Scientific Background: The spectrum is our name for the variety of electromagnetic radiation that exists.

Political Background: In the United States, the Federal Communications Commission (FCC) regulates the radio spectrum.

Technical Consequences: In late 2002, the battle over the future of spectrum is just heating up. I am a proponent of Open Spectrum, which could lead to a global pervasive network.
