IK2510 Wireless Networks 7.5 credits
Wireless networks are everywhere - mobile phone systems, wireless LANs, digital terrestrial televisions, are a few examples of the widely spread systems in everyday life. These networks involve the latest technologies. With emerging new applications of 5G, such as tactile internet, virtual reality, real time autonomous system management, requirements from wireless networks become more stringent. Wireless networks sometimes should operate extremely reliable with very low latency to meet with such demands and at the same time they have to be easy and affordable to use to serve massive number of connected things. To provide connectivity to wide span of mobile applications, these networks require huge investments from those deploying them.
This course provides in-depth knowledge within the area of wireless communications networks. Special emphasis is put on wireless infrastructure deployment, system design, resource management, and the performance analysis of systems for mobile telephony, data, and multimedia communications focusing on the interplay between energy, cost and spectrum resources.

Content and learning outcomes
This course provides a comprehensive and systematic introduction to the theory and practice of mobile data networks. Covering basic design principles as well as analytical tools for network performance evaluation, and with a focus on system-level resource management, you will learn how state-of-the-art network design can enable you flexibly and efficiently to manage and trade-off various resources such as spectrum, energy, and infrastructure investments. Topics covered range from traditional elements such as medium access, cell deployment, capacity, handover, and interference management, to more advanced network design elements such as MIMO (multiple-input, multiple-output) antenna technologies, heterogeneous networks, energy -efficiency, considering different generation of wireless networks such as 4G and 5G.
