RESUMO

In this work a new method for the assessment of the spectrum use efficiency is proposed to be applied to point-area, including broadcasting, and point-to-point telecommunications systems. The proposed definition of the efficiency index is based in technical aspects, but other subjects that affect the determination of a telecommunications system efficiency, as economics, social, political and strategic issues are also discussed. The method is tested with data of real systems available from the Brazilian Regulatory Agency (Anatel) and at the telecommunications service providers web sites. It is very important to assess the telecommunications systems efficiency, because being the radio spectrum a scarce resource, limited by technology and management capacity, the introduction of new telecommunications services will only be possible by replacement, refarming or suppression of some less efficient applications. Despite national and international regulations usually refers to the importance of efficient use of the frequency bands, there is no harmonized assessment method to be applied and verified by the regulators. The new technologies and the opportunities for social development provided by them, bring to the light the need for a good radio spectrum management and how each part of it must be used efficiently and assigned properly for each type of application or telecommunications service.
