Partnering with IPNetfusion
We have worked in the network testing industry since 2003, first as a distributor and later as a developer of our own platforms. TDST, our flagship 5G Standalone test system, is already deployed by major Japanese telecom operators and network equipment vendors.
Until now, we have delivered TDST primarily within Japan. We are now opening it to international distributors and system integrators, and we are looking for a select group of early partners to help shape and drive our global partner program.
