Spirent Communications has announced that NTT DOCOMO, INC. is using Spirent technology for its 5G open radio access network (O-RAN) ecosystem (OREC) testing. Utilising Spirent’s O-RAN capabilities, NTT DOCOMO is testing the O-RAN for multi-vendor interoperability and real-world performance to support the implementation of open RANs.

Commenting on the development, Doug Roberts, general manager, Spirent Lifecycle Service Assurance, said, “Customers like NTT DOCOMO have an excellent opportunity to leverage O-RAN to build a true multi-vendor network that drives increased innovation to deliver unique and differentiated services to their customers. However, due to the complexity involved, operators need to ensure that the O-RAN technology functions and performs as expected. Spirent technology provides that validation.”

Meanwhile, Sadayuki Abeta, corporate evangelist, NTT DOCOMO, said, “Because O-RAN is a disaggregated network, each O-RAN function needs to be tested independently, as well as with the adjacent functions together, and then end-to-end. “Emulation in particular is a critical element of any O-RAN testbed and Spirent is the market leader in this area. Including its technology as a key component of OREC testing will ensure operators can gain confidence in their O-RAN deployments.”

Spirent‘s solutions provide the most comprehensive library of 5G testing features and functions, while they can also scale in terms of users and performance. The combination of the portfolio focused on the O-RAN testing challenges provides the most complete, integrated solutions for addressing the O-RAN market specifically designed and tailored for functional and performance testing.

The OREC project leverages NTT DOCOMO ’s expertise and the capabilities of major global vendors. It provides open labs that enable mobile network operators to become familiar with the OREC ecosystem and test multivendor solutions. The OREC project promotes the interoperability and commercialisation of vRAN solutions conforming to the O-RAN Alliance standards.
