The constant availability and the continous contact are very important for our society, it is hard to imagine the world without being able to reach anyone at any time. The data flow is more data transfer than voice communication nowadays, which requires high data rates and constant availability.

Over the last few years, the Internet of Things (IoT) has gained an increasing role, which has added expectations to the mobile network that are still unavailable today. Among others high data rates, as the amount of information will increase, a minimum delay time that is critical to security critical systems, but these requirements can not be guaranteed by the current 4G mobile network. The 5G mobile system is designed to meet these needs and provide a stable base for their perfect functioning even for under-developed techologies. One of these technologies is Device-to-Device communication, which builds a direct wireless connection, and 5G network is needed for it.

In this paper I introduce this technology, its benefits and weaknesses, and I show some realization options, I simulate the data transfer rates of these constructs and evaluate the results. Finally, I’m going to propose the possibilities of development.
