Use of Radio Network to Provide Supervisory Control of E. ON Power Network
Fazekas, Tamás ; Flasar, Václav (referee) ; Baxant, Petr (advisor)
The aim of this master´s thesis is to find a suitable means of communication to provide supervisory control for the distribution network of the utility company E.ON. Comparison of a digital radio system, which would be in the property of the company and of the radio systems of mobile operators is done. In this work the reader gets familiar with the structure of the distribution network of the utility company E.ON and with the scope of activities of the grid controller. The reader also gets acquainted with the current state of the radio system of the E. ON, and with the requirements, which should be fulfilled by them. An important part of this work is formed by the description of the possibilities of the private radio systems and mobile operators. At the end, the possibility of the private radio systems and systems of mobile operator usage in the Smart Grid system is given.

Position navigation system with GSM interface
Pristach, Marián ; Khatib, Nabhan (referee) ; Kadlec, Jaroslav (advisor)
The objective of the diploma thesis is to design a device for positioning of mobile devices using GPS satellites. When coordinates are acquired they can be sent via the GSM network to a user's cell phone or to an SQL server. A web interface has been designed to access the stored data and to show the current device position and the history. This position datalogging system can be used for monitoring vehicles as well as a security system for cars.

Convergent Mobile Technology Solutions for Corporate Customers
Stančík, Michal ; Tomek, Martin (referee) ; Kříž, Jiří (advisor)
Bachelor’s thesis deals with ways how to use convergent solutions of mobile technologies as benefit for corporate customers, especially small real estate agency. Theoretical area describes basic voice and data transfer’s principles and technologies in mobile networks. Second part analyse key working processes and tries to reveal deficiencies in current real estate agency’s telecommunication system. Practical proposal shows how to remove discovered deficiencies by adjustment of key working processes and afterwards apply the most useful functionalities of convergent solution. In the end there is a costs comparison between current and suggested telecommunication system.

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.

GSM Module for Wireless Sensor Networks
Mayer, Jan ; Janoušek, Vladimír (referee) ; Horáček, Jan (advisor)
Main goal of this project is to achieve communication between user and distant wireless sensor network using GSM technology. This task will be accomplished by connecting Crossbow Iris wireless sensor node and Teltonika GSM module device. Communication itself will be provided by sending/receiving SMS and connecting platform to remote server over the internet using GPRS technology.

Car Localization Using Satellite Systems
Uhliar, Martin ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
This bachelor thesis deals with the design, hardware and software implementation of a location device which can get a location data and speed of a car on the Earth's surface. Through the GPRS mobile network, the obtained values are transferred to a remote server and then stored in a database. This data is presented to the user via a web application that displays the current location of the car on the map. The device is controlled by ARM microcontroller.
