Abstract

"APARELHO PARA FACILITAR A COMUNICAçãO SEM FIOS EM UMA REDE ENTRE UM PRIMEIRO DISPOSITIVO DE COMUNICAçãO E UM SEGUNDO DISPOSITIVO DE COMUNICAçãO, REDE DE áREA LOCAL SEM FIOS, REPETIDOR PARA UMA REDE INCLUINDO PELO MENOS PRIMEIRA E SEGUNDA FREQuêNCIAS DE COMUNICAçãO BIDIRECIONAIS, REDE OPERANDO EM PELO MENOS PRIMEIRA E SEGUNDA FREQuêNCIAS DE COMUNICAçãO BIDIRECIONAIS, DISPOSITIVO DE EXTENSãO DE COBERTURA SEM FIOS, E, MéTODO PARA RETRANSMITIR UM SINAL DETECTADO COM AMPLIFICAçãO E/OU CONVERSãO DE FREQuêNCIA EM UM DISPOSITIVO DE COMUNICAçãO SEM FIOS". Um repetidor (200) facilita a comunicação sem fios entre um primeiro dispositivo de comunicação (100) e um segundo dispositivo de comunicação (105) em uma rede sem fios usando um protocolo de dúplex por divisão de tempo para transmissão de dados. O repetidor (200) inclui um receptor (310, 315) para receber um sinal em qualquer uma de pelo menos duas freq³ências de comunicação bidirecionais simultaneamente. Um detector de sinal (362) está acoplado operativamente ao receptor (300, 310, 315) para determinar se o sinal está presente em pelo menos uma das duas freq³ências bidirecionais. Um conversor de freq³ência (320, 321, 323, 324, 360, 361) é para converter o sinal presente em uma das freq³ências bidirecionais a um sinal convertido na outra das freq³ências bidirecionais. Um transmissor (300, 3259 330, 335, 345, 350) é para transmitir o sinal convertido na outra das ditas freq³ências bidirecionais.
