Nokia said the testing was carried out at its O-RAN Innovation Center in Dallas

Finnish vendor Nokia announced that it has successfully completed interoperability testing with a Mavenir radio using the O-RAN Alliance 7-2x interface at Nokia’s Open RAN Innovation Center in Dallas, Texas.

During the trial, Nokia and Mavenir validated the interoperability of Mavenir’s CBRS radio unit and Nokia AirScale Baseband supporting the O-RAN compliant 7.2x interface. The testing was performed according to O-RAN Alliance specifications, demonstrating end-to-end configurations with 5G user devices.

Also, Nokia and Mavenir noted they were able to demonstrate 5G peak performance by activating 4CC Carrier Aggregation using TDD and FDD spectrum in a 5G Standalone (5G SA) configuration.

Nokia said its anyRAN approach is designed to give mobile operators and enterprises more flexibility in building networks that combine purpose-built, hybrid and Cloud RAN architectures with common software. Nokia is supporting Open Fronthaul features on top of its RAN software which ensures mobile operators have performance parity with their existing RAN, the vendor added.

Nokia and Mavenir claimed to have invested heavily to advance the goals of the O-RAN Alliance to build open, interoperable and intelligent networks.

John Baker, SVP of business development at Mavenir, said: “This solution demonstrates a full circle of O-RAN interoperability whereby our industry-leading RAN portfolio integrates and interoperates in both directions with products from other RAN suppliers. This is real Open RAN – not the version where one supplier only connects their own products to each other.”

“Our technology collaboration with Mavenir is further evidence of our commitment to Open RAN. We have developed our baseband software in a way that ensures that multi-supplier O-RAN systems can be deployed without compromises in performance, energy efficiency, security, or resiliency. This is key when people depend on wireless connectivity in all aspects of their daily lives. We have now completed operability with radios from four different suppliers using the O-RAN compliant 7.2x interface,” said Mark Atkinson, head of RAN at Nokia.

In February, Nokia had announced the launch of its anyRAN approach to help mobile operators and enterprises choose purpose-built, hybrid or Cloud RAN solutions regardless of business model.

With the Nokia anyRAN approach, the software can run on any partner’s cloud and server infrastructure in addition to Nokia AirScale base stations and Nokia AirFrame servers, the vendor said.
