    5. Required knowledge Communication Networks
    7. Objectives, learning outcomes and obtained knowledge The course aims to provide students with a practical approach to the operation and application of today's most common advanced 5G mobile and wireless networks and systems in the digitalization process. The course also aims to present the practical applications of mobile and radio technologies in the fields of Internet of Things (IoT), Vehicle-to-everything (V2X) smart city, Industry 4.0, and agricultural digitalization. The basic knowledge necessary for scaling and operating 5th-generation mobile and wireless networks, sensor networks, and radio and wireless communication solutions and their possibilities and uses will be presented through concrete examples.

    The student who completes the course will be able to:
    - acquire and apply the practical knowledge needed to operate mobile and wireless networks
    - the practical application of mobile and radio technologies and the selection of appropriate communication technologies
    - compare different wireless access technologies from a technical and cost-effective point of view
    - interpret and apply the concepts and knowledge acquired in the course of the subject; recognize situations and problems in which the knowledge acquired is relevant and apply it successfully in future studies.
    - understand wireless and mobile networks from the physical layer to the application layer
