Abstract
A transmission method makes it possible to transmit data from a first node device to a second node device belonging to a network neighbourhood of the first node device, the first and second node devices belonging to an electrical supply network. These nodes are configured for transmitting the data by powerline and by radio frequency. The method comprises the following steps performed by the first node device: distributing the data in two groups of data by an operation of interlacing the data, each group being associated with a communication medium from powerline and radio frequency, and transmitting each data item to a MAC layer of the communication medium associated with the group to which the data item belongs.

A transmission method for transmitting data 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 belonging to an electrical supply network and being configured for transmitting said data by powerline and by radio frequency, wherein the method causes said first node device to perform:
- distributing the data in two groups of data by an operation of interlacing said data, each group being associated with a communication medium from among powerline and radio frequency, and said operation of interlacing said data being carried out using either:
- (i) generating a first bit stream of N bits, each binary value being associated with one of the communication medium from among powerline and radio frequency, N being the number of data to be transmitted to the MAC layer, N being an integer greater than 0;
- permuting, by bit reversal, the bits in the first bit stream to obtain a second bit stream;
- and assigning each data item to the communication medium corresponding to the value of the bit at the same position in the second bit stream or,
- (ii) obtaining two interlacing tables, each interlacing table being associated with a communication medium and arranging the data to be transmitted within the interlacing tables;
- transmitting each data item to a MAC layer of the communication medium associated with the group to which said data item belongs.
A node device belonging to an electrical supply network, said node device being configured for transmitting data by powerline and by radio frequency to another node in said electrical supply network belonging to its network neighbourhood, wherein the node device comprises circuitry causing the node device to perform:
- distributing the data in two groups of data by an operation of interlacing said data, each group being associated with a communication medium from among powerline and radio frequency, said operation of interlacing said data being carried out using either:
- (i) generating a first bit stream of N bits, each binary value being associated with one of the communication medium from among powerline and radio frequency, N being the number of data to be transmitted to the MAC layer, N being an integer greater than 0;
- permuting, by bit reversal, the bits in the first bit stream to obtain a second bit stream;
- and assigning each data item to the communication medium corresponding to the value of the bit at the same position in the second bit stream or,
- (ii) obtaining two interlacing tables, each interlacing table being associated with a communication medium and arranging the data to be transmitted within the interlacing tables, and
- transmitting each data item to a MAC layer of the communication medium associated with a group to which said data item belongs.
