Unidirectional control system which is used in watching any defect and electric leakage as a monitoring system of street light on the road is required to use FM radio, but in the other hand, bidirectional control system needs CDMA, which makes possible using not only remote control of street light switch but also remote real-time inspection for any defect, short circuit, and on/off status. Especially, operators can get a text massage into his mobile phone from the system in case of emergency. This consists of central regulation system, bidirectional switch, and collateral equipment.
Central Control System
