Emergency Button for Seniors
Verbík, Josef ; Chmelař, Milan (referee) ; Strašil, Ivo (advisor)
This Thesis „Emergency Button for Seniors“ is about suggestion of realization of system emergency signalization. The System consists of programmable digital watch with wireless interface and PC with software processing signals. Status signalization is created by phone message and figuration of dialog on monitor. There is used free software for realization. Operation system on PC is Linux (distribution Ubontu 11.04). For graphic transitional plane PC application is used cross-platform framework QT. For watch firmware is used C compiler MSP430-GCC, MSP debug v0,15 and firmware OpenChronos.

Data collection by wireless technology ZigBee
Teplan, Miroslav ; Burget, Radim (referee) ; Koutný, Martin (advisor)
This bachelor study deals with communication standard IEEE 802.15.4, wireless technology ZigBee and describes its using in collective data collection area and telemetry. Teoretical part is formed by some chapters which detailing standard IEEE 802.15.4 and ZigBee technology and some chapters which detailing communication unit design from look peripheral solving and implementation firmware. Practical part have to do with itself realization communication unit for data gathering from measuring devices. It is based on circumscribed solving. Further smoothing - out proposal frame system in which the would be used technology ZigBee.

A new security model implemented in the metropolitan network
Dančuk, Michal ; Kyselák, Martin (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis deals with wireless computer networks in a point of view security. It contains security principles and standards used in these networks. It shows failings of old security methods in contras of new standards. The result of the thesis is a design of the metropolitan network and its realization. In this network appropriate solutions of security are used. The last part of the thesis deals with a design of web applications created in the PHP programming language and SQL database system.

Laboratory development kit for wireless networks
Marák, Jiří ; Caha, Tomáš (referee) ; Krajsa, Ondřej (advisor)
The aim of this work is to design and implement a laboratory development kit for teaching wireless networks based on IEEE 802.15, IEEE 802.15.1, IEEE 802.11 standards and similar technologies. First are described WPAN and WLAN wireless technologies. In the next part, the work deals with the overall concept of the development kit and the subsequent selection of suitable components, and finally the design of its own development kit and the design of the printed circuit board in the program Autodesk Eagle.
