Abstract

"MéTODO E APARELHO PARA DETECTAR A PRESENçA DE UM SINAL EM UM DE PELO MENOS DOIS CANAIS DE FREQUêNCIA EM UM REPETIDOR DE TRANSLAçãO DE FREQuêNCIA PARA USO EM UMA REDE DE áREA LOCAL SEM FIOS (WLAN)". Um repetidor de translação de freq³ência (200) para uso em um sistema de comunicação de protocolo de rádio dúplex por divisão de tempo inclui uma característica de controle de ganho automático. Detecção é executada por comparadores (401, 411), ADCs (402, 412), DACs (404, 414) e um processador (315). Detecção pode ser anulada por processador (315) usando elementos lógicos (406, 416, 407 e 417) para controlar a geração de um sinal de Canal A/Canal B e um sinal de PA_ON para controlar um amplificador de potência associado com o transmissor.
BR0316218-4A 2002-11-15 2003-11-17 Método e aparelho para detectar a presença de um sinal em um de pelo menos dois canais de frequência em um repetidor de translação de frequência para uso em uma rede de área local sem fios (wlan) BR0316218A (pt)
