Simulation Study of Wireless Coverage in Straight Long Corridors on Container Ship Deck

Abstract

AbstractA wireless coverage simulation based on the ray tracing method is constructed to realize the wireless coverage prediction of the straight long corridor on the container ship deck. The ray reflection model based on the reverse algorithm of the ray tracing method is established to realize the simulation calculation of the point-to-point propagation path. Referring to the recommendations given by the International Telecommunication Union, the Fresnel loss of the straight long corridors and the first Fresnel loss point are calculated, and the ray reflection model is effectively corrected. The least square method is used to fit the double slope of the simulation curve, and the loss formula of the straight long corridors on the deck is obtained. Through experimental simulation, the path loss factors of the fully enclosed corridor are 1.248 and 3.245, and the path loss factors of the semi-closed corridor are 1.251 and 3.444. The simulation results agree with the general conclusions of the ITU recommendation. The simulation can provide the prediction of wireless coverage effect in the design of container ships and provide guidance for the layout design and optimization of base stations of the straight long corridor on container ship deck with different scales.KeywordsRay tracingShipPath lossFresnel lossMultipath propagation
