Solving 5G challenges:
One major change in 5G is the New Radio (NR). It will use much higher radio frequencies to achieve
higher
bandwidth required for the huge increase in connected devices and new use cases. Since higher
frequencies
will have shorter transmission range, more base stations will be required to cover existing areas. On
top
of
this challenge, suppliers for Radio Area Network (RAN) equipment have been limited to a handful of large
internation-al companies with proprietary solutions. Mobile network evolution has been slow while many
innovations have happened with Internet and Cloud software.
Service providers are migrating to open architecture-based RAN solutions for the transition to the 5G
era.
An open, cloud-native RAN concept has quickly gathered lots of interest and top global operators have
formed
the O-RAN alliance. O-RAN’s mission is to build a new 5G RAN on a foundation of virtualized network
elements, white-box hardware, and standard-ized interfaces that fully embrace O-RAN’s core principles of
intelligence and openness. As a contributing member of O-RAN, Supermicro is fully committed to
contribute
and deliver this solution with high performance Open RAN supported hardware which aim for disaggregate RAN functions.upermicro’s commercial off-the-shelf (COTS
Altiostar is a software vendor that provides 5G-ready virtualized RAN solutions supporting open
interfaces
and a disaggregated hardware/software solution to build a multi-vendor web-scale network. Altiostar’s
OpenRAN software suite with open interfaces provides a high degree of programmability and automation.
The
combination of Altiostar’s open software platform and Supermicro’s commercial off-the-shelf (COTS) edge
servers strengthened the wireless network operations, provides a reliable, flexible, scalable, and cost-compatible solution to realize the new RAN.

Reduce latency and improve the process
Overcome Challenges with 5G
Specifically, for the Distributed Unit (DU), the combined solution can support LTE or 5G with baseband
functions decoupled from the hardware and deployed on network functions virtualization (NFV)
infrastructure.
RAN cloudification is one of the fundamental tenets of the O-RAN architecture. The operators’ NFV and
virtual
infrastructure manager (VIM) requirements enhance virtualization platforms in support of various
functional
splits from 3GPP.
DU reference design for O-RAN White Box
The RAN DU sits between the Remote Radio Unit (RRU) and the Central Unit (CU) and includes real-time L2
functions, baseband processing, and radio frequency processing. Currently, Supermicro’s Xeon D-based
1019D-FHN13TP server is being proposed in a draft configuration for the DU in O-RAN’s white box working
group.
In this configuration, the DU will support 3 sectors of RRUs via a RIM card from Altiostar. The RIM card
will
provide CPRI-to-eCPRI conversion so that the baseband and radio frequency information can be transmitted
over
the IP network.
In above figure, the DU will support 12 sectors of RRUs with multiple LTE bands, requiring a large amount
of
digital signal processing in real time to perform the CPRI-to-eCPRI conversion. This task can be offloaded
to
an FPGA card, specifically the Intel FPGA Programmable Acceleration Card N3000. This card accelerates
network
traffic up to 100Gbps to support low latency and high bandwidth tasks such as FEC acceleration at the PHY
layer.
Supermicro and Altiostar are working together to provide a cloud-native total solution for DU based on
open
architecture, open APIs, and open-hardware servers, benefiting from cloud computing innovations such as
SDN,
virtualization, and containerization. The benefits of FPGA plus x86 CPUs are exceeding early expectations
on
improving the LTE/5G workload using virtualized infrastructure. This scalable design will allow operators
to
have the flexibility to design their network, enable software-only remote upgrades to following
generations,
and make continuous implementation and deployment a reality.
