Indoor Measurement Based Verification of Ray Launching Algorithm at the Ka-Band

Ray launching (RL) algorithms are widely employed in indoor radio frequency (RF) design and planning, where a trade-off exists between the prediction accuracy and the computational cost. In this paper, a RL-based channel simulation is carried out in a simplified three-dimensional (3D) model of a typical classroom environment at the Ka-band. Channel measurements are conducted in a practical scenario to verify the accuracy of the simulations. The path loss and root mean square (RMS) delay spread of the propagation channel obtained from simulations and measurements are reported and compared, which show good agreements.
