Radio Links Design

FEKT-NNRSAcad. year: 2013/2014

The subject familiarizes students with basic principles of electromagnetic wave propagation in a real environment and with radio links design in different frequency bands. Students will practice their knowledge on the design of selected radio links in a real environment.

Learning outcomes of the course unit

The graduate is able (1) understand fundamental principles of electromagnetic wave propagation in a real environment, (2) provide overview of basic kinds of radio links and networks, (3) calculate field strength in real terrain and urban area, (4) design of selected kinds of radio links, (5) create empirical model of propagation.

Prerequisites

Fundamentals of electromagnetics (elementar radiation sources, antenna parameters, propagation of plane and spherical wave in unbounded medium, diffraction) are the pre-requisites.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Techning methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write two projects/assignments during the course.

Assesment methods and criteria linked to learning outcomes

A test written during semester (8 points), four individual projects (28 points), final exam (40 points written part + 24 points oral part=totally 64 points).
