Remote control of Solar inverter
Pohorský, Ondřej ; Kopečný, Lukáš (referee) ; Burian, František (advisor)
This thesis deals with the design and implementation of a remote monitoring device for the solar inverter SOFAR HYD-10-KTL-3PH. The assignment of this thesis was based on the knowledge and requirements of the author. The aim of this thesis is to create a device communicating with the inverter. The device will display the essential parameters on the website. From the website it should also be possible to control the outputs of the device, which can be used to switch appliances.

Tools for Wi-Fi and IPv4 penetration testing
Jančík, David ; Lieskovan, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
The master thesis deals with the design and implementation of support tools and methodologies for security penetration testing of Wi-Fi networks and IPv4 network infrastructure. The theoretical part covers penetration testing itself, approaches, phases, and types. It also describes the development of Wi-Fi networks and their security protocols. Various penetration tools for Wi-Fi networks and types of attacks are introduced. In the last theoretical part, a basic overview of IPv4 and tools for IPv4 scanning is provided. Initially, in the practical part, a proprietary methodology for Wi-Fi networks and IPv4 and tools for penetration testing are proposed. The Python programming language is defined, along with the output of various tools for the Penterep platform. A review of tools from the theoretical part is conducted to select suitable tools for new support tools. The implementation of penetration tools is based on the design diagram created. The conclusion summarizes the results achieved and suggestions for further expansion of tools for Wi-Fi and IPv4. The result of this thesis is the implementation of support tools and the design diagram for Wi-Fi networks and IPv4.

Coexistence of LoRa and Wi-Fi in the RF band 2.4 GHz
Kaučiarik, Filip ; Miloš, Jiří (referee) ; Polák, Ladislav (advisor)
Diplomová práca sa zaoberá štúdiom koexistencie, ktorá môže nastať medzi bezdrôtovými komunikačnými systémami LoRa a Wi-Fi v bezlicenčnom ISM pásme 2,4 GHz. V teoretickej časti práce sú stručne popísané fyzické vrstvy obidvoch systémov. Následne sú definované spoločné frekvenčné pásma a koexistenčné scenáre, ktoré môžu vzniknúť medzi uvažovanými systémami v spoločnom rádiofrekvenčnom (RF) pásme. V experimentálnej časti práce je prezentované laboratórne meracie pracovisko, ktoré bolo navrhnuté na meranie rôznych koexistenčných scenárov medzi technológiou LoRa a Wi-Fi. Funkčnosť navrhnutej koncepcie je overená experimentálnym meraním. Výsledky meraní sú detailne komentované a prezentované. Je navrhnutá laboratórna úloha a vzorový protokol pre vzdelávacie účely v Laboratóriu Mobilných a Bezdrôtových komunikácií.

Development of electronic parking system
Šmíd, Josef ; Strecker, Zbyněk (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the development of the electronic parking system, which is intended to navigate the drivers to the nearest vacancies, using the Arduino platform. The introductory part deals with an overview of the current state of knowledge. The research section provides an overview of the Arduino base plates and other modules and sensors selected for conceptual design solutions. The construction part deals with the design of the casing according to the selected components and the subsequent realization of the whole device, including the program, for testing under real conditions. The test results are finally evaluated and summarized in the final discussion.

Free-Space Optics data link
Šála, Jakub ; Číž, Radim (referee) ; Šporik, Jan (advisor)
In this thesis, shows a current issue for free space optics, limiting their use in practice with regard to the availability and reliability. They conducted measurements on wireless optical links and the observed values is calculated by the availability of the connection. Subsequently, measurements are performed on alternate versions of wireless and copper connections. Observed values were compared with a wireless optical link. It is made of optical design of wireless connections at home.

The project for building a member database
Rumplík, Martin ; Krč, Petr (referee) ; Kříž, Jiří (advisor)
The object of this bachelor's thesis is to create a design of database for needs of a civil association Cyrilek.net. The objective of this database is to cover all registration processes in frame of this organization, which deal especially with filling personal information and notes about installed hardware. An user interface for access to the database will be also designed and partially realized in form of information system, which will be accessible through web browser.

SIW slot antenna
Martinec, Matěj ; Puskely, Jan (referee) ; Pítra, Kamil (advisor)
This work is dealing with the design of waveguide slot array antenna and SIW slot antenna with coaxial and microstrip feed operating in 5,6 GHz frequency in Wi-Fi frequency band of IEEE 802.11ac standard. For design of these antennas were used calsic methods and each of this parts were optimised in CST Microwave Studio. In this programme were optimised parameters of each part to occupy widest bandwidth of antenna, which was in conflict with the proper function of antenna. All antennas were compare between each other in light of selected parameters and suitable antenna has been chosen.

Drone swarm control
Kolísek, Josef ; Marcoň, Petr (referee) ; Janoušek, Jiří (advisor)
This thesis focuses on the drone swarm control and the using in practice. It is about the interconnection of several control units of drones and subsequent coordination in the air. The work is divided into theoretical part and practical part. The practical part describes the possibilities of drone swarm flying and coordination of multiple drones. Possible ways of communication and transmission of telemetry data for control using the MAVLink protocol. The next part describes the possibilities of controlling multiple units from one central point and creating flight instructions. The practical part deals with the realization of the software for synchronized flight of two unmanned aircraft and their connection with the ground control station for the transmission of flight instructions. The last part of the work deals with evaluation of the control, compliance of the established flight plan and the proposal of other possibilities for improvement with the solution of deficiencies.
