Power Line Communication is a technology that enables the transmission of data signals over existing power lines, allowing electrical wiring to serve a dual purpose: delivering power and enabling data communication. It is widely used in both residential and industrial settings to create communication networks without the need for additional dedicated wiring. Proposed technology can be a highly effective for the systems with limited physical access, or even for the already built systems modernization. This paper describes the modified physical layer inside of the PLC networks.

This paper describes an electronic communication method based on the use of the DC-DC converter as a data transfer device. Output voltage of a DC-DC converter is modulated with Amplitude-Shift Keying (ASK) signal carrier. Modulation takes place in the feedback loop of the DC-DC converter. The output signal passes through the transition line to the band pass filter, where unexpected noise and DC components are removed. Transition line is represented as a long wire with a certain length that contains active and reactive parasitic parameters.

Marketing of enterprises is becoming an increasingly important component of their effective ac- tivities, however, with the development of technology, traditional ways of promoting goods are gradu- ally losing their effectiveness, because most people no longer trust advertising.

Problem setting. In democracies, the inherent right of citizens is the right to be informed about the policy pursued by the state, including not only the publicity and openness of government, but also the right to communicate public opinion on socially important issues to the government.
