Dear Rack team,
In this question, I understand that LBT for LoraWAN is V4.0.0.
When do you plan to support LBT for P2P?
CAD or LBT (not sure what will be used) is on the list for the next RUI3 version.
Basically they do the same, but with different methods.
CAD - Channel Activity Detection - is listening on the requested send frequency for any activity and returns whether the frequency is in use or not.
LBT - Listen before Talk - is checking the RSSI levels on the requested send frequency to see if there is any activity.
I think the LoRaWAN stack implemented LBT because not all LoRa transceivers support CAD (I know the SX1262 supports it)
beegee Thank you for your reply.
Will LBT support in this way?
Sorry for the Japanese site.
If my Google translation is correct:
It supports the LBT (Listen before talk) function. LBT refers to how a device enters Rx mode and checks for interference signal levels before it starts transmitting.
That is exactly how we are implementing LBT.
