VDSL2 vplus and G.fast technologies and their testing
Vehera, Vladyslav ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This semester work focuses on the basic characteristics of the VDSl2 and G.fast technologies that allow to transfer data using old telephone lines. The theoretical part of the work describes the main parameters of all currently known profiles for VDSL and G.fast. There is also a description of DMT modulation, used in both types of DSL connections. Moreover, the theoretical part presents a vectoring technique that helps to increase the data transfer rate using a twisted pair. The work also provides methods for testing networks using the recommendations of RFC 2455, ITU-T Y.1564 and RFC6349. The practical part of this thesis contains all conducted tests and measuring, which were described in detail. The results od these tests were presented in the format of graphs and tables.

DSL analyzer
Hála, David ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This bachelor thesis is devoted to the development of an application for signal analysis using xDSL technology. The first part of the thesis describes the basics of these tech- nologies and the theoretical assumptions that can be expected in later analysis. Also the parameters measured by the resulting application are explained. The second part of the thesis is devoted to the description of the procedure and solution of the practical part of the thesis - program development. Finally, in the last chapter of the thesis, the program was tested in laboratory conditions and graphs were constructed from the results.
