LStelcom Joins the Ranks of Approved Whitespace Database Administrators

And then there were five (or six).

It never rains but what it pours. We went nearly 10 months without any new whitespace database administrators being approved, and now we’ve had the second approval in under a month. The Commission has announced that LStelcom AG has made it over the final hurdle and its system has now been approved for operation.

This brings to six the number of such approvals that have been issued. The others already admitted to the club: Key Bridge Global LLC, Spectrum Bridge, Telcordia Technologies and Google (twice). (Fun factoid: From the fine print of the LStelcom public notice we learn that Telcordia is now referred to as “iconectiv”. We have modified our table below accordingly.)

From our handy table, it looks like the next contestant likely to join the ranks of the approved will be Comsearch. Our guess on that score is based on the facts that: (a) Comsearch wrapped up its testing – i.e., the penultimate step in the approval process – back in June; and (b) none of the other four contenders has even started its testing.

So six down (if you count Google twice), five to go. Check back here for further updates.

Google Makes It to Finish Line In White Space Coordinator Race, Again

Google joins Key Bridge Global LLC, Spectrum Bridge, Telcordia and, um, Google, in the ranks of “approved” database coordinators.

Add one more (sort of) database coordinator to the “approved” list of white space database coordinators. The Commission has announced that Google has made it to the finish line – it's been approved to coordinate unlicensed “TV white space” devices. This is the second time Google has completed the process. As we have previously reported, Google was first approved in May, 2013. But then last June the Commission announced that Google had come back with a “major modification” to its already approved system – so much of a modification that it needed to go through the approval process again. (While that process chugged on, Google used the also-approved Spectrum Bridge system.) Now that modified Google system has been approved.

Google’s latest success has been included in the appropriate box below.

Five down (if you count Google twice), six to go. Check back here for further updates.

Testing Completed For Seventh White Space Database System

Google wraps up trials on its modified system; FCC invites comments

Looks like it’s time to fill yet another white space in on our white space grid. According to the FCC, hot on the heels of Comsearch (which wrapped up its testing just last month), Google has completed the testing of its modified white space database system. With the report of those tests now on file, the Commission is soliciting comments on the report and on Google’s tests generally. Comments are due by August 13, 2014; replies are due by August 19.

As our handy-dandy white space chart indicates, of the 11 database systems proposed thus far, only four have made it through the FCC’s gantlet to achieve approval so far – and it’s been that way since last November. But with the completion of Comsearch’s testing last month and Google II’s now, we may be looking at a couple more approvals in the not too distant future. Check back here for updates.

Sixth White Space Coordinator Completes Tests

Comsearch wraps up tests, FCC invites comments.

The FCC has asked for comment on white space database tests recently conducted by Comsearch.  Comsearch’s test report can be found here.

It’s been about three and a half years since Comsearch (and eight other database administrator wannabes) got the initial nod from the FCC. But things have moved slowly since then. The original group of nine was eventually expanded to ten when Microsoft arrived late to the party, and most recently to 11 when Google tossed in a "major modification" to its previously-approved system. Before any administrator can be finally approved, its proposed system has to be tested, and the test results must be made available for public comment. Only four of the 11 systems have made it all the way through to final approval thus far. One other (LS telcom AG) has finished its testing but still hasn’t gotten the FCC thumbs up.

Our CommLawBlog entry reporting the commencement of Comsearch’s tests may be found here.

Comments on the Comsearch test report are due by July 8, 2014 and reply comments by July 15.

For background on the databases and what they do, see this article.

White Space Database Update: Google v.2 Now in Beta

There’s been some movement on the white space database administrator front – but it’s hard to call it progress. Readers will recall that Google got its database system approved nearly a year ago. But now comes word from the Office of Engineering and Technology that Google has come up with a “new registration system” which is a “major modification” to the Google system previously approved. That means that the new version will have to be run through the same hoops as the original. Accordingly, for a 45-day test period beginning on June 2, 2014, Google’s new system will be available for public trials. Interested folks can give it the once-over, kick the tires, take it for a spin and see if it does what it’s supposed to.

When the test wraps up – on July 17, or maybe later if the FCC decides more testing is called for – we’ll see the usual drill: Google will have to file a report on the test, public comment on the report will be invited and, if everything works out Google’s way, the FCC will eventually re-approve it as a coordinator. If and when that happens, Google’s new system will rejoin the others already approved.

OET’s public notice indicates that Google is currently relying on Spectrum Bridge (another already-approved coordinator) to manage registration of protected entities on Google’s behalf. Google’s new system is intended to “replace [Google’s] use of the Spectrum Bridge procedures”. What precisely has become of Google’s originally approved system is not clear.

Four other candidates have still not reached the testing phase, so check back here for updates.

In keeping with our white space database SOP, we have updated our handy-dandy table charting the progress of each of the would-be administrators by inserting a new row (for “Google Inc. II”) to track the progress of the latest test process:

White Space Database Update: Comsearch System Ready for Testing

 After a three-month period of inactivity, there’s a sign of life on the white space database administrator front. Finally breaking out of the starting blocks, Comsearch’s TV Band Database System is now ready for public testing. According to a public notice from the Office of Engineering and Technology, that system will get a 45-day test run beginning on February 24, 2014, followed by the well-established drill: Comsearch will have to file a report on the test, public comment on the report will be invited and, if everything works out Comsearch’s way, the FCC will eventually approve it as a coordinator. If and when that happens, Comsearch will join the four others already approved. (For those of you may have lost track, those would be Google, Inc., Key Bridge Global LLC, Spectrum Bridge Inc. and Telcordia Technologies.)

Four other candidates have still not reached the testing phase, so check back here for updates.

Fifth "White Space" Coordinator Begins Tests

LS telcom AG seeks to join the two coordinators operating and two others awaiting approval.

TV “white space” devices operate on TV channels that are vacant in a given area. (On a map of frequency usage, these areas show up in white; hence the name.)

These devices must avoid causing interference to active TV stations, certain wireless microphones, and certain TV reception sites. To accomplish this, most are required to consult a complex and changing database that shows where they can safely operate.

The FCC has identified ten administrators for the database, expected to operate competitively. Before receiving FCC approval, each candidate must run a live test of its operations, submit test reports to the FCC, and survive public comment.

We here in the CommLawBlog bunker have covered developments on the white space database coordination front for several years. Most recently, those developments have been somewhat repetitive and our posts were all starting to look the same. We tried to mix things up a bit with poetry (limericks! a haiku!) . . . but soon found the limit to our poetic abilities.

So here’s what we plan to do going forward.

The table below reflects all the would-be database coordinators and all the steps on the way to FCC approval. Each time there is a new development, we will post an updated version of the table. Dates in the table reflect the dates of the FCC public notices relevant to the particular event. Clicking on a date brings up the respective public notice. The date shown in bold face red will always be the most recent event.

White Space Database Update

The FCC requests comment on white space database tests recently conducted by Google, Inc. and Key Bridge Global LLC.

In separate public notices, the FCC has asked for comment on white space database tests recently conducted by Google, Inc. and Key Bridge Global LLC. (The FCC paperwork misidentifies the second company as "Keybridge Global Inc.") Their respective test reports are here and here. Mark your scorecards: once approved, these will be database managers numbers 3 and 4.

Prior CommLawBlog entries on these tests are here and here.

Comments on both tests are due on June 13, 2013 and reply comments in June 20.

For background on the databases and what they do, see this article.

[Blogmeister’s Note: In keeping with the practice we introduced with our last white space database post, we have sought to capture the essence of these recent developments poetically:

An FCC Haiku to the Public

Comments?  We’re all ears.]

Fourth "White Space" Database Coordinator Tees Up Tests

Next up is Key Bridge Global LLC.

Add Key Bridge Global LLC to the list of TV “white space” database coordinators ready for testing. White space systems, we all know, operate in locally vacant TV spectrum; most must consult a database of other users to avoid causing interference. Of the ten FCC-approved coordinators eligible to provide access to the database, Spectrum Bridge, Inc. and Telcordia Technologies, Inc. have successfully completed their tests and are authorized to support white space devices nationwide, while Google and now Key Bridge Global are in the test preparation phase.

We will keep on keeping track.

[Blogmeister’s Note: As much as we here at CommLawBlog enjoy keeping everybody up-to-date on doings at the FCC, there are limits. Since the FCC started implementing its white space database coordination process, we’ve reported on the appointments of nine -- and then a tenth -- database administrators, three test launches, two requests for public comment on test results, and two final approvals. This post marks the fourth test launch. They are all starting to look the same.

We’re happy to keep reporting as we have done but, frankly, the repetition gets a bit tedious. So we offer here an alternative approach: limericks! 

Here are some examples. We encourage our readers to try their hand, too – submit them as comments. (Nothing X-rated, please.) We’ll post them without criticism. Honest.

Key Bridge Global Authorized to Test

Said the FCC Chief Engineer
To Key Bridge: "Do your test, do you hear?
Just prove you comply --
No, there’s no second try.
Get it right, or you’re out on your rear."

Summary of the White Space Coordination Program To Date

The FCC said to the nation:
We’ve settled on this delegation –
Just ten firms – no more –
That will take on the chore
Of inputting white space co’rdination.

Spectrum Bridge, Inc. became number one.
Telcordia’s next in the sun,
And then Google was blessed
With permission to test . . .
But the FCC still wasn’t done.

Next in line: Key Bridge LLC Global
Coordinates fixed and, yes, mobile
Devices that choose
Just what spectrum to use
And with no interference – that’s no bull.

The Commission has clearly mandated
That each of the firms designated
Will assure straightaway
That white spaces will stay
Non-color co-ordinated.]

Third "White Space" Database Coordinator to Begin Tests

Google is up next; seven more to come.

Unlicensed “white space” devices, which operate in locally vacant TV spectrum, rely on a database of other users to avoid causing interference. The FCC has approved ten coordinators to provide access to the database, and has completed tests on two: Spectrum Bridge, Inc. and Telcordia Technologies, Inc. The FCC subsequently authorized white space operation over much of the eastern United States.

Now the FCC has announced tests of a third provider, a relative unknown called Google Inc. The 45-day public trial will begin on March 4. Details are here. We will let you know the results.

Seven more to go.

FCC Okays Second Area for "White Space" Operations

If you live in Nottoway County, Virginia, you’re in luck.

The FCC has authorized TV white space database coordinator Telcordia to offer service within Nottoway County, Virginia, a mostly rural area toward the southern part of the state. Initial operations will include 20 sites serving rural schools and households. The action comes less than a month after the FCC approved Telcordia’s database, and four months after the first white space operations were approved for Wilmington, NC by coordinator Spectrum Bridge, Inc.

Included in the Nottoway County order are special procedures for registering wireless microphones entitled to protection from white space devices.

We assume the pace of approvals will pick up. At the current rate, we calculate it will take until the year 2797 before white space systems are fully deployed. By then, we expect to be communicating telepathically via devices wired into our nervous systems. Assuming, of course, the FCC can free up enough spectrum.

Second "White Space" Coordinator Approved

Operations are still limited to Wilmington, NC.

The FCC has announced that Telcordia Technologies, one of the ten database managers for “white space” operations, has been approved to provide service to the public. See the details here. Telcordia, which completed its test in January, is the second database manager to secure this approval.   Eight more are waiting in the wings.

But most of the public that Telcordia is authorized to serve will have to wait for that service. For now the FCC has approved white space operations only in Wilmington, NC.

Second "White Space" Database Completes Test

FCC requests public comment on results of Telcordia system testing

“White space” wireless operation on locally vacant TV channels requires that devices consult a database of users entitled to protection, including broadcast TV stations and some wireless microphones. See a list here. The FCC has authorized ten companies to provide and operate those databases. The second such company, Telcordia Technologies Inc., recently completed a 45-day test that began in December.

The FCC now seeks public input on the Telcordia results, which are posted here. Comments are due on February 16, 2012, and reply comments on February 23.

In the meantime, white space operations were scheduled to begin last week in Wilmington, NC, using a database provided by Telcordia’s competitor, Spectrum Bridge, the first to complete testing.

There are still eight database providers to go. We will keep track so you don’t have to.

FCC Approves First "White Space" Operations

First white space database and end-user devices to begin operation in January in Wilmington, NC.

The FCC has approved the first “white space” database and the first end-user devices to begin operation on January 26, 2012, initially limited to the Wilmington, NC area.

White space devices are supposed to provide Wi-Fi-like services, only better, using locally vacant TV channels. Successful operation will depend on complex databases to help each device identify channels on which it can safely operate, without causing interference to TV stations, radio astronomy, wireless microphones, and several other services entitled to protection. We reported just last month that the first of ten FCC-approved database providers, Spectrum Bridge Inc., had posted the results from a 45-day test of its system. The FCC has now announced its acceptance of that system, and simultaneously, its approval of an end-user white space device that operates in conjunction with the Spectrum Bridge database.

Operators of the various services protected against the devices – see a list here – should make sure their facilities are properly listed in the database.

White space operations will be limited at the outset to the environs of Wilmington, NC. Wilmington was also the city chosen by the FCC a few years back for an early trial of the cut-over from analog to digital TV. We’re not sure why the FCC keeps putting Wilmington’s TV reception at risk. Perhaps the city is an unheralded center for high-tech early adopters. Or the home of someone whom the FCC just doesn’t like.

FCC Seeks Comment on "White Space" Database Test

The first of ten database administrators has posted the results of a 45-day test.

We reported back in September about a test of the first database for “white space” devices meant to provide Wi-Fi-like service on unused TV channels. The database – developed by Spectrum Bridge Inc. – is intended to help prevent interference from those devices into TV receivers, wireless microphones, and other authorized users of the bands. The FCC invited public participation in a 45-day online test.

Spectrum Bridge has completed its trials and submitted a “summary report” about it to the Commission. The FCC, in turn, is now requesting public input on the test result and the summary report. The request includes links to the report and three attachments submitted by Spectrum Bridge. We have been unable to access the Spectrum Bridge report and attachments by using the links provided in the FCC’s release. Presumably this is just a slight technical glitch that the FCC will correct.  However, since the Commission’s notice came out just before the start of a three-day weekend, we thought our readers might appreciate some working links to the Spectrum Bridge materials now, to give them something to pore through over the long weekend. Here they are:

The Spectrum Bridge summary report

Attachment 1 – “Dashboard” (statistics concerning traffic to the Spectrum Bridge test site)

Attachment 2 – Registration Records

Attachment 3 – Comments

Attachment 3, in particular, makes for interesting reading. It reflects a number of comments, criticisms and inquiries submitted to Spectrum Bridge during the test, and Spectrum Bridge’s responses. Some of the problems identified in the test are troubling.  For instance, Spectrum Bridge’s database ignored, at least initially, some facilities whose licenses (a) appeared to have expired but (b) were actually still in effect because of pending litigation relative to renewal of the licenses.  But it does appear that Spectrum Bridge was responsive to the problems. We shall see.

Comments on the Spectrum Bridge report are due on November 28, 2011, and reply comments on December 5.

First "White Space" Database Ready for Testing

Anyone can visit the test site to try out the white space channel availability calculator, the wireless microphone registration utility, and other functions.

Those long-promised “white space” devices, delivering super-Wi-Fi performance on locally unused TV channels, are moving a small step closer to reality.

The delay in actual availability – initial rules were adopted almost three years ago – results from the fact that these devices must protect several other services from interference. The main mechanism to achieve that protection is a set of databases that list the locations and frequencies of the services entitled to protection. A white space device is supposed to check in with a database for a safe frequency assignment before transmitting. The first of those databases is now ready for testing.

The services that qualify for protection, and which hence must be listed in the databases, are:

  • broadcast television stations (including full power, TV translator, low power TV, and Class A stations);
  • fixed broadcast auxiliary service links;
  • receive sites (and received channels) of TV translator, low power TV and Class A TV stations and multichannel video programming distributors (MVPDs);
  • private land mobile radio service and commercial mobile radio service operations
  • offshore radio telephone service operations;
  • radio astronomy operations at specific sites; and
  • certain wireless microphone operations.

The FCC has approved ten database administrators to keep track of these services. The idea is for each administrator to set up its own separate database. Each of the ten will extract information on protected services from the FCC’s licensing databases, or from the rules (except for some MVPD and wireless microphone information, which must be entered by hand by interested parties). This information need be entered into only one database, which will automatically share that information with the other nine – so that, as a result, all ten reflect the same protected services. Similarly, no matter which of the ten databases a white space device chooses to consult, it should get back the same information on available channels.

That is the theory, at least. Coordinating ten very large, constantly changing databases, each of a different fundamental design, is likely to present problems in practice.

The first of the ten databases is now ready for a 45-day period of public testing. Beginning on September 19, anyone can visit this site to test the white space channel availability calculator, the cable headend and broadcast auxiliary temporary receive site registration utilities, and the wireless microphone registration utility. Unfortunately the all-important sharing function among databases is not yet ready to try out.

Give it a try, and let us know what you find.
