Wireless sensor networks for environmental monitoring
Mizera, Josef ; Červenka, Vladimír (referee) ; Morávek, Patrik (advisor)
his work is focused on usability of wireless sensor networks for monitoring environment. Wireless sensor networks are used more and more for this purposes. This technology has great advantages in comparison with cable networks, mainly in difficulty of their realization. This work contains a description of wireless sensor networks, norms and specifications used for these networks. Requirements on software processing data from sensors and how the signal is distributed. There are examples of applications where wireless networks are used. The reasons why these networks began to be used and in what way they eased the work in such area or problems that are solved by these networks. In the last part of my work is a design of application for monitoring of forest fires in area of Komonec by using wireless sensor networks where it should be beneficial.

Suggestion of changes of infrastructure of network for RAAB Computer
Brázda, Ondřej ; Raab, Ladislav (referee) ; Ondrák, Viktor (advisor)
The target of this work is focused on relocation of important backbone node of network and implementation of internet signal to villages that are accessible with difficulties. The reason why the backbone node has to be relocated is because the building where the backbone node is located will be demolished. On the basis of this thesis the company should be able to realize changes in its network. In the theoretical part of this thesis I am going to deal with possible problems in transmission of internet signal.

Measurement of the near field distribution
Macháček, Ivan ; Tkadlec, Roman (referee) ; Nováček, Zdeněk (advisor)
The aim of this work was to prepare measuring workplace, perform the verication measurement, including the measurement phase, on the cylindrical surface. Measured data were compared with theoretical assumptions and were calculated directional patterns. Probes for measurement in the near sield were designed and realized.

Benchmarking Performance of WiFi Networks
Hrabčak, Miroslav ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
This bachelor project discusses throughput problems of the WIFI networks. Project analyzes typical problems and factors, that affect decrease of their capacity and concentrates on typical problems of their signal path. Describes techniques of monitoring, detection and debugging causes, which affects decrease of network throughput. The project also includes the experimental testing and analyzes of standards 802.11b/g and 802.11n on the labs WiFi network.

Line of sight testing
Lutka, Adam ; Skopal, Tomáš (advisor) ; Hoksza, David (referee)
A measurement done for every possible wireless data connection is expensive. It would be useful to reduce the cost. An application which could determine a quality of circumstances influencing possibility of a connection would help to do such a cost reduction. The thesis provides such an application which gives user information about meaningfulness of a real measurement in specific situation. Powered by TCPDF (www.tcpdf.org)
