Project for utilizing Mobile Technology
Makovský, Marek ; Smílek, Pavel (referee) ; Kříž, Jiří (advisor)
In my present work first I introduce the readers to the development of the standard of the prezent wireless mobile network and consequent possible development together with introducing certain recommendations. In the first, theoretical part, are described commercial wirelees systems used by most mobile operators in Europe. The following part deals with the analyses of the present situation and summarizes existing ceses of using mobile technologies. The last part deals with concrete projects recommanding utilizing mobile networks and summarising the problemes of data communication between the controlling part and transmitting terminal on the other end. In the conclusion you will find the recommandation.

Convergent Mobile Technology Solutions for Corporate Customers
Stančík, Michal ; Tomek, Martin (referee) ; Kříž, Jiří (advisor)
Bachelor’s thesis deals with ways how to use convergent solutions of mobile technologies as benefit for corporate customers, especially small real estate agency. Theoretical area describes basic voice and data transfer’s principles and technologies in mobile networks. Second part analyse key working processes and tries to reveal deficiencies in current real estate agency’s telecommunication system. Practical proposal shows how to remove discovered deficiencies by adjustment of key working processes and afterwards apply the most useful functionalities of convergent solution. In the end there is a costs comparison between current and suggested telecommunication system.

Performance Analysis of Mobile Networks for M2M Communication
Důbrava, Marek ; Kováč, Dominik (referee) ; Mašek, Pavel (advisor)
This bachelor thesis "The benchmark analysis of mobile network for M2M communication" focuses on theoretical study of M2M devices and third- and fourth-generation mobile networks. The second part of the thesis is devoted to the LTE network overload simulation. The LTE network overload is achieved in two ways: the overload caused by the volume of data transmitted, or the overload caused by devices newly connected to the network. The third part of the thesis deals with the design and simulation improvement of M2M communication in the LTE network. A network simulator OPNET Modeler was used for the simulation.

HW platform for surveillance over maritime container transport
Roško, Tomáš ; Možný, Radek (referee) ; Musil, Petr (advisor)
The complexity of international transportation is increasing, and with that, the logistics requirements also increase: such as the need to monitor containers’ location or measure inside conditions. Despite these demands, marine transportation faces specific technical problems, such as the need for sending data precisely, often, and with low energy consumption. This paper aims to create a monitoring device that meets the demands of marine transportation. The device combines satellite and mobile networks to control the container location and, at the same time, allows for precise pinpointing of place and availability of access while having low battery consumption. The theoretical part of the paper explains the process of selecting components and justification of the process with regard to market options. The practical part contains a diagram of the connection of the modules and sensors. Next, the design and manufacture of the printed circuit board and custom 3D printed box are discussed. The software part deals with data protocol and the description of the application, which is then tested with a particular focus on measuring and transmitting the values onto the server.

Surveillance system for Internet Protocol Multimedia Subsystem
Švec, Michal ; Doležel, Radek (referee) ; Nagy, Ľuboš (advisor)
The master’s thesis describes IMS (IP Multimedia Subsystem) in terms of IMS core ele- ments (functional description, different implementation, signaling etc.) Communication protocols SIP and DIAMETER, together with SNMP protocol, which is used for collecting data are briefly described in this thesis.Thesis is also describing various IMS projects to- gether with Open IMS project, for whom was this surveillance system designed. Next part deals with architecture design of surveillance system along with management options implemented in surveillance system for users and administrators. The main part of master’s thesis deals with the description of the surveillance system for the experimental school Open IMS network and describes the remote configuration of core elements and monitoring of network traffic, together with the monitoring servers performance. The most of the data in the designed surveillance system are processed into graphs, which are regularly updated. The final part of master’s thesis describes the configuration and implementation of monitoring tools MRTG and NfSen that were used in created web based surveillance system.
