ISP Network Optimalization
Čech, Ondřej ; Podermański, Tomáš (referee) ; Grégr, Matěj (advisor)
Bachoelor's thesis is focusing on analysis of network local ISP, detecting actual problems and offering a solution for founded problems. There were problems with broadcast-storm, private address space, RSTP protocol settings and DHCP spoofing. The following changes were introduced: OSPF routing, RSTP override, automatic backup, client separation using DHCP. There has been a reduction in broadcast traffic and associated broadcast-storm.

Lighting control system using a wireless communication network
Levek, Vladimír ; Kadlec, Jaroslav (referee) ; Kuchta, Radek (advisor)
The aim of this thesis is to create and describe the wireless system for lighting control. A part of the work is the creation of modules for switching lighting and the creation of their operating programs. The first chapter briefly describes the way how the lighting control works and contains general requirements for the intelligent home. Further, there is a description of IQRF system, which serves as a wireless platform for the system. Next part of the thesis describes individual modules in terms of hardware and software. One part of the work covers the description of the transmission protocol. The attachment includes a listing of all operating programs for this wireless control system.

Company Computer Network Design
Ambroz, Vojtěch ; Jakub,, GERICH (referee) ; Ondrák, Viktor (advisor)
This bachelor's thesis proposes a computer network for a branch of a newly emerging local company dealing with information security. The first part of the work analyzes the current state of the computer network, building, hardware and software requirements and, last but not least, the requirements of the investor. The next part of the work contains general basic information about computer networks needed for designing the concept. This is then elaborated in the third part of the work. It contains specific cabling solutions, all selected devices, but also an economic evaluation of the entire concept.

Upgrade of the laboratory task of KNX system installation
Hrubeš, Zbyněk ; Müller, Richard (referee) ; Bátora, Branislav (advisor)
This bachelor´s thesis deals with both the theoretical analysis of the KNX bus system, but it is also practically focused on working with KNX products and their programming. In the introductory theoretical part are described the KNX bus system itself, its characteristic properties, functional principle, topological arrangement, possibilities of using communication media and the advantages that brings, in comparison with classic installations in houses and buildings. The next section deals with the description of ETS software for design, planning, programming, and commissioning of KNX installations. Furthermore, the assessment of the possibilities of visualizations for the control of the KNX system, the use of visualization tools designed for this and their subsequent implementation in the laboratory task are discussed. The practical part of the bachelor's thesis is focused on the design of laboratory tasks and their programming using EST6 software using jigs with KNX devices from the company HDL Automation, which were made during the semester work. The output of the bachelor's thesis will be laboratory instructions for teaching and a understanding of working with the KNX system.

Variable Two-Way Loudspeaker Cabinet - Laboratory Tool
Rehák, Jan ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
The objective of this work is to build a two-way loudspeaker system that will enable changing loudspeaker topology in both vertical and horizontal axes and to suggest two laboratory tasks. The theoretical part of this work will briefly discuss loudspeaker crossovers. Then it will discuss how topology of loudspeakers in a loudspeaker system can affect its behavior at crossover frequency. Frequency characteristics of various loudspeaker baffles will be shown. On these, the effect of a baffle’s exterior on its behavior will be discussed. A two-way loudspeaker system will be designed. The construction process and drawings of each part are also included in this work. The finished product will be tested and, following from these tests, a conclusion will be drawn about the validity of the theoretical assumptions of its design. After that, appropriate parameters of a crossover for the two-way loudspeaker system will be chosen.
