Support of service quality demands in radio access networks of high speed variants of mobile networks
Kuruc, Jiří ; Skořepa, Michal (referee) ; Novotný, Vít (advisor)
The work deals with the developmental stages (Releases) of the third generation UMTS net-works. It explains a partial improvement from Release 99 to Release 5 and Release 6 to im-prove the quality parameters of a mobile data transmission. In the practical part, there are measured qualitative parameters of the third generation networks that are available in the Czech Republic: UMTS, HSDPA, CDMA 1xEV-DO Rev.0 and Rev.A and UMTS-TDD. The measurements give reasonably achievable data rates in both directions (downlink & uplunk), a response time, quality of VoIP calls, a dispersion, a data-loss and an ability to transmit video with different data flows. The other aspects especially an availability of coverage and end-user terminals have been assessed wihin the each network. The work is supplemeted with a laboratory, which is focused on a practical comparison of the basic parameters of data transmissions of 2G and 3G networks.

Memory Testing on SGI/MIPS Architecture
Rydlo, Karol ; Jaroš, Jiří (referee) ; Kašpárek, Tomáš (advisor)
Work is engaged in making solution for creating own memory tests on graphical station SGI O2. This thesis produces work on MIPS processor architecture and it try to find the ideal environments for testing memory and with it is nearly related looking for chances of start and compile application for SGI O2. Part of my thesis is also target using cross-compilers, for effective and useful work with program for other architecture.

Digital Marketing Strategies - Combination of Digital Media Channels
Turazová, Barbora ; Klimeš, David (advisor) ; Huněk, Filip (referee)
The diploma thesis "Digital Marketing Strategies - Combination of Digital Media Channels" examines how the three telecom operators dominating the Czech market - T-Mobile Czech Republic, O2 Czech Republic and Vodafone Czech Republic - use the digital media channels within the communication with the customers. More specifically, it identifies and describes which channels do the companies involve into their marketing communication, how do they use them and why they have integrated them into the communication strategy. It also examines how the companies interconnect these digital media channels and how the channels can be combined to form an effective digital media strategy. By using the method of case study the companies ' digital marketing activities were examined. It was found that each company uses for its marketing communication the similar set of digital media channels, but the usage is different across the companies studied. Based on these findings I have identified three specific strategies - Diversified Content Strategy, Interactive Channel Strategy and Standardized Content Strategy. Each of the strategies has its advantages and disadvantages, which have been described and the strategies were compared. The findings also indicate that it is better to study the digital media channels as a whole,...

Oligopolistic Competition in Selected Market Segment
Daněk, Lukáš ; Svoboda, Roman (advisor) ; Severová, Lucie (referee)
Telecom market in the current Czech Republic is one of the worlds decisive but also the most profitable sectors of globalized economies. The mobile communications market in the Czech Republic now hosts many operators, however its development determine only three network operators and one market regulator, the Czech Telecommunication Office. Major providers of mobile telephone services in the Czech Republic are TMobile, O2 and Vodafone (94% market share in the Czech Republic). Less important place in the market occupy virtual operators whose market power is relatively small and they are unable to be considerably ahead in terms of oligopolistic competition on the domestic market. Those matters correspond to the model of an oligopolistic market with dominant firm and competitive fringe. In the Czech Republic this competitive fringe consists of two powerful companies and a large group of virtual operators, who, however, make up only 6% of the market. Said (oligopolistic) structure of the mobile communications market in the Czech market thus appears to be stable over time; the position of dominant firm TMobile may possibly be replaced by O2 in the long term.

Myšková, Marika ; Zeman, Jiří (advisor) ; Filipová, Alena (referee)
The aim of this thesis is to evaluate the process of introducing unlimited tariffs by O2 Czech Republic a.s. as to the Czech telecommunications market. The focus of this topic has two perspectives, perspective of the innovative companies and competitors' view. In the assessment perspective, there is also the view of customers. In the first part, I have dealt mainly with the general theory of introducing innovative products to the market, which is related to business surveys that were conducted, in particular the analysis of competition and the market. In the practical part, I focused on the very process of implementation, including the initial assessment of the market situation, setting pricing policies or communication tools that were used. In conclusion, I compared previous expectations with real impacts.
