Summary

This book provides a thorough treatment of the model and methodology used for the spectrum requirement calculation for the IMT-Advanced systems and the previous IMT-2000 systems. It presents the reader with information on how the spectrum requirement is calculated for real systems which prevail worldwide and serves as a basis for developing the further advanced methodology for yet future systems. Contains practical tables and examples such as flowchart of the methodology, definition of service category, definition of radio environment, process of distribution traffic and required spectrum calculation, calculation of required system capacity, reservation based traffic model and many more Covers Utilization of Radio Frequencies, Spectrum Requirement Calculation for IMT-2000, Spectrum Requirement Calculation for IMT-Advanced, Calculation Tool Package, Market Data, Radio Characteristics etc Comes with an accompanying website with the downloadable methodology tool The contributors to the book are members of Mobile IT Forum in Japan and the WINNER project group in Europe who developed the new methodology as Working Party 8F of the ITU-R.
