Mobile telecommunication networks have become widespread in the last thirty years, and nowadays life is unimaginable without them. In my thesis, first of all, I present the development of the mobile communications networks so far, then I present the demands set against the new, fifth generation network, which is still under development, by the equipment manufacturers and the standardization bodies. Then systematically I detail the improvements made to the radio interface, and then the improvements made to the core network. I present several competing developments, thus it is certain that not all of these will make it into the finished network. After these, using an use-case chosen by me: a component of the intelligent transport system, the self-driving cars, but still using a fourth generation LTE network, I present the differences between using centralized communication between the cars, or using direct, device to device communication. Using a simple, self-made simulation program I present numerical results on the latency difference caused by the different types of communication. Finally I present a timeline on the expected introduction of these networks.
