Keysight's O-RAN tests posted on AWS Outposts

Keysight Technologies' open radio access network (O-RAN) test solutions are now available on AWS Outposts.

AWS Outposts is a fully managed service that offers the same AWS infrastructure, AWS services, APIs and tools to virtually any datacenter, co-location space, or on-premises facility for a consistent hybrid experience. Vendors of radio units (O-RUs), distributed units (O-DUs), central units (O-CUs) and RAN Intelligent Controller (RIC) need integrated, virtualized and cloud native solutions to validate performance, establish interoperability between network elements and ensure compliance to the latest O-RAN and 3GPP specifications.

Keysight’s open radio access network (RAN) architect (KORA) consists of multiple simulators working in unison to deliver a seamless solution to vendors, carriers and testers to verify the end-to-end O-RAN ecosystem infrastructure. 


The KORA suite that is now available via AWS Outposts brings together all the major elements for testing the evolving RAN ecosystem in one comprehensive family of test solutions, including RuSIM, DuSIM, CuSIM, RIC Test and LoadCore.

RuSIM provides fully scalable RU emulation on the fronthaul interface for O-DU functional, performance full-stack testing, protocol conformance testing and interoperability compliance testing. DuSIM validates open central unit (O-CU) performance in accordance with 3GPP standards and aligns with O-RAN C-plane and U-plane parameters of performance and interoperability with 5G and O-RAN network functions. Capable of generating hundreds of O-DU’s and thousands of UE’s, DuSIM provides optimal performance of the O-CU under heavy loaded conditions with realistic voice, video and data traffic. CuSIM helps infrastructure vendors, chipset providers and mobile operators validate the open distributed unit (O-DU) functionality by emulating traffic over the mid-haul interface.

In addition, RIC Test helps vendors and mobile operators validate RAN Intelligent Controllers (RIC) and RIC enabled artificial intelligence/machine learning xApps and rApps (intelligent applications hosted on the RIC platform that control resource allocation across the 5G networks) used to efficiently manage radio resources. This is a done by emulating traffic scenarios over distributed set of RAN elements (eNB, gNB, CU, DU) over the O-RAN Alliance’s E2 interface. LoadCore allows communication service providers (CSPs) to scale their network and edge capabilities beyond past on-premise presence, delivering flexible, rapid deployment and execution of their continuous integration (CI) and continuous delivery (CD) pipeline.

“Keysight is extremely pleased with the opportunity to offer our key 5G testing solutions on AWS,” said Kalyan Sundhar, vice president and general manager, 5G Edge to Core Solutions at Keysight. “Embracing the future of dis-aggregated 5G RAN open interfaces allows legacy providers and emerging stakeholders’ new opportunities to explore advancing technologies in multiple diverse vertical segments such as autonomous vehicles, remote medicine and connected cities, that private networks will allow to become reality.”

VMware and Cohere Technologies collaborate on O-RAN

Cohere Technologies and VMware are developing an O-RAN solution to help CSPs improve network and spectrum efficiencies and deliver new and differentiated services and experiences for their customers.

The solution will bring together:

  • VMware’s RAN Intelligent Controller (RIC) Platform
  • Cohere’s Spectrum Multiplier and Cloud Scheduler xApps
  • The RAN Intelligent Controller (RIC) is a new function introduced by the O-RAN Alliance that enables CSPs to deploy cloud-native control and management apps in the RAN. Essentially, it virtualizes the RAN Centralized Units (CUs) and Distributed Units (DUs), where complex RAN intelligence was previously embedded. VMware has designed its RIC platform keeping developer experience at the center and offers a RIC Software Developer Kit (SDK) to any third-party developer to build apps that can be deployed in the RAN. Today most of these apps are geared toward making the network faster, including Cohere’s Spectrum Multiplier xApp.

Cohere says its Spectrum Multiplier and Cloud Scheduler xApps improve spectral efficiency for CSPs by as much as 2x by enabling existing mobile networks to communicate with multiple users simultaneously on the same time and frequency resources. This is achieved by using dynamic and smart pairing as well as precoding techniques. 

“CSPs are spending tens of billions of dollars on 5G spectrum and being able to get the most out of that investment is critical,” said Ray Dolan, Chairman and CEO of Cohere Technologies. “Cohere is the first company to overcome the latency challenges of moving critical intelligence from the RAN to the cloud using VMware’s RIC Platform. Our software, when running on VMware’s RIC platform, provides CSPs with a powerful solution to extend spectral efficiency and deliver a great user experience to customers accessing 5G services.”

Vodafone tests multi-vendor RAN intelligent controller


Vodafone, in conjunction with Cohere Technologies, VMware, Capgemini Engineering, Intel and Telecom Infra Project (TIP), demonstrated an Open Radio Access Network (RAN) platform capable of increasing the capacity of a 5G cell site by two-fold using a programmable, Artificial Intelligence (AI)-based RAN Intelligent Controller (RIC).

Specifically, he companies showed the first demonstration of 5G Multi-User MIMO (MU-MIMO) – providing more capacity at a single cell site – running on a RIC located at a multi-vendor Open RAN test site.  MU-MIMO apportions ample bandwidth to individual users connected to the same mobile site and is considered the pivotal technique to boost cell capacity in future 5G networks. It is a major development in supporting the insatiable demand for faster and more responsive digital connections to deliver high definition graphics, virtual reality, cloud and IT applications.


Based on the performance of Cohere’s Spectrum Multiplier MU-MIMO scheduler in the trial, when the technique is commercially deployed in a low-band (e.g. 700MHz) network, users will benefit from up to 2x the capacity achieved using traditional MIMO. This software can be extended to Massive MIMO in mid-band (e.g. 3.5GHz) networks in order to push capacity gains towards 4-5x.
