FCC Invites Public to Test TV White Spaces Database; Rules on Collection of White Spaces Info Go Into Effect

The FCC today announced the public testing of a new TV White Spaces database system.  Starting on September 19, 2011, the FCC's Office of Engineering and Technology will open a 45-day window to allow the public to try out the TV Band Database developed by one of the potential TV White Spaces database managers.  If approved, the Database will be used by white space devices to find available frequencies and avoid interfering with authorized services and registered facilities.  As we have written about previously (here) the Commission has adopted new rules to allow unlicensed devices to operate in the television spectrum, but such operations must protect incumbent users.  Accordingly, as part of those rules, the Commission has required the development and use of a database, which TV band devices will be required to access periodically in order to determine available frequencies and adjust their operation.  As we discussed here, the Commission has tentatively selected a number of parties to serve as database managers to develop and maintain such TV white spaces databases.  With this upcoming public trial, interested parties will now have a chance to test the database system developed by one such potential database manager.  As part of its authorization process, each interested database manager will be subject to a similar trial period of no less than 45 days.

During this trial period, interested parties are encouraged to test the database, including the basic functionality, including the following elements:  The channel availability calculator; cable headend and broadcast auxiliary receive site registration; and wireless microphone registration.  Starting on Sept. 19th, the TV band database can be accessed here.  The test site will provide a description of the trial, details on use of the system, and a link for feedback.  Following the conclusion of the test, the potential database manager will submit a report to the Commission, which will also be available for public review and comment.  At the end of the process, the FCC will determine whether this particular system complies with the rules and requirements and whether this database manager will be authorized to operate one of the official databases.  In addition to giving feedback to the database manager through the test site, parties can also submit comments directly to the FCC in the open docketed proceeding ET Docket No. 04-186 regarding the TV bands database systems through the FCC's Electronic Comment Filing System.  A full copy of today's Public Notice can be found here

In addition, perhaps coincidentally, today it was announced in the Federal Register that the rules involving the collection of information for these white spaces database have received OMB approval and those data collection rules are now in effect.  So once the first database managers gain FCC approval and bring their databases online, the government has the green light to instruct parties to populate the databases by registering their services and facilities for protection.  

April 5: Deadline to File Waiver Request with the FCC for TV White Spaces Protection

The FCC recently revised its TV “white spaces” rules to facilitate the use of unlicensed communications devices on spectrum originally allocated exclusively for broadcast television.  Although there is still a long way to go before new unlicensed devices are deployed in this spectrum, the recent revision of the rules has triggered an important deadline.  As detailed in our client advisory issued today and available here, cable headends, TV translators, low power television stations, and other Multichannel Video Programming Distributor (MVPD) receive sites that are located outside a broadcast station’s standard protection zone have until April 5, 2011, to file a waiver request seeking interference protection.

Practically speaking, the vast majority of cable headends, TV translators, and MVPD receive sites that rely on the reception of an over-the-air broadcast signal are located well within the broadcast station’s standard protection zone. Thus, the April 5th deadline applies only to those unique cases in which an existing over-the-air receive site is located more than 80 kilometers (49.7 kilometers) beyond the edge of the broadcast station’s protected contour.

As the filing deadline is less than a month away, we encourage potentially affected parties to promptly review their operations. Television broadcasters, who may not themselves operate a facility eligible for a waiver, should consider if there are cable headends, TV translators, or other MVPD receive sites far beyond their contour that might benefit from a waiver request.  In such cases, the broadcaster should coordinate with the operators of those facilities to ensure a timely submission. 

See today's advisory for further details on this upcoming deadline, as well as our earlier postings here and here for more information about the white spaces rules and the forthcoming white spaces database. 

FCC Ready to Tap Returned TV Spectrum with New White Spaces Order

As the media has reported extensively this week (for example here and here) the FCC is poised to tap into the television spectrum to allow the use of that spectrum on an unlicensed basis, potentially leading to a wave of innovative unlicensed devices, including potentially turbo-charged Wi-Fi.  On the tentative agenda released recently for the next open Commission meeting, to be held next Thursday, September 23rd, the Commission has included an item entitled:  "TV White Spaces Second MO&O:  A Second Memorandum Opinion and Order that will create opportunities for investment and innovation in advanced Wi-Fi technologies and a variety of broadband services by finalizing provisions for unlicensed wireless devices to operate in unused parts of TV spectrum." 

As watchers of the TV white spaces issue will recall, the Commission adopted an Order in late 2008 to permit the operation of unlicensed devices in the so-called "TV white spaces", which is the spectrum in the TV band that is not actively occupied by a television station in a particular geographic area.  (An earlier advisory by Davis Wright Tremaine summarizing the Commission's 2008 Order can be found here.)  Following the adoption of that Order, over a dozen parties sought reconsideration of the Commission's decision; those petitions remain pending.  It is not clear whether the proposed Order would be an Order on Reconsideration, but presumably it will address the issues raised by these petitioners.  In addition, the NAB (National Association of Broadcasters) and others filed an appeal in the Court of Appeals for the D.C. Circuit seeking to challenge the FCC's white spaces Order.  That appeal is on hold pending the Commission's resolution of the Petitions for Reconsideration.  Despite the unresolved objections, in late 2009, the FCC moved forward with putting a spectrum management structure in place that would establish a privately maintained database that would permit coordination in order to locate unused spectrum in the TV band in a particular area.  We summarized this step in an earlier blog entry here.  In early 2010, nine parties submitted proposals to be designated TV Band Device Database Managers, but to date the matter remains pending. 

Now, with the announcement of next week's agenda item, it appears that the FCC is ready to move forward aggressively to allow the use of the TV spectrum on an unlicensed basis.  Chairman Genachowski has touted the TV white spaces as a platform for innovation and development.  In particular, it is seen as a way to expand Wi-Fi and extend broadband service, which in turn would take pressure off of existing wireless spectrum.  On the one hand, the use of the TV spectrum on an unlicensed basis is a simple and artful way for the Commission to "return" the spectrum recaptured by the DTV transition to the spectrum pipeline.  Opening the spectrum to unlicensed devices would allow parties to use the frequencies without the need for an FCC auction and would allow for the tapping of returned channels on a piecemeal, market-by-market basis, which avoids the issue of trying to aggregate contiguous television channels for use nationwide.  In contrast to the clearing of TV Channels 52-59 and 60-69, which was mandated by Congress and factored into the DTV transition from the beginning, there is no clear or easy path for clearing more TV channels nationwide barring a radical restructuring of the DTV Table of Allotments, which would undoubtedly be heavily contested by broadcasters in light of the substantial investments made and disruption brought by the recently completed digital transition.  Furthermore, if unlicensed devices are developed and deployed in the TV spectrum to provide Wi-Fi broadband access, this would potentially alleviate some pressure on the wireless carriers and forestall the much-warned-of and oft-debated "spectrum crunch", which is one of the main driving factors in the National Broadband Plan.  

On the other hand, deploying hundreds of thousands if not millions of unlicensed and unaccountable devices into the television spectrum could have a significant impact on the future of Mobile DTV, as well as on the ability for consumers to receive the signals of local TV stations in their homes.  The fact that the Commission is moving quickly and touting the white spaces as a way to release prime spectrum would seem to be a further indication by the Commission that it does not view over-the-air (OTA) TV signals to be as critical as they once were, notwithstanding the fact that Commission bent over backwards to ensure that broadcasters preserved and replicated their former analog OTA service as they were required to spend hundreds of millions converting their stations to digital.  The importance of the OTA TV signal and consumers' reliance on that signal, however, might change rapidly in the near future with a widespread introduction of Mobile DTV, or as folks cut the cable cord and replace cable service with a combination of over-the-air signals and video over the Internet.  In adopting rules and opening the TV spectrum, it will be essential that the Commission ensure that interference protections, frequency coordination efforts, and unlicensed devices all work as anticipated and do not infringe on the reception of over-the-air television signals. 

Regardless of where one stands on the use of the TV white spaces, and whether the FCC is picking winners and losers by advancing particular devices, services, and innovations to the detriment of existing license holders and industries, the issue is moving forward and will present some fascinating issues in the future.  For example, if a video program is broadcast over-the-air on a TV channel by a television station, it is subject to numerous restrictions and regulations, including the prohibition on indecent material, limitations on commercials in children's programming, rules governing political advertising, etc.  However, if a video program is transmitted through the Internet, which is then, in turn, streamed into the home via a vacant television channel, there would be no such restrictions, despite the fact that it is an identical video program that is being delivered via the same television spectrum.  In that scenario, it would be possible to essentially provide a broadcast-like service on a broadcast TV channel but with no broadcast restrictions and with no license.  Previously, when the Commission reallocated portions of the reclaimed television Channels 52 to 69 for commercial wireless services, it required that if the new licensees of the reauctioned 700 MHz spectrum provided "broadcast-type services" then those services would be subject to all of the applicable broadcast rules.  In the hypothetical posed above, however, there would be no new licensee providing a licensed service, but rather an unlicensed Wi-Fi operation permitting access to the Internet via the television spectrum.  And, with the FCC pushing for universal access to broadband, the differences between television and the new media seem to disappear.  What effect this evolution of media and technology has on the foundation of broadcast regulation remains to be seen.

FCC Approves White Spaces Devices in TV Band - While Some Hail a Boon to Wireless Internet, Others Say Not So Fast

At the FCC meeting held on Election Day, the Commission approved the operation of "white spaces" devices in the TV spectrum.  These would be mobile, unlicensed devices that would operate on TV channels that are not used in a particular location.  Many Internet users have hailed the expansion of wireless Internet opportunities that they believe that this decision will bring.  While the FCC promised that these devices would protect television operations and other current uses of the TV Band, many other groups have reacted to the decision far more skeptically.  All in all, we have probably not heard the end of this debate.

The full text of the FCC Order has not yet been released but, from the Public Notice summarizing the action (which came late in the day, after a several hour delay in the start of the FCC meeting), the FCC appears to have made some concessions to the broadcasters who were objecting that the tests of the white spaces devices were not able to adequately sense the presence of television signals in a way that would protect those stations.  So, to protect television signals, the FCC ordered that, in addition to sensing the existence of television signals, the white spaces devices would also have to have geo-location abilities, which would check the location of the device and compare it to a database of television stations and prevent the device from operating on channels that the database shows to be occupied.  Even with this capacity, organizations representing television stations do not believe that this compromise is sufficient to protect those stations.

Broadcasters are particularly concerned with the degree of protection that is to be provided by these devices.  Press reports quote MSTV (an association of television broadcasters) President David Donovan as being particularly concerned with interference that would be caused to television stations operating on channels adjacent to the channel on which the white spaces device would operate, and also expressed concerns about interference to cable boxes and to wireless microphones used by television newsgathering.  The NAB criticized the failure of the Commission to heed Congressional and industry requests to allow comment on the FCC's most recent engineering study on the interference potential of these devices, which was released only a month before the FCC meeting.  Of even more concern to broadcasters was their allegation that the proponents of the white spaces devices ultimate goal was to capture the entire television spectrum for unlicensed wireless devices, relegating TV to being provided by cable or similar subscription delivery systems.  These fears were based on statements made at a conference sponsored by Google and the New America Foundation, organizations backing the white spaces proposals.

 The New America Foundation, on the other hand, claims that broadcasters claims of interference are overstated and incorrect - and are just part of a pattern of the industry trying to block every new technology that could be competitive.  The FCC Commissioners' statements released at the same time as the Public Notice (Martin, Copps,  Adelstein, McDowell, and Tate) also hail the promise of the new technology as a new broadband competitor while claiming that the protections that have been built into the rules will protect broadcasters. 

Even some commentators associated with the broadcast industry have suggested that broadcasters prepare for the coming of this new wireless technology. Mark Ramsey, in his Hear 2.0 blog, urges radio broadcasters to prepare for the coming competition from "wi-fi on steroids" that would be available on these channels.  Jennifer Lane, in her audio4cast blog, while not specifically reacting to this decision but instead to the general availability of wireless Internet options, suggests that radio broadcasters embrace the Internet, introduce their staffs to Internet radio, or otherwise they will be left behind by new digital competition. 

With all the controversy from broadcasters and others concerned about interference and the processes that the Commission followed, the controversy over this decision probably has not ended.  With all of the promises made for the uses of these devices, the supporters of white spaces are also likely to push to implement this ruling as soon as possible.  This may well be one of those issues that the new FCC will have to deal with yet again in the New Year.

Issues on the Post-Transition Use of the Television Spectrum - White Spaces and Distributed Transmission Service (DTS)

With the final transition of television from analog to digital soon upon us, the FCC has scheduled for consideration at its November meeting two items that will address the use of the television spectrum after the transition - one designed to improve television reception, and the other viewed by television broadcasters as a threat to that reception.  The potential positive development is Distributed Transmission Service ("DTS").  The other proposal - which is far more controversial - is the proposal to authorize "white spaces devices" that operate wireless devices within the portion of the spectrum that will still be used by television stations after the transition.

DTS is the proposal that would allow television stations to use more than one transmitter to reach its service area.  Like the use of FM on-channel boosters, a DTS system would permit stations to use multiple transmitters located throughout their service area, each broadcasting on the same channel, but operating at a lower power than the traditional television station which usually operates from a single high-powered transmitter.  The idea is that, in digital, signals distributed from lower power transmitters spread throughout the service area might be less susceptible to signal impediments from terrain and building obstacles than would a single high-power transmitter.  The FCC proposed adoption of this system several years ago with little opposition, but it has languished.  Some have suggested that the experience in Wilmington, where some people who lived far from the center of the market were having over-the-air reception problems, gave new impetus to DTS as one way to provide better service to these more remote areas.

The second proposal, on white spaces, is far more controversial.  We've written about some of the white spaces issues before, and about one FCC study that found interference problems from these devices.  As these devices operate in the TV band on supposedly empty channels, it is important that they be able to detect television operations so that the devices can protect the TV stations from interference.  Now, the FCC has put the issue on its November agenda, after the FCC's Office of Engineering and Technology ("OET") released a second report which some characterize as demonstrating that the white spaces devices could work in the TV spectrum without creating interference to television reception (or to wireless microphones that also operate in the same frequencies).  However, television representatives have opposed the consideration of this issue without opportunity to comment on this OET Report, arguing that the details of the report show potential interference, pointing particularly at data which, they state, suggests that the white spaces devices have particular problems sensing TV stations operating on adjacent channels and thus could cause interference to these stations.

Thus, broadcasters have been lobbying hard to have the Commission put the issue on hold for further study.  One of the most recent developments was a letter from House Energy and Commerce Committee John Dingell to FCC Chairman Martin, asking a series of questions about the FCC's process - asking if the FCC's engineering report was subject to peer review to suggest any shortcomings, whether the FCC considered licensing these devices so that tracking interference concerns could be easier than with unlicensed mobile devices, and asking for the FCC to account for ways in which it regulates other unlicensed devices and interference issues that may occur ("pirate radio" being included in the list of unlicensed operations about which enforcement history is requested - one area where many broadcasters have alleged that the FCC has often been slow to act to stop illegal operations).  Congressman Dingell has requested the answer to his questions by October 31 - before the FCC's scheduled November meeting.

With this October 31 deadline, we'll see whether Halloween brings a treats or a trick for the white spaces proponents. 

FCC Study Deals Blow to Television White Space Advocates

As the digital television transition continues, broadcasters have been concerned about the proposals made by a number of the major computer companies seeking the right to operate low power wireless devices in the spectrum used by television stations – in the so-called "white spaces" between channels. Because of the potential for interference, television obviously don’t operate on every channel in every city. The proposal by the tech companies, about which we wrote here, would allow unlicensed wireless devices to operate at low power within this spectrum, provided that such devices were “smart” enough to detect television signals and to avoid the use of channels that would interfere with these signals. Last week, the FCC’s Office of Engineering and Technology issued a report finding that the prototypes of these devices that had been made available for testing appeared to interfere with television signals. The report did note, however, that this testing should not be viewed as the end of the story on this issue, as further refinements to the devices might be able to eliminate the interference. The FCC has asked for comment on this report. Public comments are due on August 15, with replies on August 30.

The white spaces debate has been a very contentious one. The tech companies who favor it have argued that the efficient use of the television spectrum, and the congestion in other portions of the spectrum used by unlicensed devices, mandate attempts to allow these devices to operate in the television band on the condition that they do not interfere with TV uses. These companies contend that they should be able to create devices that can sense television stations and avoid interference to these stations.

Broadcasters, on the other hand, fear that the these devices will not be able to fully protect television signals. Especially in a DTV world, where a picture is either there or not (it doesn’t just get snowy as does an analog signal suffering from interference), the risk of allowing an interfering device are great. And given the fact that we’re now right in the middle of the digital transition, where there are bound to be issues even without the introduction of a whole new set of potentially interfering devices, it only makes sense to delay these devices for the the near term. Also, as broadcasters are now looking at introducing their own mobile devices reusing the digital television spectrum ( see our post, here), the Commission should not take any action at this time.

This issue has already been the subject of significant Congressional lobbying, as well as many meetings with the officials at the FCC considering the matter. Given the OET report, it would seem that the push to introduce the devices may slow for the near term. But given that the Commission's staff has left the door open to retesting new wireless devices to see if they can perform better than those initially tested, and the nature of the companies driving this proposal, don’t expect it to disappear for long.
