5G/4G O-RU Reference Platform

Overview

Comcores, Analog Devices, Intel, Radisys, and Whizz have partnered up to provide an O-RAN compliant O-RU Reference Platform (hardware and software) for pico/micro coverage to enable operators, radio vendors and contract manufacturers going to market quickly with a flexible and customizable radio solution.

Comcores supplies the full O-RU IP including software APIs, drivers and a local control interface. Comcores O-RAN RU IP has been integrated with Intel® JESD204B, IEEE1588, Ethernet IP components as well as other IP blocks to form a complete 4×4 radio sub-system that is able to process data end-to-end from ethernet port to RF transceiver.

The deliverables include a binary and/or Quartus project database, software framework to control and manage the platform locally, a complete verification suite in simulation and hardware along with the documentation package. The O-RU IP targets the Intel® Arria® 10 FPGA SoC.

Comcores O-RAN RU IP is a proven implementation of the O-RAN standard, allowing easy reconfiguration of the functionality for various applications while still keeping an ultra-small footprint. For more information on the O-RAN RU IP see O-RAN RU IP.
