Wideband methods of data transmission over power networks
 Svoboda, Pavel ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
The aim of this work was to peruse and desribe the high-speed data technology communicating over energy network. In this work was investigated broadband system communicating over low power distribution network. The laboratory network was designed for measuring parametres of this communication and performed set of tests. Lended devices were described, properties of technology specification and methods of connection and management were introduced. Management, configuration and measuring over web interface on the NMS device was described and simple dividision into corresponding functional blocks corresponding to structure of web bookmaks was made. Metodology of individual tests, grounded on documentation “recomandation” RFC and on introduced works, was elaboratly described. Used tools, their properties and managements were described. The transmission speed on application and physical layer were followed primarily, frequency dependencies on signal noise ratio and bits per carrier were followed secondary. Measured results from individuals tests were compared among each other and evaulated. This observation leaded into decision on needed criteria for varius application. The suitaibility for integration into communication network for maintaining corresponding QoS was appreised. Testing and chosen types of tests in this project were standardized and integrated into ITU standard. Individual tests are able to compare from the view of their testify charactestic.
