Embodiment Construction

[0020] Examples of the specification are described below. It is important to note that all described embodiments below and their properties and technical features can be combined in any way, ie there is no limitation that some of the described embodiments, properties and technical features cannot be combined with each other.

[0021] exist figure 1 , a schematic block diagram of an apparatus 100 that can be used in a power line communication system is shown. The device 100 comprises a power input 101 for supplying external AC power to the device 100 via a power cable 102 connected to a mains power socket (not shown) connected to the mains power network or to a household Electricity network (household power lines), such as wall outlets in an apartment or single family house. It should be noted that for the term "power input terminal" any input terminal for supplying external AC power can be understood, such as an input terminal of a plug arranged outside the device and config...

Abstract

A device comprises a power input for supplying an external AC power to the device via a power cord, a filter for filtering noise from the outside out of the supplied external AC power and for thereby generating a filtered AC power, at least one power socket for supplying the filtered AC power to at least one other device, a PLC modem configured to be connected to the at least one power socket and to transmit data to or receive data from the at least one other device via power line communication using the filtered AC power, and a managing means configured 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. A respective power line communication system and a respective power line communication method are also proposed.

Description

technical field [0001] The present invention relates to a device usable in a power line communication system. The present invention further relates to a corresponding power line communication system and a power line communication method. Background technique [0002] Power line communication (PLC) is a term describing the method of using power distribution lines for simultaneous distribution of data, also known as mains communication, power line transmission (PLT), broadband power line (BPL), power strip or power line network (PLN). The carrier can communicate voice and data by superimposing analog signals on the standard 50Hz or 60Hz alternating current (AC) of the electrical network. For indoor applications, PLC devices can use household power lines as a transmission medium for data transfer. [0003] However, power line communication between devices in a power line communication system may be affected by other devices or systems located outside the power line communicat...
