“…This is the goal of the "W-band Analysis and VErification" (WAVE) program (2004-on going) of the Italian Space Agency (ASI), that aims at the exploitation of the W-band (75-110 GHz range) for broadband satellite communications [11,12]. The program is undertaken by a large team of aerospace industries and scientific institutions.…”
Section: Examples Of Integration Scenariosmentioning
Integration and convergence of different access technology is a key concept of 4G systems. This integration also includes the interface among terrestrial and aero-space components, whose importance has been so far under-estimated and not deeply understood. In this paper, a layered model of the 4G integrated network vision is introduced, highlighting details about the aero-space component. The concept of integration is discussed under different viewpoints, particularly highlighing integration among aero-space segments and related services (i.e. navigation). Examples of integration scenarios identified and investigated in the frame of research programs co-funded by Italian institutions are also displayed in the paper.

“…This network can be split into two different subnetworks based on their coverage features: a long-range network (LRN) and a short-range network (also called incident area network, IAN). The LRN comprises Geostationary Earth Orbit (GEO) and Low Earth Orbit (LEO) satellites and HAP systems that enable communication between the incident area and the external zones [7]- [9], while the IAN is a self-forming temporary ad hoc network deployed on the scene of an incident to replace the damaged network infrastructure and is able to support personal and local communications among different public safety end users. In the following, possible cooperative solutions for both hybrid satellite terrestrial systems and high altitude platforms -mobile ad hoc network (HAP -MANET) networks are defined and studied and the behavior of coexisting air interfaces in the IAN is analyzed.…”

“…The received signals will provide the necessary elements to analyze the channel behavior at different weather conditions and thus providing a solid base for the later W-band satellite channel exploitation [4].…”

confidence: 99%
“…Italy has proven a remarkable experience in the exploration of high frequency ranges in satellite communications where many efforts have been recently dedicated in conceiving and bringing the two ASI (Italian Space Agency) scientific satellite projects in W-band, DAVID [1] [2] (DAta and Video Interactive Distribution) and WAVE [3] [4] to an advanced definition phase.…”
In this paper 1,2 , an overview of the evolution towards the second phase (A2) of the WAVE (W-band Analysis and VErification) project is made, and the timeline for the development of a future pre-operative space mission is defined. This includes the definition of a number of advanced preliminary W-band applications such as the utilization of the M-55 Geophysica manned stratospheric aircraft for a number of experiments on the channel propagation in W-band 94 GHz and 82 GHz; the introduction of the LEO nano-satellite mission IKNOW (Inorbit Key-test and validatioN Of W-band) which will be used for a first uplink-downlink satellite channel characterization and in-orbit validation of W-band technology and space qualification processes. These applications are expected to provide the necessary elements towards the realization of the GEO pre-operative payload defined in the phase-A of the project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
