Yesterday, AT&T submitted a formal analysis of the V-COMM Test Report that came out in mid-July claiming minimal impact of Channel 51 and E-Block signals on Band 12 and Band 17 devices. As we previously discussed, there are real credibility issues with the testing conducted by V-COMM for the lower 700MHz A Block licensees.
The V-COMM Report concluded, contrary to multiple other tests and analyses, that although Band 12 devices are far more susceptible to interference from Channel 51 and E Block signals than are Band 17 devices, LTE signals are strong enough to overcome the interference. The problem is that the test assumed an LTE signal strength not likely to occur in most real world situations. After a more thorough review and additional testing by 7Layers (a well-regarded, independent testing firm), it is apparent that the conclusions in the V-COMM Report are wrong, and reflect a number of incorrect assumptions, parameters, and methodology.
There is often more than one approach to take when embarking on an interference test program. In the case of interference testing as with Channel 51 and E-Block, it is not enough to test a best or average case scenario which looks for interference where it is not likely to exist and then claims the results prove it doesn’t exist. That’s like looking for snow at the equator and concluding from its absence that snow doesn’t exist. But that is essentially the case with the V-COMM Report. It is much more useful to look at more challenging scenarios that show the presence of interference and prove those scenarios could occur in a real world. That is the approach taken by AT&T and the test labs on which we relied.

Today, our Chairman, CEO and President, Randall Stephenson, unveiled new initiatives around AT&T’s “It Can Wait” campaign, our nationwide effort to educate Americans on the dangers of texting while driving. We’re calling on people across the country to go to www.itcanwait.com to take a pledge and make a lifelong commitment to never text and drive. We hope to get as many people as possible to take the pledge – and encourage others to do the same – by September 19th, for “No Text On Board – Pledge Day”.
U.S. Transportation Secretary Ray LaHood and FCC Chairman Julius Genachowski have been incredible leaders in bringing distracted driving to the forefront, not only in Washington but in schools and homes across the country. On the heels of their joint partnership, we officially launched our “It Can Wait” campaign in March 2010 in an effort to do our part to address this dangerous, and often deadly, national epidemic. It has been a privilege for our company to work closely with Secretary LaHood and Chairman Genachowski, as well as their staffs, over the years. And their support for our distracted driving initiatives has been invaluable. We look forward to continuing to support the Administration’s efforts and to collaborate when possible.

Last Friday, FCC Chairman Julius Genachowski weighed in on the appropriate spectrum policy for the country and got it absolutely correct. The Chairman made clear he still favors clearing spectrum for auction, where appropriate, while we also explore new sharing ideas that have been developed. He correctly noted that it’s not “an either/or choice” – we will likely need to rely on both models to unlock the full value of our nation’s scarce spectrum resources.
We agree and support the FCC’s direction on spectrum policy. The Commission has long led the way in acknowledging the spectrum challenges our nation faces. The National Broadband Plan was the first major policy document to recognize the need to allocate significant new bands for commercial use – and the dire consequences if its goal of an additional 500 MHz of spectrum wasn’t met. The FCC has also demonstrated the will to address barriers to efficient spectrum use, as evidenced in its ongoing efforts to rationalize for mobile broadband use the MSS S-band and the currently under-utilized WCS band.

The President’s Council of Advisors on Science and Technology, or PCAST, recently released a Report on “Realizing the Full Potential of Government-Held Spectrum to Spur Economic Growth.” The recommendations contained in the Report were driven by the fact that mobile data volumes continue to grow at an astounding pace, and that responding to this demand curve is vital to continued U.S. economic growth, competitiveness and technology leadership. On these points, we fully agree – there are few issues as pressing for the telecommunications industry as freeing up additional spectrum resources to meet demand and foster sustained economic growth in the wireless sector.
The Report’s core recommendations, however, have generated significant controversy. The Report found that the new norm for spectrum use should be sharing, not exclusive licensing. While we agree that sharing paradigms should be explored as another option for spectrum management, sharing technologies have been long promised but remain largely unproven. The over-eager pursuit of unlicensed sharing models cannot turn a blind eye on the model proven to deliver investment, innovation, and jobs – exclusive licensing. Industry and government alike must continue with the hard work of clearing and licensing under-utilized government spectrum where feasible.
On that point, we were heartened by statements made by Tom Power, White House Deputy Chief Technology Officer for Telecommunications, in the days following the Report, clarifying that the Administration has not given up on making parts of 1755-1850 MHz, which he called “this most appealing of spectrum,” available for exclusive commercial use. As reported by Communications Daily, Mr. Power noted that NTIA has concluded that there are significant opportunities for clearing in that band within the next five years. We were also happy to hear Mr. Power recommit to the Administration’s goal of reallocating a full 500 MHz of additional spectrum for commercial mobile use.

On Friday, we filed comments with the Federal Communications Commission (FCC) on privacy issues in today’s mobile world. In May, the Commission put out a public notice seeking information on the measures wireless service providers take to protect customers’ information on mobile devices. As the Commission acknowledges, the wireless marketplace today is a far cry from what it was five years ago when the agency last looked into this area.
In addition to wireless service providers, the whole wireless ecosystem has evolved to include device manufacturers, OS and social networking platform providers, search engines and browsers, and application developers – all of whom play critical roles in protecting the privacy and security of consumers’ personal information.
Think about the extraordinary range of services available to consumers on their mobile device these days, including talking on the phone, sending e-mails and text messages, a dizzying array of apps, posting on their favorite social networking site, surfing the Internet to see what their favorite bloggers have to say, tweeting or following their friends’ tweets, watching videos, listening to music, seeing what great restaurants are nearby, getting directions on a map to that new boutique your friend just tweeted on, sharing and storing photos, and much more.
