Protection Criteria for Different Radiocommunication Systems
Anatel’s Regulatory Agenda • 58 regulatory projects to be initiated or approved by the end of 2018 • 20 of them related to Spectrum Management, including: – Bands for IMT • 1.5 GHz; 2.3 GHz; 3.5 GHz • LAA (5 GHz) – PDFF (NTFA) – 39.5 – 40 GHz (accordingly determination of Resolution nr. 688/2017) – Evaluation of the need to review, update and unify the technical regulations of the broadcasting services (AM, FM and TV), within the premises of consistency and regulatory quality. Regulatory Impact Analysis by 2nd / 2018. – Regulation for dynamically access the spectrum in the VHF and UHF bands. Regulatory Impact Analysis by 2 nd half / 2018. – Spectrum Pricing, including associated with Satellites
Final Comments • Spectrum deals with past, present and future • We need a stable and predictable regulatory environment to: Facilitate the deployment of new technologies, Improve service quality, Country development. • We should not overprotect incumbent services; • Development of technical skills; • Harmonization and economy of scale; • Keep an open and frank dialogue with all players.
