Abstract

A semiconductor device includes a communication unit which receives a frame at a first transmission period, demodulates control information from a received frame, modulates transmission data, and broadcasts a modulated transmission data at a second transmission period as a radio frequency packet signal, a period determination unit which determines the second transmission period based on vehicle information, and a transmission and reception control unit which generates a transmission timing trigger signal for determining a transmission timing of the transmission data based on the control information and the second transmission period, and outputs the transmission data to the communication unit in synchronization with the transmission timing trigger signal. The second transmission period is equal to or longer than the first transmission period.
