LoRa Gateway
Očenášek, Matěj ; Janůš, Tomáš (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the implementation of two LoRaWAN systems and the creation of instructions on how to put these systems into operation. Both systems consist of a end device, an access gateway, a network and application server, and a website to display the data obtained from the end device. The public network "The Things Network" and the local network ChirpStack are used to implement these two systems.

Impact of Communication Parameters on Energy Consumption of Zigbee Devices
Popelka, Jan ; Červenka, Vladimír (referee) ; Šimek, Milan (advisor)
This thesis deals with the energy research and design a simple wireless sensor networks. The data modules with ZigBee wireless communication technology. The main feature of wireless sensor networks is the minimal energy devices at low cost and maximum data reliability. Furthermore, the work describes firmware for communicating nodes with the ability to change parameters of data transmission and thus affect the energy consumption node. Calculations of energy consumption, compared with measured results and discharge characteristics of the battery packs are included in the final chapters of this work.

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.

Virtualized web application for receiving data from sensors
Kharytonov, Oleh ; Fujdiak, Radek (referee) ; Pospíšil, Jan (advisor)
At the beginning of the theoretical part, the bachelor thesis focuses on LPWAN or Low-Power Wide-Area Network technology. Systems that are characterized by low power consumption and wide coverage. Their key features are discussed. Subsequently, attention is paid to the LoRaWAN\texttrademark\ standard,. Initially, LoRa\textsuperscript{\tiny\textregistered} modulation is discussed - the modulation techniques used and the advantages over competitors. The next step discusses LoRaWAN\texttrademark\, - architecture, types of end devices and security. Virtualization - uses in today's world, discusses types of virtualization and its benefits. The practical part introduces the commissioning of open-source LoRaWAN\texttrademark\, ChirpStack server, gateway, endpoint registration and activation. Attention is paid to an application programmed using Flask for device management and data reception. The principle of operation and commissioning of the virtualized web application is explained. Finally, the results and possible ways to improve the application are described.

Applied automation between security network components in operational networks
Škoda, Jakub ; Benedikt, Jan (referee) ; Kubánková, Anna (advisor)
Tato práce se zabývá studiem možností automatizace v síťové bezpečnosti. Identifikuje konkrétní manuální pracovní postup a navrhne možnosti, jak tento pracovní postup zautomatizovat a tím nahradit zastaralý manuální postup. V novém automatizovaném pracovním postupu byly použity nástroje Cisco Umbrella pro hlášení a hodnocení DNS pro koncová zařízení. Tyto nástroje byly použity k vytvoření nové bezpečnostní metriky – chování. Chování koncového bodu se pak použije u vybraného případu použití vzdáleného přístupu VPN. Namísto použití compliance kontroly před navázáním připojení VPN, se použije chování koncového bodu.

Monitoring and Security System
Felix, Martin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.

Wireless electronic security and surveilance system
Vichta, Michal ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
This bachelor thesis is engaged in proposal and implementation of wire less safeguarding system. The proposal is consisting from study of single components wire less safeguarding system like for example: detectors, central, GSM communicator and mobile station. The bechelor is engaged familiarization of technologies for formation sensing element networks and proposal (principal) diagram wire less systém of familly house. For realization wire less network is exploit standart IEEE 802.15.4 ZigBee on a frequence 2,4 GHz and radio outside on a work frequence 868,3MHz. Beside terminal arrangement and near co-ordinator is exploiting Zigbee program units from Meschnetics company too. Next to radio outsider is exploiting wire less base extension station from Satel company. Both of wire less are connected with a central of wire less safeguarding system and conseguently connected with GSM communicator from Satel company, whitch on is concernig abouth sendings of messages abouth loom of wire less safeguarding system towards to user on mobile station.
