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.

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.

Designing of a Fiber Optic Network for Connecting Blocks of Flats in Kojetín
Rumplík, Martin ; Vojáček, Dušan (referee) ; Ondrák, Viktor (advisor)
The subject of this diploma's thesis is to create a design of a fiber optic network, which will allow an access to broadband internet connection for households living in blocks of flats in Kojetín. For this purpose the best technologies will be compared by analysis and the new network topology will be designed. The investor is a civic association Cyrilek.net that provides a wireless internet at this area. The best solution will be selected on the basis of financial and technical analysis and the investment will be calculated including its return. This innovation not only give people a really fast internet connection, but also the possibility of other services such as IPTV or VoIP.
