Abstract
For a long time, the development of maritime communication has been restricted by the low data rate, high-latency and high cost of the current communication systems. The upgrade of new generation mobile communication technologies is attracting more and more attention to conduct a shore-based broadband mobile communication network with high-latency and high reliability to serve the maritime industries. This paper presents a solution by means of building a ship-to-infrastructure (S2I) and a ship-to-ship (S2S) wireless communication networks for an offshore region. We characterize the S2I and S2S channels at 5.9 GHz band based on the channel measurements in realistic environments. The channel characteristics, including power delay profile, delay spread, propagation path loss, are extracted and analyzed. In view of the difference between marine and terrestrial communications, we analyze the influencing factors of the offshore water, including effective reflection, divergence and shadowing from the water surface, and diffraction loss caused by the earth curvature. We also predict the power coverage range and the channel capacity for S2I and S2S wireless communications. Finally, the communication performance is evaluated according to the channel measurement and characterization analysis. The research results can be a reference for the construction of maritime communication networks.
Highlights
To date, the new generation of mobile communication technology represented by Conventional communication systems used in offshore waters mainly include maritime radio communication, maritime satellite communication, and shore-based mobile communication based on terrestrial cellular networks
The temporary S2I mobile communication network was built on the basis of a highprecision signal generation system, including a time-division multiplexing single-input single-output (SISO) channel sounder provided by Super Radio AS in Norway and Norwegian University of Science and Technology (NTNU) [20], transmitter (Tx) and receiver (Rx) antennas, and high-resolution global positioning system (GPS) receivers
In this paper, we mainly focus on the key characteristics, including power delay profile, delay spread and propagation path loss, which are essential for the research of maritime wireless channels
Summary
The new generation of mobile communication technology represented by Conventional communication systems used in offshore waters mainly include maritime radio communication, maritime satellite communication, and shore-based mobile communication based on terrestrial cellular networks. The maritime radio communication systems are customarily operated in MF/HF/VHF bands with a short coverage and a low data rate [6,7,8]. The current maritime wireless communication systems are difficult to meet the demand for smart ocean construction. It is attracting more and more interest to build a network on the basis of terrestrial communications for the offshore waters, such as 4G-LTE and
