I just found this:

Hi everyone,
I am not sure to understand the difference between LoRa module and LoRaWAN module... I first thought LoRa was for end clients and LoRaWAN for the gateway.
But then I saw in the example code there is LoRa<>LoRa communication.
I am quite lost.
Let's say I want to have a dozen sensors and one gateway. What modules should I buy ?
Thanks is advance,
