Kuten kurssin nimi kertoo, kurssilla tehdään elektroniikka-aiheinen projekti. Kurssilla oppii siis projektimaista työtapaa eli projektilla on alku, keskivaihe ja loppu ja se alkaa projektisuunnitelmalla ja päättyy projektin päätösraporttiin. Projektissa tehtävän laitteen speksaaminen alkaa luonnollisesti heti projektisuunnitelmaan kuuluvalla vaatimusmäärittelyllä, josta saadaan myös valmiin laitteen arviointikriteerit. Projektitiimin järjestäytymiseen noudatetaan kurssilla tarjoiltua mallia, jossa projektitiimi itse projektipäällikkövetoisesti tekee projektina jonkin elektronisen kokonaisuuden. Projektitiimi asettaa itse aikataulunsa kurssin raameissa ja resurssinsa (aika, raha ja työtunnit). Sähkötekninen sisältö vaihtelee vuosittain projektin mukaan, mm. elektroniikkakomponenttien käytännön ominaisuudet, elektroniikkasuunnittelu ja terminen mitoitus käytännössä, sulautetun järjestelmän suunnittelu, toteutus ja ohjelmointi, häiriösuojaus, tehoelektroniikan sovellukset, laitteen suojaus ym.

The main goal of this course is to make a student familiar with 5G communication standard from industrial perspective. Brief introduction of the main technologies and methods like millimetre waves, beam forming, and network slicing will be discussed to give a good foundation for further research. At the end of the course the student be able to understand basics of technologies used in 5G and understand the impact they bring to energy, transportation and other industries. This will allow the student to better understand how 5G can be used in their field of work and study and spark interest for further research on this topic.

This course will introduce the role of IoT in modern life as well as basics of concepts that are necessary to understand IoT systems. The definitions and explanations for the terms System, Information, and Network will be considered in the first part of this course. Later we will learn about applications of theoretical concepts in some practical cases. The course is designed for people who want to understand what role IoT systems play in Fourth Industrial Revolution known as Industry 4.0 and to help them find relevant applications for these technologies in their work and studies. The course is divided into 4 chapters, each has theoretical part and a short assignment in a quiz form at the end, as follows: 1. Introduction; 2. Systems, Information, and Networks; 3. Probability and Game Theory; 4. Applications of IoT systems.
