LoRa Wake-up Radio Relay with BeagleBone Black
Disciplines
Systems and Communications
Abstract (300 words maximum)
This project investigates the use of BeagleBone Black Wireless single-board Linux computers with Long Range (LoRa) transceivers to send and receive information while using a relay in the system. Three experiments are conducted. The first is conducted by maintaining the size of the payload and the distance between LoRa transceivers. The spread factor, bandwidth, coding rate, and output power are all varied. The second experiment has the LoRa relay system listening to the transmissions between two LoRa transceivers and only transmitting if the received signal is less than a certain strength level. The third experiment combines the LoRa relay system with a wake-up radio, optimizing power utilization. The LoRa relay learns the transmission interval and goes to sleep in between transmissions. Python code, data from the experiment, and conclusions are provided.
