The lectures introduce principles and functionalities of mobile networks with special focus on currently deployed technologies and future mobile networks. Furthermore, architecture and fundamental principles of GSM, UMTS, LTE and LTE-A will be explained. Then, selected key technologies for future mobile networks (e.g., 5G) will be explained.
Students must have fundamental knowledge of modulations, coding techniques and multiple access methods for wireless networks. Furthermore, they must understand to components of a communication chain, signal propagation and radio channel characteristics (attenuation, gain, interference, noise) and characteristics of spectrum and signals (mean value, energy, power, correlation, etc.). They also should have fundamental knowledge of individual layers of RM-OSI model.
The students learn principles of different generations of mobile networks and they will be able to solve problems related to network planning and operation.
