This paper describes a newly developed three dimensional ray launching model for complex indoor environments. The model is capable of predicting detailed temporal and spatial multipath. To investigate and evaluate the accuracy of this model, predictions are compared with detailed measurements recently taken in an office environment. Power Delay and Power Azimuth Spectra are measured using a multielement Medav channel sounder operating with 120 MHz of bandwidth in the 5 GHz band. Prediction accuracy was found to be sensitive to the accuracy of the basestation height, the permittivity of the surrounding materials and the number of reflections permitted in the model. Overall, the results indicate that with careful modelling and well calibrated measurements, good site specific spatial and temporal multipath agreement can be achieved.
