Anritsu and Spirent Communications Collaborate to Provide Open RAN Test Solutions


Anritsu Corporation (President Hirokazu Hamada) has announced a strategic partnership with Spirent Communications in Open RAN*1 test solutions. This collaboration will play a key role in helping equipment vendors, carriers, system integrators, cloud service providers, and others to configure an Open RAN ecosystem by measuring wireless RAN O-RU*2 characteristics, fronthaul Conformance Tests and End-to-End tests connecting O-DU*3, O-CU*4, and Core.

The Open RAN is the concept specifying open standards for network interfaces to expand services and reduce costs by supporting multivendor equipment sourcing as well as to enable intelligence, helping drive growth and creating new business opportunities. Mobile network operators and equipment vendors are testing and introducing Open RAN led by the O-RAN*5 ALLIANCE and other promotion groups.
