Smart Metering system
Gregor, Filip ; Pokorný, Jiří (referee) ; Mlýnek, Petr (advisor)
The thesis deals with a PLC technology. In the theoretical part a principle of PLC functionality and its advantages and disadvantages were described. In the experimental part methodology of point-to-point testing with BPL modems was designed. In addition extensive measurement according to point-to-point methodology for topology with and without repeater in laboratory was realized. Impact of repeater on transmission parameters was tested according to RCF 2544, RFC 6349 recommendation and according to methodology of TCP Throughput with the aid of Net Blazer testers and iPerf tool. The results shows that topology with repeater decreases throughput approximately 50 % and increases Round trip time (RTT) more than twice compared to topology without repeater. In the last part a laboratory task with Smart Metering system and BPL modems was designed.

BPL modem
Chromý, David ; Mlýnek, Petr (referee) ; Musil, Petr (advisor)
This work deals with the issue of PLC with a focus on BPL technology (Broadbandover-power lines), which is explained in the theoretical part. The work describes in detailthe main components for PCB design with manufacturing and mounting process. Fur-thermore, the thesis provides instructions on how to establish communication betweenBPL modems and a description of individual functions. In conclusion, the procedureof measuring the noise intensity in the 230 V power line is described with the results.The output of the diploma thesis is the selection of components and the implementationof printed circuit boards for two BPL modems. These modems allow to measure SNR(signal to noise ratio) at physical speed.

Broadband over powerline modem
Mahút, Michal ; Šilhavý, Pavel (referee) ; Musil, Petr (advisor)
The aim of the diploma thesis is to look into the issues of Broadband Over Powerline Communication, design and construct a BPL modem. The theoretical part of the thesis covers the division and description of Powerline Communication, its standards, and factors affecting communication over electrical wiring. The practical part includes the design of a printed circuit board for the BPL modem with the selection of necessary components for the modem construction. The output of the thesis is a constructed broadband PLC modem, whose transmission properties and interference resistance are compared with commercially available solutions.

Impact of devices connected to powerline on selected BPL topologies
Mahút, Michal ; Musil, Petr
The following article deals with the impact of device originated noise on BPL (Broadband over powerline) communication for different topologies of BPL modems. In household scenario, every device connected to power line has an impact on transmission spectrum and limits throughput. Different topologies and two types of devices were tested and evaluated. The aim of this article is to determine the appropriate connection of BPL modems into the powerline with the lowest possible decrease of data throughput.
