Valid channel models for the future generation of communications (5G) are paramount for system design and performance analysis. The METIS map-based model is based on 3D ray tracing principles with a simplified description of the environment and it is suitable for 5G communications. In this paper, the model is first described and then validated through comparison with indoor measurements performed at mmwave frequencies. Specifically, the dominant paths trajectory and power values are compared for three relevant scenarios: line of sight (LOS), non-line of sight (NLOS) and obstructed line of sight (O-LOS), where an object blocks the LOS path. Agreement between simulations and measurements is remarkable.
