Cognitive Radio and Dynamic Spectrum Access 

Cognitive Radio for Dynamic Spectrum Access gives a
comprehensive overview of the main concepts behind radio spectrum
regulation, dynamic spectrum access and cognitive radio. Spectrum
measurements are introduced to illustrate the inefficiencies in
today’s spectrum usage and the book also discusses enablers
for horizontal and vertical spectrum sharing. Among others a
game-theory-based approach for spectrum sharing is described and
evaluated. Institution and standardisation approaches in academic
research and industry are highlighted including IEEE SCC41,
802.11k/n/s/y and 802.22 which lead towards commercial exploitation
of cognitive radio. In conclusion, this book looks at the initial
steps towards the vision of true cognitive radio and the potential
impact on telecommunication business.

* Introduces the benefits and challenges of cognitive radio

* Presents cognitive radio in research and industry and covers
implications for operators from the perspective of a telecom
operator

* Examines how cognitive radio techniques will considerably
change the wireless communication market.

About the author

Lars Berlemann and Stefan Mangold both contribute to research
programs, standardization and industry innovations in the field of
dynamic spectrum access, cognitive radio, and IEEE 802 standards.
Together they have filed numerous journal and magazine articles,
patents, and contributions to research conferences and workshops.
They both consult government organizations such as the European
Commission in steering related research programs.

Lars Berlemann and Stefan Mangold have been delivering tutorials
on cognitive radio at various research conferences such as IEEE
PIMRC and the European Wireless Conference. As alumni from RWTH
Aachen University, Germany, Lars Berlemann and Stefan Mangold
graduated at the Chair of Communication Networks, Com Nets, with
Professor Bernhard H. Walke as Ph D advisor. Their Ph D theses (both
awarded summa cum laude) are today considered to be
important early research contributions to the field and are in the
highest ranks in the number of downloads from the
University’s download servers. Together with Professor Walke,
Drs Berlemann and Mangold coedited the Wiley book IEEE 802
Wireless Systems: Protocols, Multi-Hop Mesh/Relaying, Performance
and Spectrum Coexistence which was published in November
2006.

Lars Berlemann is product manager in the product and innovation
department of Deutsche Telekom, Germany. Stefan Mangold is manager
at Swisscom, Switzerland, leading the access team of the product IT
development group of Swisscom Network & IT. They both work for
companies that operate mobile, fixed, and broadcast networks, and
in addition provide services with excellent customer focus.
Consequently, Drs Berlemann and Mangold understand and exploit the
synergies between academic research focusing on excellence, and
industry innovations focusing on commercial exploitation.

Lars Berlemann and Stefan Mangold share and disseminate what
they learn. In parallel with their employment, they enjoy working
with students. Lars Berlemann is guest lecturer at the Chair of
Communication Networks, Technical University of Dortmund, Germany.
Stefan Mangold is with ETH Zurich, Switzerland, Department of
Computer Science, where he works as lecturer and visiting
scientist. In addition to his scientific engineering background,
Lars Berlemann holds a diploma in Business and Economics from RWTH
Aachen. The comments and statements made in this book are from the
