Viavi Solutions: TMLite network tester

Viavi Solutions Inc. recently released TMLite, a streamlined version of its flagship TM500 Network Tester, which is a scalable test system for validating network performance. The new version delivers features, software environment, and user experience consistent with the TM500 on a commercial off-the-shelf (COTS) server for early functional network testing. This enables users to deploy focused functional test tools earlier in the development cycle and allows smaller vendors to gain access to the TM500 family in a compact package, said the company.

To maximize 5G coverage, service providers will need to densify their networks, increasing the diversity of radio types and suppliers, said Viavi. “Smaller-scale manufacturers may not require the large number of carriers and high-capacity testing typical in traditional base station validation, but they still need early access to 3GPP features, as well as network parameters used by other manufacturers to confirm interoperability.”

TMLite enables functional, system, and performance testing for the latest 5G SA features, including FR1, FR2, FDD, TDD, and up to 4 × 4 MIMO, and it delivers the RF, baseband, and higher-layer processing for one 5G NR carrier — on a single COTS server. With TM500 family application programming interfaces optimized for automation environments, TMLite tests can be compared with TM500 insights for efficient parallel testing and product development.

In addition to the original network tester and TMLite, the TM500 family includes an O-RU Tester and an O-DU Tester.
