LoRaWAN
LoRaWAN is suitable for long-range, low power applications such as smart agriculture, asset tracking and smart cities.
To maximize power savings on a LoRaWAN gateway or device, you can consider the following configurations:
-
Choose the appropriate device class. LoRaWAN
defines class A, B, and C device types. These device types have different receive window configurations that significantly impact the power consumption of a LoRaWAN device. -
Where possible use FUOTA (Firmware Update Over The Air) over multicast for efficient file transfer to many devices receiving the same firmware.
-
Choose hardware components, such as processors and radios, that have low power consumption to minimize energy usage.
-
Position the gateway antenna for maximum coverage and signal strength, to reduce the need for high transmit power.
-
Set the gateway to use a lower transmit power that still provides good coverage in the target area. This reduces energy usage and can increase the lifetime of the gateway.
-
Use Listen Before Talk (LBT) and Adaptive Data Rate (ADR) - these features can help minimize the number of retransmissions and collisions, which can reduce energy usage.
-
Configure the gateway to use the appropriate packet size and data rate for the application. Large packet sizes and high data rates can increase energy usage.
-
Configure the gateway to use deep sleep mode when it is not actively transmitting or receiving data. This can significantly reduce energy usage.
