Here’s a list of national domestic priorities, in no particular order: Stimulate the economy, improve health care, offer fast Internet connections to all of our schools, foster development of advanced technology. Oh, and let’s not forget, we’d better do something about the budget deficit.
Now, suppose that there were a way to deal effectively with all of those things at once, without hurting anyone. And suppose that it would make everyone’s smartphone work better, too. (I’ll explain that benefit shortly.)
I know that this sounds like the second coming of voodoo economics, but bear with me. This proposal involves no magical thinking, just good common sense: By simply reallocating the way we use the radio spectrum now devoted to over-the-air television broadcasting, we can create a bonanza for the government, stimulate the economy and advance all of the other goals listed above. Really.
The reason for this golden opportunity may be in your purse or pocket: that smartphone to which you could well be addicted. The iPhone, the BlackBerry and competing devices are already amazing technologies. But precisely because of the nifty features they offer, like the ability to text photos, stream video and provide GPS directions, the radio spectrum is looking as crowded as Times Square on New Year’s Eve. Demand for spectrum is growing rapidly — a trend that will surely continue.
The problem is that the usable radio spectrum is limited and used inefficiently. Think of it as a 100-lane highway with various lanes set aside for particular uses, including AM and FM radio, TV and wireless computer technology. The government — specifically, the Federal Communications Commission (FCC) — is in charge of deciding which devices use which lanes.
Because we can’t create additional spectrum, we must make better use of the existing space. And the target that looks most promising in this regard is the spectrum used for over-the-air television broadcasts.
These frequencies are very attractive on technological grounds. People in the industry refer to them as “beachfront property” because these low-frequency radio waves have desirable properties: They travel long distances and permeate walls.
We have already allocated parts of this spectrum for mobile wireless, and the FCC recently auctioned some other parts for US$19 billion. That has left 49 channels for over-the-air television.
Why is the current use of this spectrum so inefficient?
First, because of the need to prevent interference among all the stations, only 17 percent of it is actually allocated by the FCC for full-power television stations. The so-called white space among stations is used for some limited short-range applications like wireless microphones.
Second, over-the-air broadcasts are becoming obsolete. Already, 91 percent of American households get their television via cable or satellite. So we are using all of this beachfront property to serve a small and shrinking population.
Suppose we put this spectrum up for sale. (The local stations do not “own” this spectrum. They have licenses granted by the FCC.) Although the details of how to conduct this auction are important, they don’t make compelling reading on a Sunday morning. Interested readers should examine a detailed proposal made to the FCC by Thomas Hazlett, a professor at the George Mason University School of Law who was formerly the FCC’s chief economist.
