Presents the model and methodology, applied by ITU-R
WRC’07, to calculate the spectrum requirement
Spectrum Requirement Planning in Wireless Communications:
Model and Methodology for IMT-Advanced is
a self-contained ‘handbook’ of the models and
methodologies used for the spectrum requirement calculation for
IMT-Advanced systems, as well as for the predecessor IMT-2000
systems. The reader will learn how the spectrum requirement
is calculated for real systems that prevail worldwide. The book
also provides the basis on which to develop advanced methodologies
for yet future systems, as the spectrum regulation will continue in
the future.
Spectrum Requirement Planning in Wireless Communications:
Model and Methodology for IMT-Advanced
* Provides the reader with information on how the spectrum
requirement is calculated for real systems that prevail
worldwide
* Contains useful tables and examples such as flowchart of the
methodology
* Introduces definitions of service category and radio
environment, the process of distributing traffic to radio
environments, and the method to calculate the required
spectrum
* Applies queueing and loss models for the calculation of
required system capacity
* Covers utilization of radio frequencies, market data, spectrum
requirement calculation methods for IMT-2000 and for IMT-Advanced
systems
* Instructs how to use the calculation tool package
* Comes with an accompanying website with the downloadable tool
applied by ITU-R WRC’07 for making decisions on spectrum
regulation for mobile systems
This book serves as an invaluable guide to engineers in mobile
phone companies, system design engineers, operator system engineers
and other specialists dealing with mobile system planning and
development. It is also of great interest to researchers and
graduate students in the fields of applied probability theory,
operations research, telecommunications, and mobile networks
engineering.
