A millimeter-wave ground station (101) corresponding to a data transmitting device performs beam forming processing with a millimeter-wave on-board station (103) corresponding to a terminal provided in a car (300), detects a beam angle based on a result of the beam forming processing, estimates a position of the car (300) based on the detected beam angle and installation position information of the millimeter-wave ground station (101), and transmits content data in a spot manner to the car (300) whose position is estimated. When transmitting the content data, the content data is fragmented pursuant to an allowable transmission unit as necessary. Further, transmission of the content data is performed using millimeter waves.
