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.

Wireless temperature sensor with high temperature warning indicator
Dvořák, Petr ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
This thesis deals with a proposal of a wireless temperature-sensitive element at high temperature. It analyses some different variants of the temperature sensors. Furthermore, the thesis describes the Industry Science Medical (ISM) bands, in which it will be possible to communicate with the wireless communication modules. These wireless modules are discussed and described. By the devices „the transmitter and the receiver" it is focused on the communication of the microcontroller Atmel with the wireless modules, with the temperature sensors, microswitches on the control and display unit (LCD).
