The key challenge of the wireless industry is to develop a system concept that can provide affordable, true broadband access for a variety of services under various business and regulatory regimes. It has been shown that making more spectrum available is a key tool to radically lower the cost of access and services. Current regulatory mechanisms for spectrum management have failed to provide significant portions of new spectrum and have not been very well adapted to the rapid pace of the development of technical systems. Today’s and emerging technologies, however, allow for the use of alternative spectrum management regimes involving rapid and more Dynamic Spectrum Access (DSA). The challenge addressed in this project is finding technical and regulatory schemes that can significantly increase the amount of spectrum for use in future mobile/wireless systems through the use of spectrum sharing etiquettes as well as market based approaches for spectrum allocation.

Although there is a considerable literature regarding DSA, most approaches for future systems have severe shortcomings when it comes to practical implementation. Schemes that are feasible in terms of scalability, fast convergence (real-time) and business appropriateness (e.g from an operator perspective), are still to be developed. In this project, we aim at developing detailed technical mechanisms for DSA considering both the heterogeneous environments described above as well as future business models in cooperative or competitive multi-operator scenarios.

The results are disseminated in the form of scientific publications as well as public workshops. Results are expected to (through project partner activities in FP7 and ITU) have direct impact on future spectrum regulation as well as systems standardization
