Detailed topics of the laboratory practices:

1. Mobility support in the Internet Protocol (MCL)
According to the current trends, the most popular services are being implemented over IP. This technology is called All-IP. The widely available IPv4 (IP version 4) systems are unable to serve the increasing amount of demands and ensure the necessary QoS (Quality of Service) parameters; therefore, new systems need to be developed. One of these systems is IPv6, the objective of the practice is the demonstration of the Mobile IPv6 protocol.

2. GeoNetworking protocol (MCL)
The objective of the practice is to introduce students to GeoNetworking protocol and the possibilities it offers. They get acquainted with the IWCU unit, set the configurations necessary for operation, and write and test programs using GeoNetworking communication. The practice demonstrates a common task in engineering: getting to know a previously unknown device and protocol over a limited amount of time.

3. LTE radio interface and simulation (MCL)
The LTE (Long Term Evolution) wireless data transmission standard provides the users a fully IP-based, packet-switched technology. From 2011, its LTE-Advanced version has become well-known as „4G”, and it is one of the mobile solutions projected to be in use for an extended period of time. During the measurement, students get acquainted the main modulation formats used in mobile communications with the help of modern devices, then simulate a fourth-generation data transmission in the LTE Toolbox of MATLAB, analyzing the parameters influencing the channel.

4. TCP over Wireless (MCL)
In the ISO/OSI reference model, the transport layer, located above the network layer, is responsible for ensuring same order delivery, reliable transmission, flow control and congestion avoidance. There are several transport protocols available, from which the most appropriate one is chosen depending on the type of application. The students will learn about the detailed operation of the TCP transport protocol and its different variants, and will examine their performance under different simulated network conditions.

5. Quantum communications laboratory 1 (MCL)
Basics of quantum communication, properties of optical fiber channels. Measurement and analysis of the attenuation, radiation losses and other quality degrading effects in an optical transmission medium. During the practice, the students get to know the basics of optical fiber measurement technology.

6. Quantum communications laboratory 2 (MCL)
Basic phenomena of quantum information, free-space quantum communication. During the measurement, students are introduced to the fundamental phenomena regarding quantum information and quantum informatics, and get to study the basics of free-space quantum communications using experimental setups.

7. MapReduce performance measurements (AddICT)
The objective of the practice is to introduce the MapReduce paradigm in the Apache Hadoop framework (Apache Hadoop Yarn, HDFS). During the measurement we get to know the MapReduce process, as well as the effects of HDFS on MapReduce during the execution of applications.

8. Signaling protocols in 5G core networks (AddICT)
During the practice, students get acquainted with the signaling methods between the 5G core and 5G user equipments (UE), necessary to use 5G services. They analyze the factors influencing the quality of service in an experimental environment, observing and understanding fundamental NAS and NG-APs signaling messages.

9. Resource management of 5G core functions (AddICT)
During the practice, the students learn the practical aspects of efficiently operating 5G core functions. After that, they examine the possible settings of resource management algorithms in an experimental environment.

10. V2X Facilities protocols in practice (MEDIANETS)
During the practice, the students get to know the most important C-ITS/V2X applications and the so called Facilities protocols (CA, DEN, IVI, MAP/SPAT, etc.) directly facilitating their implementations. They examine the structure of the relevant V2V and V2I/I2V C-ITS messages, and analyze the protocol mechanisms in pracice based on the header structures and data elements.
