Abstract

"SISTEMA E MéTODO PARA OTIMIZAR TRANSMISSõES BLUETOOTH PARA SUPERAR INTERFERêNCIA DE SINAL". As transmissões de um dispositivo Bluetooth (102) são otimizadas para superar a interferência de sinal. As regra de mapeamento (125) ditam diferentes tipos de pacote Bluetooth a serem utilizados para a transmissão sob várias condições especificadas incluindo características de interferência de sinal prescritas. O dispositivo Bluetooth mede as características de interferência de sinal (112) sobre diferentes freq³ências Bluetooth. O dispositivo Bluetooth identifica as mensagens pendentes para transmissão (114a) para um ou mais dispositivos Bluetooth (104), e recebe a designação das freq³ências a serem utilizadas na transmissão das mensagens pendentes para o dispositivo Bluetooth remoto de acordo com um esquema de salto em freq³ências predeterminado (116a). O dispositivo Bluetooth aplica as regras de mapeamento às condições incluindo pelo menos as características de interferência de sinal medidas para as freq³ências designadas para selecionar os tipos de pacote Bluetooth para uso na transmissão de mensagens identificadas para o dispositivo Bluetooth remoto (figura 1).
