The project intends to reduce the use of resources in the form of cables in trucks by allowing data transfer over existing electrical wiring. It presented a theoretical model of a modem, intended for communication via phase modulation over power lines. The model consists of few components and communication method is full duplex. The model offers the possibility and the opportunity for channel selection in software. From the model a transmitter module, receiver module, voltage regulator and a separate quadrature detector is constructed. Initial tests and checking which were done on these four components showed first that the data transfer between the transmitter module and receiver module worked but the transmission was unreliable, meanwhile the voltage regulator and the external quadrature detector worked and delivered the expected performance. The model is eligible for further possible development and practical implementation.
