Open Mobile Phone Platform
Malinčík, O.
The market provides a wide variety of GSM mobile phones, however, a platform which offers free hardware access is not known. The open mobile phone platform fills this gap and it allows user to approach it on electronic component level, what is useful for educational purposes. The paper describes the platform on the block diagram level with brief overview of used components.

Indoor positioning systems, implementation and realization
Strnad, Pavel ; Bruckner, Tomáš (advisor) ; Pavlíček, Luboš (referee)
Bachelor thesis deals with the topic of localization inside buildings. The first part deals with the technologies and systems used for localization, while explaining the basic princi-ples and problems of implementation of these systems, their benefits and disadvantages. This section explains the functionality of each technology and the purpose for which it is best suited. The next part deals with the actual implementation of the localization system Redpin within the campus of the University of Economics in Prague. This section summarizes basic information about the project Redpin, then there is dismantled architecture of the system and its functionality. The remaining part is devoted to the direct implementation of this system. There are specified used technologies, decommissioned installation process and eventually re-evaluated results of its testing.

Analysis of mobile operators’ services
Pávek, Jan ; Jandoš, Jaroslav (advisor) ; Ćech, Milan (referee)
The theme of this bachelor thesis is the analysis of mobile operators' services. The first part is to map technologies for operation of mobile networks. Furthermore, these technologies will be assigned to particular Czech mobile operators. For each technology I will introduce the actual coverage. The acquainting the reader with the technological aspect is followed by an analysis of the offered services. I will take into account all Czech mobile operators. It concerns companies Telefónica O2 Czech Republic a.s., T-Mobile Czech Republic a.s., Vodafone Czech Republic a.s. and Mobilkom a.s. I also chose a foreign mobile operator -- T-Mobile Deutschland. At the end I make a practical test of selected technologies for mobile data transfer. The aim of this study is to compare the Czech mobile operators in technological point of view and also in offered services aspect. I will concentrate on supply to end consumers. Services are divided into categories: prepaid cards, voice flat-rates tariffs and mobile broadband tariffs. Within each category are made recommendations for specific customer groups. Analysis of the German mobile operator is to confront the Czech mobile operators with foreign countries. In a practical test, I verified the actual parameters of the recently launched 3G network of mobile operator Vodafone. Overall, the work could help in the orientation of technologies for mobile networks and should facilitate the selection of appropriate mobile services, including the choice of mobile operator. For elaboration of the subject I used technical literature dealing with mobile communications. Presentation of mobile operators was held at the base of their press releases and selected articles on the Internet. Current price lists of mobile operators have been the source of information for analysis of mobile services. Practical test was executed with equipment borrowed by Vodafone Czech Republic.

Internet connection for mobile users
Špírek, Martin ; Pavlíček, Luboš (advisor) ; Gála, Libor (referee)
In this work I am writing about more and more occurring phenomenon, which is opportunities to connect to the internet for mobile users. I am describing and comparing technology to serve those internet users who need to connect from different locations, or require a connection to the internet on their travels. In the first part of thesis I am explaining the most important and frequently occurring terms, which will help to better understanding and orientation in other parts of the work. The chapter "Definition of basic terms" is followed by chapter "Wireless technology connection" in which are described in greater detail the various technologies available for wireless internet connections and also the advantages and disadvantages of this connections. The second part of my work is focused more practical. There are mentioned real possibilities how to connect wireless to the internet available in the Czech Republic and they are compared with each other. There is also a comparison of mobile operators and their services, which are involved in providing internet access. I tried to also explain here what type of connection is suitable for whom. There are also given here the results of the measurements of speed and quality connection provided by mobile operators. The goal of my work is to acquaint readers with in these days very different wireless options how to connect to the internet and their basic characteristics and then comparing these technologies to facilitate the selection of potential users for the best type of connection.

Development and Prospectives of Mobile Connection in The Czech Republic
Bičík, Petr ; Toman, Prokop (advisor) ; Čandík, Marek (referee)
Mobilní telekomunikace se staly nedílnou součástí našeho každodenního života a proto je jejich rozvoji věnována velká pozornost. Tato práce se pokouší podat současný pohled na problematiku mobilních telekomunikací, které slouží k bezdrátovému přenosu dat. Úvodní kapitola se zabývá historickým vývojem mobilního připojení v ČR. Dále jsou popsány jednotlivé technologie, které jsou využívány pro mobilní připojení k internetu. V závěru práce je nastíněn předpokládaný vývoj mobilního připojení na internet a jsou porovnány jednotlivé technologie. Na základě výsledků provedeného průzkumu jsou diskutovány silné a slabé stránky současného mobilního připojení.

Informatizace a globalizace
Michal, Marek ; Rosický, Antonín (advisor) ; Marek, Petr (referee)
Práce znázorňuje význam mobilních technologií pro společnost nyní i přínos těchto technologií do budoucna. Také je zde popsán vliv a provázání mobilních technologií s výpočetní technikou. V práci jsou popsány nedostatky současných technologií a služeb, pravděpodobné nedostatky technologií a služeb právě zaváděných a z nich logicky vyúsťující požadavky na technologie a služby budoucí.

Informační infrastruktura telekomunikační společnosti
Feglar, Tomáš ; Čulíková, Stanislava (advisor) ; Muller, Pavel (referee)
Význam telekomunikačních společností je nesporný. Pozoruhodné je množství finančních prostředků, které přes tyto společnosti proudí. Částky obratu, které dosahují miliardových hodnot, řadí tento sektor mezi finančně nejproduktivnější. Oblast mobilní telekomunikace se dostává za rámec chápání jedince. Množství systémů, kterými každá společnost disponuje je několik set. Orientovat se v problematice je velmi obtížné a udržovat si povědomí o všech novinkách téměř nemožné. Základní stavební kameny velkých mobilních operátorů jsou však stejné a to je problematika, kterou tato práce popisuje.
