This book addresses current technology trends and requirements leading towards the next era in
mobile communication handsets and beyond that the book proposes innovative solutions that
could be candidate solutions for 5G phones. It adopts a multidisciplinary and interdisciplinary
stance towards handset design a necessary ingredient if 5th Generation handset and services
are to really take-off. Therefore the scope of the book targets a broad range of subjects
including energy efficiency RF design cooperation context-aware systems roaming and
short-range networking all of which working in synergy to provide seamless mobility and high
speed connectivity within a HetNet environment.Specifically the authors investigate how we can
exploit the cooperation paradigm and context-aware mechanism working in synergy to provide
energy compliant phones that can introduce power savings of up to 50% on state-of-the-art.
Going beyond this a chapter on business modeling approaches is also included based on
incentive mechanisms for cooperation that will provide the necessary leverage to promote the
up-take of the proposed technology.
