In the 1960s, David Easton famously defined politics as the authoritative allocation of scarce resources. Today, one of the scarcest resources is radio-frequency spectrum. Modern communications systems?television, radio, cell phones, WIFI?transmit and receive signals using an assigned portion of this invisible domain. If two systems try to use the same ?slice? of spectrum at the same time, interference and weak, inaccurate signals can result.
With the proliferation of high-speed, wireless devices, the demand for radio-frequency spectrum has increased dramatically in recent years. The domain?s regulator, the Federal Communications Commission (FCC), is sometimes forced to choose between conflicting claims and competing visions of the common good. And as a recent controversy surrounding a Virginia-based communications company illustrates, spectrum allocation can be an untidy process?and have implications for both national security and global economic infrastructure.
Fighting for Spectrum
In 2010, LightSquared announced its plans for a new nationwide network for high-speed, mobile communications based on the new 4G standard. Its business model appeared to fit in nicely with President Obama?s June 2010 memo calling for ?unleashing the wireless broadband revolution? by making more spectrum available for wireless broadband use.
LightSquared?s technical solution entailed erecting nearly forty thousand towers across the country that would broadcast in a frequency band immediately adjacent to the one used by the Global Positioning System (GPS). Early on, this raised concerns that the private network's strong transmissions would overpower and degrade the much weaker GPS signals.
While acknowledging these concerns, the FCC granted the company a conditional waiver to proceed with its ground-based network in January 2011?while stipulating that the issue of potential interference with GPS still had to be resolved.
After assessing test results from both LightSquared and multiple government agencies (including the Federal Aviation Administration, NASA and the air force, which develops, launches and operates the GPS satellites), the FCC concluded last month that LightSquared?s proposed network would indeed adversely impact GPS services. Moreover, it saw no practical way to mitigate the potential interference in the short term. Accordingly, the FCC signaled it would not give final approval to build the network.
LightSquared claims that it has already invested more than $4 billion in the project. The fallout from the FCC decision was almost immediate: The company?s CEO resigned. Employees were laid off. Sprint Nextel canceled a key contract. Published reports indicate that LightSquared might declare bankruptcy. And Republican lawmakers have asked to see the documents and cost data associated with the FCC?s review of LightSquared?s original proposal.
A Free Global Utility
As difficult as this latest news has been for the company and its investors, as well as for proponents of expanded access to mobile broadband, approving the use of a system that threatened to interfere with GPS would have been a colossal blunder.
