“…In the Mare-Fi project [9], the problem of broadband maritime Internet access for fisheries was solved by creating a novel communications solution based on TV white spaces frequencies in the 700 MHz band. MARBED -MARitime wireless networks testBED was created within the project and was able to validate the solution for one land station and a fishing ship in the Atlantic coast close to Porto, Portugal [8], [10], [12]. With this solution, it was possible to provide broadband Internet access from shore at distances up to 10 km.…”

“…The provisioning of broadband Internet access close to shore is possible in locations where either mobile operators coverage is available or Wi-Fi-based long distance links can be deployed [8]- [10]. However, it becomes challenging to provide access to the Internet when distances in the order of tens or hundreds of kilometers from shore are required.…”

Height Optimization in Aerial Networks for Enhanced Broadband Communications at Sea

The Blue Economy has been growing in sectors such as offshore renewable energy, aquaculture, marine biotechnology, and deep sea mining. However, suitable wireless and mobile communications are lacking offshore. On the one hand, there is no coverage from terrestrial networks; on the other hand, satellite communications are still narrowband and expensive. Recently, the use of multi-hop airborne communications has been proposed to extend the coverage from terrestrial networks offshore but the communications range of these solutions is highly dependent on the height of the communications nodes. In this paper, we study the RF signal propagation in the maritime environment when the height of the receiver is changed and propose a position control approach for airborne multi-hop networks that maximizes the network capacity by taking full advantage of the signal reflections on the sea surface. The results obtained show that the proposed approach can provide lower propagation losses and higher network throughputs than random or fixed height approaches.

“…Within the project, a testbed, named MAREBED -MARitime wireless networks testBED, was created to evaluate the communications solution and consisted of 2 land stations and 8 fishing ships in the Atlantic coast, about 10 nautical miles from Porto. This testbed provided broadband ship-to-shore communications up to 10 km from shore using TV white spaces frequencies in the 700 MHz band [7] [9] [12]. This testbed was used to carry out a pilot for providing free Internet access to fishing ships, where the fishermen can use standard equipment, such as their smartphones, to access the Internet at sea.…”

“…In addition, providing satellite access to a large number of devices is expensive, as it requires proprietary hardware and monthly fees [10], and a consequent high cost per bit; moreover, the delay associated with satellite communications may reduce the quality of realtime communications such as voice and video conference calls. Therefore, accessing the Internet in a cost-effective way is only possible near shore in two scenarios: 1) using a 3G/4G network when it is available; 2) within the range of Wi-Fi-based long distance links, typically up to 10 km, as shown in the Mare-Fi project [9][11] [12].…”

The growth of the Blue Economy has been boosted by a set of traditional and new activities including maritime transportation, fisheries, environmental monitoring, deep sea mining, and inspection missions. These activities are urging for a cost-effective broadband communications solution capable of supporting both above and underwater missions at remote ocean areas, since many of them rely on an ever-increasing number of Autonomous Surface Vehicles (ASV), Autonomous Underwater Vehicles (AUV) and Remote Operated Vehicles (ROV), which need to transmit large amounts of data to shore. The BLUE-COM+ project has considered the usage of helium balloons to increase the antenna height, and overtake the earth curvature and achieve Fresnel zone clearance, combined with the use of sub-GHz frequency bands to enable long range communications. In this paper we present the results obtained in three sea trials. They show that the BLUECOM+ architecture is capable of supporting human and system activities at remote ocean areas by enabling Internet access beyond 50 km from shore, live video conference calls with the quality of experience available on land, and real-time data upload to the cloud by ASVs, AUVs and ROVs using standard access technologies with bitrates above 1 Mbit/s.

“…The Mare-Fi project is a research and development effort enabling affordable Internet access for fishing industry using Wi-Fi-based high bitrate and long range maritime communications [13]. The experiments carried out in Mare-Fi allowed the authors to provide ship-to-shore broadband IP-based communications up to 10km from shore, however the backbone communication is limited to single-hop nodes [14] [15] [16]. In FLEXUS, multi-hop communication using Wi-Fi is explored.…”

FLEXUS unmanned surface vehicle was designed in the context of the Internet of Moving Things. This small catamaran weights less than 15kg and is less than 1m long, making it a very convenient vehicle with reduced logistics needs for operations in real outdoor environments. The present paper describes the resulting system both in terms of design and performances. Based on the requirements for this project, the subsystems composing the vehicle are described. Results obtained from experiments conducted in outdoor conditions have successfully validated this design and are presented in this paper.
