Radisys Series — Who Disaggregated My RAN?
eBook
This standardized fronthaul interface is a big step for the industry in ensuring interoperability and multivendor DU
and RU solutions in deployment.
O-RU Products Enabled by O-RAN Fronthaul
The O-RAN Alliance standard for fronthaul has enabled new players in the RU market and provided operators
with more innovative choices and cost optimized radios. For example, TIP announced the Evenstar program which
enables OEMs and operators to bring down the cost of RAN deployments. Recently, Radisys partnered with Intel,
Analog Devices (ADI) and Comcores to deliver an open reference design for O-RU. We published a whitepaper,
Delivering an Open Radio Unit for Outdoor Macro Cell Deployments, on this design. This reference design is also
available as a working demo for 5G DU and RU connected end to end. We are sure that this reference design is
going to enable deployable RUs at affordable cost.
It is not an exaggeration to say the open fronthaul and O-RU are the epicenter of the Open RAN revolution. The last
mile is promoting openness and is attracting operators concerned by the need for standards which drive greater
interoperability while reducing the bandwidth demands needed for low-latency applications.
