Abstract: Disclosed are a mobile terminal capable of positioning, a positioning server, and a positioning method for the mobile terminal using the same. The disclosed positioning server includes: a control unit which controls transmission of visible ray signals from a plurality of visible ray transmitting devices; and a position calculation unit which calculates the position of the mobile terminal based on reception time data of the visible ray signals transmitted from each of the visible ray transmitting devices. The control unit controls the visible ray transmitting devices to consecutively transmit visible ray signals for a first time interval while not allowing the transmitting points of time of the visible ray signals from each visible ray transmitting device to be overlapped. The reception time data of the visible ray signals to the mobile terminal includes data at a certain point of time included in a time section when a visible ray signal of which the reception intensity is equal to or greater than a preset threshold value is received. [Reference numerals] (AA) Reception intensity; (BB) Protection time section (visible ray transceiving device a); (CC,GG) First reception time section; (DD,HH) Second reception time section; (EE) Reception time section (visible ray transceiving device a); (FF) Protection time section (visible ray transceiving device b); (II) Reception time section (visible ray transceiving device b); (JJ) Threshold value; (KK) Time (sampling index)

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.
