@sergiosena OK, glad you proved part of my idea's about the RN2483 to be wrong 
Actually I had been looking for this also and even skimmed the thread you mentioned above. Because of the post by @nestorayuso who I consider to be one of the experts in the field, and the direction the thread took (mostly talk about gateway based solutions) I didn't even bother trying 
Is there a description about the (single channel?) gateway you built using the RN2483?
