Learning outcomes |
In an era of massive use of mobile phones, students will acquire knowledge to develop work in fields such as wireless point-to-point and point-to-multipoint network design, mobile communications system planning, quality control and test of cellular systems, tele traffic engineering, as well as conception and operation of wireless local and metropolitan area networks. A particular emphasis is given to the formal and rigorous modelling of radiation and propagation processes, with enough detailed models for the cellular planning, to the analysis and proposal of solutions for tele-traffic problems (to obtain the supported traffic for a given grade-of-service, represented by the blocking probability and call dropping thresholds, etc.), the design of high capacity point-to-point links and the conception of indoor networks. One of the involved key ideas is the possibility of the integration of a considerable part of the aspects of planning into graphical cellular planning tools.

Syllabus |
1 – Motivation to telecommunications: historical evolution of telecommunications and the block diagram for a communications system.
2 – Introduction to radio wave processes: antennas, propagation, interference and frequency reuse. Dependence of the path loss on the frequency. Expressions for the gain of the principal types of antennas; the Fresnel ellipsoid, Fraunhoffer distance, and Doppler effect. Dependence of the carrier-to-interference ratio on the coverage and reuse distances.
3 – Satellite communications.
4 – Modulation, coding and topics on signal processing.
5 – Computer networks (including the OSI model) and tele-traffic issues (blocking, handover failure and delay), including mobility.
6 – Mobile and wireless communications systems (GSM/HSCSD/GPRS/EDGE, UMTS, HSPA, MBS, IEEE 802.11, IEEE 802.16, LTE and 5G) and their architectures. Topics of microwave radio links.
7 – Cellular planning and multi-service.

Teaching Methodologies and Assessment Criteria |
The theorethical contact times (2 h per week) aim at acquiring theorethical knowledge associated with the programme contents of the curricular unit. The theorethic-practical times (1 h per week) aim at acquiring pratical knowledge, by solving problems and practical exercises. In th elaboratory classes (1 h per week), students develop practical laboratory tasks.
Student evaluation is according the following proposal.
