Impact of bandwidth, center frequency and spatial position on the results of ultra- wideband power delay profile measurements and accuracy of predictions

The dependence of power delay profile upon bandwidth (temporal resolution) and center frequency is systematically studied using ultra-wideband measurements. The necessary measurement parameters for wideband channel models construction, validation and construction of precise site-specific propagation prediction models and investigation of propagation mechanisms have been detected. Ray tracing and Finite Integration Technique numerical Maxwell´s equation solver accuracy has been estimated and compared on the basis of delay profiles.
