Abstract

trata-se de um sistema de antena distribuída e backhaul que fornece conectividade de rede para uma implantação de célula pequena. em vez de construir estruturas novas e instalar fibras e cabos adicionais, as modalidades descritas no presente documento revelam a utilização de comunicações de onda milimétrica de alta largura de banda. um sistema de onda milimétrica de sobrecarga pode ser utilizado para fornecer conectividade de backhaul. os módulos podem ser colocados em infraestrutura existente, como iluminações públicas e postes de eletricidade, e os módulos podem conter estações de base e antenas para transmitir as ondas milimétricas para e a partir de outros módulos. os sinais de enlace ascendente e enlace descendente (isto é, sinais direcionados para/a partir de uma estação de base a partir de/para um nó de comunicação) podem ser divididos de modo espectral em canais de controle, segmentos espectrais de enlace ascendente/enlace descendente, em que cada um inclui sinais modulados que podem ser convertidos em frequência para sua banda de frequência original/nativa para habilitar os nós de comunicação para se comunicar com um ou mais dispositivos móveis ou estacionários, e sinais piloto que podem ser providos com alguns ou todos os segmentos espectrais para mitigar a distorção criada entre os nós de comunicação. os sinais piloto podem ser processados por transceptores de nós de comunicação a montante ou a jusante para remover a distorção de um sinal de recebimento (por exemplo, distorção de fase).
