Marvell’s O-RAN Solutions Overview

by · Published · Updated

There one more name to the OEM vendors for O-RAN products and name is Marvell Semiconductors. They announced their 5G O-RAN portfolio with a vRAN platform. Open RAN architectures enable multiple options for RAN components supplier and allows operators to choose, increase the flexibility, reduce the Copex. Open RAN is maturing days by days and now implementations have moved beyond lab trials and greenfield deployments to mainstream mobile and private networks.

Marvell O-RAN Platform Highlights

  • Its O-RAN solution consists of silicon (chip),  software and hardware reference designs inclding the radio unit (RU), distributed unit (DU) and centralized unit (CU) with Ethernet connectivity between these network elements
  • The O-RAN solution is Open Ran Alliance compliance and it will brings established, leading-edge DPU and connectivity technology to the emerging open RAN and vRAN
  • Solution will be based on OCTEON Fusion baseband processors and OCTEON multi-core DPUs
  • The OCTEON Fusion baseband processor has 15 Gbps capacity and support for 200MHz channelization,
  • It will be supporting O-RAN functions such as eCPRI compression/decompression and split 7.2 interfaces with integrated fronthaul
  • The platform includes key reference software, allowing OEMs, ODMs and network operators to rapidly bring O-RAN compatible products to market.
  • The platform development kits will be available in Q1 2021
