Introduction to wireless systems and networks. Evolution of wireless mobile communication systems. Propagation and path-loss in wireless communication. Analytical and empirical propagation path-loss models. Types of fading and channel characterization. Radio planning principles for cellular systems. Types of interference. Mobility management and handover process. Techniques for efficient allocation and management of radio resources. Digital modulation techniques for mobile communication systems and channel capacity. Medium access control protocols and multiple access techniques FDMA, TDMA, CDMA and OFDMA as well as how they are implemented in the respective wireless cellular systems GSM, GPRS/EDGE, UMTS, LTE, LTE-A. Introduction to the technological features of future 5G systems.
The course offers an introduction to mobile communication networks, i.e. GSM, GPRS, UMTS, LTE and LTE-A. The operating principles and main features of these systems are studied, and the course concludes with a short introduction to the features of future wireless networks (5G).
Upon completion of the course the student will be familiar with the concepts of cellular radio coverage, cellular planning and radio resource management (Call Admission Control, Wireless Channel Capacity and Quality, Dedicated and Shared Channel Management, Service based QoS differentiation etc.) at advanced mobile communications systems.
The lab part of the course includes a set of carefully selected exercises to accelerate the learning process. Through simulation, the students study basic processes of a mobile telephony system, such as Call Admission Control, Management of radio channel quality in Line Of Sight (LOS) and NLOS scenarios, as well as transmission rate management using Adaptive Modulation and Coding (AMC).

|Learning Activities and Teaching Methods |
The main teaching method followed is the traditional face-to-face lectures in class. An electronic presentation program, a portable computer and a projector are utilised at each lecture. Interactive images and videos are used in order to improve the understanding of the main disciplines of the course. All the presentations, resolved exercises, multimedia material, notes, exercises to be delivered, announcements, web links, etc. are updated frequently in eclass, a flexible e-learning platform. In the laboratory part of the course, the students develop code that simulates basic processes of mobile communications systems in order to better understand the relative theory.
