Quality and accessability measurement of GSM network
Vondra, Marek ; Wieser,, Vladimír (referee) ; Hanus, Stanislav (advisor)
The thesis is specialized on a possibility of measuring qualities and availability of a cellular radio system and also on evaluation qualities, fruitfulness interface, permeability etc. It includes short description of a basic mobile technology. Further analysis of the possibility of measuring the mobile network and how implement the measure. It also includes a draft program for measuring and evaluation of the GSM network with help several tests by a mobile phone connected through the Bluetooth.

Femto cells in next generation mobile networks
Bernkopf, Jan ; Štencel, Vít (referee) ; Hanus, Stanislav (advisor)
This paper provides theoretical analysis of LTE network and Femto cells. Its presents their modulation and transition techniques, their performance and of course implementation of Femto cells into LTE macro-layer. It also describes potential risk of interference between LTE macro-layer and Femto cells and provides the way how to solve and simulate interference. Finally it states simulation and analysis of model situations.

Mobile internet principles
Jehličková, Lenka ; Fencl, Josef (referee) ; Hanus, Stanislav (advisor)
Thesis concerns with mobile communications theory with focus on data transfer. In the introduction the history, the origin and individual mobile systems generations are described. It is followed by detailed description of second, third and fourth generation mobile systems. Frequency band allocation, signal processing, the system architecture itself, security management and basic features are also discussed. The GSM system is described together with individual data transmission types based on circuit switching – CSD and HSCSD and packet switching – GPRS and EDGE. For UMTS, FDD and TDD modes are listed as well as changes in individual releases, corresponding technologies and provided services. Next, there is the description of LTE and WiMAX systems, together with their improvements whose are part of the fourth generation of mobile systems. Last of the described systems is the still work in progress HAPS, also known as the system of stratospheric platforms. In the end important parameters are summarized and systems are compared with each other.

High bit rate LTE mobile system
Ohera, Vlastimil ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
Aim of thesis was to acquaint with architecture and process of signal in systems using broadband LTE wireless technology. Thesis in detail is described physical layer of system. Next there is described comparison of LTE and WiMAX and table with all present systems. Thesis also is contained information about tested LTE system in real traffic. Next aim was created simulation of LTE system in downlink and uplink. Interface was created for easier configuration of each characteristics of transfer and type of interference of useful signal. This interface is contained control of whole simulation and presentation of measured values. Measured data were processed into graphs, which show dependence of error rate BER on C/N of useful and interference signal.

Spectrum auction and It's impact on telecommunication industry
Tománek, Petr ; Hořejší, Bronislava (advisor) ; Sirůček, Pavel (referee)
This work adresses oligopoly in telecomunication industry. Proper attention is given to the one of the biggest obstacles in entering the marker, which is acquiring the licence for the radio transmitting. Czech telecommunication Office decided to release these licences in a form of the auction. The work looks on the whole proces from the perspective of the game theory. Each participant is described and considered to be one of the players and regulatory agency as the rule maker of the game. Characteristics of the offered frequencies are alse discussed. The work investigates both of the carried out actions. Their results are examined and compared to the theoretical projections given by the game theory. Finally, a comparison with the auctions from the other european contries is given from the perspective of the outcome and defined rules.

Analysis of current mobile operator selected services
Havlíčková, Klára ; Toman, Prokop (advisor) ; Hirsch, Jan (referee)
The theme of the thesis is an analysis of current mobile operator selected services. This work focuses on the present and the future development of mobile internet connection. The aim is to analyze existing services at Telefónica Czech Republic and The work is divided into several parts. The first part focuses on the selection of a particular operator. I described at al. Czech Republic and Telefónica, which is the first integrated operator in the Czech Republic. The company currently operates more than seven million mobile numbers and fixed lines, making it one of the leading providers of fully converged services in Europe. I focused on the organizational structure of the company and its description. The second part is historical, describes the history of mobile networks in the CR, the history of mobile communications in the data and the development of mobile connections in the country. The third part is theoretical, describes al. Czech Republic Telefonica SpA in terms of services it offers in this section is also described ISO certification, EMS policy and business principles. Are described voice and mobile services, mobile data services and connectivity technologies and different types of technologies (GSM, GPRS, EDGE, UMTS, HSDPA, HSPA + and LTE). Another section includes the development of mobile connections in the CR, the current situation where Telefónica provides 3G connection for almost 71% of the population and the current state of commercial LTE network. I tried to describe the current mobile platforms, and even telecommunications market in the Czech Republic. The penultimate section specifies the geographic traffic distribution network operator and the last part, I dealt with the analysis and comparison services. The total contribution of the thesis see the approach and evaluation of existing services together. Telefónica Czech Republic, as, which is one of the largest telecommunications companies in the world.

Mobile internet in the Czech republic and abroad
Výborný, Vojtěch ; Žamberský, Martin (advisor) ; Bruckner, Tomáš (referee)
This bachelor deals with the mobile Internet in the Czech republic and world-wide. In the first part the development of the mobile Internet in the Czech republic from the beginning up till the current situation is addressed. The following part focuses on the analysis of the Czech providers' market and on respective technologies employed. In connection with this part the biggest providers of the mobile Internet in the USA are being analyzed. The next part outlines the anticipated development of mobile technologies. This forecast is based on analyses and own assumption. The final part consists of the analysis of markets, where T-Mobile is active.

Development and Future Prospects of Mobile Internet Connection in the Czech Republic
Bičík, Petr ; Toman, Prokop (advisor) ; Dudová, Lenka (referee)
Mobile telecommunications belong to one of the fields which still evolves and it is expected that in the future they are going to offer great benefit to the whole world. This work focuses on current and future development of mobile Internet connection in the Czech Republic. At first the technologies used to provide mobile Internet connection are described and compared and then the situation (in terms of technologies and mobile operators) in the Czech market is outlined and its possible evolution in the near future is presented. Furthermore, the tarifs of mobile operators are compared with those in place two years ago. The strengths and weaknesses of the current mobile Internet connection are evaluated based on the conducted questionnaire survey. The latest results are then analyzed and compared with the results from a previous survey conducted in 2007 as part of a bachelor's thesis, which has been further extended in this mater's thesis.
