Intra-ship Channel Characterization for Smart Maritime empowered by 5G

The vision of smart maritime requires a seamless high-data rate wireless connectivity, which can be realized by the fifth-generation communication system (5G). As one of the most widely used 5G frequency spectrum, 3.5 GHz is a promising candidate band to provide high-quality wireless coverage inside ships. Hence, in this paper, the wireless channel in the intraship scenario at 3.5 GHz is characterized through extensive raytracing (RT) simulations. Channel parameters are extracted and analysed in terms of root-mean-square delay spread (RMS DS), Rician K-factor (KF), azimuth/elevation angular spread of arrival/departure (ASA, ASD, ESA, ESD), cross-polarization ratio (XPR), and their cross-correlations. Based on these results, we provide valuable insights into the system design and evaluation for the 5G in the intra-ship scenario.
