Ships are constructed using metals which are good reflectors of electromagnetic (EM) waves [1]. Therefore, signal propagation in a sea environment is more complex as compared to propagation indoor. This complexity would allow us to study the feasibility of applying narrowband or/and broadband signals for wireless communication on board a boat (transmitter) to the shore (receiver) while being blocked by a vessel in the sea (NLOS). This report documents the joint collaboration project between NTU and ST Electronics Pte Ltd for the investigation and characterization of Non-Line of Sight Propagation (NLOS) in a sea-shore environment. The C-band frequencies of 5.15GHz for narrowband propagation and 5.8GHz for wideband propagation were used for the sea trial. Direct Spread Spectrum Sequence (DSSS) sounding technique using Pseudo Noise (PN) and Continuous Wave (CW) were used for the channel used for transmitting (on a boat) and receiving (on shore). This report will focus only on wideband signal propagation. Analysis of the data obtained from sea trial was carried out.
