This paper presents an IEEE 802.11p full-stack
prototype implementation to data exchange among vehicles and
between vehicles and the roadway infrastructures. The
prototype architecture is based on FPGAs for Intermediate
Frequency (IF) and base band purposes, using 802.11a based
transceivers for RF interfaces. Power amplifiers were also
addressed, by using commercial and in-house solutions. This
implementation aims to provide technical solutions for
Intelligent Transportation Systems (ITS) field, namely for
tolling and traffic management related services, in order to
promote safety, mobility and driving comfort through the
dynamic and real-time cooperation among vehicles and/or
between vehicles and infrastructures. The performance of the
proposed scheme is tested under realistic urban and suburban
driving conditions. Preliminary results are promising, since
they comply with most of the 802.11p standard requirements.
