Radio Wave Propagation Characterization between Adjacent Decks on Board Ships

The objective of this paper is to characterize the electromagnetic waves propagation between adjacent decks on board a ship. First, narrowband measurements were conducted at 2.45 GHz to study the radio coverage. Different configuration scenarios where considered. Then, double directional channel sounding was performed at 3.5 GHz to determine the propagation mechanisms and multipath parameters in this hostile environment. The aim of these measurement campaigns is to find a solution to maintain the connectivity of a wireless sensor network between different decks on a ship in spite of the metallic structure of decks.
