Mechanisms of QoS assurance in fixed, wireless and mobile data networks
Václavek, Radovan ; Novotný, Vít (referee) ; Molnár, Karol (advisor)
This bachelor´s thesis deals with mapping technologies and base parameters used to guarantee the quality of systems in the local area networks, including wireless and mobile ones. I have focused mainly on requests and classifications, which are typical for the types of networks on link layer. In Ethernet I focused on the gradual trends in the fore mentioned technologies and IEEE 802.1Q and connected IEEE 802.1p standards included. The next part describes the quality of systems in wireless nets in different types of environments and again uses given standards for quality of systems guarantee in 802.11e and connected 802.11a/b/g standards. The next part focuses on the latest generations of mobile nets, looking at the types and trends of the latest technologies. Here I draw from standard project 3GPP, which describes the problems with these technological developments. The next part focuses on WiMAX technologies. In the penultimate paragraph, the constituent network technologies are compared from the view of securing QoS and I propound possible ways of securing coversion of constituent technologies. The conclusion summarises all the technologies I have mentioned and the future trends including possible problems and challenges with these latest technologies.

Construction of Structured Cabling in the Mixed-use Building
Černý, Jan ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
Content of this thesis is construction of structured cabling in the polyfunctional house, that will be built in Frýdek - Místek. This work will be divided into three parts. Into the part about analysis of the current state, theoretical part and practical part. The first part will address the analysis of current state of the structured cabling in the polyfunctional house and the house itself. The theoretical part will cover theoretical possibilities for construction of the structured cabling. The practical part will focus on the proposal of structured cabling, that will comply with all regulations and will meet customer´s requirements.

Optimization of transport network configuration
Švec, Adam ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The communication networks, that we know nowadays has been changing since the time when Alexander Graham Bell discovered the great invention of that time – the telephone. It was mainly the level of the technique and electronics that helped to improve the first systems of connection between each other. This process caused the first communication networks. All the changes were done on the field of the radio operation. The networks were analog and were contained mainly by metallic – cooper wire. On the field of radio communication were mainly electromagnetic waves which maintained the connection of the places where was not able to stretch trunk cables. Communication has made huge qualitative improvement. This process has used different types of wire that were able to transmit higher and higher frequencies and to raise a number of made connections. All those changes were involved in radio network. In 1950s the entertainment was made mainly through television broadcast. This improvement needed the new studios and broadcast systems and also the radio improved. In that time there was huge automatic PBX equipped with stepper drivers matrix switches. The networks started to be divided into access drivers which resulted from the subscriber terminal to the first connection point, for example, the first public telephone exchange. Among these exchanges was formed their interlinking transport or transportation network, to finally, after reaching the target (last panel) would be merged back into the network access for remote users. The aim is to describe some properties of transport networks, the contemporary, which has been fully digital technology. We will focus on data networks, i.e. those that are available to contemporary man, and describe some of the technologies and components that can be used. We meet with OPNET Modeler software and the philosophy of working with him. We recommend optimalization of the designed transportation network on the basis of OPNET Modeler simulation results. Afterwards we design a suitable laboratory task for bachelor degree students of Teleinformatics.
