Learning Outcomes
After completing the course successfully, the student will understand the main concepts of wireless communications networks and will be able to compare wireless networks with respect to costs, performance, efficiency, requirements, and applications. She will understand the technical differences between different network standards including cellular networks (GSM, 3G, 4G, 5G), WLAN, WPANs, etc. Moreover, they will have good knowledge for different aspects about physical layer, mobile channels and radio propagation, medium access control, modulation and coding. Furthermore, there will be several practical experiments to demonstrate important concepts in wireless networks. Emphasis will put on wireless communication and networking for the application Internet of Things (IoT) in energy industry.
Student's Workload
135 h, containing 70 h of scheduled contact studies.
The assessment of student’s own learning 1 h is included in contact lessons.
Prerequisites / Recommended Optional Courses
Local Area Networks, Basics of Telecommunications.
