Building and using smaller computer networks
Ďurica, Matej ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
In these days, the widespread creation of home networks, due to the continuous development of computer technology for personal use. These networks are formed, for example, with the aim of facilitating access to information, ease of communication between people and control of various devices in the home. Their development is influenced by trends in information communication technologies in the market. This bachelor thesis is fully focused on the practical implementation of the proposal for extension of the original smaller home network using the new network elements (wireless routers, switches, network printers, NAS server, device for live monitoring of security cameras) and rendering certain network services (DLNA, print server, VPN, iTunes server, live monitoring of security cameras). A given network was tested with respect to performance network and its response, coverage of Wi-Fi signal, testing remote access, power consumption, read and writes speed of the NAS server.

Building and use of small computer networks
Nepomucký, Pavel ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The thesis deals with design of small home network. The main goal is to describe extending home network by new network components, which allow users in specific areas to use newly created wireless connection. The thesis is split into two parts. The first one is given for explanation of network components and their comunication. Second one describes practical demonstration of extending home network by a new component providing wireless conection. The thesis decribes a selection and analysis of network components including setting up, coverage and communication between each access point.

Design and security of small wireless network
Cikánek, Svatopluk ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This thesis deals with design and security of small wireless network and providing selected network services. The thesis is divided into four main parts. The first part is dedicated to theory of networks and looks into metallic and wireless networks and functions of some network components. The second part describes current network in dwelling-house and its network components. The third part deals with network design, innovation, choosing of components and their settings. The last part is devoted to providing network services, their settings and attest.

Building and use of small computer networks
Pecka, Jiří ; Pinkas, Otakar (advisor) ; Palovský, Radomír (referee)
The thesis deals with a new design for the home network according to the given requirements of its users. The main aim is to describe how the network can be expanded to include other elements to allow users to access the Internet, data storage and other services via wireless networks in selected locations. The thesis it divided into three parts. The first part describes the previous state of the network and users' requirements for improvements. The second part describes the network and device settings. The third part is devoted to the network testing, including evaluation of the signal strength of access points in all areas of the selected sites and attack simulation on the access point.

Building and use of small computer networks
Zitta, Vladimír ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
Bachelor thesis deals with the design, construction and testing of a home computer network. The first part is theoretical and is devoted to network elements, protocols and standards that will occur in the home network. The second part is practical and deals with the main aim of the text, designing extended home network and it's implementation. Described are selected network elements, configuration, network services and subsequent testing of the network.

Computer networks, theirs security and overcoming of that security
Zikeš, Tomáš ; Přibil, Jiří (advisor) ; Bína, Vladislav (referee)
Main goals of this diploma thesis is to chart methods used to secure wireless internet networks a test those methods through attack on access point of wireless network with target to receive password to access this network and decryption of captured packets. For charting of types of security measures used for wireless network, I performed a series of measurements in field on different places in Czech Republic and Germany. Primary purpose of mesurements performed in Germany is caomparison of results from Germany with results from Czech Republic. Also, I tried to crack the security measures i controlled environment. Due to illegality of this experiment I used my own network and network that belongs o one of my friends who agreed with the experiment.In the end is the presentation of results of field measurements and cracking attempts along with some tips for network security.

Renovace počítačové sítě ZŠ a MŠ Kanice
Kučera, Martin
The object of this bachelor thesis is a renovation of computer network at Elemen-tary School in Kanice. The task is to move the ICT classrooms and network ele-ments to the new floor. Another task is to lay out and create a wireless communication between buildings of the Elementary School. Final task of this thesis will be to create Wi-Fi for students, which will have a limited speed capacity. This thesis ends with the economical evaluation of the entire project.

WiFi Direct Technology and its practical use
STARÝ, Tomáš
The aim of this bachelor thesis is to determine the possibilities of practical usage of Wi-Fi Direct technology based on experimental verification which will be carried out using two mobile devices. Basic analysis of network properties will be performed on these two devices and the measured results will be compared with the theoretical values of Ad-hoc and BlueTooth technologies. We will determine where this new technology could be used in practice based on this comparison.

Design and security of small wireless network
Žižka, Ladislav ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This thesis deals with design and security of small wireless network. Main goal of the thesis is home network design and choice of optimal solution of wireless security. The thesis has four parts. The first part describes computer networks and network components in theory. Next part deals with network design, choosing of network components and setting of them. It also describes some functionalities of alternative firmware DD-WRT. The third part presents common wireless security and network analyzing software. In the last part there are proved some types of attacks against Wi-Fi networks with Aircrack-ng suite.
