SANSA project is organized in seven work packages (WPs) as illustrated in the following figure:
WP1-Project management: The aim of WP1 is to coordinate the whole project and consortium from both the administrative and technical point of views. It monitors and coordinates the activities carried out in the rest of WPs in order to ensure a successful execution of the project plan.
WP2-Scenario and requirements definition: WP2 studies the current regulation for terrestrial-satellite spectrum sharing in Ka band as well as the state of the art of current back haul technologies. Based on this it will determine the interfered scenarios and network architectures that will be used throughout the whole project. The Key Performance Indicators (KPIs) for evaluating the proposed solutions will be defined and their theoretical bounds will be analysed.
WP3-Terrestrial-Satellite shared spectrum: The objective of WP3 is to study the PHY and MAC layer technologies that enable the shared spectrum between terrestrial and satellite segments for an efficient spectrum usage. WP3 will investigate solutions at three different levels. First, it will focus on the design of smart antennas with beam- and null-steering capabilities for interference mitigation and network topology self-organization. Second, WP3 will develop Hybrid (Terrestrial-Satellite) dynamic radio resource management (RRM) techniques which will maximize the system availability and capacity, while assuring that the QoS of both satellite and terrestrial links are not degraded by spectrum coexistence. Finally, database-assisted access will be adressed. WP3 will provide solutions for storing in databases static and dynamic information of the interfering transceivers such as location, transmit power and temporal spectrum activities, and for using it to efficiently manage the shared access to the spectrum.
WP4-Hybrid-terrestrial satellite backhaul adaptive network: WP4 is focused on the study of the interoperability between terrestrial and satellite networks for a seamless integration and the definition of a Hybrid management architecture for efficiently controlling both terrestrial and satellite network resources. It will investigate novel self-organizing load-balancing routing algorithms capable of aggregating the capacity offered by all terrestrial and satellite resources available at each backhaul node resulting in an overall capacity increase. Energy aware routing algoritms will be also fully adressed in order to improve the global power consumption of the terrestrial segment.
WP5-Key enabling components: The outputs of theoretical studies carried out in WP3 and WP4 will be used in WP5 for implementing a prototype of the two key components of the SANSA solution: (i) a low cost antenna with beam and null-steering capabilities for interference mitigation and network reconfiguration (ii) a Hybrid network manager that will be the key component managing the resources of the Hybrid network.
WP6-Experimentation and demonstration: The key component prototypes developed in WP5 will be integrated in WP6 with Fraunhofer test facilities in order to perform a proof of concept demonstration of SANSA techniques. In particular, we will carry out an over-the–air demonstration of the shared spectrum between terrestrial and satellite segments enabled by the smart antennas and also a demonstration of the backhaul network capacity and resilience improvement enabled by the Hybrid network manager.
WP7-Exploitation plan and dissemination: WP7 main objective is to coordinate,promote and aid in exploiting SANSA results. To this end, WP7 will: (i) define the roadmap for bringing SANSA solutions closer to commercial exploitation; (ii) provide appropriate visibility of the project results to the relevant industrial and academic community; and (iii) positively contribute to related standardization and regulation bodies, as well as teother technological platforms.
