a transmitter configured to modulate and demodulate millimeter-wave radio-frequencies;

a processor; and

a memory comprising instructions that, when executed by the processor, cause the processor to perform operations comprising:

performing, by the transmitter operating in conjunction with the processor and the memory, beam forming processing with a millimeter-wave terminal located in at least one moving object;

detecting a beam angle from the beam forming processing based on a millimeter-wave terminal location and a location of the data transmitting device that is installed at a predetermined distance external from the at least one moving object;

estimating a position of the at least one moving object based on the beam angle and the location of the data transmitting device;

determining whether the estimated position of the at least one moving object is within a communication area of the data transmitting device for communication with suppressing radio frequency interference with another moving object; and

transmitting desired data to the at least one moving object through the transmitter if it is determined to be within the communication area,

wherein the beam forming processing is performed to provide a timeframe for the communication when the at least one moving object is moving.
