The realization of the data communication for application to the mobile networks
Sodomka, Lukáš ; Růčka, Lukáš (referee) ; Jelínek, Mojmír (advisor)
Thesis deals with data technology, which can be used for communication between mobile and IP networks. The aim of the project is to design data communication and the subsequent implementation of the mobile and IP networks. First of all, it made an introduction to telecommunications systems with focus on GSM. Subsequently, the work examines data provided by GSM technology standard with a focus on GPRS, which is in the other chapters discusses in more detail. The resulting communication application protocol is designed in two versions, which is achieved by the creation of an autonomous system. Communication is implemented using JAVA programming language, which created an application client, server and implemented application protocol. Client application is tested on a mobile phone with Internet connection with support for GPRS technology. Server application is installed on a PC workstation, which is assigned a public IP address, it is easily addressable from the Internet.

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.

Mobile Communications in the Czech Republic
Diblík, Jaroslav ; Přibil, Jiří (advisor) ; Zelená, Veronika (referee)
The thesis deals with the topic of mobile communication in Czech republic. Its main task is to make reader fimiliar with different types of technology and digital standards on Czech mobile communication market. Thesis shows mobile communication providers in Czech republic, not only the conventional ones, but especially virtual operators(MVNO). It defines the legislation and position of Czech Telecommunication Office (ČTÚ). At the end, it analyzes the current market situation and try to offer the best solution for possible customer and also tries to find out whether it would pay off to the customer to switch to the virtual operator, based on mobile tariff price calculator.
