Well, Jim stated that XPS will retransmit up to 3 times, when the module does not get the acknowledgement from the reciever, right?
So, how can it happen, that the ack is not recieved? Certainly by interference: Either the reciever did not get the information due to interference, or the module does not recieve the ack due to interference.
The result is: Upon the encounter of other signals (interference), XPS will not stop transmitting. It will do the opposite: Retransmitting packs as often as possible.

Have you read the article in RC Elektronik "2.4 GHz und die Geheimnisse einer neuen Technologie" ?
No, I have not. It sounds like a magazine, or do you have a link?
