V diplomskem delu opišemo hitro rastoče področje IoT in podrobneje pregledamo eno izmed tehnologij na tem področju, tj. LoRaWAN, ki temelji na LoRa modulaciji. LoRaWAN zaradi svojih prednosti postaja vse bolj priljubljena, saj združuje fleksibilnost protokolov, ki jih uporabljamo predvsem na lokalni ravni (npr. Bluetooth in WiFi) ter dometa mobilnih omrežij (npr. GSM, 3G, LTE itd.). Ob vseh teh lastnostih imamo še izjemno nizko porabo energije, kar omogoča, da merilne naprave montiramo na oddaljena mesta brez stalnega vira napajanja. Te naprave oziroma senzorji nam omogočajo spremljanje želenih vrednosti iz okolice. Meritve se s pomočjo prehodnih naprav pošiljajo v zaledne strežnike, kjer se podatki shranjujejo. Cilj diplomske naloge je realizacija takšnega omrežja za potrebe nadzora in upravljanja kmetijske plantaže. Prikazana je izbira komponent rešitve, opis postavitve takšnega omrežja in opis delovanja rešitve. In this thesis we describe fast growing IoT and take a closer look at one of it’s techonologies, LoRaWAN, which is based on LoRa modulation. LoRaWAN is gaining popularity due to it’s advantages, as it combines the flexibility of protocols mainly used as local networks (e.g. Bluetooth and WiFi) and range of mobile networks (e.g. GSM, 3G, LTE etc.). In addition to all these features, we also have extremely low energy comsumption, which allows us to install measuring devices in remote locations without permanent power source. These devices, usually refered as sensors allow us to monitor desired values from the environment. The measurements are sent via gateway devices to back-end servers, where the data is stored. The aim of this thesis is the realisation of such network for the needs of control and management of agricultural plantations. It shows how to choose components of the solution, how to set up such network and describes how the system operates.
