The Extensible Radio Access Network (O-RAN WG4 Fronthaul Interface) defines a fronthaul interface between a lower-layer split distributed unit (DU) and remote unit (RU) in an Evolved Universal Terrestrial Access Network (E-UTRAN) and Next-Generation Radio Access Network (NG-RAN) system with a lower layer functional split-7-2x based architecture. The O-RAN IP implements control and user plane protocol specified in O-RAN-FH.CUS.0-v03.00.
O-RAN Intel® FPGA IP
Overview
Key Features
