On March 6, 2025, Keysight Technologies, Inc. (NYSE: KEYS) announced a strategic partnership with Mavenir aimed at enhancing the testing and validation of Mavenir’s innovative 32TRX massive multiple input multiple output (mMIMO) technology. This collaboration leverages Keysight’s advanced Beam MIMO Detect solution to facilitate efficient beamforming in next-generation Node B (gNB) systems, ensuring a robust and optimal user experience.

2. Enhancing User Experience Through Comprehensive Testing

The collaboration between Keysight and Mavenir focuses on the critical task of testing mobility and multi-user MIMO (MU-MIMO) for massive MIMO gNBs. This involves simulating real-world scenarios where multiple user equipment (UE) are spatially distributed and in motion, thus allowing the network to handle dynamic conditions while maintaining high performance levels.

One of the significant challenges in this realm is managing inter-beam interference, which can adversely affect the performance of MIMO systems if not modeled accurately. The complexity of beamforming, channel modeling, and interference management in multi-cell environments necessitates sophisticated testing setups that can replicate real-world conditions for validating the robustness of the network.

3. Keysight's Cutting-Edge Testing Solutions

Keysight’s Beam MIMO Detect and end-to-end (E2E) MU-MIMO solutions provide a compact benchtop setup featuring up to 64 bidirectional radio ports. This setup is crucial for simulating complex multi-user interference scenarios. Through this collaboration, Mavenir successfully tested its 32TRX mMIMO technology, which included assessments of inter-beam and inter-cell mobility, ensuring that Mavenir’s solutions are robust and optimized for delivering a superior user experience.
