Simplify Your mMIMO Testing

Massive MIMO (mMIMO) and MU-MIMO technologies expand 5G resource scheduling beyond just frequency and time, introducing spatial domain control for significantly improved network capacity and efficiency. As a result, thorough testing of MU-MIMO functionality is essential to validate the performance and reliability of any Radio Access Network (RAN). However, existing MU-MIMO test setups—typically relying on anechoic chambers or discrete phase shifters—are often complex, cumbersome, and difficult to scale.

The P8800S UeSIM - E2E Massive MIMO Testing Solution, equipped with the P88206A Beam MIMO Detect (BMD) RF front-end, delivers a groundbreaking alternative to the limited testing options currently available in the market. This compact benchtop size test system delivers powerful, scalable testing capabilities for multi-user MIMO (MU-MIMO) configurations. As the first to market solution UeSIM with BMD provides a fully integrated platform for comprehensive MU-MIMO and beamforming validation. It enables large-scale simulation of MU-MIMO scenarios with realistic field conditions, dynamic mobility, and automated calibration tailored to vendor-specific implementations.

Keysight’s P8800S UeSIM - E2E Massive MIMO Testing Solution emulates a spatially distributed and dynamically moving UEs. As a fully programmable solution it supports the Massive MIMO (mMIMO) testing requirements for current and future mobile communications industry standards.

The solution supports up to 64 independent bidirectional RF ports operating in FR1 TDD bands, accommodating a wide range of MU-MIMO configurations, creating a full-stack testing environment. Beam separation and composition are handled digitally, with the resulting digital streams routed from BMD to UeSIM, which emulates the behavior of multiple spatially co-scheduled User Equipment (UEs) at the same time and frequency.

The small footprint of the solution enables the DUT radio and BMD unit to be housed in a compact 24U half-rack unit. The entire simulation is orchestrated by UeSIM providing seamless integrated testing solutions.

This fully reprogrammable, end-to-end solution supports large-scale UE emulation and high-throughput testing, enabling dynamic mobility scenarios and the precise replication of complex real-world use cases.
