America has plenty of wireless spectrum – we just need a new way to allocate it

[Commentary] Recently there has been considerable discussion about a looming spectrum shortage. Yet the reality is that most of our spectrum is unused most of the time. This is because spectrum is managed by often assigning exclusive rights to a particular “licensee” to use a specific frequency in a specific location, and often only for a very specific purpose or service.

This approach, which is analogous to building a private road for every different type of vehicle, leads to inefficient utilization of our nation’s spectrum resources, and impedes the introduction of new technologies. A large percentage of these frequencies service the thousands of government systems that provide the essential functions for our national security. And, in most cases, even if it were possible to reallocate their spectrum for new commercial uses and technologies, the process of doing so is extremely expensive and incredibly slow, taking on the order of a decade or more – far too slow to keep up with our fast-paced digital economy. For these reasons, the President’s Council of Advisors on Science and Technology (PCAST) recently recommended a new approach to federal spectrum management. With a new approach, we can transform the availability of a precious national resource – spectrum – from scarcity to abundance, and do so rapidly. It is time to start building the first shared-use spectrum superhighways.
