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.
