The objective of this thesis was to provide a detailed theoretical breakdown of LoRa technology, in particular the 433Mhz band, and demonstrate possibilities regarding data rate optimization for LoRaWAN.
The work came out of a SES Lab project at Etteplan that utilized LoRa communication, as well as the company’s general interest in learning more about the 433Mhz LoRa frequency band. Equipment for testing such as the LoRa end node and gateway were provided by Etteplan. The end node was programmed with a modified Mbed LoRaWAN example application (C++) and Python was used to create a script to log all uplink LoRa messages going from the end-node to The Things Network. Data was collected from three tests with varying conditions.
In the end, the project was a moderate success. Although not all the tests were successfully implemented due to technical limitations, the paper successfully provides a detailed understanding of LoRa technology both in a general sense and in the context of the 433Mhz band. The tests helped further illustrate how different factors can affect data rate management for LoRa applications.
