Wireless Network Design



The objective of the course is the presentation of modern wireless communication networks architecture, technologies and techniques. The area of wireless communications and networks is one of the most dynamic areas in the ICT field. The course covers the wireless channel characteristics, multi-antenna techniques, radio resource planning and management, packet scheduling, mobility management, and novel design techniques of wireless networks. At the end of the course, the students will be able to analyze and evaluate main principles and planning design options for wireless communication networks.
