In order to enable the coexistence of an ever- increasing number of communication systems in a limited amount of frequency, the tradi tional static frequency all ocation is not the best solution any longer. Cogni ti ve Radi o (CR) technolog y, based on a dynamic spectrum access, is a possible solution for imp rovi ng the efficiency of spectrum usage. A first step in order to identify the frequency bands that are more suitable for opportunistic usage is to e valuate the degree in which licensed bands are currently used. Although some measurement campaigns have already been carried out, most of them were done in urban environments and only a few in other l ocations. This paper presents results of two measurement campaigns conducted in Romania both in urban and rural environments, covering the frequency range from 25 MHz up to 3.4 GHz. The results are confronted with the frequency allocati on table published by the national authority for radi o communicati ons and a comparison and anal ysis of the obtained data are being made .
