PURPOSE: An effective region supplying device capable of processing a wireless signal is provided to prevent a range of an effective region from being varied, and to control a vehicle speed and a driving direction according to road states. CONSTITUTION: The first signal generator(100) is installed on roads of the first end points(A1,A3) of effective regions(P1, P2) in order to automatically control a vehicle as a necessary driving state. The first signal generator(100) generates a current notifying that the vehicle is in the first end points(A1,A3) of the effective regions(P1,P2). The second signal generator(200) is installed on roads of the second end points(A2,A4) of the effective regions(P1,P2), and generates a current notifying that the vehicle is in the second end points(A2,A4). The first beacon(300) is installed between the first and the second signal generator(100,200), and transmits a wireless data signal for driving information to the points(A1,A2,A3,A4) installed in the first and the second signal generator(100,200).
