Abstract
Oppfinnelsen angår en fremgangsmåte og et apparat for å bestem- me svekning av radiobølgeutbredelse i det ønskede område i et radiosy- stem. Et minst flerdimensjonalt vektorkart som beskriver en basestasjons omgivelser, benyttes ved bestemmelse av dekningsområdet for systemets basestasjon. Utbredelsessvekning i noen punkter i det ønskede området bestemmes ved hjelp av en stråle-opptrekkingsmetode. l andre punkter i det ønskede området beregnes utbredelsessvekningen med en empirisk modell, og modellens parametere initialiseres ved hjelp av resultatene som oppnås med stråle-opptrekkingsmetoden. Ved hjelp av fremgangsmåten kan Utbredelsessvekning beregnes mye raskere enn tidligere.The invention relates to a method and apparatus for determining the weakening of radio wave propagation in the desired region of a radio system. A least multidimensional vector map describing a base station environment is used in determining the coverage area of the system base station. Propagation impairment at some points in the desired range is determined by a beam-drawing method. At other points in the desired range, the propagation attenuation is calculated with an empirical model, and the model's parameters are initialized by the results obtained by the beam-drawing method. Using the method, Distribution Weakness can be calculated much faster than before.
