“…WiMAX can be used as an alternative to satellite links for multimedia communications among different naval units which are in the range of few kilometers. Experimental activities and results of WiMAX system in marine scenario were already discussed (see [5], and [6]). In this scenario the BS or the CPE can be interfered by devices that are on board of the same ship (i.e.…”

This paper presents some experimental results about the robustness of a WiMAX system against interfering signals. In particular, this work presents a WiMAX performance comparison when two different types of interfering signals were generated: a continuous wave and a rectangular pulsed wave. Both of them were tuned at the same working frequency of the WiMAX system (i.e. 2.55 GHz). The former is typical of some attackers or dud devices, the latter, instead, is very similar to the signals generated by radars. In this work IP throughput performance and the WIT (Voice over IP) perceived Quality of Service (QoS) were evaluated, when one of the two considered signals interfered the Base Station (BS) or the Costumer Premise Equipment (CPE). The experimental results point out that the continuous wave was more critical than the pulsed one for the WiMAX system; in some situation it caused the complete disconnection of the CPE from the BS or the BS outage

“…Measurement campaigns by several research groups, including [12], [13] and [7], illustrated that the fading in the offshore environment can be better predicted using the two-ray model. In this section, we propose a novel diversity approach which could counteract deep fading due to surface reflections.…”

From the perspective of several measurement campaigns in the offshore environment, it has been reported that the sea surface reflections are the main source of deep fading. We present a novel solution to this problem, by investigating the analytical implications of the propagation model which best fits the offshore channel characteristics. We also present a novel and yet simple implementation of receiver diversity which can mitigate the fading caused by sea surface reflections and ensure that the link is always steady even under extreme turbulent conditions.

“…Regarding above water maritime wireless communications, the works in the literature to provide cost-effective and high bit rate solutions so far have been based on WiMAX technology. Some examples are the buoy-to-ship point-to-point communications solution using the 5.8GHz band [10], the performance evaluation of ship-to-shore point-to-point communications [11], and the multi-hop ad-hoc routing protocol and cognitive medium access control mechanism for long range ship-to-shore communications [12]. Though WiMAX based solution is good, the capital expenditure (CAPEX) for WiMAX is high.…”

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.
