Hi.
as far as i know, uplink and downlink of LoRaWAN is IQ inverted. so, uplinks are not affected by downlinks like collision, right?
Correct, and even when there are multiple uplinks/downlinks at the same time, it’s still very likely (especially when using different data rates) that those concurrent transmissions can still be demodulated properly.
Of course, as gateways are not full-duplex, they are not able to receive any uplinks while they are transmitting downlinks.

Hi,
and a node can listen only I/Q inverted signal so packets from a certain node can not be received by other nodes?
simply, can they just demodulate only downlinks?
