Dialogue Concerning the Two Chief Guard Band Systems

Posted by | Wireless | No Comments

This post is a parody of “Dialogue Concerning the Two Chief World Systems” written by Galileo Galilei in 1632, which attempted to prove that the earth revolves around the sun (the Copernican system). Although the Copernican system was ultimately proven to be scientifically correct, Galileo was convicted of heresy and his book was placed on the Index of Forbidden Books for more than two hundred years.

Galileo’s book was written as a dialogue between three characters, Salviati, who supported Galileo’s view, Simplicio, who believed the universe revolves around the earth (the Ptolemaic system), and Sagredo, an open-minded person with no established position. In this parody, Salviati supports the use of actual or de facto guard bands between broadcast and mobile services, Simplicio supports the FCC’s competing guard band proposals in the 600 MHz and 700 MHz bands, and Sagredo remains open-minded.

INTERLOCUTORS

Salviati, Sagredo, Simplicio

SALVIATI. We resolved to meet today and discuss the differences in the FCC’s approach to the potential for harmful interference between broadcast and mobile services in the 600 MHz band on the one hand and the lower 700 MHz band on the other. Read More

Development of the 700 MHz Band Plan in the United States

Posted by | International, Wireless | No Comments

At yesterday’s oversight hearing of the Federal Communications Commission (FCC) in the US Senate, Commissioner McDowell said the rules governing the “C Block” in the upper 700 MHz band were responsible for its lack of interoperability. This wasn’t the first time someone has misunderstood what drove the development of the 700 MHz band plan in the US and the 3GPP process that developed LTE standards for the band, and I don’t expect it will be the last.

The 700 MHz band plan is complex and riddled with exceptions based on its unique history. I presented a keynote describing that history and its impact on the band to an international audience at 4G World last year. The keynote explained why the US couldn’t simply adopt the technically more efficient and interoperable “APT” band plan for 700 MHz that is preferred in Asia and was recently adopted by Mexico. The presentation I gave at 4G World is available here: 4G World 700 MHz Keynote.

Consensus at Mobile World Congress 2013: Mobile Internet Era Requires More Spectrum, Capital, and Collaboration

Posted by | International, Wireless | No Comments

A quartet of industry leaders from around the globe provided their perspectives on the mobile Internet during this morning’s opening keynote session at Mobile World Congress in Barcelona: Randall Stephenson, President and CEO, AT&T; Xi Guohua, Chairman, China Mobile; César Alierta, Executive Chairman & CEO, Telefonica; and Vittorio Colao, Chief Executive, Vodafone. The keynote session provided a rare opportunity to see how international mobile operators view the revolutionary changes that are reshaping the mobile industry and our world. The most surprising revelation was the general consensus among this diverse group regarding the opportunities and challenges presented by the mobile Internet.

FCC Incentive Auction: Will the FCC Pick a Winner Among Mobile Technologies?

Posted by | Wireless | 2 Comments

Congress recently mandated that the Federal Communications Commission (FCC) make additional spectrum available through a novel incentive auction designed to transition television broadcast spectrum to mobile use. The FCC’s task is to adequately compensate television broadcasters for relinquishing their spectrum while ensuring such spectrum is rapidly transitioned to mobile uses that benefit consumers nationwide.

SCOTUS Healthcare Decision Indicates FCC Interoperability Mandate Unconstitutional

Posted by | Wireless | No Comments

The Communications Liberty and Innovation Project (CLIP) recently filed comments at the Federal Communications Commission (FCC) opposing an interoperability mandate in the 700 MHz band. CLIP argued that the proposed interoperability mandate would be manifestly unjust. The Supreme Court’s holding in the healthcare opinion issued last week indicates that the mandate could be more than merely unjust: it might be unconstitutional.

CLIP Opposes FCC Technology Mandate in 700 MHz Band

Posted by | Wireless | No Comments

Later today the Communications Liberty and Innovation Project (CLIP) will be filing comments at the FCC opposing a technology mandate in the 700 MHz band after deployment has begun and without industry consensus. Imposing a technology mandate in the 700 MHz band after auctioning the spectrum pursuant to flexible rules would be another step backwards at the FCC. Since the early 1990s, the FCC had been making progress toward a more market-based approach to communications policy. Over the last two years, however, it has looked more like a 1930s-style central planning agency than a 21st century expert. A surprise technology mandate in the 700 MHz band would bring it another step closer to its central planning past.
