Abstract

Cilj ovog magistarskog rada je bio prezentirati prednosti GSM frekvencijskog planiranja korištenjem mjerenja koja obavljaju aktivne mobilne stanice. U uvodnom dijelu opisana je arhitektura GSM tehnologije. U središnjem djelu objašnjene su najzastupljenije metode frekvencijskog planiranja kao i izazovi koji se susreću prilikom modeliranja frekvencijskih planova pomoću alata za planiranje. Kao dodatak u ovom magistarskom radu, razrađena je metoda računanja troškovne funkcije koja može konzistentno tretirati frekvencijske planove neovisno o tipu frekvencijskog skakanja. Cilj ponuđene troškovne funkcije jest kvantiziranje kvalitete frekvencijskih planova radi njihove međusobne usporedbe i procjene potencijalnih performansi. U zadnjem poglavlju uspoređene su stvarne performanse odabranog grozda ćelija prije i nakon implementacije novog frekvencijskog plana modeliranog uz pomoć mjerenja aktivnih mobilnih stanica.

Abstract (english)

The aim of this Master Thesis was to present the advantages of GSM frequency planning by using measurements form active mobile stations. The introductory part describes the architecture of GSM technology. The central part is dedicated for explaining the most common frequency planning methods, together with the challenges that are faced when modeling frequency plan with the help of a planning tool. As an addition, an alternative way of calculating the cost function is elaborated, which can consider frequency plans independently on the hopping mode. The aim of the suggested cost function is to quantify the quality of each frequency plan, in order to have a compare them and evaluate potential performances. In the last chapter are compared the performance of a cell cluster before and after the implementation of the new frequency plan produced with the support of measurements from active mobile stations.
