Radio-frequency spectrum acquisition and coordination for North American intelligent transportation systems (ITS)

This paper discusses the spectrum acquisition activities that are underway in North America and the spectrum management activities that are occurring in the regulatory agencies that affect intelligent transportation system (ITS) spectrum acquisition. It includes a discussion of the specific spectrum requirements needed to support the 29 User Services that have been adopted by FHWA and ITS AMERICA, and outlines a strategy for meeting those needs through a balanced approach that includes maximum use of existing communications networks as well as the acquisition of new spectrum for critical safety, warning and control functions.
