Abstract:
1. A device comprising: power input circuitry configured to supply an external AC power to the device via a power supply line; filter circuitry configured to filter out noise from the supplied external AC power and to generate a filtered AC power; at least one power socket configured to supply the filtered AC power to at least one other device, external to the device, connected to the at least one power socket; a Power Line Communication (PLC) modem configured to be connected to the at least one power socket and to transmit data or receive data via the at least one power socket using power line communication and the filtered AC power; and managing circuitry configured, in a setup mode, to establish a data connection with the at least one other device and to detect whether the at least one other device is capable of PLC functionality, wherein the establishing the data connection with the at least one other device includes outputting a first signal to the at least one other device, the outputted first signal having one or more of a first transmission signal power, a first bandwidth and a first center frequency, each of which is respectively lower than a second transmission signal power, a second bandwidth, and a second center frequency of a second signal output by the managing circuitry in a PLC mode.
