Abstract

<B>"APARELHO E MéTODO PARA REUTILIZAR ESPECTRO DE RADIODIFUSãO DE SATéLITE PARA SINAIS TERRESTRES DE RADIODIFUSãO"<D>. Uma antena de recepção de satélite (16) em uma localização de usuário (14) recebe sinais de satélite em uma primeira freq³ência vindos de um satélite (12). Os sinais de satélite percorrem ao longo de uma rota de sinal de satélite (42) dentro de um ângulo de visão ao redor da linha central (28) da antena (16). Um transmissor terrestre (20) transmite sinais na primeira freq³ência ao longo de uma rota de transmissão sem fio (40) a partir do transmissor para a localização de usuário (14). O transmissor terrestre (20) é localizado, com relação à localização de usuário (14), de modo que a rota de transmissão sem fio (40) fica em um ângulo relativamente grande com relação à linha central (28) da primeira antena (16). O ângulo da rota de transmissão sem fio (40) à linha central (28) da antena de satélite é grande o suficiente para que os sinais terrestres presentes na localização (14) resultem em sinais de entrada terrestre vindos da antena (16), os quais são inferiores a um nível de interferência com relação aos sinais de entrada de satélite produzidos pela antena. Assim sendo, os sinais terrestres não interferem com os sinais de satélite mesmo apesar de eles serem transmitidos em uma freq³ência comum.
