60 GHz radio wave propagation prediction in a hospital environment using an accurate room structural model

Accurate radio wave propagation prediction is crucial in designing wireless instruments for medical use. In this paper we simulate the 60 GHz radio channel in a hospital ultrasonic inspection room using ray tracing based on single-bounce scattering. The scattering is calculated with a single-lobe directive model and the room structure is modeled with a large point cloud, acquired via laser scanning. It is shown that the scattering model is able to predict the power delay profile with a proper scattering parameter. It is also noticed that measuring the environment dimensions with laser scanning is a suitable method in order to obtain appropriate prediction of the propagation channel.
