PlugFest in North America hosted by CableLabs at the Kyrio OTIC Lab focused on:

  • Multi-vendor O-RAN end-to-end system under test, based on the O-RAN E2E test specification, demonstrating cell capacity for signaling and user-plane traffic load. Moreover, the Fronthaul delay impact on user peak throughput was measured using Fronthaul impairment emulators.
  • Demonstration of O-CU interoperability, based on the O-RAN IOT test specifications, verified traffic scenarios across emulated F1 and Xn interfaces, as well as the open F1 and Xn protocol implementation. In addition, the O-CU demonstrated successful interoperability for F1AP and XnAP global, elementary, and mobility procedures.
  • Near-RT RIC testing for conformance to the O-RAN E2 interface specification (E2AP, E2 SM, E2 SM RC, and E2 SM KPM procedures) were verified following the E2 test specification. Moreover, a QoS xApp was integrated and tested.

In addition to the hosts, participants included Calnex Solutions, Capgemini Engineering, Lumentum Holdings, Radisys Networks, Sunwave Communications, VIAVI Solutions and Xena Networks.

PocFest in North America hosted by UNH-IOL, hosted by AT&T and DISH, took place in four labs:

  • University of New Hampshire InterOperability Lab
  • TIP Community Lab at Meta, Menlo Park CA
  • POWDER Lab and NSF PAWR SITE with the University of Utah
  • COSMOS Lab and NSF PAWR SITE with the Rutgers University, Columbia University, NYU Wireless

Activities focused on testing of conformance and performance of O-RU devices, measurements of energy saving and efficiency, integration of AI/ML for resource pooling and slicing, testing of RIC, xApps, SMO, and end-to-end interoperability testing.

In addition to the hosts, participants included AMD, Anritsu, Calnex, DZS, Fujitsu, HCL, Intel, Keysight Technologies, NEC, Radisys, Rohde & Schwarz, VIAVI Solutions, VVDN, VMware, Vodafone, Wind River and Xena.

Viavi builds up its Open RAN test suite

Viavi Solutions announced extensions to its Open RAN test suite, including:

  • RIC Test. TeraVM RIC Test validates the performance of the RAN Intelligent Controller (RIC) when presented with a wide range of RAN scenarios, tests the functionality of rApps and xApps, and provides the means to generate the data needed to train AI models.
  • Test in the Cloud. VIAVI allows any node – O-RU, O-DU, O-CU, RIC and Core – and complete end-to-end testing to be performed in public, private and edge cloud environments.
  • Test as a Service. VIAVI now provides a Test as a Service (TaaS), offering the support to maximize your engineering productivity and provide access to the right tools and expertise to enable the rapid delivery of high performance and ultra-reliable cellular communications products.
  • TMLite. The capabilities of the flagship TM500 Network Tester are now available in a streamlined version on a commercial-off-the-shelf (COTS) server, enabling vendors to deploy focused functional test tools earlier in the development cycle, and allow smaller vendors to gain access to the TM500 family with a more compact package. The TMLite is built around the latest third-generation AMD EPYC processors which offer high compute and input/output flexibility per server, enabling multiple carriers of 4G and 5G at RF and Open Fronthaul.

VIAVI also highlighted the following partnerships:

  • Capgemini. VIAVI has collaborated with Capgemini, through Capgemini Engineering in Portugal, to deliver an industry-leading 5G and O-RAN lab test capability, powered by VIAVI's O-RAN Lab as a Service (LaaS) to ensure successful network integration of 5G networks and accelerate Lab-to-Live trials for Open RAN.
  • Ericsson. VIAVI will be delivering geolocation capabilities as a Non Real-time RIC Application (rApp) on the Ericsson Intelligent Automation Platform, a service management and orchestration product which enables any mobile network, purpose-built or Cloud RAN / Open RAN, to be intelligently automated.
  • Rohde & Schwarz. VIAVI and Rohde & Schwarz are partnering to offer an integrated solution for conformance testing of O-RAN Radio Units (O-RUs), including the O-RU Test Manager which provides a seamless user experience.

"Open RAN is moving out of the lab into the real world, facing the messy complexities of mapping theoretically sound technologies and architectures to a wide diversity of implementation scenarios," said Sameh Yamany, Chief Technology Officer, VIAVI. "VIAVI has harnessed its decades of leadership in test tools for cellular and virtual networks, our critical role in industry organizations such as the O-RAN ALLIANCE, and our relationships with other major vendors to ensure our customers have access to tailored and best-of-breed solutions."
