Abstract:Diplomska naloga opisuje profesionalni radijski sistem TETRA, možnost uvedbe satelitske povezave TETRA omrežij, tehnične značilnosti TETRA sistema, integracijo TETRA sistema s sateliti, prednosti in slabosti njegove uporabe in namene, v katere se uporablja. Ugotovitve so pokazale, da je povezovanje TETRA omrežij preko vmesnika ISI mogoče in da obstajajo potrebe po razvoju TETRA sistema in učinkovitejšega pretoka podatkov. Primer možnosti uporabe TETRA omrežja prikazuje izvedba simulacije z odprtokodnim programom Radio Mobile. Pri poskusu postavitve radijskih naprav po terenu in vnosu parametrov se je izkazalo, da ponekod povezave nekaterih radijskih naprav niso možne zaradi dejavnikov, kot so razgibanost terena, vremeski vplivi, lomljivost signala. Tu se pojavi potreba po uporabi satelitskih povezav, saj je v primerih hudih naravnih nesreč pomemben hiter odziv reševalnih enot. Program Radio Mobile je zasnovan tako, da omogoča načrtovanje postavitve radijskih naprav, ker prikaže vse dejavnike, ki lahko vplivajo na uspešnost povezav med radijskimi napravami.

Title:POSSIBILITIES OF IMPLEMENTATION OF TETRA NETWORKS SATELLITE CONNECTION
Abstract:The thesis describes the professional TETRA radio system, the possibility of introducing TETRA Network satellite connections, technical features of the TETRA system, integration of TETRA with satellites, the advantages and disadvantages of its use and the purposes for which it is used. The findings show that the integration of TETRA networks via ISI interface is possible and that there exists the need for the development of TETRA system and efficient data flow. An example of the possible use of TETRA network is shown by the simulation made with Mobile Radio open source program. With the attempt of installing radio equipment in the area and the input of parameters, it appeared that the links of some radio devices are not possible due to factors, such as the variability of the terrain, weather, breaking the signal. Here the need for the use of satellite links can be observed, as in cases of severe natural disaster a fast response of rescue units is significant. The program Radio Mobile is designed in a manner which allows us to design the installation of radio devices, as it displays all the factors that may affect the performance of radio links.
