Influence of physical parameters and age of power lines on PCL/BPL performance and reliability
Janás, Jan ; Mlýnek, Petr (referee) ; Benešl, Lukáš (advisor)
With the increasing demands on data transmission, other ways are being sought than standard data transmission via conventional data cables. One of these ways is communication over power lines - PLC or BPL technology. This method of communication is widely used in households, energy, industry and other fields where it is used for data collection, communication, or control of various devices. Before considering the use of BPL technology, it is first necessary to evaluate the considered power line to see if it is suitable and technically competent for this purpose.

Influence of physical parameters and age of power lines on PLC/BPL performance and reliability
Benešl, Lukáš ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
BPL technology is quite widespread nowadays and the public is also somewhat aware of it. This technology can be used as a means of communication without the need to install additional media and thus use the existing infrastructure. In an effort to use the full potential of the technology, BPL communication began to be used to monitor the current state of cables in distribution networks online. Where the technology is already fully implemented, the distributor can use the data to evaluate the current situation. In this way, BPL technology can be used as a diagnostic tool to test the quality of a cable connection on which not only time but also humidity and other external influences could have a significant effect.

Intelligent system for remote data collection with PLC
Benešl, Lukáš ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
Bachelor thesis deals with PowerLine Communication (PLC), analyzes its advantages and disadvantages of this technology. Shows the frequency division according to the frequency range in which they work. The work includes a methodology of PLC communications testing according to Request For Comments (RFC) 1242 and RFC 2544 standards. Tests of the individual modems were measured in the household on a real network. All modems measured the same topology, and the results were appropriately processed in the form of well-arranged tables and charts. In conclusion, the individual conclusions from the measurements are always discussed. For the measurement of narrowband PLCs with multiple carriers on PRIME and G3 standards, the SAM4CP16C-EK development kit from Atmel was used. Narrowband modems, with single carrier, are represented by the PLC MT49R model manufactured by ModemTec. For broadband modems, the HomePlug AV2 standard was selected in comparison with HomePlug AV. Within the HomePlug AV2, the I2SE PLC Stamp 1200 micro EVK and Linksys PLEK500 development kit were used. For the lower standard of HomePlug AV, PLC was used by COMFAST.
