ANATEL 2013

What are the opportunities and challenges for efficient and optimized spectrum management in light of the need to expand telecommunications services to less populated areas, the digitization of free-to-air TV, and the growth of data consumption? These and other questions were debated at the 2nd Spectrum Management Seminar – A Vision of the Future, promoted by Anatel on September 17 and 18, 2013, at the Renato Guerreiro Cultural Space at the Agency’s headquarters in Brasília.

Sponsored by SINDISAT, UNION prepared a study on the coexistence in the C-band between satellite systems and terrestrial mobile communication applications, presenting the results at the seminar organized by ANATEL. The study—Interference of Terrestrial Mobile Systems on Satellite Applications: Concept, Characterization, Interference Studies, and the Real Need for Spectral Sharing—demonstrates the technical difficulty of this coexistence and questions its actual necessity. It points out that additional spectrum potentially yields a 3x increase in cellular system capacity, whereas efficient spectrum use accounts for a 6x increase, and—most importantly—increasing spatial efficiency (i.e., small cells) yields a 56x increase.
