IEEE 802.15.4 range measurements
Komadel, Lukáš ; Hynčica, Ondřej (referee) ; Fiedler, Petr (advisor)
In the master’s thesis IEEE 802.15.4 Range measurements I want to find out, whether atmospheric conditions have influence over the quality of communication between two ZigBee modules. I would like found the answer by long-time test, because I can’t found the proper place for the measuring, I must found the answer in the literature. In the second part of the master’s thesis I measuring, whether placing one of the module in the car have influence over the quality of communication. The module was placing in the various places in the car, on a dashboard, on a guest-passenger’s seat, in a pocket before guest-passenger and in luggage compartment. The car for the measuring was used Renaul Scénic my. 2004.

Software tester of embedded module communication based on AT commands
Kondr, Aleš ; Prokeš, Aleš (referee) ; Kubíček, Michal (advisor)
The graduation thesis deals with AT commands and the implementation of these in modules of wireless communication. These commands are mainly used for the obtaining and setting of different parameters of such modules. A form of the AT commands and a manner in which these are sent to modules are described. For selected wireless modules, there is a set of AT commands determined together with a brief description of the functions of these. A manner of creation of macroblocks for the TeraTerm program is also mentioned; macroblocks are able to establish communication with the module connected and allow for measurement and testing of communication appliances. This is suitable especially for the automation of such a process. As such a system (program) is not widely known, a thorough description of this system is given together with a description of measuring and testing macroblocks. The last part of the thesis deals with the creation of an application enabling the user to control quickly and easily an inserted appliance. A very detailed description of this application is given. Due to an absence of an advanced graphic interface, such an application has not been created by means of a system of macroblocks for the TeraTerm program, but it has been created in the JAVA programming language.

Wireless Security and Surveillance System
Výborný, Jiří ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
This Master’s thesis deals with design and construction of a wireless security and surveillance system in ZigBee wireless networks (IEEE802.15.4). The design consists of creating a star network topology with intended monitoring of home area via end device boards paired with coordinator board, which provides basic networking functionality. End device is used to send data from a temperature sensor DS1631 and magnetic reed switches to coordinator. ZigBee module ZDM-A1281-A2 made by MeshNetics company embedded on each board contains a micro controller ATMega1281 and a transceiver AT86RF230 working in a 2,4GHz frequency band. System is able to notice of any door or window move actions and too high temperature. The non-fully functional ZigBee stack, which is called an Open MAC software, based on MAC (Media Access Control ) layer and PHY (Physical) layer from MeshNetics, has been used to develop the user software. Open MAC consists of three application samples in C code. One of them was modified by the user for an application of communication between the module and sensors. The same design with module RC2204AT made by Radiocrafts company was tested as well, but it couldn’t be executed. All developed boards have been constructed and tested via Terminal PC program.

Wireless access system
Sekyra, Jaroslav ; Honzík, Petr (referee) ; Fiedler, Petr (advisor)
This diploma thesis describes practical realization of entrance terminal, which enables transmission of data thanks to radio module ZigBee PAN4551 and Ethernet module Rabbit RCM3200. This entrance system uses Mifare RFID cards, with whose user will identify at the entrance terminal of the guarded object. Data are sent to server station by radio module ZigBee or Ethernet module Rabbit during demand of entrance. The database of all entrance rights of all users is stored on this server. Data system works up received data and sends them back to the terminal. One part of these data is the information about enabling of user entrance. The database system makes a list of passing through users. In the first part of this work whole conception of entrance terminal is suggested. Then basic demands of each block are described in details as well as their placement in guarded object. Next chapters describe basic function of terminal, electrical scheme, and system of power supplies for the access system. Also individual hardware components are chosen and described. In the on of the last chapter there is flow-process diagram of main loops for individual variants of terminal and interrupts functions from timer, serial link and external input from radio network MC13193 drawn. In the last chapter there is a show of server data application “AccessServer” and his basic description.

PDA software for robot soccer
Uhlíř, Luděk ; Honzík, Petr (referee) ; Hrabec, Jakub (advisor)
Robotic soccer is a game like a real soccer but here the game is played by robots. The rules are the same, only there are few exceptions (foul, penalty kick, stalemate situation). Game is running without the human intervention. Just a human referee is supervising the game. Two teams are attending the game. Each of them has a control computer. The control computer is the brain of the game. It has a camera, it is making decisions for the next step of robots and sending them configuration data. The thesis deals with testing of communication interface and designs the new communication protocol for the next generation of the robots. The testing is provided by pocket pc Palm TX. It will send data over the Bluetooth interface to the control pc and will configure particular constants, like constants of PID regulator and an address of a robot. This will be provided by the IrDA interface.
