Development of a Communication System Following 802.11p and Wave Standards

This paper presents an IEEE 802.11p “full” stack prototype implementation to data exchange among vehicles and between vehicles and the roadside infrastructures. The prototype architecture is based on FPGAs for IF and base band purposes, using 802.11a based transceivers for RF to/from IF conversion. Power amplifiers were also addressed, by using commercial and in house solutions. This implementation aims to provide solutions for tolling or any other related services, problems caused by traffic congestion and a way to prevent or mitigate accidents by establishing a radio communication link among vehicles or between vehicles and infrastructure. The performance of the proposed scheme is tested under realistic urban and suburban driving conditions. Wireless Access in Vehicular Environment (WAVE) refers to a set of emerging standards for mobile wireless radio communications. WAVE or Dedicated Short Range Communications (DSRC) 5.9GHz as is also known in USA, is part of the Federal Highway Authority’s Vehicle Infrastructure Integration (VII) initiative and supports Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications for emerging Intelligent Transportation Systems (ITS). WAVE systems will be used due to low latency and high data rate requirements in a high mobility environment. The WAVE standard is being developed by IEEE to respond at the necessity to solve a common problem of many worldwide cities, vehicular traffic and related e-safety. In Europe the European Commission has also allocated 5.9GHz band for priority road safety applications and inter-vehicle and infrastructure communications. The intention is to ensure the compatibility with IEEE standards even if the band is not exactly the same, but the frequencies will lie close enough apart to enable the use of the same RF components.
