Prediction modelling of indoor radio propagation for the pico-cellular environment

An analytical method for the prediction of power delay profiles within a room environment is presented. The model works directly on a 3D description of a room. This simple geometry-based reflection model for the calculation of delay spread values has been shown to work well with measured results. The maximum and typical delay spreads have been found by both model and measurement to be largely determined by room size: the larger the room the greater the delay spread. The narrowband characteristics have been modeled and found to agree well with the standard theory.<>
