Learning outcomes

Electromagnetic waves free and guided propagation basis phenomena comprehension and their use in telecommunication systems design.

At the end of the course students will be able to design the electromagnetic section of radio systems like GSM, digital TV, etc...

Course contents

Historical introduction to wireless communications: Guglielmo Marconi and the other pioneers of the radio. Area systems and the different concepts of mobility. Differences between real propagation and ideal one; particular propagation mechanisms: troposcatter and ionospheric propagation. Propagation in real atmosphere: ray curvature and attenuation. Application to terrestrial and satellite communications. Introduction to the concept of diversity. The effect of the earth in ideal and real situation. The dominant contribution of attenuation vs. distance. Attenuation due to obstacles. Coverage planning in macrocellular environment: Okumura-Hata formulae. GSM power budget and location probability. The Italian National Model for the certification of coverage. Interference and distribution of channels resources over the territory. Hand-over types. Analogue and digital TV planning. Spectrum efficiency: calculation and optimization. Different access schemes: FDMA, TDMA and Spread Spectrum in the military applications. Cell planning in microcellular environment and in indoor applications The problem of the protection from electromagnetic wave exposure: control of the environmental impact. The concept of Radar and the range formula.
