Description
Broadcast TV, once vilified by former Federal Communications Commission (FCC) chairman Newton Minnow as a "vast wasteland," can now also be characterized as a vast roadblock--specifically, a roadblock to the rapid expansion of digital wireless broadband technologies that could produce great economic and social benefits for the United States. In a nutshell, TV broadcasters have thus far been reluctant to vacate highly desirable parts of the electromagnetic spectrum that were lent to them by the federal government in the 1930s and 1940s in order to broadcast TV signals over the air. But the broadcasters no longer need this analog spectrum, because most Americans today receive TV signals from cable or satellite. Meanwhile, purveyors of services using new wireless broadband technologies are locked into inefficient parts of the spectrum that are severely hindering their development. These new technologies are capable of delivering data, video, and voice at vastly higher speeds than today's cable or DSL connections and consequently could speed the development of a wealth of new applications that could transform society. They also could help reignite the telecommunications boom of the 1990s and create billions of dollars of value and thousands of new jobs. It is time for Congress and the FCC to take the steps needed to free up suitable parts of the spectrum--starting with the spectrum used to broadcast analog TV signals--to pave the way for the expansion of digital wireless broadband. To understand the issue of spectrum allocation, it is important to understand what spectrum is. Electromagnetic waves all move at the same speed, at least for all purposes relevant to daily life and business activity. They oscillate, however, at varying frequencies. When the FCC sells or gives away spectrum, it actually is granting a license to use certain frequencies, either exclusively or in conjunction with other users.
