Increased cell capacity for 5G and LTE

Massive MIMO provides increased cell capacity for 5G and LTE. Using the right tools enables quick validation of network-device interoperability and performance for real-worl operation.

With the full antenna array sampling massive MIMO solution, all antenna array ports are sampled simultaneously allowing realistic modeling of spatial separation between multiple mobile devices for multi-user MIMO 3D beamform validation. You can verify performance from 16x16bi to 64x16bi for complete base station MU-MIMO TM9 UE feedback and uplink SRS-based massive MIMO scheduler/beamformer testing.

Simplified partial antenna array sampling massive MIMO testing with an external RF analog combiner or phase shifter matrix is an optimized solution for cost effective multi-user, multi-RAT, and handover mobility focused UE and base station testing. It supports the antenna array column/row combination and virtual probe/key-hole-channel channel emulation configurations.

mmWave Interoperability and performance

mmWaves provide plenty of new spectrum for mobile users. 5G NR mmWave deployments rely on full mobility support and 3D beamforming at base stations and mobile devices. RF propagation conditions at mmWaves are significantly more challenging than at Sub-6GHz due to high blocking.
