  1. 1. www.gvf.org Interferencia em Estações Terrenas O Preço do Sucesso... E o que a Industria está fazendo sobre Isto Cristovam Nascimento Director, Brasil GVF
  2. 2. www.gvf.org Por que a Interferencia está Aumentando ? Custo dos Terminais Pagamento aos Instaladores Quantidade Instalada Por Ano SFD - Sensibilidade dos Transponders Resultante
  3. 3. www.gvf.org Interferencia de RF: “Fazendo Baixar” ! • Problemas: 1. Portadoras Não Identificadas 2. Instalações “Impróprias” 3. Equipamento “Abaixo do Padrão” 4. Interferencia de Redes Wireless 5. Insuficiente Coordinação de Incidentes • Soluções:  Carrier ID  Treinamento & Certificação  Type Approvals  Spectrum Initiative  Centro de Compartilhamento de Dados
  4. 4. www.gvf.org Characterizing Interference Types Interference Types 6 Month Average 8% 47% 33% 7% 3% 2% 0% Adjacent Satellite Interference Unauthorized Carrier Cross-Pol/Copol Sweeeper Retransmit/FM Rebroadcast Transponder Compression All Others Note: Percentages are based on Intelsat's experience but are indicative of hundreds of interference events experienced by the world’s satellite operators.
