Measurement of qualitative parameters in the access network
Kejík, Tomáš ; Slavíček, Karel (referee) ; Grenar, David (advisor)
The theme of this bachelor’s thesis is „Measuring of qualitative parameters in an access network.“ The aim of this paper is a characterization of multimedia broadcasts in access networks and the creation of a functional network generator. The theoretical part of the paper is dedicated to analyzing key broadcasting parameters, which affect the resulting quality of network broadcast. Furthermore, used network protocols that are given for network and multimedia broadcast are analyzed. Simulation is done by using of GNS3 software. After that, transferred data were measured. Side effects affecting the functionality of the resulting transmission were subsequently analyzed. Another part of the paper is the practical part, which is focused on creation of a network generator by using the Bash language and making a script to facilitate turning on the generator for different counts of clients. At the end of the paper, the broadcast parameters were evaluated.

Data logger for serial communication lines
Jankech, Tomáš ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
The aim of bachelor’s thesis is the realization of data logger for serial communication lines. This paper describes basic concepts of serial communication and looks more deeply into RS232 and RS485 serial communications standards. It describes usual methods of data recording and their application in practice. Data logger’s block diagram is described in detail for each of its parts. Their descriptions contain an overview of circuits, which allows realization of individual blocks and circuit diagram of selected circuit. Following chapters describes design of printed circuit board, control application for PC and firmware for the microcontroller.
