This Recommendation describes a methodology for the calculation of terrestrial spectrum requirement estimation for the future development of IMT-2000 and systems beyond IMT-2000. It provides a systematic approach that incorporates service categories (a combination of service type and traffic class), service environments (a combination of service usage pattern and teledensity), radio environments, market data analysis and traffic estimation by using these categories and environments, traffic distribution among radio access technique groups (RATGs), required system capacity calculation and resultant spectrum requirement determination. The methodology is applicable to both circuit switched and packet switch-based traffic and can accommodate multiple services.
