First 'white space' network hits Claudville, Virginia

by Donald Melanson posted Oct 21st 2009 at 3:41PM

Well, this one's been years in the making (literally), but it looks like the very first white space network using those newly freed up broadcast TV channels has now been lit up in Claudville, Virginia (population 916), which should just be the first of plenty more rural communities to come. As you might expect, the network was no small undertaking even considering the size of the town, and involved an "experimental license" from the FCC, network infrastructure from Spectrum Bridge, and a slew of equipment that Dell, Microsoft and the TDF Foundation contributed to the local school and computer center. No word on anything like actual speeds just yet, but we're guessing the Claudville residents will be plenty pleased regardless, as they've been stuck with nothing more than dial-up or expensive satellite internet until now.

Microsoft still hot for white space, describes WhiteFi wireless tech

by Tim Stevens posted Aug 19th 2009 at 8:11AM

The white space odyssey continues, with manufacturers of all backgrounds and sizes salivating so heavily over the bountiful frequencies opened up by the DTV transition that they're willing to fight the NAB in a corporate cage match of epic proportions. Microsoft, part of the White Spaces Coalition and a company that's not always had success at this whole frequency-sharing thing, isn't giving up yet, presenting a paper this week at ACM SIGCOMM 2009 describing yet more new approaches and algorithms that would allow white space communication that functions like traditional WiFi devices -- but with ranges measured in miles instead of feet. Dubbed WhiteFi, the tech would include algorithms to enable both access points and clients to zero in on the same locally disused frequencies without stepping on the toes of other broadcasters. It certainly sounds like a consumer-friendly implementation, and something we'd very much like to deploy at the 442 acre Engadget compound in northwestern Montana (it's three counties away from the nearest hotspot), but we're not entirely convinced this latest approach will find any more success at appeasing/defeating the NAB than any of the prior attempts.

IEEE begins work on wireless standards for white spaces access

by Darren Murph posted Mar 24th 2009 at 10:55AM

We're probably still months, if not years out from seeing this whole white space debate amount to anything productive, but at least the IEEE is already toiling away on two new standards to address architecture and interfaces for white spaces access. In an admittedly jargon-filled release, the group responsible for keeping 802.11n in draft status for 14 centuries has reportedly approved work to begin on a new duo of protocols for "heterogeneous wireless networks based on the existing IEEE 1900.4 standard." The group specifically mentions IEEE P1900.4a, an amendment to 1900.4 which aims to "examine architecture and interfaces for dynamic spectrum access networks in white space frequency bands." Said standard would basically act to define new components for operating in white space frequencies, and with standardization will hopefully come easier implementation of widespread broadband. Check back in a score or so to see if we've made any progress.

NAB throws down, sues FCC over white space internet

by Nilay Patel posted Mar 4th 2009 at 2:46PM

Look sharp, Julius: you may have thought the debate over white space internet was over since the FCC approved the Google- and Microsoft-backed plan and the industry's gearing up to make it reality, but part of the new gig is learning that nothing's ever over while NAB still has lawyers at its disposal -- the prickly broadcasting organization has filed suit to stop the tech from hitting the market. As usual, NAB says that despite all the convoluted geolocation sensing and interference detection measures the White Spaces Coalition promises to implement, TV signals will be interfered with, and that's not okay. Of course, we've heard all these arguments for years now, and while white space devices have had a rocky test history, they've been successful recently -- it seems like NAB is taking advantage of confusion at the FCC following the delayed DTV transition to try and pull the rug out while no one's looking. A bastard move, to be sure, but we doubt it's going to be successful -- going up against both the government and the heavy hitters of the tech industry is rarely a winning idea.

White Spaces Coalition launches DB Group, letting devices find their own piece of the spectrum

by Tim Stevens posted Feb 5th 2009 at 9:42AM

The white space debate over how (or whether) to utilize unused frequencies in the broadcast spectrum has been going on for nearly two years now, and, despite all the ups and downs (and fear mongering), the various members of the White Spaces Coalition have continued to fight the good fight in the hopes of bringing faster downloads to more places. The latest initiative/olive branch is the formation of the White Spaces Database Group, mapping areas of unused spectrum and enabling devices to verify what frequencies are available based on positional information (likely GPS or cell tower triangulation). It's still early days so there aren't any details about the database itself yet, except that the group intends to keep things "open and non-proprietary" and will work with the FCC to populate it. Now, can't we all just get along and work toward a summer of worry-free wireless?

FCC cancels white space meeting to focus on digital TV transition

by Darren Murph posted Dec 15th 2008 at 12:05AM

Man, we're clearly in the wrong line of work. It seems that being in the FCC means that you can basically ignore everything else going on so long as you squint really hard and pretend to make progress on an imminent event that's just over two months ago. Sure, we're just bitter, but we're struggling to understand why an agency this large can't work towards auctioning a slice of soon-to-be-freed airwaves for widespread internet use while educating consumers on the digital TV transition that's coming in February. Caving to requests from Democratic lawmakers, the FCC has canceled a December 18th meeting that would've been used to discuss the next step in making the most of white spaces, but unless we see these very suits walking the streets with signs saying "THE END IS NEAR! FEBRUARY 17TH, 2009!," we're going to be rather peeved.

Dell affirms plans to integrate white space radios into future wares

by Darren Murph posted Nov 6th 2008 at 8:55AM

Barely 24 hours after the FCC voted yes to unlicensed white space use, we've already got one powerhouse lined up in support. According to PC World, Neeraj Srivastava, director of technology policy at Dell, has stated that the company "intends to integrate white space radios into future Dell products." As for what "products" actually means? We could see the modules in anything from laptops to netbooks to "any other devices that provide wireless network access." Sadly, he wouldn't say when the technology would be added, but we'll go out on a limb and suggest sometime after the impending digital TV transition.

FCC votes yes on unlicensed white space use

by Darren Murph posted Nov 5th 2008 at 4:23AM

You win some, you lose some -- so says FCC chairman Kevin Martin (pictured), in a roundabout way, at least. The hard-fought campaign for using the freed "white spaces" from the upcoming DTV transition in America has at long last led to victory for proponents such as Google, Microsoft and Intel, but suffice it to say, not everyone is thrilled about the decision. Essentially, the approval will allow unlicensed use of the soon-to-be-liberated spectrum, which could pave the way for mobile broadband access in rural locations (for example). Fuming TV broadcasters will theoretically be protected from any unwanted interference, as any device "offered by a technology company for use on the white spaces will have to go through a rigorous certification process." More wireless in '08 -- now isn't that something we can all agree on?

FCC considering delay of white space vote at NAB's request

by Donald Melanson posted Oct 20th 2008 at 7:11PM

In a series of events that's becoming all too reminiscent of the National Association of Broadcasters' attempts to stifle the XM / Sirius merger, the FCC now says that it is considering the NAB's recent last-minute request to delay the forthcoming November 4 vote on authorizing unlicensed white space devices (or WSDs). According to Ars Technica, however, while the FCC is considering the proposal, it's hardly enthused about it, with agency spokesperson Rob Kenny saying that it is "important to note that this proceeding has been open for several years and recently included multiple rounds of testing in the lab and field, which were open to the public and provided all interested parties with ample opportunities to comment and provide input." For its part, the NAB and a consortium of other broadcasters say that the FCC is relying on a "a flawed reading of the OET test results," and that if the vote passses, "WSDs will be let into the broadcast band without the protections that are necessary to prevent widespread interference to television and cable reception." As you might expect, the FCC hasn't yet tipped its hand as to when it might rule on the NAB's request, but if it does get its way, the vote would be delayed 70 days for a public comment cycle, or conceivably longer if the NAB finds another wrench to throw into the works.

Broadcasters seek to slow action on FCC's white space ruling

by Darren Murph posted Oct 18th 2008 at 4:20PM

We knew they didn't like it, and now they're going out of their way to prove it. After FCC chairman Kevin Martin set forth a proposal to use the freed spectrum from the forthcoming 2009 digital TV transition for bringing mobile broadband to more locales, broadcasters who'd rather not deal with the trouble are stepping in with a collective "nuh uh!" Station owners and the four television networks filed an "emergency request" on Friday afternoon in hopes of convincing the FCC to hold off on its plan to vote on white space rules until "everyone had a chance to comment on the findings." The report that's mentioned found that no significant interference would come into play should the waves be opened up for unlicensed devices, but a spokeswoman for the National Association of Broadcasters stated that "the FCC is misinterpreting the actual data collected by their own engineers." Whether or not NAB will get the 45-day grace period it's asking for, however, remains to be seen.

FCC chairman wants to fill white spaces with broadband

by Darren Murph posted Oct 16th 2008 at 4:32AM

Good news, folks -- Kevin Martin believes that more mobile broadband is good for this nation. And we're all about getting the WiFi to the people. Just as expected, the FCC chairman has voiced his support for using vacant airwaves from the looming 2009 digital TV transition to bring mobile broadband to more areas. According to Martin: "No one should ever underestimate the potential that new technologies and innovations may bring to society." His proposal was issued ahead of an official report asserting that potential interference with existing infrastructure could be avoided if "technical safeguards" were put in place to prevent it. Sounds good from here, now go 'head with your bad self, Mr. Martin.

FCC expected to recommend unlicensed white space spectrum use

by Darren Murph posted Oct 12th 2008 at 4:59PM

The back-and-forth between mainstream carriers and external mega-corps may finally be coming to an end, with the almighty FCC expected to make a pivotal determination regarding the use of white space in short order. For those unaware, white space refers to the freed spectrum that will become available when broadcasters move completely to digital TV next February, and there's been a heated debate between carriers (who typically "fear" unwanted interference by unlicensed use) and tech companies like Google who see this as a great opportunity to bring wireless services to rural areas (for instance). According to a new report from Reuters, the FCC is expected to weigh in at any moment, and it'll "likely" recommend the unlicensed use of the spectrum. The advice will be based on reports generated from years of data collection, but we're all stuck waiting in tense anticipation until it's released. Anytime now, FCC...

Wireless audio manufacturers unhappy with Google's whitespace internet plans

by Nilay Patel posted Aug 20th 2008 at 9:40AM

It's never been a secret that pro-level wireless audio manufacturers are nervous about the Wireless Innovation Alliance's whitespace internet plans, but now that Google's taken the fight to the people directly, various equipment makers are starting to air their concerns publicly -- and with millions of dollars in gear and people's livelihoods on the line, they aren't being shy about it. "We are worried the FCC will buckle and allow white space to be used by personal portable devices seeking wireless services," says Letrasonic's Karl Winkler, as professional wireless audio systems like those used in theaters and rock venues exist in the same frequency spectrum and redesigning them to avoid interference could "cost big productions millions of dollars." That's of course the same concern groups like the NAB had about television broadcasts, but where we can see consumers being willing to put up with some TV static to get cheaper net access, we don't think rock bands and stage performers will be as willing to compromise -- and although Motorola says its geolocation system will prevent any interference, it doesn't sound like the industry is ready to buy it. Of course, all these hysterics are based on nothing more than speculation and rumors, since basically no one's ever seen a whitespace device in use -- maybe if one of the giant companies backing the tech would actually demo some of this vapor, people wouldn't be so nervous about it. Just a suggestion -- albeit one we've been making for months now.

Google takes whitespace to the people with "Free the Airwaves"

by Nilay Patel posted Aug 18th 2008 at 10:56PM

Whitespace internet has long had heavyweight industry backing from the likes of Dell, Microsoft, and Motorola, and while those companies and several others have been lobbying Congress and the FCC through staidly named groups like the Wireless Innovation Alliance and the White Space Coalition, it looks like Google is sick of the red tape -- it's launching a petition drive aimed squarely at consumers called "Free the Airwaves." Yep, Google's cribbing its whitespace marketing from Pump Up the Volume -- and while that's certainly enough to convince us, we've got a feeling it's not going to sway anyone else's opinion until this semi-vaporware tech is actually demonstrated working outside of an FCC lab. Put up or shut up, El Goog -- or at least play a Descendents song or two.

Motorola declares white space device testing successful

by Paul Miller posted Aug 8th 2008 at 10:38PM

Motorola is claiming success in the latest round of FCC white space device testing, countering Microsoft's numerous failed attempts. "It worked as well as we said it would," said Motorola's Steve Sharkey. So there. Motorola's device is mostly based on its geolocation capabilities, which in addition to its "sensing" tech allow it to know where which spectrum is being used by digital TV in that particular area and avoid it proactively. Sharkey calls the tech "absolute, solid protection," which should make members of the white space coalition happy -- though we haven't heard positive word from Philips, Adaptrum and InfoComm yet, who were also testing devices alongside Motorola, but aren't using the geolocation technology. That, and the FCC has the final word on all of this, so we'll just have to wait for that word from on high before we start riotous, interference free partying in the streets.
