Labs are a set of carefully chosen, practical and interactive laboratory exercises significantly accelerating the learning process on 4G and 5G wireless technologies. They are primarily targeted at research and educational institutions such as universities and training companies. Labs include predefined laboratory classes guiding the student from fundamental wireless aspects such as radio propagation or OFDM modulation up to more advanced topics such as MIMO and M2M. A wide range of laboratory exercises allows a student to familiarize with both link and network level aspects of 4G/5G systems.
Laboratory exercises are implemented in MATLAB and are based on other 5G Toolset components such as LTE PHY Lab and LTE MAC Lab. Each exercise consists of PDF instruction (including theoretical introduction with references for further reading and tasks for students) and matlab scripts with predefined simulation scenarios, Figure 1. At the end of each exercise, in PDF instruction a student may find exemplary test questions, which can be used to verify the gathered knowledge, Figure 2.

Link and network level exercises
Link-level laboratory exercises are implemented on a basis of LTE PHY Lab and focus on the transmitting and receiving PHY procedures for both eNB and UE. The processing blocks used for the PHY layer exercises are presented in Figure 4.
Network-level laboratory exercises are implemented on a basis of LTE MAC Lab and focus on dynamic behavior of Heterogeneous Network, including MAC layer procedures, propagation and mobility models, packet traffic analysis and transmission statistics. When performing system level simulations, the physical layer is abstracted as shown in Figure 5.
