Introduction

This application note describes the power consumption profile of the WLR089 device under various application scenarios in Long Range (LoRa®) technology. The profiling of the WLR089 device captures various application scenarios based on the following connection types:

  • Long Range Wide Area Network (LoRaWAN) (Node <-> Gateway <-> Network Server)
    • Initialization
    • Join Procedure
    • Uplink Data Transmission
    • Downlink Data Reception
    • Sleep Mode Operation
    • Persistent Data Server (PDS) Operation
  • LoRa Modulation (Node to Node)
    • Data Transmission
    • Data Reception
This application note:
  • Helps the user to estimate the expected power consumption in the WLR089 device based on their tailored application needs
  • Details the setup to perform the power measurements using the WLR089 Xplained Pro Evaluation board. This is also a reference to estimate the power consumption with the custom board (using the WLR089 device) in real life applications.
  • Briefs the configurable parameters in both the LoRa connection type and the LoRaWAN connection type. The user can fine tune these configurable parameters to optimize further.
