mmWave Propagation Prediction using Hardware- Accelerated Monte Carlo Path Tracing

We have developed a hardware-accelerated Monte Carlo path tracing tool based upon a novel mmWave propagation prediction model. Much faster than conventional tools, it is designed to meet the needs of large-scale coverage and interference studies. The results of initial validation against conventional ray- tracing simulations and measurements in an indoor office environment at 60 GHz demonstrate the merit of the approach. Overall, prediction accuracy was comparable between the two approaches in this scenario, while Monte Carlo path tracing was more than an order of magnitude faster. With further validation and suitable building and terrain data, this method should also be suitable for outdoor and mixed environments.
