designed to prevent signals from interfering with each other.

      Whitt said Google was not advocating any specific business model to develop the white space. He said there was enough unused spectrum for businesses to create a wide range of options, such as building small peer-to-peer networks or even establishing an alternative national wireless carrier.

      Whitt said he did not expect any changes to the status quo until after the United States shifts from analogue broadcasting to digital TV in February 2009. He said consumer devices compatible with white space spectrum could be on the market as early as late 2009.

      Arrow White Spaces Overview

      White Spaces Overview



      In the United States, most wireless microphones are classified by the Federal Communications Commission (FCC) as licensed devices and operate in radio frequency (RF) spectrum that corresponds to locally unused TV channels. As part of the transition to Digital Television (DTV), which ends on February 17, 2009, the FCC has decided to reallocate some of the upper UHF TV spectrum to other services, such as public safety. As a result, the new “core” TV band will consist of TV channels 2-51(up to 698 MHz).



      In addition, the FCC is also studying the possibility of allowing unlicensed devices to use future “unoccupied” TV channels, which policymakers now refer to as the “white spaces“. These unlicensed devices fall into two categories – fixed and portable – and include such items as wireless broadband services, wireless multimedia systems, PDAs, and cordless telephones. Currently, these products operate in other radio frequency bands, such as 2.4 GHz. The FCC’s proposed date for allowing unlicensed devices to operate in the new core TV band is February 17, 2009, in conjunction with completion of the DTV transition.



      Congress and the FCC are under intense pressure from major lobbying groups to allow unlicensed devices to use the TV spectrum. Even though wireless microphones would retain their licensed, secondary use status (secondary only to digital television), the white spaces proposal creates a potential for interference to wireless microphones from unlicensed devices. Shure is concerned about this proposal, and in response has mounted a significant effort to explain the issues to the decision makers with the goal of arriving at a workable means for preventing interference to wireless microphones.



      Shure has filed several rounds of formal comments with the FCC, and in addition, has met with the FCC on a number of occasions to explore ways to prevent interference. The FCC granted Shure a Part 5 experimental license and a special temporary authorization to conduct interference tests using a simulated wireless broadband signal in the TV band. Shure presented the results of these tests to the FCC and gave live demonstrations to U.S. House and Senate staff members. Shure also assembled a coalition of the industry’s preeminent wireless users and providers to communicate their concerns with the white spaces proposal to key legislators and FCC officers.



      Shure is a member of two work groups organized by the Institute of Electrical and Electronic Engineers (IEEE) -- the world’s leading professional association for the advancement of technology. These groups include the 802.18 Radio Regulatory Technical Advisory Group (RR-TAG) and the 802.22 Wireless Regional Area Network (WRAN) group. The WRAN group is developing a standard for unlicensed wireless broadband in the TV spectrum. Shure joined these groups to help represent the interests of incumbent TV spectrum users and to develop a standard that will help prevent interference to wireless microphones.



      Currently, U.S. Senators Kerry and Sununu have drafted legislation that would force the FCC to shorten its timeline for allowing unlicensed devices to operate in the TV bands. The FCC, IEEE, and other industry technology leaders have stated that adequate time must be allowed to develop solutions that will permit unlicensed devices to operate without causing harmful interference to current users of the TV spectrum, including wireless microphones. In the form of comments to the FCC and correspondence with Congressional representatives, support for this position has come from other wireless microphone manufacturers, the broadcast, theater and live sound production community, audio equipment retailers and integrators, houses of worship, and end users at various technical levels.



      Shure encourages all parties interested in the continued successful operation of wireless microphones, personal monitors, intercoms and IFB devices to state their position with decision makers in Washington, D.C. To assist in this effort, please see instructions for filing formal and informal comments with the FCC. Direct written communication to U.S. House and Senate representatives is also encouraged.

      Vacant airwaves spur TV-tech turf battle

      By DIBYA SARKAR,
      AP Business Writer

      Ten months before the nation flips to digital television, technology companies and TV broadcasters are fighting over the virtual remote, with different ideas of what to do with the unused airwaves.

      Google Inc., Microsoft Corp. and others on Tuesday are launching an advertising and lobbying blitz to convince Capitol Hill that these unoccupied airwaves, or "white spaces," could be used for affordable high-speed Internet service, greatly benefiting rural areas and spurring competition and innovation.

      Tech companies say the technology is there to allow low-powered, unlicensed devices, such as cell phones, laptops and BlackBerrys, to operate in the empty spectrum without interfering with over-the-air TV programming and wireless microphone signals.

      The Federal Communications Commission is trying to figure if the technology can do this, although several publicized tests have failed.

      Such stumbles are exhibit A in the case TV broadcasters are making against opening up white spaces. The broadcasters, who've aired their opposition through an equally aggressive lobbying campaign, say if such use is allowed it will interrupt, namely freeze, TV pictures. Viewers could be stuck staring at Paula Abdul's face while this week's winners of "American Idol" are announced.

      Programming disruptions are why broadcasters want white-space access to require a license. They've proposed auctioning off the spectrum for licensed use that could turn the white spaces into a private estate instead of a free public park.

      That's not what lawmakers will be hearing starting Tuesday.

      Over the next several weeks, members of the Wireless Innovation Alliance, will tout white-space benefits to lawmakers, who they say are not getting the full picture because their opponents — namely the National Association of Broadcasters — are playing politics and spreading lies.

      "We want science to play it self out at the FCC. Broadcasters don't. They want politics to mess up science," said alliance spokesman Brian Peters, who's a lobbyist for the tech trade group Information Technology Industry Council.

      When the nation makes the switch to digital TV in February 2009, broadcasters will occupy channels 2 through 51. But almost half those channels in some cities will remain fallow, especially in rural areas where there are fewer broadcasters. Those white spaces are considered valuable because they can travel long distances and go through walls.

      But the white spaces are not completely empty either. Many licensed wireless microphone signals — popular in sports venues, concerts, Broadway theater and even houses of worship — have used them for decades.

      There's "virtually no record" of microphone signals interfering with TV broadcasts, said Mark Brunner, a spokesman for Niles, Ill.-based Shure Inc., one of the country's largest makers of wireless microphones and other audio equipment.

      The microphone industry is singing the same tune as broadcasters: unfettered white space use could harm signals and licensed use may be an answer.

      The tech alliance says technology to detect and avoid broadcast programming and permit broadband transmission is doable and point to the testing of similar equipment by the U.S. military and other countries, such as Great Britain.

      Microsoft, Philips Electronics North America Corp., Adaptrum Inc. and Motorola Inc. have submitted devices to the FCC, which plans to issue a report sometime this summer. But twice this year, Microsoft devices have broken down during tests. Last year, the agency gave another Microsoft device a failing grade.

      Three strikes in the lab, say broadcasters, should keep the devices out of the market.

      "You would not have Google, Microsoft and others engaging in a broad, wide-ranging political lobbying effort if their equipment worked," said David Donovan, president of the Association of Maximum Service Television, the technical arm for the TV broadcasting industry. "They're in trouble."

      Peters says that's false. Lawmakers want something done with the spectrum, he says, as long as it doesn't interfere with programming — a desire shared by his group.

      The FCC is collecting data to write safe-operating rules for unlicensed devices in the spectrum. The devices that have failed are not prototypes for consumer products.

      Google recently suggested additional safeguards from interference, but opponents shot them down.

      Broadcasters and wireless microphone say auctioning the spectrum off — an idea also proposed by the CTIA — The Wireless Association, the telecommunications industry's main lobbying group — would hold a licensee responsible for interference problems and remedies. With unlicensed portable devices tapping in, they say it's virtually impossible to find the source to any interference.

      "Let's see how serious they (technology companies) really are instead of getting a free ride and threatening the digital television transition," said NAB spokesman Dennis Wharton.

      Rep. Fred Upton, R-Mich., last year suggested such an auction although he hasn't formally proposed any legislation.

      Edmond Thomas, a former FCC engineer whose law firm represents tech companies supporting white spaces, said licensing the spectrum makes no sense. He said a single gatekeeper will tightly control access and service and offer devices that won't be as appealing and innovative as in an unlicensed regime.

      "You'll have so many innovators all exploring ways for it be used," he said.
