Indoor propagation modelling is demanded for the design and maintenanceof indoor wireless services. Empirical modelling seems to be the mostefficient approach. Even so there are many studies dealing withempirical models for indoor propagation, the results can be hardly usedfor local buildings without modifications. There are several specificarchitecture styles and used materials. The indoor propagationmeasurement campaigns in the frequency range of 900 MHz were done intwo typical multi-storey university buildings in Prague. Based on themeasurement results, the easy-to-use empirical propagation predictionwere derived for both of the buildings with satisfactorily accuracy.variations of the models were studied. The models are being implementedinto a CAD software tool for complex design of indoor cellular systems.The project continues using a similar approach for other frequencybands. In the same time, other novel ways of semi-empirical modeling ofindoor propagation are investigated.
