Design and experimental verification of broadband wireless technology using long-range modulation
Pospíšil, Ondřej ; Mlýnek, Petr (referee) ; Fujdiak, Radek (advisor)
This bachelor thesis deals with the use of wireless Low PowerWAN technology LoRaWAN in IoT. The thesis also describes both the physical layer on which the LoRa modulation works and the LoRaWAN protocol with its limits. The main goal of thesis was to design and realize network on LoRaWAN technology. The functionality of this network is verified in several scenarios in real traffic.
Wireless sensor based on LoRa technology
Pospíšil, Jan ; Krajsa, Ondřej (referee) ; Troják, David (advisor)
The bachelor thesis in theoretical part is focused on wireless technologies used for home control and automation devices where low power consumption is required. There are mentioned possibilities of each technology, energy requirements, range and throughput. The result of practical part is design and construction of a wireless temperature sensor which uses LoRa technology to communicate with a gateway and is also capable to last on battery for years. Additional feature is user possibility to use GPIO pins in form of relays. The task also covers design and construction of a gateway which listens for LoRa packets and communicates with PHP application on server side. Last step of practical part is focused on design of PHP application, which is responsible for visualization of received data.
Design of complex sensor node for LoRa network
Obrtáč, Tomáš ; Sova, Václav (referee) ; Chalupa, Jan (advisor)
This thesis covers development of complex sensor for LoRa network. The thesis is extended by theoretical section, which explains basic properties of Lora network. Theoretical section also covers analysis of software and hardware products on market. The practical part of thesis is focused on creation of complex sensor and development of complete server for its operation. In the hardware part is described method of choosing the right sensors, designing the PCB and description of important parts. Software development is described from acquisition of network server, through creating the computer application, to programming the MCU.
