Architecture
There are many similarities between existing RFoWR systems and RoE topologies. The terminology is different but there is essentially a one-to-one correspondence between RFoWR master nodes <-> RoE Mappers and RFoWR slave nodes <-> RoE deMappers.
It is anticipated that multiple Mappers (or master nodes) may wish to be deployed on the same Ethernet network, facilitating the multiplexing of RF signals.
Proposal
In November 2019, a proposal was made to the IEEE1914.3 working group to incorporate RFoWR as an Informative Annex. This proposal illustrates the use of organizationally unique identifiers to create a subType mapping called, structure-aware DDS mapping.
