HFS: Buzz Aldrin!

Thu, 17 Jun 2010 06:26:15 -0700

NASA won a Webby Award, which second-man-on-the-moon Buzz Aldrin accepted on their behalf. I love their approach: no more that five words. You've got to choose your words carefully, as Buzz did: "Humanity. Colonization. Phobos. Monolith. Mars!"

And Jake from CollegeHumor.com's "Jake and Amir," who changed his speech when he realized who he was standing next to offstage: "Holy f*cking sh*t, Buzz Aldrin!"

I think space is cool again, thanks to the general public's curiosity and fascination with space. Let's not forget the "we could use the money elsewhere" critics, as they've got a valid point.

Then there's the British metal band Iron Maiden, who opened a new tour in Texas. Yeah, they paid a visit to Johnson Space Center and got to play with the Space Shuttle Simulator.

Coke Mentos Rocket Car

Mon, 07 Jun 2010 09:30:32 -0700

The guys at EepyBird.com are at it again. This time it's a car powered by Coke Zero and Mentos. The video was seen 2 million time in its first week.

Wired went behind the scenes for this story...

Fritz Grobe and Stephen Voltz are the guys behind the famous video of a Mentos-and-Diet Coke, Bellagio-style fountain, which they estimate has been seen by more than 120 million people. Four years later, they’re back with a rocket car powered by nothing but Mentos and Coke Zero. The video, which debuted this week, shows the duo’s efforts to set a land-speed and distance record for a vehicle powered by nothing but erupting, minty, fizzy soda.

The video was directed by Rob Cohen (director of The Fast and the Furious). Two dimensions not enough? There’s even a 3-D rocket car video you can watch on YouTube, if you have a pair of red-and-cyan 3-D glasses.

Wired sat down with Grobe and Voltz shortly after a recent performance at Maker Faire to find out how they built their 900-pound vehicle. It contains 108 2-liter bottles of Coke Zero, 648 Mentos, an elaborate-looking system of PVC pipes and pistons, and a complicated rig for dropping all those mint candies into all those bottles at the same time. In this exclusive Wired.com video, the duo explain how they made the magic happen.

2,400 Jobs for Florida's Space Coast

Fri, 16 Apr 2010 07:29:22 -0700

President Obama is committed to NASA's mission -- and I especially like the promise of employment in and around The Cape.

I'm puzzled by the apparent disagreement among the first moon walkers, Neil Armstrong and Buzz Aldrin.

First, the letter signed by Armstrong, Lovell and Cernan...

The United States entered into the challenge of space exploration under President Eisenhower’s first term, however, it was the Soviet Union who excelled in those early years. Under the bold vision of Presidents Kennedy, Johnson, and Nixon, and with the overwhelming approval of the American people, we rapidly closed the gap in the final third; of the 20th century, and became the world leader in space exploration.

America’s space accomplishments earned the respect and admiration of the world. Science probes were unlocking the secrets of the cosmos; space technology was providing instantaneous world wide communication; orbital sentinels were helping man understand the vagaries of nature. Above all else, the people around the world were inspired by the human exploration of space and the expanding of man’s frontier. It suggested that what had been thought to be impossible was now within reach. Students were inspired to prepare themselves to be a part of this new age. No government program in modern history has been so effective in motivating the young to do 'what has never been done before.'

World leadership in space was not achieved easily. In the first half century of the space age, our country made a significant financial investment, thousands of Americans dedicated themselves to the effort, and some gave their lives to achieve the dream of a nation. In the latter part of the first half century of the space age, Americans and their international partners focused primarily on exploiting the near frontiers of space with the Space Shuttle and the International Space Station.

As a result of the tragic loss of the Space Shuttle Columbia in 2003, it was concluded that our space policy required a new strategic vision. Extensive studies and analysis led to this new mandate: meet our existing commitments, return to our exploration roots, return to the moon, and prepare to venture further outward to the asteroids and to Mars. The program was named 'Constellation'. In the ensuing years, this plan was endorsed by two Presidents of different parties and approved by both Democratic and Republican congresses.

The Columbia Accident Board had given NASA a number of recommendations fundamental to the Constellation architecture which were duly incorporated. The Ares rocket family was patterned after the Von Braun Modular concept so essential to the success of the Saturn 1B and the Saturn 5. A number of components in the Ares 1 rocket would become the foundation of the very large heavy lift Ares V, thus reducing the total development costs substantially. After the Ares 1 becomes operational, the only major new components necessary for the Ares V would be the larger propellant tanks to support the heavy lift requirements.

The design and the production of the flight components and infrastructure to implement this vision was well underway. Detailed planning of all the major sectors of the program had begun. Enthusiasm within NASA and throughout the country was very high.

When President Obama recently released his budget for NASA, he proposed a slight increase in total funding, substantial research and technology development, an extension of the International Space Station operation until 2020, long range planning for a new but undefined heavy lift rocket and significant funding for the development of commercial access to low earth orbit.

Although some of these proposals have merit, the accompanying decision to cancel the Constellation program, its Ares 1 and Ares V rockets, and the Orion spacecraft, is devastating.

America’s only path to low Earth orbit and the International Space Station will now be subject to an agreement with Russia to purchase space on their Soyuz (at a price of over 50 million dollars per seat with significant increases expected in the near future) until we have the capacity to provide transportation for ourselves. The availability of a commercial transport to orbit as envisioned in the President’s proposal cannot be predicted with any certainty, but is likely to take substantially longer and be more expensive than we would hope.

It appears that we will have wasted our current ten plus billion dollar investment in Constellation and, equally importantly., we will have lost the many years required to recreate the equivalent of what we will have discarded.

For The United States, the leading space faring nation for nearly half a century, to be without carriage to low Earth orbit and with no human exploration capability to go beyond Earth orbit for an indeterminate time into the future, destines our nation to become one of second or even third rate stature. While the President's plan envisages humans traveling away from Earth and perhaps toward Mars at some time in the future, the lack of developed rockets and spacecraft will assure that ability will not be available for many years.

Without the skill and experience that actual spacecraft operation provides, the USA is far too likely to be on a long downhill slide to mediocrity. America must decide if it wishes to remain a leader in space. If it does, we should institute a program which will give us the very best chance of achieving that goal.

And here's Buzz Aldrin's piece in USA TODAY...

Since the release of President Obama's NASA budget for the next fiscal year, the debate over America's future course in space has become unusually heated, resulting in a polarization of views that has divided Congress and many members of the space community. All want what is best for our nation, but few see a chance at a consensus that can bring us all together.
We'll get that chance today.

The president will visit the Kennedy Space Center to air these views in a conference on America's future in space. This meeting offers the administration, Congress and the American people our best — and possibly our only — chance to reach such a consensus. This is a reasonable way forward that builds on the president's budget proposal while extending our reach ever deeper into space.

As I have said before, I agree broadly with the president's plan because it contains many elements that I have advocated for years. These include a flexible path for exploration with a robust technology development program enabling the extension of the human presence to Mars. His plan avoids rerunning the moon race that America won 40 years ago and opens a new era for commercial space transportation after years of government dominance of access to low-Earth orbit.

We need specifics

These are good principles, to be sure. But the budget lacks key details. First, I think that the president needs to be clear that Mars is the ultimate goal. The stepping stones to the Red Planet might include missions such as flybys of comets, approaches to near-Earth objects, and finally a manned mission to the Martian moon Phobos. This flexible path would create the infrastructure and transportation systems that would enable commercial and international development near Earth.

NASA also should be clearer about the purpose behind investments in technology. For example, we can utilize the investments made in the Orion spacecraft to jump-start the development of a human deep-space exploration capability. And using the spare hardware left over from the assembly of the International Space Station, I propose we develop a prototype deep-space exploration vehicle that can be docked to and tested at the station.

Over time, astronauts at the station could then outfit the ship, making it capable of forays beyond low-Earth orbit, around the moon, then deeper into space — to near-Earth orbit crossing asteroids, and on to Mars. I also encourage the president to set a clear goal to develop the heavy lift capability needed for our journey to Mars. There are, in effect, placeholders for these programs in the $19 billion devoted to NASA in the president's budget, but I think we deserve a greater level of clarity.

Restore America's place

While transitioning the operation of crew delivery to private industry, it is important that the system we develop is capable of enabling broader commercial markets. To do this, the future plan should include the development of a reusable, space plane-like runway lander as the next generation of crew carrying space transport.

Other astronauts might have different views, and I respect them, but I believe that working with this president toward a consensus on how America can lead human exploration, commercialize that effort in a timely way as possible, and set our collective sites on Mars is more likely to create the kind of sustained effort, commitment and legacy that we all want to see. This seems more productive than simply opposing a change of course.

I also differ with the president's plan in a few critical ways, one being that we should keep the space shuttle in flight while we develop a heavy-lift launch vehicle. This should be a national priority. These investments will give us a solid basis for the civil space program for decades to come.

These additions offer us the chance at a middle ground that preserves our highly specialized workforce, maintains critical access to space, and will enable us to maintain and service the International Space Station. Most important, we can re-establish American space leadership by reaching for this manned mission to Mars.

America's future in space is worth the modest, additional investment that will be required by this flexible path. I hope that, as passions cool, we can all come together at this important meeting to bring our nation fully into a 21st century space program, one that is, as my friend Norm Augustine put it, "worthy of a great nation."

OK, both agree on leadership in space. Especially Mars and deep space, and we can't get there without a heavy-lift launcher. Manned space flight -- and commercial space -- need more heavy-lift rocket development and manufacturing.

As The X-Band Sees It

Sat, 20 Mar 2010 19:32:55 -0700

What the International Space Station looks like in the X-band, via The Planetary Society...

On March 13, 2008, the International Space Station (ISS) passed across the field of view of Germany's remote sensing satellite, TerraSAR-X, at a distance of 195 kilometers.

In contrast to optical cameras, radar does not "see" surfaces. Instead, it is much more sensitive to the edges and corners which bounce back the microwave signal it transmits. Unless they are directly facing the radar spacecraft, smooth surfaces such as those on the ISS solar and radiator panels, do not reflect a strong signal to the detector, so they appear dark. Yet the bright spots outlining edges and corners clearly show the shape of the ISS. The central element on the ISS, to which all the modules are docked, has a grid structure that presents a multiplicity of reflecting surfaces to the radar beam, making it readily identifiable. This image has a resolution of about one meter.

More Spectrum, Please

Tue, 05 Jan 2010 11:22:12 -0800

In an Ex Parte Submission yesterday, the Justice Department is asking the FCC to allocate more spectrum for wireless broadband:

Reallocating spectrum that is being underutilized would encourage the deployment of wireless services and could help to make such services more competitive with wireline offerings. First, an increase in the amount of spectrum that firms could devote to broadband would lower the cost of providing wireless broadband services and encourage entry. Second, more spectrum would allow providers to increase the capacity and reliability of their offerings, thereby bringing them closer to cable modem and fiber-based broadband. Third, the increased capacity in the systems would help support new applications. We urge the Commission to give priority to making more spectrum available to wireless broadband providers so as to maximize their potential to compete against the established wireline ones. According to the FCC Broadband Status Report, there is no time to spare, given the exploding demand for broadband mobile use, the long lags historically experienced in allocating spectrum to new uses, and the danger that "the spectrum pipeline is drying up."

We're all for it here. Good luck in getting the DoD to surrender some of its spectrum. We have a better chance is getting of that "white space" made available by the digital transition by broadcasters.

The DoJ is correct in citing direct-broadcast satellite's introduction as bringing true competition to the video marketplace, and making more spectrum available to wireless broadband services will likely have the same effect.

Here Come the Judge

Mon, 14 Dec 2009 08:29:12 -0800

Judge says no to SES, via Space News...

The U.S. bankruptcy court handling the sale of satellite operator ProtoStar Ltd.’s assets on Dec. 10 rejected a proposed deal between ProtoStar and prospective buyer SES, clearing the way for a wide-open Dec. 16 auction of the in-orbit ProtoStar 2 telecommunications satellite. SES is likely to confront at least one other serious bidder at the auction — Asiasat of Hong Kong — and may also face a bid from satellite fleet operator Intelsat, industry officials said. The Delaware Bankruptcy Court refused to accept ProtoStar’s proposed arrangement with SES under which SES agreed, in advance of the auction, to pay $185 million in cash for ProtoStar 2 on condition that it receive $6.3 million in compensation in the event it was outbid. That meant SES was assured of taking ownership of ProtoStar 2 unless another bidder was willing to pay more than $191.3 million for the satellite. Industry officials said the decision means ProtoStar 2 ultimately could sell for less than $185 million, depending on how badly Asiasat wants the spacecraft, a Boeing 601HP model launched in May and stationed at 107.7 degrees east longitude in geostationary orbit. It carries 27 Ku-band transponders and 13 S-band transponders. The S-band capacity is leased to Indostar and Indovision of Indonesia. SES and Asiasat both have orbital slots nearby and could move ProtoStar 2 to these positions without losing the Indonesian S-band business. Washington- and Bermuda-based Intelsat does not have an active orbital position in the neighborhood, but its representatives nonetheless have been active in the ProtoStar 2 preauction proceedings and attended the Dec. 10 hearing as well, according to bankruptcy court records of the meeting. Aside from SES, Asiasat and Intelsat, no other satellite operators or prospective buyers appeared at the court hearing, according to the list of attendees. Officials from all three companies declined Dec. 11 to discuss their strategies for ProtoStar 2. Intelsat won the ProtoStar 1 satellite at auction in late October, paying $210 million in cash. Intelsat plans to move the satellite, now called Intelsat 25, to 31.5 degrees west, where its C-band payload will provide communications links between Africa and the United States. The Ku-band payload will be used for a beam over West Africa, according to Intelsat.

DIY Friday: Recycle Your Old TV

Fri, 22 May 2009 16:44:52 -0700

On trash days, there seem to be lots of old TVs at the curb. Then, on cardboard recycling days, plenty of boxes from big LCD and Plasma TVs. Kind of makes sense to me.

Hey, instead of just throwing them out, think about recycling/repurposing them. Take, for instance, this working fish tank inside an old floor model...

Here's a "top ten ways to recycle an old TV," courtesy of TopTenReviews.com:

1. Recycle- Televisions can contain lead, mercury, cadmium and other dangerous materials and if disposed of improperly these materials will leak into the soil. This may seem like an obvious option but many people don’t even know that television recycling exists. Even if you decide to keep the TV and just remove its guts look for a proper way to recycle the insides. Most major retailers and manufactures are working to increase television recycling awareness. Go to Earth 911 or Plug-in to eCycling for recycling locations and more information.

2. Donate- Schools especially could use the extra TV love. Most schools have televisions in class rooms on closed circuits or use them to show movies and National Geographic specials. Old TVs will still work with DVD players and VCRs.

3. Give it to the Kids- How many times can you stand to watch Disney DVDs? Put the old set in the kids’ room and let them watch their favorite DVDs and you can have a few moments of peace and quiet.

4. Make an Aquarium- You know you’ve always wanted to make your television into a fish tank. Now is your chance.

5. Use it as an End Table- Those with really old sets that have large wooden enclosures know exactly what this means.

6. Make Art- If people made toilets into art, who’s to say that an old television set can’t be made into art? Use your imagination people.

7. Build a Coffee Table- Turn your television on its back, stabilize, place a piece of glass over top and voila´ you have a coffee table. Hey, you could even hook up a DVD player and have movies play or picture slide shows.

8. Build a Tesla Coil- Take extreme caution if attempting this task. As a matter of fact, forget we ever suggested building a Tesla Coil. They are dangerous and this should only be attempted by professionals.

9. Build a Video Game Machine- For those that like to combine construction and technology you can build an old arcade type console and hook up an old Nintendo or Sega. Pac-Man rules!

10. Make a Planter- Yeah, that’s right, carefully gut the television and make a fun flower planter.

Personally, I like HackedGadgets.com's Top 5, such as this wave vessel:

Retrieving Sputnik

Tue, 07 Apr 2009 18:49:01 -0700

Cool, via Fox News:

In 1970, Marshall Kaplan, then an aerospace engineering professor at Penn State, had a peculiar dream — he wanted to retrieve Sputnik, the world's first orbiting satellite, from space.

Sputnik had been launched by the Russians in 1957, and by 1970 it was no longer operational. Kaplan wanted to go get it.

NASA had never considered space retrieval before, but it thought it was a good idea. Kaplan got the job, but it didn't work out — because the time frame was too short. Sputnik, nearing the end of its life cycle, was already about to deorbit — the technical term for what happens when an object circling the Earth gets close enough to be caught in gravity and burned to cinders in the atmosphere.

But that didn't mean Kaplan needed a new line of work.

In fact, his work was just beginning.

Have you ever seen the Sputnik launch from 1957? Here's the footage:

Live Via WiMAX

Thu, 30 Oct 2008 21:40:06 -0700

Atop Snow King mountain in Idaho, sits a new radio tower providing Internet access using new WiMAX technology. But it can do more than that.

KIFI-TV announced back in May a pioneering way of electronic news gathering that doesn't use microwave or satellite to get the live feed back to the studio:

KIFI News Group calls it WiNG or Wireless Internet News Gathering. KIFI News Group General Manager, Mark Danielson, says, "The WiNG project is based on using the Internet to send content (video and sound) from the scene of a news event back to the station for LIVE broadcast on its television stations and web sites. Danielson says, “The breakthrough is the ability for KIFI field crews to send near Broadcast Quality LIVE shots over wireless Internet."
Danielson says, "WiNG allows KIFI News Group the capability to bring its customers breaking news and information from locations that have never been accessible to routine live news gathering. What KIFI News Group has developed with DigitalBridge Communications has the potential to revolutionize news gathering.” As WiMAX is deployed across the country, Danielson says he expects ordinary news vehicles to turn into fleets of Wireless Internet News Gathering vehicles – allowing for more aggressive coverage of late breaking news and weather events. Danielson says, “In the end, consumers will win as their hunger for breaking news and weather is satisfied by faster access to breaking news from aggressive media companies like his.”

TVNewsday filed this report earlier today on how this could truly be the new scheme for live reports, especially for stations on a tight budget:

Pioneering work on adapting WiMAX for ENG is now underway at KIFI, News-Press & Gazette's ABC affiliate in Idaho Falls, Idaho.
And so far the fourth-generation wireless broadband access service is showing a lot of promise.
"This opens up a whole new world," says Mark Danielson, general manager of the KIFI News Group, who has dubbed its system Wireless Internet News Gathering or, simply, WING.
Unlike so-called third-generation, high-speed mobile technologies like EVDO, WiMAX can provide enough upstream bandwidth for live video.
It's not the best, but it is "definitely acceptable," says Danielson. "Most viewers probably couldn't tell you we're doing anything different."
Danielson can tell you about the difference in cost. Satellite is out of the question for the nation's 163rd largest market. Outfitting a microwave truck costs about $200,000.
But KIFI spent just $12,000 to equip a Toyota Highlander SUV with the necessary hardware and software to send video via WiMAX.
"Plus, I don't have to have any receive sites," Danielson says. "I just have to be in a place where WiMAX exists with Digital Bridge."
Digital Bridge Communications is the local WiMAX service provider, with which KIFI has been closely working. Its BridgeMaxx service covers much of the same ground as KIFI: Idaho Falls, Pocatello, Twin Falls, Rexburg and a number of towns in Sun Valley.
"This is a unique product that was developed for them," says Doug Smith, Digital Bridge's CIO. "This was a first for both of us and one of the first, if not the first, instances of doing broadcast over WiMAX in the U.S. that I'm aware of."
Broadcasters elsewhere may soon be able to experiment with live video via WiMax.
Using spectrum mostly in the 2.5 GHz band, WiMAX is just getting started in the United States, and it is expected to pop up in markets across the country over the next few years.
The big player is (or will be) Clearwire Corp., a planned joint venture that will include some of the biggest names in telecom and high tech: Sprint Nextel, Comcast, Time Warner Cable, Bright House, Google and Intel.
Sprint Nextel, which will own 51 percent of the venture, is folding in its Xohm WiMax unit, which launched a commercial service in Baltimore just last month.
If it all comes together, Clearwire expects to roll out WiMAX service in markets covering about 140 million people by 2010.
But what works in one place may not work in another.
In Idaho, KIFI and Digital Bridge worked out a "special priority service" that guarantees KIFI 2 Mbps upstream throughput when needed for a live shot.
A guaranteed upload speed of 2 Mbps is unusual for broadband wireless service providers. Typically, they offer such speeds only for downloads and much slower upstream bit rates for keystrokes, e-mail and occasional peer-to-peer traffic.
A news operation, of course, works the other way. It needs only small swaths of downstream bandwidth and huge chunks for sending video back to the studio.
Cutting a deal for the fat upstream pipe may not be possible everywhere.
As the service becomes popular, it will be more difficult for a station to set up the sort of sweetheart deal that KIFI has with Digital Bridge. Even in Idaho Falls, the priority service is only available for regularly scheduled newscasts.
"My verbal agreement with them is around news time," said Danielson. "We're learning that their peak time also happens to be around 4 in the afternoon. It's become complicated for them, but they've been able to deliver."
A wireless service provider could be forced to choose between the larger group of customers — some of whom are corporate and paying huge fees — and a steady paycheck from a news operation.
Raycom Media, the station group based in Montgomery, Ala., is intrigued by the KIFI experiment.
David Folsom, vice president-CTO at Raycom Media, says he will probably give it a try in Lubbock, Texas, the only Raycom market where WiMAX is going to be available. A company called Xanadoo is building a system there using licensed 2.5 GHz spectrum.
"The biggest hang-up at the moment is that nobody has created the glue yet for it," says Folsom. "You have a modem and a laptop and a camera but that doesn't necessarily make a remote facility. You need all the parts and pieces."
Nobody knows that better than KIFI, which had to assemble its system form parts and pieces.
Key pieces come from Steambox, a Seattle-based company that specializes to pushing video over IP networks. It's supplying the software that runs on a laptop and encodes and compresses the video for WiMAX transmission as well as the decoder that receives and processes the signal for broadcast back at the station.
"It really became a three-way partnership between us, Digital Bridge and Streambox constantly modifying and make this technology work," says Danielson. "There really are no blueprints for doing what we're doing yet."
"We'll see long term whether the QoS [quality of service] holds up," says Folsom. "The people in the field are not IT people; they're reporters. The issue is the human interface part and we're working on that right now."
Danielson maintains that using WiMAX is not that tough, even for the non-technical types.
"They have a camera, a BridgeMAXX modem, a converter box ... and a laptop computer with the Streambox encoder software. You look at the truck and go, ‘That's it?' There's nothing to it. It's simple. There's no 40-foot mast to worry about."
Aside from the quality of the signal, Danielson's biggest worry is latency of about three interminable seconds in the talk-back between the studio and the remote site.
"We compensate by cueing the reporter about a second-and-a-half before the anchor is done talking," Danielson says. "As far as having audio and video in sync, we have not had any of those issues."
In any event, Danielson and Folsom agree that WiMAX is a step up from EVDO, a widely available wireless access service that has been adopted by many broadcasters for sending video, but only when satellite and microwave isn't possible.
Folsom says he doesn't depend on EVDO for live shots. "We use it for those circumstances in which there's no other way we can do it because we're out of our normal microwave footprint or there's some other overriding reason like the weather.
"I don't suggest for a minute that EVDO is competing with WiMAX at all, but since WiMAX's footprint is so tiny right now and EVDO is everywhere, we're using Verizon EVDO+ and it's been fairly decent for us," says Folsom. "I don't have a lot of complaints."
While EVDO is improving, Danielson won't go that way again. EVDO can't promise bandwidth, he says, noting that an upstream throughput of 1 Mbps is considered a stretch.
At least for the present, KIFI sees WiMAX as a complement to microwave, not as a substitute.
"We still rely heavily on microwave for our primary system. The only downside with microwave is it's line-of-sight to your receive towers," he says.
Eastern Idaho is mountainous so there are many spots that are out of microwave range of the station. That's where WiMAX can help. "BridgeMAXX is more like cellular technology where any place you're within a radius of a WiMAX tower you have the ability to send," says Tory Willmer, KIFI's IT manager.
That Eastern Idaho is also sparsely populated helps, Danielson adds.
Even though its spectrum is licensed, WiMAX, like any radio service, is susceptible to interference, he says. So the more remote the place, the less the chance of interference.
WiMAX is one of two fourth-generation mobile wireless technologies. LTE, or Long Term Evolution, is coming on the heels of EVDO and other third generation services and, while still several years away, promises a more ubiquitous coverage and faster upstream service.
But WiMAX is here now.
"It's a great application for broadcast," says Danielseon. "I predict this is going to be the way things are done in the future. You could have a fleet of WING vehicles with WiMAX at a fraction of the cost of a couple satellite trucks or live trucks."

FCC to Open White Space Spectrum

Thu, 16 Oct 2008 10:57:57 -0700

Daily Wireless has the news that is sure to please advocates such as Google, Microsoft, and Motorola:

FCC Chairman Kevin Martin said today that he will support allowing conditional unlicensed use of the so-called “white spaces” television spectrum. During a press conference, Martin said that he was proposing to let carriers and other vendors deploy devices in white space spectrum which operates unlicensed at powers of 100 milliwatts.
His proposal would also permit use of white space on channels adjacent to existing television stations at powers of up to 40 milliwatts. The FCC is planning to officially vote on whether to allow unlicensed white space use during its Nov. 4 meeting pdf..
Martin said portable devices must have sensing technologies as well as a geo-location database. This would make sure the devices would be able to detect nearby broadcasts in order to avoid those frequencies.
Companies such as Google that are part of the Wireless Innovation Alliance are asking for the white spaces to be unlicensed and open to all.

Here's a video from the Washington Post on testing mobile devices that use the white space spectrum:

So what exactly is white space?

White space in telecommunications refers to unused frequencies in the radio waves portion of the electromagnetic spectrum.

National and international bodies assign differing frequencies for specific uses, and in some cases license the rights to these. This frequency allocation process creates a bandplan which in some cases for technical reasons assigns white space between used bands to avoid interference. In this case, while the frequencies are unused they have been specifically assigned for a purpose.

In an opinion piece over at TVTechnology, Frank Beacham argues that white space is an incredibly valuable public resource that could provide wireless broadband access for as little as $10 a month:

Vacant space in TV Channels 5-51 is perfectly suited for cheap WiFi and other unlicensed wireless services. Failure to take advantage of this publicly owned resource would not only be an enormous waste, but eventually allow the spectrum to be tied up for far less noble purposes.

NAB lobbyists would have you believe that the use of wireless devices in these vacant slices of spectrum would cause interference and threaten the transition to terrestrial digital broadcasting. Sports leagues think the devices might cause static on wireless microphones and coaches’ headsets.

Perhaps they are right about the interference, at least at this early stage of the technology. But what doesn’t work now can be made to work. Sensors can detect which frequencies in an area have no usable TV signals and a device’s transmission can be limited to prevent it from interfering with occupied channels....

THE OTHER SIDE

The NAB, [Ben Scott, policy director of FreePress, a nonpartisan group advocating an open, independent media] said, is engaged in “a campaign of misinformation” to persuade Congress and regulators to ignore the huge potential of unused public airwaves. “In some communities, more than three-quarters of these ‘white spaces’ are vacant,” he said. “The social and economic benefits of utilizing these unused airwaves far outweigh the shortsighted fears of the broadcast industry.”

By using “false assumptions and twisted facts,” Scott said, the NAB is attempting to collapse the entire white spaces debate into a single test of prototype devices at the FCC.

Scott, as well as the high-tech companies advocating the unlicensed use of white space, argues that the FCC’s initial tests actually demonstrated the viability of the smart sensing technology to reduce interference. The tests are being used as a bogeyman in the public lobbying campaign.

It is dangerous, Beacham writes, to allow technical obstacles to cloud the big picture—which is setting important policy as to how a valuable public resource is to be used.
