Module: Wireless Systems and MIMO Technology (40233)

About the Module

This module deals with the most relevant wireless communication systems and discusses their architecture, interfaces, and services. The corresponding air interfaces are explained and compared. As an example of today's broadband mobile systems based on IP technology, LTE is presented in details. System planning and maintenance issues are introduced as well. A special highlight consists of the economic importance and costs of the different components of the system. Then, the module focuses on a fundamental component of modern wireless technology, namely Multiple-Input Multiple-Output (MIMO) technology, i.e., using multiple transmission and reception antennas in order to create an additional “spatial" dimension for signaling over wireless channels. The target is to enable students to understand MIMO technology and its main implications and trade-offs at the system design level.
