This work explores possibilities of Car2Car and Car2X communication. It contains survey of system properties, types of transmission messages, etc. It represents architecture of the system and deals with technical expectations and limitations of system. In the light of the fact that this work is created in the time, when development of this system hasn’t finished yet, the work doesn’t contain details which would allow deeper technical view about area of vehicular communication. The work also deals with the possibility of realization of device, communicating with a similar standard. Like the most suitable standard was chosen an IEEE 802.11a. Mobile unit has been realized by single board computer Mini 2440 and communication has been realized by WiFi module OWS451i, which works as AT modem. Mini 2440 and infrastructure server are based on Linux operation system.
