A wireless conference system includes a master device and a slave device. The master device includes a master user interface, a master BLUETOOTH unit, a master memory unit, and a command converting unit. The master user interface includes a master screen. The master memory unit saves a conference document. The slave device includes a slave user interface, a slave BLUETOOTH unit, and an executing unit. The slave memory unit saves a copy of the conference document. Operation commands to operate the conference document are input through the master user interface. The command converting unit converts the operation commands to corresponding slave commands. The corresponding slave commands are transmitted to the slave device by the master BLUETOOTH unit and the slave BLUETOOTH unit. The executing unit executes the corresponding slave commands to operate the copy of the conference document.
