Advanced Roaming in Wi-Fi Networks
Krulich, Filip ; Krajsa, Ondřej (referee) ; Ilgner, Petr (advisor)
This work deals with the issues of Wi-Fi roaming. It describes, how amendments of IEEE 802.11 focused on roaming, namely 802.11r, 802.11k and 802.11v, deal with these issues. Part of this work is designing a topolgy based on OpenWrt system, on which to test roaming before and after using these amendments. After testing, lower roaming times are exhibited, thanks to using these standards. There is also designed an identical topolgy based on Mikrotik devices, on which it’s demonstrated, that Mikrotik devices do not support these standards.

The diploma thesis is focused on exploring the possibility of VoIP service in a wireless network of University of Economics, Prague. This thesis describes the basic principles of VoIP and related wireless technologies necessary for its quality and stable operation. Subsequently, different configurations of wireless network and end clients are tested and compared, including its impact on ordinary users, in a laboratory environment with idle and fully utilized frequency band. Finally, a roaming operation with the use of several advanced 802.11 standards is tested in the real environment of the Old building in Žižkov. In conclusion, the ideal settings for all telecommunication devices are recommended in order to maximize the quality of VoIP operation and to minimize the negative impact on ordinary users.

Burian, Martin ; Bič, Josef (advisor) ; Šaroch, Stanislav (referee)
The aim of this thesis is to analyze the impacts of European Union's roaming regulation on company T-Mobile Czech Republic, a.s. For customers, reducing of roaming prices is a welcome step, on the other hand, telecommunication companies have a different opinion and the impacts on companies are doubtful. In the theoretical part I will try to describe the roaming service and introduce the content of roaming legislative regulation, which the company must follow when creating roaming strategy. The practical part will include the real impacts of European Union's roaming regulation on company T-Mobile Czech Republic, a.s., such as usage of roaming services, new roaming tariffs or company's financial indicators. At the conclusion I will try to predicate possible future roaming development because lately talking about the abolition of roaming fees, which could mean the completion of the single European market in telecommunications.

Is the only result of mobile operators´ union price regulation cheaper roaming rates?
Kohoutová, Iveta ; Janíčko, Martin (advisor) ; Thorovský, Jan (referee)
The aim of my work is to evaluate the effect of roaming price regulation on the market of mobile phone operators and determine, whether the only result of union price regulation of mobile operators is cheaper roaming rate. The roaming price regulation mainly resulted in the decrease in the cost of messages, calls (both incoming and outgoing) and data services when using the phone within the European Union. Roaming prices were previously very high. The roaming prices have dropped significantly since 2007, when the EU roaming legislative was introduced. I came to conclusion, according to established data, that mobile operators' roaming price regulation have affected also other spheres (mainly cost of messages sent to foreign phone numbers). Furthermore roaming price regulation have affected delay of domestic prices - cutting and developement of services.

The Roaming Regulation
Koblihová, Veronika ; Císař, Jan (advisor) ; Gráf, Václav (referee)
This diploma thesis examines the issue of the roaming regulation. The goal was to find out whether it had been necessary to regulate roaming prices at the EU level and what consequences it has and will have for individuals in the market - especially consumers, mobile operators, politicians, and also for the single European market. The basic hypothesis is that the roaming regulation will ultimately lead to a reduction in consumer utility, and therefore there is no substantial improvement to the single European market. The first part describes current developments in the roaming regulation and presents arguments for and against regulation. The second part then discusses the presented arguments. The impact on various market players is examined using the available data.
