Modeling of Medium Access Methods of Power Line Communication
Koutný, Martin ; Orgoň,, Miloš (referee) ; Pospíchal, Ladislav (referee) ; Mišurec, Jiří (advisor)
The dissertation thesis is focused on analysis, modeling and optimization of the medium access layer of power line communication. In the first part of the paper, the thesis briefly summarizes a basic information of power line communication. In the next sections, the objectives of the dissertation are placed. A simplification of current models of HomePlug and a optimalization of distribution function in back off procedure are one of the main goals of this work. A detailed analysis of HomePlug technology, which is widespread used in the broadband transmission, follows. The work is focused on analyzing of the MAC layer in this part. The discrete simulation models have been implemented in Matlab. The approximation discrete numerical model has been used for analysis of various distribution functions for HomePlug to optimalize backoff algorithm. The new optimalizations are suitable for large networks. The new approach of MAC modelling is introduced in last part of this work. The new model is not exact as Markov models but it is faster and easier for implementation. The analytical model desribes a system using probabilistic functions.

Smart modul integrated in power plug
Rusz, Martin ; Musil, Petr (referee) ; Mlýnek, Petr (advisor)
The aim of this work is focus on Powerline Communication technology and select a suitable type of broadband integrated circuit for the integration of a broadband communication module into an electrical installation box. In the introduction of this work, the Powerline Communication technology, the principle of communication, individual types of technology, factors influencing the quality of transmission, current possibilities and setting goals necessary for the design of the module are analyzed in detail. The result is a miniaturized functional prototype of a fully integrated broadband PLC modem in a wiring box.

Comparison of HomePlug broadband systems and DS2 technology PLC
Horáček, Lukáš ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
This thesis comparing broadband systems HomePlug and DS2 PLC technology (Power Line Communications). PLC is a technology for transmitting data over electrical power distribution network. The theoretical part consists of describing a system for broadband data communication over high-tension lines, the selection criteria, a description of DS2 and HomePlug (variants of chips, version, network architecture, elements). There are also described modulation techniques, interference, standards, standard ISO 50065 and access methods. The practical part consists of laboratory measurements with both systems. For the testing were used DS2 modems from the company Defidev and HomePlug modems from AirLive. These are then compared according to selected criteria.

Broadband Plc Modul Integrated In Power Plug
Rusz, Martin
The main objective of this project is to design a functional prototype of an integrated broadband PLC module mounted in a power plug. The advantage of this device is the possibility of using PLC over the power distribution network for communication in the local home or company network and other application, without the need to connect additional equipment to the power plug.
