TM500 Cloud

Cloud-deployed O-RAN Tester

Validate O-RAN components deployed in the cloud

Ensure O-RAN network components work consistently and stay reliable when hosted in the cloud.

As the industry moves toward greater use of data centres, virtualization, cloud architectures and open architectures, testing requirements are expanded  – calling for effective versatile test tools that can work in a cloud environment. The cloud provides a means to deploy O-RAN components cost-effectively but does carry some challenges.

The TM500 Cloud is a cloud deployed O-RAN development and test tool. It has been developed to help Network Equipment Manufacturers, Service Providers and Hyperscalers ensure that cloud-hosted O-RAN network components can meet their performance and quality expectations based on those from traditional RAN deployments. Once those expectations have been met, TM500 Cloud helps to make sure they remain consistent and reliable when the network is loaded with variable traffic and changing conditions.

Use TM500 Cloud to ensure your Cloud deployments meet the QoS metrics required to meet stringent SLAs

Product Overview

  • TM500 Cloud is a software-only containerised UE emulator running on any standard COTS servers which meets resource requirements.
  • TM500 Cloud runs in private, hybrid, public cloud & in our customers orchestration environment.


  • Cost effectively accelerates early development.
  • Reduced TCO due to solutions ability to scale up and down depending on the requirements of the system under test, maximize ROI for every K/Mbit/s.

Use Case Example

  • Test O-DU and O-CU Components in the cloud, with and without a real core network.
