Indoor wideband radio propagation measurement system at 1.3 GHz and 4.0 GHz

The development and operation of a dual-band time-domain radar system used to measure indoor multipath propagation characteristics in several office buildings and factories are described. The system operates at 1.3 GHz and 4.0 GHz and uses 4-ns RMS pulses to provide estimates of indoor radio channel impulse responses. The effects of antenna diversity, frequency scaling, and topography on indoor radio system design are quantified through analyses of measured propagation data. The data are used to develop and refine wideband channel models for multipath propagation in factories and open-plan office buildings and provide insight into the validity of geometric modeling techniques for predicting channel characteristics
