Course detail

Mobile Network Communication Systems

FEKT-MPA-KPMAcad. year: 2021/2022

The attention will be focused on the theoretical background of mobile networks i.e., architecture of mobile networks; definition of the communication technologies and mechanisms by 3GPP; the key parts of the LTE (EPS); radio access network (RAN) of the 4G+ mobile networks; protocol stack in the EPS; procedures in the LTE network; voice over LTE; next-generation mobile systems (5G NR). In parallel to the theoretical lectures, the laboratory exercises, using the Network Simulator 3 (NS-3), will take place to verify the theoretical assumptions in the simulation environment.

Aims

The course “Mobile Network Communication Systems” aims to provide up-to-date information related to the currently deployed mobile networks i.e., 4G (LTE) and recently introduced heterogeneous mobile systems known as 5G NR (New Radio). The attention will be focused on the theoretical background of mobile networks i.e., architecture of mobile networks; definition of the communication technologies and mechanisms by 3GPP; the key parts of the LTE (EPS); radio access network (RAN) of the 4G+ mobile networks; protocol stack in the EPS; procedures in the LTE network; voice over LTE; next-generation mobile systems (5G NR). In parallel to the theoretical lectures, the laboratory exercises, using the Network Simulator 3 (NS-3), will take place to verify the theoretical assumptions in the simulation environment.
