Claim 6:
7. An electrical supply network using powerline and/or radio-frequency communications, said network comprising at least one first node device configured for transmitting a message according to a so-called hyper-robust mode to a second node device of said network belonging to its network neighbourhood, said first node device comprising at least one processor configured to:
transmit said message to said second node device on a first frequency band of a set of frequency bands comprising at least two frequency bands, said message being modulated according to a robust mode, a modulation according to said robust mode comprising successively a Reed-Solomon coding, a convolutional coding, a coding by code repetition and a BPSK modulation; and
transmit said message, to said second node device, on at least one second frequency band of said set of frequency bands, said message being modulated according to said robust mode and said first and second frequency bands being different;
and said second node device comprising at least one processor configured to:
receive said message on said first frequency band and on said second frequency band;
deduce therefrom that the first node device is configured according to the hyper-robust mode;
change its own transmission mode into the hyper-robust mode in the case where its own transmission mode is different from the hyper-robust mode;
transmit, to said node device, an acknowledgement message on said first frequency band and an acknowledgement message on said second frequency band.
