Modulation signal source for microwave beacon
Belloň, Michal ; Vondra, Vlastimil (referee) ; Kasal, Miroslav (advisor)
This project is focused on construction of source of modulation signal for microwave beacon. The output signal is the same as signal, which is generated by PC software WSJT (Weak Signal by Joe Taylor) on PC sound card output. Signal on device output is modulated using by WSJT modulation and its specific JT4 mode. The device output has I and Q components of signal.

Network virtualization - software defined networks
Veselý, Marek ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The aim of work is a new trend in network architecture, called Software defined networks. Describes function of controller as the main device, which controlling the whole network. Further the communication between switch and controller is here, which controlling protocol OpenFlow. First chapter gently deal with principe of the VLAN networking. Further it is much more oriented with software defined networks, where the main principe is described. Protocol OpenFlow is described in deatail, as his functions are discussed too. There are also advantages and disadvantages and possibility to use this network in university campus.

Design of Avalanche Search
Ondráček, Michal ; Křenek, Ladislav (referee) ; Zvonek, Miroslav (advisor)
The Bachelors project is design of avalanche transceiver. Market situation study, the evolution of technology useful for this product. The design of a transceiver deals with the ergonomic aspects of using beacon in stressful situations and it finds a new ways in constructing of avalanche transceiver.

Mobile application using Google beacon technology
Krajanec, Štefan ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This Bachelor thesis focuses on utilizing beacon technology in Android applications. Beacon technology allows for determining an approximate distance of the user from the beacon.. In order to verify the reference numbers given by the manufacturer we conducted an observation to measure the power of the received signal in reference to distance. 3 brands of beacons were tested, Kontakt.io, PROXioT and IBKS. The observasion has been iterated in an open field setting. Findings from this observation was implemented into an application designed for shopping mall marketing. The application, after getting closer to the beacon distinguishes between different behaviour types; behaviour as an instant notification, as a position log into a database, as a time stamp log (time spent near the beacon) into a database and as a conditional response. The aim was to resolve the problematics of communication with the beacon as universally as possible so the impletation into other projects would be as simple as possible. The aforementioned app is the output of this thesis.
