2.3 Radio over Ethernet (ROE) and common public radio interface (CPRI)

Bomin Li, Comcores
Presentation Fronthaul

This is a demo for both next generation fronthaul interface (NGFI) native radio over Ethernet (RoE)
with intra PHY split implemented in it, and CPRI over Ethernet encapsulated in the structure agnostic
mode. Compared to CPRI, the NGFI native RoE implementation significantly improves bandwidth
usage, which better supports 5G applications demanding higher bandwidth. More information is
provided here. In the CPRI over Ethernet demonstration, bidirectional CPRI flows are recovered
without error, which enables centralized radio access network (C-RAN) architecture by using
Ethernet as a transport network.
