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.
