Results of Indoor Propagation Measurement Campaign at 1900 MHz

Abstract

For the design of indoor picocellular systems in the frequency bandof 1800/2100 MHz, a signal propagation modelling is needed. Empiricaland semi-empirical models represent an efficient approach to thecoverage prediction. For these models, suitable empirical parametersmust be provided. The indoor propagation measurement campaign in thefrequency range of 1900 MHz was carried out in several multi-flooredbuildings in Prague and Brno . For the campaign a special portablemeasurement system was developed. Based on the measurement results, themodel parameters were derived. Optimised parameters are presented fortwo basic models (empirical and semi-empirical) according to the indoorenvironment classification. The results are compared to standard modelsas well. Accuracy and validity of derived models are discussed.
