    Abstract: PURPOSE: A device and method for changing the light-emission angle of an optical transmitter in a visible light wireless communications system are provided to enable the light-emission angle of the optical transmitter to be changeable. CONSTITUTION: A reception part (601) receives signal reception strength of signal-to-noise ratio (SNR) information, which is transmitted from an optical receiver and measured at each of multiple optical transmitters, and the SNR information from the multiple optical transmitters. A determination part (603) determines whether the SNR information is bigger than a predetermined threshold value. If the SNR information is smaller than the threshold value, a control part (605) changes the light-emission angle of at least one among the multiple optical transmitters by using the signal reception strength.
