Abstract: A transceiver device operatively coupleable with a protection and control device to provide wireless connectivity to the protection and control device. The transceiver device includes: a transceiver unit including an RF antenna; a serial communication port operatively coupleable with a further corresponding serial communication port of the protection and control device; a serial communication bus electrically connected between the serial communication port and the transceiver unit and having a transmission line and a reception line, in operation the transmission line taking a high-level voltage value, when the transmission line is in a stand-by condition, and a low-level voltage value, when the transmission line is in an active condition; a battery unit; and a feeding unit to feed the transceiver unit with a feeding voltage, the feeding unit including a first power supply stage electrically connected with the battery unit to harvest electric power from the battery unit and a second power supply stage electrically connected with the transmission line of the serial communication bus to harvest electric power from the transmission line, when the transmission line is in stand-by condition and takes a high-level voltage value.
