A concept of unifying the communications interface between heterogeneous ITS subsystems was presented in this paper. In its first part, it concentrates on causes for and consequences of having heterogeneous networks.

nr 6

W referacie omówiono metody poprawy jakości transmisji w systemie UMTS poprzez redukcję zakłóceń wąskopasmowych oraz międzykomórkowych. Rozważania mają istotne znaczenie w związku z rozpatrywanym wykorzystaniem UMTS w sieci heterogenicznej jako jednego ze znaczących systemów w globalnym systemie poszukiwania użytkowników dróg publicznych wg ustalonych cech.

This report discusses the methods of improving broadcast quality in UMTS system by reduction of narrowband and intercellular interferences. These considerations have important meaning in connection with the use of UMTS in heterogeneous networks as one of significant system in global system of searching for public roads users according to established features.
