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.

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.

The availability of mobile internet access in the Czech Republic
Michel, Milan ; Sigmund, Tomáš (advisor) ; Toman, Prokop (referee)
This work is focused on the internet access availability via mobile connection. Technologies being used or available on the Czech market are discussed. The current products offered on the mobile internet connection market for end users are featured. Products being suitable to representatives chosen with regards to the opinion poll are recommended. Conditions on the Czech market are compared with the market of a representative chosen among the advanced members of the EU. Eventually, possible developing trends and further recommendations are discussed.
