Vehicular Ad Hoc Networks (VANETs) is an important component within the intelligent transportation systems (ITS) that have been part of global strategy and advanced applications. The aim is to provide innovative services relating to various modes of transportation and traffic management. These systems enable users to reach their destinations better, safer and more coordinated. In order to make the system workable, several radio access technologies (RAT) such as UMTS, WiFi, WiMAX and radio

Furthermore, Inter vehicle communication requires the use of wireless standard which support high data rate along with better communication range in sparse as well as in dense situation. The paper provides study of different wireless standards supported by VANET and compare their parameters (range, data rate, and frequency band). Finally, the survey recommends the best suitable wireless standards for non-safety applications both real time and simulation time environment.
