Abstract The scarcity of available radio spectrum presently limits the extension of the modern, multi media enhanced internet into the mobile domain. One approach to alleviate this limitation is the development of flexible, optimized mobile radio networks, which will be able to adapt to the spatial and temporal variation in capacity demand, in order to increase the overall spectral effi-ciency of the joined set of radio networks. However, one of the challenges created by this approach is the dynamic changing of spectral neighborhood relations, and thus of interference between systems. While in a static scenario the frequency planning is predetermined and fixed, a dynamic, adaptive allocation of spectrum requires flexible prediction of expected interference between different radio systems. Required guard bands decrease the overall spectral efficiency of the system, and therefore need to be minimized, or taken into ac-count as a constraint when making optimizations. A simulation-based approach for assessment of the coexistence of DVB-T and UMTS in a hybrid radio system with flexible, dynamic spectrum sharing is presented. A simplified simulation scenario has been developed in order to cope with the computationally expensive modeling of a multi-cellular, mobile communication system. First results are presented for the interference and degradation of UMTS operation in the presence of a neighboring DVB-T system. In an outlook, possibilities for future improvements to the simula-tion results are shown.
