However, there is lack of published literature with results from actual test¬beds. This paper introduces the work done in the EU Sixth Framework Programme Project WEIRD to design and set up WiMAX testbeds in four EU countries. We describe the method¬ology followed, detail our implementation and present results from the testbeds, as deployed in the first phase of WEIRD. The testbeds are used to demonstrate how WiMAX technology can be used to extend the connectivity of the pan-European data com¬munications network (GEANT2) to isolated and impervious ar¬eas and, furthermore, to assure end-to-end quality of service to novel applications.172 1004 - PublicationOpen AccessUsing wireless point-to-point connections to improve volcano monitoring: a feasibility study of the WiMAX technology applied to the Campi Flegrei volcanic area (Southern Italy)(2009-06-11)

Commonly known as Universal WiMAX (worldwide inter-operability for microwave access), this access technology reaches a high bit rate and covers large areas with a single base station, making it possible to offer connectivity to end users in a cost-effective way. A further useful property of the WiMAX technology is that the transmission can be used both in line-of-sight (LOS) and non-line-of-sight (NLOS) environments, allowing highly feasible communications (WiMAX Forum 2004). Thanks to these features, IEEE 802.16 opens the way to the use of wireless technologies in the environmental monitoring of areas such as seismic and volcanic zones.324 20 - PublicationOpen AccessUsing WiMAX technology to improve volcano monitoring: the WEIRD System(2007-11-13)

This access technology allows reaching high bit rate and covering large areas with a single Base Station (BS). Thanks to these features, IEEE 802.16 opens the way for the use and the introduction of wireless technologies in particular emergency scenarios, like volcano monitoring. Active volcano surveillance is based prevalently on the analysis of geophysical and geochemical parameters gathered by monitoring networks. Of all, seismology is one of the most useful methods for volcano monitoring. In fact, several types of seismic signals, e.g. volcano-tectonic earthquakes (VT), long-period events (LP), volcanic tremor, can occur before and during an eruption. The analysis and interpretation of these seismic signals are a very important task for the volcanic eruption forecasting (Scarpa and Tilling, 1996). WiMAX technology can be applied to provide broadband wireless access in volcano monitoring scenarios, in order to solve all the problems that today limit the possibility to realize a real-time and accurate monitoring of volcanoes activities in emergency situations. In particular, this paper focus on a novel solution, designed within the IST FP6 EU WEIRD (WiMAX Extension to Isolated Research Data networks) Integrated Project, to perform volcano monitoring using the features offered by IEEE 802.16 networks in order to improve transmission of data acquired by temporary seismic stations deployed during emergencies. Tests performed on field demonstrate the advantages offered by the use of WiMAX compared with other commonly used technologies.155 229
