FCC Action Threatens GPS Satellite Services

The FCC is at it again - this time its International Bureau is considering allowing operation of an interference-generating wireless broadband network from a company called LightSquared smack dab in GPS spectrum used by military, government, and civilian air traffic control, industry, and many American consumers for location, tracking, timing, mapping, surveying, agri-farming, or other GPS satellite-based services in the U.S.  

By all reports and tests made to-date, LightSquared's plan will render GPS unusable in most parts of the nation.

If you or your organization use or depend upon GPS, you are urged to visit the Coalition to Save Our GPS  web site to learn more about this very serious threat.

Tweet the FCC on Twitter

To stimulate public dialogue over the development of a National Broadband Plan, (GN Docket 09-51) the Federal Communications Commission (FCC) has initiated a new blog called "Blogband." The blog will chronicle the development of the broadband plan and invites comments from its readers.

Take a look here: http://blog.broadband.gov/

And, the Commission also has joined the Twitter revolution:

http://www.twitter.com/fccdotgov

Nice to see the folks on the 8th floor at the Portals finally making an effort - albeit a somewhat radical one - to reach out to America (and the rest of the world as well), particularly in view of the way former Chairman Martin communicated with the public.

I'm sure the "new" FCC will get much more "dialog" and "stimulation" than they may be expecting from these initiatives once the general public discovers them (there are already over 10,000 responses to the Broadband Plan on the FCC's ECFS site). There's no doubt that both of these new sites will be ones to keep your eye on.

Spectrum Policy in the Age of Broadband: Issues for Congress

A little light reading from the Congressional Research Service (CRC) for those at all interested in or even a bit concerned about the future of the RF spectrum from a policy standpoint.....

Spectrum Policy in the Age of Broadband: Issues for Congress

Summary

The convergence of wireless telecommunications technology and Internet protocols is fostering new generations of mobile technologies. This transformation has created new demands for advanced communications infrastructure and radio frequency spectrum capacity that can support high-speed, content-rich uses. Furthermore, a number of services, in addition to consumer and business communications, rely at least in part on wireless links to broadband backbones. Wireless technologies support public safety communications, sensors, medicine and public health, intelligent transportation systems, electrical utility smart grids, and many other vital communications.

Existing policies for allocating and assigning spectrum rights may not be sufficient to meet the future needs of wireless broadband and national broadband policy. A challenge for Congress is to provide decisive policies in an environment where there are many choices but little consensus. In formulating spectrum policy, mainstream viewpoints generally diverge on whether to give priority to market economics or social goals. Regarding access to spectrum, economic policy looks to harness market forces to allocate spectrum efficiently, with spectrum license auctions as the driver. Social policy favors ensuring wireless access to support a variety of social objectives where economic return is not easily quantified, such as improving education, health services, and public safety. Both approaches can stimulate economic growth and job creation. Choices about the direction of policy, however, can favor some industries over others.

Deciding what weight to give to specific goals and setting priorities to meet those goals pose difficult tasks for federal administrators and regulators and for Congress. Meaningful oversight or legislation may require making choices about what goals will best serve the public interest. Relying on market forces to make those decisions may be the most efficient and effective way to serve the public but, to achieve this, policy makers may need to broaden the concept of what constitutes competition in wireless markets.

This report considers the possibility of modifying spectrum policy: (1) to support national goals for broadband deployment by placing more emphasis on attracting new providers of wireless broadband services; and (2) to accommodate the wireless broadband needs of industries that are considered by many to be the economic drivers of the future, not only communications, but also areas such as energy, health care, transportation, and education.

Among the spectrum policy initiatives that have been proposed in Congress are: allocating more spectrum for unlicensed use; auctioning airwaves currently allocated for federal use; and devising new fees on spectrum use, notably those collected by the Federal Communications Commission (FCC). The FCC’s statutory authority to implement these measures is limited. Substantive modifications in spectrum policy would almost surely require congressional action. The Radio Spectrum Inventory Act introduced in the Senate (S. 649, Senator Kerry) and the similar House introduced Radio Spectrum Inventory Act (H.R. 3125, Representative Waxman) would require an inventory of existing users on prime radio frequencies, a preliminary step in evaluating policy changes. The FCC also has the opportunity to establish a new course for spectrum policy in the preparation of a Congressionally mandated report on broadband policy, due in February 2010.

The Great "White Spaces" Challenge

Google (and its technology partners) are facing the great "white spaces" challenge - the next big spectrum allocation battle - from the politically powerful NAB (National Association of Broadcasters) and others.

On the one hand we have the over-the-air TV broadcasters (who rarely offer much worth the bandwidth it takes to beam it into our living rooms) insisting that the spectrum will "suffer" from the use of unlicensed wi-fi like devices operating near THEIR frequencies.

On the other hand, we have pretty much the rest of the country clamoring - no, make that screaming - for the opportunity to deploy "innovative" wireless communications devices and services, "stimulate" our economy, and make "better use" of nearly the very SAME spectrum - all on an unlicensed basis with little if any regulatory enforcement of that use. (Which, IMHO, is a somewhat worrisome scenario to begin with considering the historical track record over the years of the FCC's ability to "protect" the natural resource we call the RF spectrum, AND, the purported "better use" and "innovation" that the "white spaces" proponents claim they'll make with the resource.)

This spectrum battle should prove VERY interesting to say the least. Let's hope the regulators make the right decision - whatever "right" is deemed to be these days.

Wireless Spectrum Links & Resources

Those concerned or interested in learning more about U.S. spectrum regulation and frequency allocation policies and their impact on radio and wireless communication devices may want to begin paying very close attention to the Notices, actions and decisions made by the FCC's Wireless Telecommunications Bureau (WTB), the Public Safety and Homeland Security Bureau (PSHS), and, their Office of Engineering and Technology (OET). More background information on spectrum policy, including the latest on the 700 MHz proceeding, can be found on the FCC's Spectrum Policy Task Force site. And, there's always the FCC's Daily Digest which provides a brief synopsis of Commission orders, news releases, speeches, public notices and all other FCC documents (with links to the full text of each) that are released each business day.

Finally, this 2006 paper Regulating Spectrum Management: Overview and Trends is intended to provide readers with a broad overview of wireless communications spectrum management concepts and issues, including a review of differences between traditional spectrum management methods and policy and recent innovations and practices due to technology advances. The approach taken is more descriptive than prescriptive, allowing readers to make up their own mind on various perspectives. It's interesting to note that the authors have found that there are no standard solutions that fit every situation.

TV "White Space" Spectrum Debate Simmers

For those following the TV spectrum "white spaces" debate currently simmering on the FCC's back burner, here is a policy backgrounder worth a read from Sascha Meinrath and the New America Foundation:

According to Meinrath, "smart" wireless devices can use the unassigned frequencies between broadcast TV channels to offer wireless broadband and other innovative services. A rulemaking is pending at the FCC (Docket 04-186 - with over 11,000 comments from the public and industry to date) as to whether to permit unlicensed access to this currently wasted spectrum, subject to technical requirements that will protect television reception from interference. Access to the vacant TV channels in each market has been the subject of intense lobbying, yet far too many of the arguments against "white space" devices rely upon misinformation about the technologies and the FCC process that will prevent harmful interference to DTV reception and other incumbent services.

This policy backgrounder offers a summary analysis, and is an effort to help policymakers strike the appropriate balance between protecting existing services from interference while making the benefits of mobile broadband services available and affordable for all consumers. It provides policymakers with:

1. a brief historical background to the current FCC proceedings;
2. a description of White Space Device (WSD) technologies;
3. a “Myths vs. Facts” section addressing the key concerns raised about WSDs;
4. an overview of the public benefits of WSDs; and
5. a concise summary of where we are in the multi-phase process of adopting WSD technologies for consumer use.

The complete document should be reviewed by anyone interested in or concerned about the development of "white space devices" (WSD's), FCC regulation, and technology -- because spectrum matters.

SDR, CR, DSA, & the 700 MHz Public Safety Band

The folks at the SDR Forum have released a new 23 page report addressing "Considerations and Recommendations for Software Defined Radio Technologies for the 700 MHz Public/Private Partnership" (Technology for 700 MHz Spectrum - Report # SDRF-07-R-0024-V1.0.0) just in time for review prior to the upcoming FCC auction.

Here's a summary:

The report describes how software defined radio (SDR) technologies can help achieve the public/private partnership goals of the upcoming U.S. FCC 700 MHz frequency band spectrum auction. This report also covers cognitive radio (CR) and dynamic spectrum access (DSA) technologies as well.

The context for the report is the Second Report and Order (FCC 07-132, released 10 August 2007) which establishes rules governing wireless licenses in the 700 MHz band. The SDR Forum is uniquely positioned to consider the role of these new technologies in the 700 MHz band since its membership includes commercial mobile radio service providers, public safety representatives, technology developers, systems integrators and equipment manufacturers.

The information and recommendations in the report focusus on technology and related policy considerations to (a) prospective bidders and service providers, (b) potential grantees of the Public Safety Broadband License, (c) equipment manufacturers, and (d) regulators.

Emerging SDR & CR technologies, along with DSA (or DSM - Dynamic Spectrum Management) are believed to be the future of wireless communications.

The report is well worth the time to read for those interested or concerned with spectrum matters.

Managing "Open Access", "White Spaces", & Unlicensed Spectrum

There's more than a few issues and challenges open for consideration and debate when it comes to allowing more and more "open access" and license-free use of the radio spectrum as the authors of this 2005 white paper attempt to point out....

"Managing Shared Access to a Spectrum Commons" (Presented at the IEEE DySpan2005 - Baltimore - November 2005 By William Lehr and Jon Crowcroft)

Abstract

The open access, unlicensed or spectrum commons approach to managing shared access to RF spectrum offers many attractive benefits, especially when implemented in conjunction with and as a complement to a regime of market-based, flexible use, tradable licensed spectrum.

However, as a number of critics have pointed out, implementing the unlicensed model poses difficult challenges that have not been well-addressed yet by commons advocates.

A successful spectrum commons will not be unregulated, but it also need not be command & control by another name. This paper seeks to address some of the implementation challenges associated with managing a spectrum commons. We focus on the minimal set of features that we believe a suitable management protocol, etiquette, or framework for a spectrum commons will need to incorporate.

This includes: (1) No transmit only devices; (2) Power restrictions; (3) Common channel signaling; (4) Mechanism for handling congestion and allocating resources among users/uses in times of congestion; (5) Mechanism to support enforcement (e.g., established procedures to verify protocol is in conformance); (6) Mechanism to support reversibility of policy; and (7) Protection for privacy and security.

We explain why each is necessary, examine their implications for current policy, and suggest ways in which they might be implemented. We present a framework that suggests a set of design principles for the protocols that will govern a successful commons management regime. Our design rules lead us to conclude that the appropriate Protocols for a Commons will need to be more liquid than in the past: (1) Market-based instead of C&C; (2) Decentralized/distributed; and, (3) Adaptive and flexible (Anonymous, distributed, decentralized, and locally responsive).


Offered as suggested background reading and insight in light of the big push for these by the TV "white spaces" proponents, the Cognitive Radio/SDR folks, and the Google's, Intel's, and Microsoft's of the new wireless world.

NTIA Phase 2 BPL Report Finally Released - 3 Years Late

Hmmmm.....so the Feds have finally released the long-awaited Phase 2 BPL Report titled "Potential Interference From Broadband Over Power Line (BPL) Systems To Federal Government Radiocommunication Systems at 1.7 - 80 MHz". (That's the military HF, Amateur, and shortwave radio broadcast spectrum for those who might not know.)

How timely. It's only been 3 years since the NTIA's original Phase 1 report which warned of the potential for harmful interference to LICENSED users that very well could (and have) resulted from the deployment of UN-licensed, Part 15 BPL technology in that portion of the spectrum. The Phase 2 BPL report was supposed to have been issued several months later, but was never made public. One excuse offered for the delay was that there were only 2 report writers within the NTIA to author the Phase 2 report; however, in the opinion of many in the know, the completion and release of the report was deliberately withheld for strategic political reasons.

It's interesting to note that during this 3 year gap, the FCC managed to rush/push/shove their BPL Rules through the regulatory system despite the well-presented and documented concerns and objections of many users of this spectrum. (See the Comments and Reply Comments in the FCC's ET Docket 04-37 for more background and insight on this proceeding.)

It's also telling that a recent report from NATO (9 MB file) seems to contradict some of the findings of the Phase 2 BPL report. I wonder how often certain elements of this report have been "revised" or glossed over in the last 3 years in an attempt to soften the impact of this "spectrum polluting" technology and promote the well-intended but mis-guided notion of BPL providing the so-called "3rd pipe" for wireless broadband access in rural areas?

Finally, isn't it odd that the release of the Phase 2 report comes on the same day the the FCC's own Inspector General released a report that claims the FCC did not withhold similar reports that were not entirely favorable to its policy positions? (Why do I have my doubts?)

Me thinks there is something not quite right here, but, as a good friend often says, I could be wrong....

FCC Says No to M2Z

The FCC today finally responded to M2Z Networks' application for authorization to build and provide a free national wireless broadband network (as previously reported here) using 2.1 GHz spectrum - their answer was no.

In my view at least, that is a correct decision. Now, before anyone jumps to any conclusions about why I believe it correct, take the time to read the Commissions Order yourself which may provide some insight and background that you were not aware of....then we can debate the matter!

700 MHz, TV "White Space" Spectrum, the FCC and the Future of Wireless Communications

She's done it again! Susan P. Crawford, that is. In her latest working paper, The Radio and The Internet, she presents a broad overview and historical background (with many footnotes to more in-depth details for those with inquiring minds) of how the natural resource known as the RF spectrum has been allocated and managed (or, as many believe, mis-managed) by the FCC over the last several decades.

But, she also has done an excellent job (the best I've seen, at least) of putting into a pretty balanced context most of the unbalanced rhetoric, hype, and political posturing from all sides of the hotly debated 700 MHz auction rules proceeding that we've all just experienced.

She also reminds the regulators of the pressing need for them to be much more decisive than they have been regarding the definition of the "public interest" aspect of 21st century spectrum and technology matters during the on-going TV "White Spaces" debate which, by the way, will most certainly be the subject of the next big spectrum battle. Stay tuned - it's likely to be just as contentious if not more so than the 700 MHz debate was since it involves unlicensed use of the spectrum.

Here's the abstract of the paper, but the actual paper is a much better read and really deserves a few minutes of your time:

Abstract:

The airwaves offer the potential for contributing to enormous
economic growth if they are used more efficiently for facilitating
high-speed internet access, but recent industry and government
actions have failed to follow this path.

This article evaluates the multi-billion-dollar 700 MHz auction
regime established by the Federal Communications Commission
in August 2007 as a case study in our national approach to this
valuable resource, and argues that the public interest would
best be served by having ubiquitous access to the internet be
the top priority of communications policy.

The article criticizes the nearly exclusive focus of the FCC on the
interests of incumbents and law enforcement, and suggests that
spectrum policy be focused on enabling unlicensed uses of the
airwaves that can assist the nation with online access.

M2Z Networks to Sue FCC

Startup M2Z Networks is upset that the FCC has yet to take action on a 2006 spectrum application and proposal filed by the company so...... it's going to file a lawsuit against the regulatory agency.

M2Z Networks' proposal is (or maybe was) to offer free ad-supported wireless broadband to 95 percent of the U.S. within 10 years, using 20 MHz of spectrum in the 2 GHz band (2155-2175 MHz). The speed of the free tier — 384 kbps down and 128 kbps up - barely qualifies the service as broadband, but might be acceptable to the average sit-in-the-park-and-surf-the-web wi-fi user who has nothing better to do.

In addition, there would be a 3 Mbps 'premium' service available to paying subscribers. The company proposes to lease the spectrum in exchange for it giving the FCC 5 percent of the gross revenues realized from its premium service. Public Safety entities would also have access to the network at no cost other than for the hardware, if I recall correctly.

However, The Wall Street Journal claims that FCC Chairman Kevin Martin has shared a thumbs down opinion on the proposal with the rest of the commissioners. If the WSJ report is accurate, M2Z's legal threat may be pretty much meaningless.

As to the potential for success for this type of free network? Pretty questionable, at least in my opinion; most ad-supported free wi-fi networks have yet to pan out economically and most have discovered - the hard way - the many real-world realities inherent to wireless performance, coverage, and security. Not many have lived up to the promotional hype generated by their proponents nor delivered the user-experience expected. Besides, how much advertising can one take, anyway?


Check out M2Z's web site, then decide for yourself, though.
