摘要：	This is the third in a sequence of papers that present the factors involved in identifying the radio frequency spectrum required for both current and future DSRC operations. Since the proposed applications, signal characteristics and channel allocation have been evolving over the course of the spectrum requirement analysis these papers have represented the information available at the time of printing.The first paper was titled Spectrum Requirements for Vehicle To Roadside Communications (VRC), dated October 1995, and discussed the basic requirement to have a sufficient number of channels and spectrum available to accommodate all the potential applications of this communications method. The second paper was titled, Updated Spectrum Requirements for Dedicated Short Range Communications formerly Vehicle To Roadside Communications (VRC), dated March 1996, and added more detail on the interference potential between applications and an environmental perspective. This current paper presents more information on applications, additional considerations in channel assignments, a change in potential signal characteristics,more information on channel bandwidth calculations and information on channel reuse distances. The development of the expectations for this communications area has matured sufficiently that this paper presents a firm estimate for DSRC spectrum requirements.
