International audience. Millimeter (mm)-waves band has become a promising option for fifth-generation (5G) near-infinite data rate and ultra-low latency communications. Despite all recent achievements, engineers are still facing technical challenges for the assessment of indoor propagation mechanisms at extremely short wavelengths. In this paper, a mathematical-based deterministic Ray-Tracing Model (RTM) has been derived for the prediction of Path Loss (PL) within a hospital patient room while ensuring users freedom of mobility. Directional, and omnidirectional radiation patterns have been considered at both transmitting and receiving ends of the channel, respectively. For the RTM validation, broadband propagation measurements have been conducted under Line-Of-Sight (LOS) condition. The predicted and measured channel responses are found to be in a good match for all RX positions throughout the room. Furthermore, both predicted and measured path loss exponents (n) are found to be about 1.55. The predicted n agrees with the values reported in the literature.
