1. A transmission method for transmitting a message from a first node device to a second node device belonging to a network neighbourhood of said first node device, said first and second node devices belong to an electrical supply network using powerline communications, the transmission method comprising, implemented by the first node device:
fragmenting said message into N fragments, N being a natural integer greater than or equal to 2;
associating, with the odd fragments, a first frequency band of a set of frequency bands comprising at least two frequency bands and associating, with the even fragments, a second frequency band of said set of frequency bands, said first and second frequency bands being different; and
transmitting said odd fragments on the first frequency band and said even fragments on the second frequency band in response to the odd and even fragments being associated with the first and second frequency bands, respectively, so that the odd and even fragments are transmitted on different frequency bands,
wherein the transmission method further comprises the following step performed by said second node device:
receiving each of the N fragments on the frequency band with which is associated with each respective said N fragments; and
reassembling said N fragments to reconstruct said message.
