Abstract
Limited research work has been conducted on deterministic modeling of the fifth-generation wireless communications within hospital patient rooms environment. This letter reports a ray-tracing model algorithm for the prediction of multiple-input-multiple-output (MIMO) propagation in the mm-wave band. The furniture effects are predicted in the framework of uniform theory of diffraction. Each piece of furniture is modeled as a group of perfect conducting wedges of random shape and size. The fixed access point has been configured with two forms of radiation patterns: Directional (D) and Omnidirectional (O). However, the mobile user point, remains O. Results indicate that doubling the number of antennas in a MIMO system operating under O-O configuration leads to a notable boost of 9 bps/Hz in channel capacity. The O-O setup creates a rich multipath environment, favorable for MIMO systems, resulting in an average channel capacity increase of 4 bps/Hz compared with the D-O configuration.
