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.

Recognition of security issues in LPWA type networks
Shestopalov, Artur ; Pospíšil, Jan (referee) ; Pospíšil, Ondřej (advisor)
The bachelor’s thesis deals with the issue of recognizing security incidents in LPWA (LowPower Wide Area) networks. Thesis contains information about the most used LPWA technologies, examines their security architecture and possible threats. Part of the work is a detailed description of LoRaWAN protocols, including architecture, possible attacks, distinguishing security architecture in the new and old versions. Work contains implementation of two security incident scenarios and their subsequent detection: jamming and gateway disconnection. As part of the detection, was created a web application that is able to detect real-time security incidents based on the average value of RSSI (Received Signal Strength Indicator) and the expected time of message transmission.

System for LoRa Devices Management
Štolfa, Filip ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The main goal of this thesis is to simplify the management of IoT devices in the LoRaWAN ecosystem and enable seamless migration between two central LoRaWAN servers. Two LoRaWAN network servers—ChirpStack and TheThingsStack—are described in this thesis. Based on user requirements for a smart city management system an application is designed and implemented that can communicate with these servers and offers users a single interface to manage devices on these servers. The device data is first stored in the application database and then synchronized with the selected LoRaWAN server using the provided application interface. The solution is implemented as a web application using the Angular application framework. The backend is implemented using the Express.js application framework and the AWS Lambda platform.
