Wireless IR Sensor for Area Invasion Detection
Suchý, Lukáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The target of this Bachelor thesis to design a security system for detection of the monitored space disruption, containing several battery powered sensors which are connected to central unit. From Bachelor thesis is evident, that for communication is to be used integrated circuit SI4432. Sensor detects motion in distance no less than 5 m and sends reports of the space disruption to central unit where this information will be processed. After that the user will be informed by the central unit. Sensor unit should be battery powered with lifetime in years. In conlusion, the system it tested in real work.

Localization in LoRaWAN technology
Pospíšil, Jan ; Hošek, Jiří (referee) ; Fujdiak, Radek (advisor)
The diploma thesis in theoretical part focuses on LPWAN in general, meaning the low power wireless device falling into IoT category with a focus on LoRaWAN. The second half of the theoretical part focuses on describing localization techniques and principles in general and selection of one suitable technique for implementation in LoRaWAN. The practical part focuses on the proper HW customizations to enable the localization in this network. There are also described all the steps needed to build the whole working LoRaWAN network. The TDoA localization algorithm is described, the functionality is verified by simulation and also by testing under real conditions. In the end, the results are explained, the shortcomings of the technology are described and finally a suggestion for improvement is provided.
