The V2X technology is a quite complex field in the communication sector. It is required for the automotive industry to further evolve the travel experience and safety, as well as to reduce the environmental impact of vehicles. The chapter reviewed various V2X technologies. Two of the key challenges are interoperability and compatibility. The competing access technologies, i.e. WLAN-based and cellular -based communication, are very different in their whole philosophy. Therefore, it is assumed that both technologies will coexist and spread on their own. There will be no consensus that will favour one over the other. This also means that the communication devices have to support both main access technologies resulting in multi -stack equipment. Of course, this has fmancial consequences as well. To complete this thought, it should be noted that WLAN-based V2X communication has geographical restrictions as well. However, this stands for a vehicle itself and its features as well, thus this issue is less significant.
