Keysight Technologies, Inc. has introduced a suite of end-to-end solutions that enables an ecosystem of Open Radio Access Network (O-RAN) vendors and mobile operators to verify interoperability, performance, conformance and security of multi-vendor 5G networks based on O-RAN standard interfaces.
Many mobile operators are deploying cloud-native and virtualized RAN architectures based on specifications set by the O-RAN Alliance to deliver 5G services. The transition towards multi-vendor networks introduces interoperability and performance complexity. End-to-end testing, from the edge of the RAN to the 5G core (5GC), as well as from early pre-silicon development to system integration, ensures performance levels are met. Comprehensive testing across a heterogeneous network enables vendors to extend the capabilities of their designs and mobile operators to deliver solutions that support innovative service offerings.
"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," said Giampaolo Tardioli, vice president and general manager for Keysight's network access group. "Keysight's end-to-end open RAN solution portfolio enables this ecosystem to verify components across every level of the protocol stack, ensuring that subsystems perform as expected and cohesively."
Keysight's Open RAN Architect (KORA) offers integrated solutions that accelerate the development, integration and deployment of O-RAN-compliant equipment. The suite is tailored to the supply chain workflow consisting of chipset makers, network equipment manufacturers (NEMs), mobile operators and Open Test and Integration Centers (OTIC). Users can uniquely access a common set of solutions to simplify the sharing of results across the workflow from pre-silicon to cloud deployments.
Keysight joined the O-RAN Alliance shortly after its inception. Early engagement with key industry stakeholders has resulted in broad and deep expertise in the O-RAN standards. As editor of the O-RAN fronthaul conformance test specifications in the O-RAN Alliance, Keysight's continuous contributions to the development of the O-RAN standards is enabling the industry to verify compliance of O-RUs and O-DUs to O-RAN specifications using approved O-RAN test cases. As the liaison of the O-RAN Alliance Security Task Group, Keysight is helping to drive industry efforts that address security in open RANs.
KORA includes Open RAN Studio, UeSIM, RuSIM, CoreSIM, DuSIM, CuSIM, RIC Test, ATI Pentest, CyPerf, Breaking Point, Vision Edge, IxNetwork, CloudPeak and Nemo Outdoor.
The portfolio covers both 3GPP and O-RAN testing and is segmented to support the following key stakeholders:
• KORA – Chip Designer Suite
Enables chipset vendors to verify compliance of O-RAN designs to O-RAN specifications using O-RAN simulation tools prior to tape out, reducing development time.
• KORA – NEM Suite
Enables open RAN hardware and software vendors to verify compliance to O-RAN specifications and interoperability, ensuring each function integrates as expected into a multi-vendor open RAN.
• KORA – Operator Suite
Enables mobile operators to verify conformance, interoperability and performance of subsystems that drive new 5G service revenue opportunities.
• KORA – OTIC Suite
Enables OTICs to validate conformance, interoperability and performance using tools that adhere to the O-RAN specifications with thorough, repeatable and automated processes.
