Description / Abstract:
This document defines the encapsulation and mapping of radio protocols for transport over Ethernet frames, using Radio over Ethernet (RoE). Structure-agnostic definitions are provided for any digitized radio data. Structure-aware definitions are provided for the Common Public Radio Interface (CPRI1,2). Native mode definitions are provided for digitized radio In-phase Quadrature (I/Q) payload and control data channels.
Purpose
This standard enables the transfer of In-phase Quadrature (IQ) user-plane data, vendor specific data, and control and management information channels across an Ethernet-based packet-switched network. The standard fosters interoperability among implementations by defining the framing, the encapsulation of the information, and a common Ethernet Type for Radio over Ethernet (RoE) purposes.
