“…One possible approach to gain knowledge about the wireless propagation channel is to conduct channel measurement campaigns. In the recent years some channel measurement campaigns were performed for maritime scenarios [1], [2], [3], [4], [5], [6], [7], [8]. However, these measurements were conducted with small bandwidth (maximum 20 MHz) and therefore, with low delay-resolution.…”

Abstract-To investigate the broadband over sea wave propagation channel for communication and navigation applications, the German Aerospace Center conducted a broadband channel sounder measurements where the transmit antenna was mounted on a ship and the receive antenna was located on the land. Using this setup, measurements were performed for C-band at 5.2 GHz with a broadband signal of 100 MHz bandwidth. Results are given in terms of receiver height dependent power delay profile, delay spread and mean delay.

“…Recently, there has been a growing interest in the implementation of mobile radio system in the 5 GHz band [9][10][11][12]. As compared to the lower frequency (< 2 GHz) applications in [3,4], high-speed or highcapacity wireless applications can be achieved at 5 GHz.…”

“…As compared to the lower frequency (< 2 GHz) applications in [3,4], high-speed or highcapacity wireless applications can be achieved at 5 GHz. For example, high-speed WiMAX at 5.8 GHz was studied in [9], and microwave landing system at 5 GHz was examined in [11,12]. It has been shown that the 5 GHz band has a good potential for military applications [13], such as off-shore anti-terrorist surveillance or application of unmanned surface vehicles (USVs) in the maritime environment.…”

“…The study of NLoS propagation therefore becomes crucial since the 5 GHz microwave link can be shadowed/diffracted by the large metallic body of the vessels [14] anchored between the on-shore control station and the moving vessel. This makes the mobile radio channel challenging as compared to those reported in [4][5][6][7]9], where most of the research works focus on the investigations of LoS radio-wave propagations in maritime environments. The NLoS propagations over the maritime environments are also different from those in urban areas [15,16] and forested areas [17,18] since the blockage in the maritime environment is caused by large metallic bodies.…”

Abstract-Non-line-of-sight (NLoS) maritime mobile radio channel in 5 GHz band is experimentally investigated in this paper through wideband channel soundings.During the measurements, the transmitter was installed onboard a speed boat, while the receiver was placed on the roof top of a building on shore. Different types of cargo ships anchored off the east coast of Singapore were examined as obstructions for the NLoS propagations. Besides power delay profile (PDP), stand-off distance is introduced in this work to analyze the NLoS propagations associated with three different types of cargo ships. The measured PDPs and stand-off distances are found to be comparable qualitatively with the simulated results using 3-D ray tracing. The reported information is found to be useful for military applications such as unmanned surface vehicles (USVs) in maritime environments or surveillance.

“…Further works in this field have been done in urban and suburban environments [5], [6]. Besides, although [7], [8] and [9] present experimental measurements of propagation characteristics for maritime radio links, they do not apply to conditions covered by our study. To the best of the authors' knowledge, buoy-to-ship path loss characteristics over sea at 5.8 GHz near urban environments have not been investigated.…”

Abstract-Current marine wireless communication systems used for monitoring applications based on buoys suffer from lots of weakness. Many research works concern the design and development of new technological applications to improve marine communications. Particularly, a wireless communication system based on WiMAX standard at the 5.8 GHz band (license-exempt band) could be a good candidate. As an initial task, a propagation channel measurement campaign in maritime environments was carried out to investigate the impact of the wireless channel in different situations. This work provides large scale path loss measurements over sea around urban environments. In particular, a radio link between a buoy and a ship at 5.8 GHz is studied. NLOS (Non-Line-Of-Sight) paths are investigated in depth and they are compared to LOS (Line-Of-Sight) paths. The designed measurement system is described and the experimental measurements are shown. An empirical model is obtained using these experimental data and the key wireless channel parameters are analyzed. In addition, the empirical model is compared to the free space and two-ray theoretical models. This investigation is useful, among others, for planning Worldwide Interoperability for Microwave Access (WiMAX) networks offshore around these challenge environments.Propagation channel measurements; Sea; WiMAX; urban environments;
