Although several other companies have submitted white space devices to the FCC -- we know Philips has one in, and Google's making a lot of noise about new and improved reference designs -- it looks like Microsoft's run of bad luck with the tech continues, with yet another white space transceiver unexpectedly failing during FCC tests last week. There's no word on if the latest unit failed for the same power-related reasons as the previous test devices, but Microsoft's doing a little damage control and saying that the FCC hasn't found any interference with TV signals so far, and that it's easier to pull the plug now and let other, non-MS devices finish out testing. Yeah, we'd say so -- at this point Redmond's bungled attempts to get this stuff working are becoming sort of embarrassing. Google to the rescue?

Details are a bit sparse, but according to CNET, in the wake of this week's non-defeat in the FCC spectrum auctions, Google is planning a press call to publicly discuss its intentions to continue lobbying the FCC to favor the pursuit of white space data transmissions. We know Google's all joined up with Microsoft, Intel, and a number of other triple-a companies in the white space coalition -- which intends to provide dynamic wireless access on shreds and scraps of unused radio spectrum, bringing the world a step closer to the magical land of software defined radios -- but exactly what G will be announcing we won't find out until next week.

At this point all the snazzy new websites and re-focused marketing efforts in the world aren't going to get Google, Microsoft, and the other members of the White Spaces Coalition anywhere if they don't actually demonstrate the broadband-in-between-TV-signals tech in action -- and it looks like that's proving to be harder than expected. For the second time in seven months, a prototype device has failed testing at the hands of the FCC, although this time it wasn't because it was interfering with TV signals -- it just wouldn't stay powered on. Microsoft says the power issue is "unrelated to the technology points we're trying to prove," but as usual, those prickly pears at the NAB aren't being shy about this latest setback, calling it proof that white space broadcasts are "risky technology that has proven to be unworkable." At this point we're honestly torn -- we hate to side with the NAB and we had high hopes for the white spaces concept, but it just doesn't look like it's panning out. Maybe it's time to move on to bigger and better things, eh?

We've always been totally enamored of the idea of white space wireless transmissions -- using gaps in the broadcast spectrum reserved for TV to transmit broadband-speed data -- but the sad reality is that despite backing from heavy hitters like Google and Microsoft, the idea's never really gotten off the ground. Fierce opposition from NAB and non-working devices aside, however, the White Spaces Coalition just isn't ready to give up: it's just launched the more consumer-focused Wireless Innovation Alliance, which, as far as we can tell, is basically the same pitch with a much snazzier website. While we'd love to see a groundswell of consumer support help get this tech off the ground, we'd say that best marketing would be for a working device to make an appearance, no?

It's not often Microsoft and Google are on the same seemingly-losing side of a debate, but things just aren't looking good for the White Space Coalition, the open-airwaves internet access project backed by the two giants, as well as Dell, HP, Intel, and Philips. The once-promising tech was to transmit broadband-speed data in the "white space" between existing television signals, but pretty much failed its initial FCC testing by causing static on nearby channels and hasn't really been heard from since. Well, that's not enough for the feisty suits at the National Association of Broadcasters, which is taking out a series of ads in a campaign against the system, saying that "while our friends at Intel, Google and Microsoft may find system errors, computer glitches and dropped calls tolerable, broadcasters do not." This fight may or may not have legs depending on how the upcoming 700MHz auction goes, but one thing is clear -- the offices of the NAB are clearly not served by Comcast.

Hot on the heels of the "white space device" test flop of 2007 (i.e., last week's news) Microsoft is regrouping and firing back at the FCC's findings, claiming that the initial prototype was "defective," but a new model works correctly. In an attempt to convince US regulators that use of the soon-to-be-abandoned 700MHz spectrum is "safe" for wireless internet services, Microsoft (along with White Space Coalition cohorts such as Google and Intel) is claiming that the technology is sound and can work side by side with its broadcast television neighbors -- and they have proof. As you'll recall, the first round of tests apparently produced "static" on nearby channels -- leading the FCC to send the coalition packing -- but Redmond is claiming that a new study carried out by the airwave-controlling agency yielded positive results. So, what might have been a major wind-out-of-the-sails-moment for the 700MHz-champions is starting to look more like a healthy gust of air.

It's hard not to love the promise of the White Space Coalition, which includes players like Google, Microsoft, Dell, Earthlink, HP, Intel and Philips. Those crazy kids want to bring us wireless internet over the "white space" bandwidth in between TV broadcast channels, and we say let 'em. One little problem though, FCC says the concept doesn't work. The prototype that the Coalition submitted for review was designed to sense existing TV signals and transmit around them, but the FCC found it inconsistent in this aim, and won't be giving its stamp approval to a device that interferes with existing broadcasts. The FCC does say that it's open to looking at the next generation of the technology, since better performance is certainly possible, and the White Space Coalition wasn't too downhearted: the group is "encouraged that FCC engineers did not find fault with our operating parameters and remain confident that unlicensed television spectrum can be used without interference." Between this fledgling technology and that upcoming 700MHz auction, things are really looking up for WiFi-jilted mobile internet users across the States.
