ATIM_ACW-LW8-GW_UG_EN_V1.1
Operating mode
L’ACW/LW8
-GW is a LoRa / LoRaWAN repeater that works exclusively with ATIM devices.
Operating principle
When an ATIM device is not able to join the LoRaWAN network (private or operated), the ACW/LW8-GW repeater
allows to overcome this issue.
Figure 1 : operating principle
The ATIM product that must be repeated must be an ATIM product that is compatible with this repeater (see Limitation
chapter to check the product compatibility).
Instead of going through the LoRaWAN network to send its business frames, the product that does not have access to
the network will then modulate its LoRa messages to a repeater placed nearby. A local point-to-point communication
is then established between the product to be repeated and the repeater.
As soon as the repeater receives a local frame, it transfers it to the LoRaWAN network that it previously joined: that
way, the frame of the product is well modulated and received on the LoRaWAN network.
