The dual-directional characteristics of propagation in a medium-size lecture room at two frequency bands, 10 GHz and 60 GHz, are assessed in this work through directional measurements and ray tracing simulation. Ray Tracing is used as a tool to interpret measurement results, but also as a propagation model to simulate mm-wave propagation. For what concerns the latter aspect, ray tracing has been calibrated vs. measurements and the accuracy in terms of dual-directional simulation of the channel has been evaluated
