Telecommunication Networks

The course cannot be taken simultaneously with:

Telecommunications Technologies (X32TET)

Prerequisite:

Safety in Electrical Engineering 1 (X12BP1)

Lecturer:

Ivan Pravda (gar.), Jaromír Hrad (gar.), Jiří Hájek

Tutor:

Ivan Pravda (gar.), Jaromír Hrad (gar.), Jiří Hájek, Lukáš Vojtěch

Supervisor:

Department of Telecommunications Engineering

Synopsis:

The subject provides basic overview of communication, i.e. transmission from information source to information sink. It introduces basic terms and principles of information transmission, services of telecommunication networks, quality of services, traffic engineering and dimensioning of networks elements. The application of these principles and methods is demonstrated on the existing communication networks - ISDN, data transmission networks, fixed and mobile networks.

Requirements:

In order to obtain the credits, students have to meet the following conditions:

1) Be successful in the tests from the given tasks (at least 50% score).

2) Succesfully deliver 2 assigned reports.

3) Participate in all practical exercises.

4) Successfully pass the assessment test (at leat 66% score).

Syllabus of lectures:

1. Basic terms. Regulation and standardization in telecommunications.

2. National holiday - no lectures

3. Communication chain, source of information - transmission and switching element - information sink. The concept of networking.

4. Description of a source, transmission and switching element, types and basic characteristics of these elements.

5. Technologies for information transmission and its protection.

6. Open Systems Interconnection (OSI) model.

7. Multiple utilisation of transmission media. Modulations.

8. Transmission media and their utilisation. Transmission systems.

9. Telecommunication switching systems - basic characteristics. Signaling.

10. Principles and properties of mobile telecommunication networks. Data transmission in host networks.

11. Narrowband and broadband ISDN networks. Intelligent networks.

12. Services in communication networks and their classification.

13. Traffic load, service systems and their traffic models, basic parameters.

14. Evaluation of quality of services (QoS) and network performance (NP).

5. Laboratory exercise - Optical communications (implementation of a transmission path PC - optical line - PC)

6. Assessment test.

7. Assignment of credits.

Study Objective:

Students will get familiar with the basic principles of communication and its technical principles at all levels, from signal transmission in specific physical environments to the services provided in electronic communication networks, including standardization, legislation and organizational measures.
