Analysis of wideband radio channel properties for planning of next-generation wireless networks

This paper analyzes the application of wideband channel properties in the radio planning of wideband wireless networks. The definition and prediction of delay spread (DS) and angular spread (AS) are first discussed. A wideband high-resolution measurement campaign is then described which was conducted in an urban area using a 3-D high-resolution channel sounder. The comparison between measured and predicted data shows different prediction accuracy of DS and AS, with a 3-D ray tracing approach, for two different propagation environments.
