Verification of Properties of WiFi IEEE 802.11n
Alexa, Jan ; Miloš, Jiří (referee) ; Kuder, Zenon (advisor)
This bachelor thesis is focused on introducing with WiFi standard – IEEE 802.11 in general. A deeper focus is devoted to modern standards 'n' and 'c', showing the main differences and innovation compared to older standards 'b', 'g', 'a'. Furthermore, this work focuses on the use of MIMO technology. The last part is devoted to the design of laboratory tasks for teaching at the undergraduate level, which demonstrates the use of MIMO technology. Part of this thesis is an application that demonstrates the differences between those standards.

Verification of Properties of WiFi IEEE 802.11n
Alexa, Jan ; Miloš, Jiří (referee) ; Kuder, Zenon (advisor)
This bachelor thesis deals with wireless systems of IEEE 802.11 standards. This thesis explains the fundamental terms and principles, which are relating to digital wireless systems. This thesis is structured into four thematic units. The first chapter discusses an introducing with Wi-Fi standard – IEEE 802.11 in general. Second part contains a deeper focus on modern standards 'n' and 'ac', showing the main differences and innovation compared to older standards 'b', 'g', 'a'. Further in this part of the thesis is described using of MIMO technology. The third chapter contains an analysis and description of the application, which is part of the thesis. The fourth part is detailed focused on to the design of laboratory tasks for teaching at the undergraduate level, which demonstrates the use of MIMO technology.

Analysis of human tremor by using hight speed camera
Kuder, Zenon ; Čmiel, Vratislav (referee) ; Rychtárik, Milan (advisor)
This thesis investigates the possibility of using the Olympus iSpeed 3 high-speed camera and light-emitting diodes in visible light spectrum to analyse human tremor of upper limbs. Moreover, it discusses possible realization of a measurement apparatus including software implemented in the Matlab environment. The system is then tested on a small sample of healthy subjects.

Modelling of Network Coding in Wireless Networks
Svobodník, Petr ; Miloš, Jiří (referee) ; Kuder, Zenon (advisor)
During data exchange in the Point-to-Point wireless topology, in case where end nodes aren’t accessible directly, a relay is deployed. However, the basic approach to relays – Store-and-Forward – isn’t the way to reach the maximum throughput. Network Coding operation is performed by combining data words (packets) travelling through the network in opposite directions into one packet. End nodes, with knowledge of the data sent, can decode received packet. Packet exchange is then finished in shorter time which results in an increase of network throughput. There are more methods of Network Coding which differ from each other in the time requirements or the ability to work in a noisy channel. In this paper they will be described and compared.

Routing Protocols for Lossy Wireless Networks
Kuder, Zenon ; Prokopec, Jan (referee) ; Šebesta, Jiří (advisor)
Tato práce zkoumá vhodnost a požadavky návrhu simulací pro simulátor NS-3 pro případ bezdrátových sítí používaných v měřící infrastruktuře společnosti Kamstrup. V práci je popsán simulátor NS-3 a je vytvořena základní implementace dvou protokolů. Wireless M-Bus jako příklad jednosměrného protokolu pro zařízení napájené z baterií. Simulace Wireless M-Bus je porovnána s daty naměřenými v reálném systému. NS-3 poskytuje flexibilní prostředí pro vývoj simulací různých síťových protokolů, včetně těch určených pro sítě inteligentních měřidel.
