Wireless Network
Bárta, Tomáš ; Knoth, Marek (referee) ; Koch, Miloš (advisor)
This thesis describes the design model of the wireless network at Rašínovo College Ltd. After studying theoretical knowledge concerning the issues in the implementation of wireless networks, which is dealt with in the theoretical part, the practical part is devoted to its practical requirements of the customer, the current state of the infrastructure and the subsequent draft model of wireless networks in the new school premises. When processing the project that is central to this work, it was necessary to take into account many aspects such as the implementation environment, it was necessary to select the appropriate network security with regard to the purpose of the network and the sensitivity of the transmitted data. In the final part, appropriate hardware was selected and economic analysis of the project was developed.

System for Supervision of Access Points
Stodůlka, Daniel ; Jurzykowski, Michal (referee) ; Maršík, Lukáš (advisor)
The goal of this thesis is to design and implement system for supervision of accesspoints and also implement remote control system. The system consists of three sections - control program, web client and server system which gives an overwiev of all connected monitoring devices. The purpose of this system is to prevent connection outage by constant backup battery voltage checking and temperature control. The system will also warn provider by sending an email if these values go over certain limits. Overview of readings is also available in the form of web client which displays all necessary data. The monitoring device can also be controlled via the client. As a monitoring device the SDS MICRO product was chosen.

Minimizing the effect of interference on wireless network
Doležal, Jan ; Kyselák, Martin (referee) ; Škorpil, Vladislav (advisor)
This thesis is concerned the technology with technologies of transfer through wireless devices. It is about possibilities of optimization of transfer in wireless net, especially of the reduction of interference influence. The first part is about theory and the standards development of wireless technology. There are methods and principles used in wireless technologies. The second part is a practical measuring and testing of an internal wireless net, with the emphasis being on the source of interference influence. Measuring was focused on interference between access points and was not about meteorological influence. It continues with theory and testing of interference of the microwave oven in our wireless net. Then, it is a practical demonstration of interference in an external environment. There are practical examples of interference between different providers’ nets on the same area and solutions to prevent or to cancel this interference. In next part of work the wireless net is parsed and described in a given territory. Here is described the way how to precede the reciprocal interference and eventually how this mutual disturbance suppress. Consequently, our net is optimized for customer growth and for today’s options of newer and more powerful components for wireless transfer. Finally there are two laboratory tasks. The first one is about practical measuring and testing of wireless net’s parameters and the second one is about simulation of wireless networks in the Opnet program.

Design and implementation of a system for exchange of statistic information on network traffic between access points of WLAN network
Lenk, Peter ; Růčka, Lukáš (referee) ; Molnár, Karol (advisor)
This thesis explores the possibilities of implementation of methods for data acquisition in wireless access point MikroTik while using virtualized OpenWRT system. First part of the paper contains short introduction into device’s features and extention of the features by virtualizing the operation system. Design and implementation of the scripts for average load of interfaces data acquisition is in the second part of the paper. The next part deals with the transmission of the gathered data and implementation of the proposed programs in C language. The last part of the paper covers the implementation of a complete program to collect, send and receive data with the option of parameters configuration, and automatic acquisition of the configuration.

Primary School Computer Network Design
Badin, Vojtěch ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
This master’s thesis is focused on the design of a functional reliable computer network for primary school. The master ‘s thesis analyses the current state of the communication infrastructure of the primary school and the own solution is implemented based on this analysis. Part of the solution deals with implementation of an application for distance education and the basic setup of the school computer server. The master ‘s thesis contains the design of cable routing routes, selection of active elements, Gantt chart of the project and economic evaluation of the whole project.

Device for automatic measurement of volt-ampere characteristics
Ondráček, Petr ; Vrba, Kamil (referee) ; Lattenberg, Ivo (advisor)
The Master's thesis discusses the design and realization of electronic meter of volt-ampere characteristics using Wifi module ESP32. The device is designed to be able to measure the characteristic in the voltage range of +/- 20 V and current range of +/- 200 mA. The device is controlled by web interface. The user is able to connect to it with for example his or her smartphone. This interface enables the user to configure various parameters, including the range of measurement and the power restriction. Furthermore, it is possible to graphically display the measured characteristic and export the data. To be independent on the outer network, the ESP32 is operated as an access point, which is creating a new simple network without the internet connection. In the Master's thesis, the principle of voltage and current measurement is explained theoretically, the circuit connection of device and the printed circuit board are designed and the cover of the device is modeled. Also the process of creating the device according to the design is described and the cover of the device is printed on 3D printer. After that, the control program is designed, described and uploaded into the resulting device. Finally, the functionality of the device is tested by measuring the volt-ampere characteristics of a few components.
