In 3rd generation cellular systems using WCDMA radio access technology (RAT) one operator could theoretically operate it's network by using only one frequency when another operator in the same area uses the immediate adjacent frequency. Then, on contrary to other systems, the adjacent channel interference (ACI) is coming entirely from another operator. Since most likely the network plans will be completely independent, the only means to combat this ACI is applying appropriate filters. This paper shows results on a study of the influence of 2 macro operators using WCDMA RAT in the same area in adjacent channels, by applying the filter values specified in 3GPP TS 25.101and 3GPP TS 25.104 . Two cases, one from an urban and one from a suburban area are shown. Example results on outage, coverage probabilities, quality of service, transmit power distributions etc. are presented with and without the second operator present and compared with each other. In conclusion of the comparison it is shown, that in macro cellular scenarios the influence of both operators on each other is negligible
