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.
