End-to-End Efficiency (E3) is aiming at integrating cognitive wireless systems in the Beyond 3G (B3G) world, evolving current and future heterogeneous wireless system infrastructures into an integrated, scalble and efficiently managed B3G cognitive system framework from a technical, regulatory, standardisation and business perspective.

Main Objectives

The key objective of the E3 project is to design, develop, prototype and showcase solutions for optimised usage of existing and future radio access resources. In particular, more flexible use of frequency spectrum, terminals, base stations and networks is addressed. E3 will provide interoperability, flexibility and scalability between existing legacy and future wireless systems, manage the overall system complexity, and ensure convergence across access technologies, business domains, regulatory domains and geographical regions. E3 will converge both cognitive radios and cognitive networks from technical, business, regulatory and standardisation perspectives.
