Abstract

"PREVENçãO DE OSCILAçãO DE REPETIDORA". São revelados um método e equipamento para detectar oscilação em um sistema de repetidora. Mais especificamente, em uma modalidade, um dispositivo de comunicação sem fio é incorporado em um sistema de repetidora e é configurado para detectar se o sistema de repetidora está em oscilação. Um processador acoplado ao WCD é configurado para reduzir o ganho do sistema de repetidora se o sistema de repetidora estiver em oscilação.
