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.

Wireless Security Audit
VRÁTNÝ, Jan
This bachelor thesis deals with security problems of wireless networks, also known as Wi-Fi. The purpose of the thesis is to explain the concept of Wi-Fi network, from what components it is composed, introduce safety devices used in wireless networks, and perform a research in a selected city in a specific location with the largest concentration of people if the wireless networks are secured and if they are what type of security is used. In a domestic environment an illustrative attack will be made on a Wi-Fi network secured by 128-bit WEP key. Also I will describe a new security bug that was discovered at the WPS function. Furthermore, this bachelor thesis will focus in detail on a local business, which in addition to conventional LAN extensively uses Wi-Fi network. An analysis of the security of the Wi-Fi network will be performed and the results will be evaluated to show the economic impact on the company if it were to be subjected to an attack in which sensitive data are leaked.

Design wireless network in the company including radio survey
Kopecký, Matěj ; Pavlíček, Luboš (advisor) ; Šolc, Jiří (referee)
My bachelor thesis focuses on IT infrastructure of business environment, followed by a proposal of solution (deployment of transmitters, connection to existing infrastructure, budget), which is complemented by real deployment of typologically similar or same solution, including radio surveys before and after the deployment. Thesis is divided into several parts. Introductory chapters deal with theoretical concepts, definitions and standards that are important to become familiar with the topic. Theoretical part is followed by practical part that contains detailed information on above sections. Goal of my thesis is to propose the most effective solution for specific organization. In this paper I'll try to avoid all known usual problems and errors. I'd like to achieve this thanks to my long experience with wifi as I've for several years run a wireless network with more than 600 users.
