PROPSIM Channel Emulation 5G Massive MIMO Testing

Sub 6GHz Massive MIMO

Massive MIMO enable increased cell capacity for 5G and LTE

The right tool enables quick validation of network –device interoperability and performance for real-world operation.

With full Antenna Array Sampling Massive MIMO solution all antenna array ports are sampled simultaneously allowing realistic modelling of spatial separation between multiple Mobile Devices for multi-user MIMO 3D Beamform validation. Verify performance from 16x16bi to 64x16bi for complete base station MU-MIMO TM9 UE feedback and uplink SRS based massive MIMO scheduler/beamformer testing.

mmWave Interoperability & Performance

mmWaves provide lots of new spectrum for Mobile users. 5G NR mmWave deployments rely on full mobility support and 3D beamforming at base station and mobile device. RF propagation condition at mmWaves is lot more challenging vs. Sub-6GHz due to high blocking.

How to validate mmWave base station and mobile devices before deployments for real-world operation?
