Abstract: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.
