Implementation of the LTE Cat-M1 Communication Technology Using the Network Simulator 3
Maslák, Roman ; Možný, Radek (referee) ; Mašek, Pavel (advisor)
The Diploma work deals with the implementation of LTE Cat-M technology in the simulation tool Network Simulator 3 (NS-3). The work describe LPWA technologies and their use cases. In first are described the main parts of the Internet of Things (IoT) and Machine-to-Machine (M2M) communication. Subsequently are described and defined the most used technologies in LPWA networks. Technologies which are used in the LPWA networks are Sigfox, LoRaWAN, Narrowband IoT (NB-IoT) and Long Term Evolution for Machines (LTE Cat-M), where LTE Cat-M technology is described in more details. Simulations are simulated in simulation tool NS-3 and use LENA module. In NS 3 tool are simulated Simulations, which give us informations of Network state according to different Network set up. At the end are done changes of Radio Resource Control (RRC) states in NS-3 tool. These changes are required for correct implementation LTE Cat-M technology in NS-3 tool. Then we are able to simulate simulations, which meet to definition of LTE Cat-M technology.

Implementation of Communication Technology LTE Cat-M1 Utilizing the Network Simulator 3
Drápela, Roman ; Jeřábek, Jan (referee) ; Mašek, Pavel (advisor)
Diploma thesis deals with the implementation of LTE Cat-M1 technology in simulator NS--3 (Network Simulator 3). The theoretical part of the thesis summarizes key terms concerning IoT (Internet of Things), M2M (Machine-to-Machine) communication, LTE (Long Term Evolution) and LPWA (Low-Power Wide Area) networks. The practical part summarizes the possibilities of currently available modules for cellular technologies for NS-3, ie. the LENA module and the subsequent extension of LENA+ and ELENA. Simulation scenarios offer a comparison of LTE/LTE-A and LTE Cat-M1 (also known as eMTC - enhanced Machine Type Communication) technologies for M2M communication. The results of the simulations are well-arranged in the form of graphs and discussed at the end of the thesis.

The Feudo-vassal System on Royal Estates in Early Modern Bohemia
Novotná, Markéta ; Žemlička, Josef (advisor) ; Maur, Eduard (referee) ; Mikulec, Jiří (referee)
Markéta Novotná Abstract - The Feudo-vassal System on Royal Estates in Early Modern Bohemia The study is devoted to the topic of feudo-vassal relations in early modern Bohemia presented on a sample of specific royal and chamber domains at the castle Karlštejn. The first part of the thesis describes how the feudo-vassal tenures were treated in Czech and European historical studies, using impulses from the philosophy and sociology. The others chapters are dedicated to the main object of this analysis - to the Karlštejn vassal system - a group of small-sized estates connected to castle Karlštejn through feudo-vassal bonds. The second chapter of the thesis deals with the problem of historical consciousness, where the castle Karlštejn is imagined as the site of "the national memory", which strongly effected the interpretation of the Karlštejn vassal system. The third (main) part of the thesis presents the factual analysis of the Karlštejn vassal system from the last third of sixteenth century to the turn of the seventies and the eighties of the next century. At the end of the study the analysis of four chosen vassal estates is added. Key words: Karlštejn, historiography, vassals, feudal system, domain, chamber, lower nobility
