Power-line data communication
 Šádek, Michal ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
This master's thesis describes a principle of the systems for data communication over powerline. The frequency we can divide to narrowband and broadband. Various modulatory techniques with their usage and access method technology according to norms are mentioned. Engineering constraints as are frequency subband and sources disturbance are mentioned. A conception laboratory net is designed, where are effected trial measurement in data communications for systems ModemTec, Homeplug AV a DS2. This demonstration of communication contains display communications spectrum of choice systems and their matching. To comparison is used synthetic created nets LISN (Line Impedance Stabilizing Network) in narrowband transmissions. Long - term metering of systems ModemTec is is effected in laboratory net VUT and in the working condition in Swiss extension companies Daetwyler Rubber where are produced robust rubbery production. System DS2 is measured in home network, where are supposes low disturbance and in industrial environment company Daetwyler Rubber. On the basis report information of phase quality recorder a powerline and measured rate of communication, it is evaluate an influence disturbance on a data transmission and response time. At the close are mentioned principles of usage this communication.
