Milestone Celebrated Using ETS-Lindgren’s RF Anechoic Chamber at VIAVI VALOR™ Lab

First Product Validated at the VALOR Lab’s RF Anechoic Chamber

CEDAR PARK, Texas, July 10, 2025 – ETS-Lindgren is pleased to announce VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has successfully completed end-to-end over-the-air (OTA) validation of Metanoia Communications Inc.’s JURA Open Radio Unit (O-RU) at the VIAVI Automated Lab-as-a-Service (VALOR™). It is the first product to be validated at the lab’s new ETS-Lindgren-designed and -installed RF-Shielded Anechoic Chamber. This validation ensures compliance with O-RAN and 3GPP specifications.

VALOR is an automated Lab-as-a-Service for Open RAN testing and is funded by the National Telecommunications and Information Administration (NTIA) Public Wireless Supply Chain Innovation Fund. The VALOR lab officially opened on October 7, 2024, in Chandler, Arizona, with the RF Chamber; two additional customer labs were added to the facility on April 3, 2025.

Metanoia’s O-RU underwent end-to-end performance validation to ensure seamless integration into Open RAN networks, with tests using reference O-CU and O-DU components provided by VALOR and its partners. Tests were conducted over the air within the RF Chamber, with VALOR evaluating key performance metrics under realistic radio conditions. Additionally, O-RAN end-to-end functional and performance validation was carried out based on O-RAN testing and integration focus group-defined test cases. Assessing the system's behavior across the control, user, and management planes, these tests ensured compliance with key O-RAN architectural and performance requirements in an integrated multi-vendor DU/RU setup.

“Congratulations to VIAVI on its success with having the first product validated at the lab’s new RF-Shielded Anechoic Chamber to ensure compliance with O-RAN and 3GPP specifications,” said Andy Warner, President with ETS-Lindgren. “We are proud to support their team with this innovative, customized Chamber to bring the next generation of OTA base station test methodology to the industry.”

“The successful validation of Metanoia’s O-RU using the new ETS-Lindgren Anechoic Chamber is an important milestone for VIAVI and the VALOR lab,” said Erik Probstfield, Senior Director, VALOR, VIAVI. “Open RAN-based systems are set to significantly increase telecoms innovation, but a network is far too complex an environment to rely on trust alone. VALOR, especially with its OTA testing, allows companies such as Metanoia to independently validate the functionality and performance of their hardware, and gives network operators assurance that it will integrate seamlessly into their existing networks.”

The VALOR RF Chamber is the industry’s first Test-as-a-Service offering Massive MIMO and beamforming OTA validation. It creates a controlled environment that is free from outside interference and emulates multiple real-world scenarios by sending wireless signals to understand a device’s behavior. Created in partnership with ETS-Lindgren, services offered include system-level Massive MIMO performance testing for up to 16 parallel spatial layers.
