Abstract
A portable radio telephone system includes a small and light radio telephone device and a charger for charging a storage battery in the radio telephone device. The charger has a connector for connection to a data communication device. A data signal received by a radio circuit and converted by a baseband circuit in the radio telephone device is supplied to a data interface, which superpose the data signal on charging electric energy. The data signal is then supplied through charging terminals of the radio telephone device and charging terminals of the charger. In the charger, the data signal is converted by a data interface into a signal for transmission through the connector to the data communication device.
