Abstract

MéTODOS PARA SUPORTAR INTERCONEXãO DE REDE DE DADOS EM UM SISTEMA DE RADIODIFUSãO E PARA HABILITAR UMA PLURALIDADE DE ESTAçõES SEM FIOS SECUNDáRIAS SE COMUNICAREM ENTRE SI EM UM SISTEMA DE COMUNICAçãO, MEIO LEGìVEL POR COMPUTADOR E TRANSCEPTOR. A presente invenção provê métodos e aparelhos para utilizar porções não usadas de um espectro de freqüência alocado em um sistema de comunicação sem fios que radiodifunde conteúdo para estações sem fios. Uma primeira estação sem fios pode se comunicar com uma segunda estação sem fios em um canal radiodifundido inativo enquanto mantendo o nível de interferência resultante abaixo de um limite máximo aceitável nas outras estações sem fios. Usando informação de nível de interferência que é medida nas estações sem fios, a estação sem fios pode negociar com a outra estação sem fios em um canal de estabelecimento para comunicação subseqüente em um ou mais canais radiodifundidos. A estação sem fios pode receber conteúdo radiodifundido em um intervalo de tempo que corresponde a um canal radiodifundido e que é ademais processado pela estação sem fios. Caso contrario, a estação sem fios pode utilizar o tempo correspondente para medir um nível de interferência para o canal correspondente ou para transmitir ou receber dados para/de outra estação sem fios.
