Subject aims expressed by acquired skills and competences

The aim of the course is to acquaint students with the problems of communication systems that are used in security practice. Emphasis is placed on understanding the communication environment within the integrated rescue system. Special attention is paid to the issue of radio communication in buildings, which are complicated in terms of radio signal propagation. The content of the course is the issue of electromagnetic radiation, a description of its properties in relation to the transmission of information and the interaction of radiation with the environment, especially in the field of radio waves. Furthermore, the principle of communication within the integrated rescue system and operational centers is explained, the legislative character is given, the signal transmission to complicated buildings is described and a practical view of the issue of radio connection is analyzed.

Summary

The course is devoted in the first part to the issue of radio communication in the integrated rescue system, legislative support, the physical basis and the definition of the communication environment. The second part concerns the signal transmission to buildings, which are complicated in nature in terms of radio signal propagation. The third part of the course is focused on the practical side of communication systems.
