Local Positioning System based on LoRa Devices
 Holík, David ; Burian, František (referee) ; Arm, Jakub (advisor)
The work deals with wireless communication using LoRa (Long Range) technology categorized as LPWAN (Low Power Wide Area Network). The technology enables wireless data transmission over long distances more than 5 kilometers in urban or rural areas. The technology is used as the communication between ESP32-based devices providing their GPS data and time synchronization. The system also consists of Raspberry Pi which provides the central LoRa station for near area. It is running the LoRaWAN server called ChirpStack. The communication between central and peripheral devices was established using open-source libraries. Moreover, the communication with the public TTN network has been tested. Regarding the communication testing, test scenarios were designed, based on which the corresponding measurements were performed. The results were presented and evaluated.
