Power Line Communication - demonstration test bed
Jureková, Petra ; Fujdiak, Radek (referee) ; Mlýnek, Petr (advisor)
This thesis is focused on data communication through electrical power grid - PLC Power Line Communication (PLC). It describes PLC communication, its present possibilities and two main types of transmission - broadband and narrowband, which are compared in detail. Major topic is an impact of noise on PLC signal and effect of growing distance on transmission efficiency. Within that is processed the analysis of distance and noise influence. Practical part of the thesis contains many types of measurements focusing especially on broadband modems. Measurements were performed both in the home and in the laboratory environment. The results show the effect of the distance and interference on the network throughput and the spectral power of the PLC signal. The RFC2544 methodology was also used for measurements.

Narrowband data transmission over the power lines
Valenta, Jaroslav ; Mišurec, Jiří (referee) ; Mlýnek, Petr (advisor)
This bachelor´s thesis is focused on narrowband data transmission over power lines. At first are described possibilities of narrowband data transmission over power lines, next the type of noises and then thesis deals with parameters of communication channel. In this thesis are described too modulation, error corection and data encryption for reliable communication. In the last part of thesis are realized practical measuring in laboratory workplace. The influence of data communication on primary function of power lines are tested. In the end are realized measuring of noise influence on data communication.

Narrowband Power Line Communication with Yitran module
Chernikau, Ivan ; Sysel, Petr (referee) ; Mlýnek, Petr (advisor)
This bachelor’s thesis is focused on a narrowband data transmission over power lines. At first, possibilities of the narrowband data transmission over power lines were described. Then we focused on the properties of a narrowband modem Yitran IT700. A communication between modems was tested in different modes. Different dependences were measured (dependence of the data transmission speed on the distance, dependence of the error percentage on the distance and on the impedance). Experiments took place on the usual power lines at the Faculty of Electrical Engineering BUT in the building T12. Then an application for remote control of a relay through power lines on the base of PLC communication and Yitran modems was designed and implemented.
