Nowadays the need for wireless communication has reached the field of the vehicles as well, for which the recently released IEEE 802.11p standard aims to provide a reliable communication channel. The previous communication standards were not useful between vehicles, because either the appropriate delay couldn't be ensured (GSM) or the coverage was not adequate (previous WiFi standards).
Communication between vehicles is indispensable in order to automate the vehicles later as well as to upgrade the outdated information equipments of the present, and to increase traffic safety.
The main goal of the thesis is to create a test system that is implemented by the 802.11p standard and to make measurements in this new system. First, I present the members of the 802.11 family in detail and a compare their features. Afterwards, the equimpments that are commercially available and support the 802.11p standard will be introduced. Moreover, the publically available results of previous studies and measurements will be mentioned.
After the documentation of information that was needed to carry out the measurements, the results of my own measurements will be shown in great detail. The measurements were conducted in a real environment, where the wireless transmission capacity was observed along with the usable range, the delay, and how these depend on external interference (traffic of cars, buses and trams). Thanks to the characteristics of 802.11p it outperformed the other family members of the 802.11 family in every situation. This statement indeed justifies the application of the new standard in inter-vehicle communication.
