5G networks are upon us and this next-generation of wireless communication is being powered by a new technology known as millimeter wave (mmWave). MmWave and 5G are used almost synonymously, but there are key differences between the two. The mmWave technology is just one part of what future 5G networks will use. It stands for the technology which is a cornerstone of upcoming 5G networks, allowing for faster data speeds, lower latency AR and VR applications, and much higher bandwidth than ever before. Therefore, this doctoral thesis will deal with the design and analysis of advanced communications featuring millimeter waves, which are expected to be deployed in next-generation communication systems. The main task of the doctoral candidate will be therefore to analyze the current situation in this research area and then propose an optimal solution of communication infrastructure with respect to the expected communication scenarios.
