Um... guess again... every bit of usable spectrum is allocated...
See http://www.jsc.mil/AcqSup/Gen_spec_policy&info.asp , quoting:
A specialized agency of the United Nations (UN), the International Telecommunication Union (ITU), coordinates international standards, regulations, and promotes the efficient use of the spectrum to maximize the potential for telecommunications services worldwide. The ITU has established an international Table of Frequency Allocations that designates specific bands of frequencies for specific uses within different regions of the globe. Each of the 188 member countries is entitled to participate in biannual World Radio Conferences (WRC) to review and revise regulations and standards. Although each country retains its sovereign right to regulate the spectrum differently within its own borders, the ITU Radio Regulations have Treaty status, and Conference results are ratified by Congress. Neighboring countries frequently negotiate special agreements that apply to their common borders, but the ITU regulations generally form the core of the regulations of its member nations, as is the case for the United States.
