RE: Radio over Ethernet draft PAR for the IEEE 1904 pre-review & discussion
Jouni,
Perhaps I am trying to indeed engineer a solution within PAR.
If everybody else is fine with this level of detail, so will I

Marek,
Right. My assumption is that these details would go into PAR step 5.2. How
much more detail would be needed? Currently the scope says:
1) Standard specifies the encapsulation of digitized radio In-phase
Quadrature (IQ) payload and related control data into an Ethernet packet
including the necessary encapsulation within the encapsulating Ethernet
frame.
2) Both structure-aware and structure-agnostic encapsulation of existing
digitized radio transport formats are within the scope. The
structure-agnostic encapsulation is not restricted to CPRI.
3) The standard will specify a structure-aware mapper for Common Public
Radio Interface (CPRI) frames and payloads to/from Ethernet encapsulated
packets.
I am more than happy to clarify all above three steps. However, I would be
reluctant to go into detail that would allow a single solution outcome at
this point, since we do not know the details yet that everybody can agree
on.
- Jouni
