Implementation of USB/LAN/WIFI interface
Voneš, Jaroslav ; Roubal, Zdeněk (referee) ; Steinbauer, Miloslav (advisor)
This bachelor thesis goes into implementing the most modern communication interfaces USB/LAN/WIFI to control the computer itself and also the incubator via a Web interface. The term describes the overall solution to the management of the incubator for using microcontroller ATmega8 with the possibility of the exchange of communication interfaces. For the USB converter was used the circuit FTDI FT232 BM company, from LANTRONIX Ethernet was used for Converter converter XPORT and eventually to communicate the WIFI was elected circuit ESP 8266

Wireless local network detection device
Procházka, Miroslav ; Beneš, Jan (referee) ; Prokopec, Jan (advisor)
This thesis deals with Wifi and presents proposal of device for wireless network detection working in free of licence band 2,4 GHz. This work is devided into two parts. First includes a description of standart IEEE 802.11, it's apendix folowed by a description of physical and connection layer and wireless network security. In this part, basic principles of Wifi networks are explained. The second part of the thesis concerns a proposal of device for wireless networks detection. The second part also includes a list and description of used components and flow diagram, that illustrates an algorithm for wireless network detection.

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.

Quality of service support in unix-like operating system for communication in WiFi networks
Mizera, Josef ; Komosný, Dan (referee) ; Novotný, Vít (advisor)
Diploma thesis is focused on the supporting of Quality of Services in wireless networks, especially in the Linux operation systems. The topic is connected not only with OS, but also with the wireless standard, which supports QoS in wireless networks called IEEE 802.11e. QoS is needed especially for time-consuming data transfers in real time. The theoretical part deals with the theoretical analysis of the issue of the QoS support. There are described parameters, which occurred in quality of services support. This section also deals with the division of services that are used to transmit data across computer networks. It also describes the QoS support in wireless networks according 802.11e, its implementation and methods of accessing a medium with a without possibility of traffic. This part is followed by a description of QoS support in UNIX operating systems. The chapter describes how is the QoS support designed in these operating systems. There are also characterized concrete tools which are used for control the data flow in the operating systems using Linux. At the end the theoretical part deals with different types of queues and methods used in linux OS. In the practical part of the thesis, there are various designed topologies and scenarios to verify the functionality of QoS support in wireless networks using a Unix system. These chapters show the results of different tests at selected transmission data streams that are sensitive to transmission time. There is also verified cooperation of QoS support between devices operating on the network and data link layers. The output of this work is to design a laboratory exercise for the subject Network Architecture. This exercise is focused on familiarization with the QoS support functionality in wireless networks and in Unix-like operating systems. This chapter also describes the devices and programs that are needed to measure this task. The last part of the chapter describes the procedure for the preparation of the measuring station. For this laboratory task, there is an inserted manual in the annex.

Wireless Communication for Home Automation
Sezima, Václav ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
This bachelor's thesis deals with the issue of wireless communication among devices and sensors for home automation. The goal is to design and implement a device known as the gateway that is passing messages and commands between sensors and controller that controls them from central point, e.g. computer or mobile phone. A part of this thesis is also a creation of several sensors for the purpose of testing and demonstration. The gateway and sensors are based on development boards WEMOS and Arduino and supports multiple wireless technologies for communication with among themselves and controller.
