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), WiFi, PANs, 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.
Contents
The course consists of three parts: a theoretical part, laboratory exercises and a seminar.
The theoretical part (VAMK and UVA): Signal propagation and wireless channel properties, Modulation and demodulation of radio signals, Cellular basics: reuse factor and capacity, Access technologies (FDMA, TDMA, CDMA, OFDMA), Access technologies (CSMA/CA, ALOHA, and other MAC protocols for short range wireless communications), Cellular network standards: GSM/GPRS/WCDMA/HSPA/LTE, Short-range wireless standards: T/IEEE802.15.4/6LowPAN/LoRa, Routing/Synchronization/Clustering.
Laboratory exercises (VAMK): Spectrum analysis, modulation and demodulation in Matlab, PAN: IEEE802.15.4 network constructing and testing, LoRa network constructing and testing.
The seminar (UVA): Beside the intensive theoretical and practical parts, there will be also seminar-type part where each student should prepare a topic in related area and write a small report and present his/her work in a dedicated session. The topics can be determined by the teacher. The purpose of the seminar is to train students for material collection, teach them how to write technical reports and how to present their ideas publically. Moreover, to provide more knowledge about communication networks. However, the following topics are given as examples: Bluetooth Protocols and Industrial applications, Zigbee Protocols and Industrial applications, Ultra-wide-Band Technology for IoT, Wireless Sensor Networks for IoT, Industrial Requirements for Wireless Networks, Wireless Automation, Security in IoT, LTE- Advanced Applications in Industry, 5G and IoT, Wireless Broadband over MIMO-OFDM, IoT Application in Energy Industry, Satellite Networks.
