Mobile Communications: Technology and QoS

Spring Semester (Frühjahrssemester)

Lecturer
Dr. Marc Kuhn

Schedule
Thursday 08.00 - 12.00;  LFW C 4

Overview
A few selected overview slides per chapter

Objective
Introduction to mobile wireless communications, including characteristics of the wireless channel, PHY layer technologies (for example MIMO, OFDM, etc.) and MAC layer schemes; comparison of different cellular standards including 5G; definition of QoS and support of QoS in wireless networks; understanding QoS measurements, their evaluation and benchmarking in cellular networks.

Language
English

Summary
Based on an introduction to wireless communications, the lecture course covers: cellular systems (focus on 4G, outlook on 5G), PHY technologies (for example MIMO, OFDM etc.), MAC schemes (e.g., in detail the IEEE 802.11 MAC), mechanisms supporting QoS in wireless networks, QoS measurements and evaluation, benchmarking.

Content
  • Introduction
  • Wireless channel, propagation of electromagnetic waves, antenna structures
  • Mobile communication, modulation techniques, OFDM, MIMO
  • Wireless networks (cellular networks, access networks)
  • Wireless standards (e.g. UMTS, LTE, LTE Advanced, 5G, IEEE 802.11n)
  • Quality of service (QoS) in wireless networks (definitions, Key Performance Indicators)
  • QoS measurements (e.g. voice quality, coverage, delay) and their statistical evaluation
  • Benchmarking (methodology, statistical methods and models)
