Massive MIMO provides increased cell capacity for 5G and LTE. Using the right tools enables quick performance optimization and validation of network-device interoperability. Integration and optimization of O-RAN RU and DU elements for optimal operation are essential for multi-vendor network end-to-end performance.

With the advanced 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 multi-user MIMO TM9 UE feedback and uplink SRS-based massive MIMO scheduler/beamformer testing.

Massive MIMO testing with an external RF analog combiner 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.

The S8803A toolset makes comprehensive testing easy for the user by offering ready-made and verified test case packages and tools for custom test creation.

The S8803A toolset enables you to emulate up- and downlink massive MIMO channels in real-time and is extendable to:

  • Measure all downlink beams simultaneously with an integrated multi-port signal analyzer
  • Test all uplink beams with an integrated multi-port signal generator
  • Analyze and debug up- and downlink signaling with an integrated RF sniffer
  • Test key performance indicators, such as single- and multi-user data throughput in an instant
  • Support creating RF Field-to-Lab test cases

F9860A Channel Studio

Keysight’s F9860A Channel Studio is a state-of-the-art radio propagation channel modeling software for real-time testing and performance evaluation of devices, radio systems, and transceivers. It simplifies the creation of multi-link test scenarios for wireless testing and special radio systems testing. Channel Studio supports user-defined 3D spatial scenarios and dynamic modeling of movement for 5G testing:

  • 3GPP 38.901 CDL FR1 and FR2 models
  • UMi, UMa, O2I and I2O
  • SCME

The F9860A Channel Studio supports importing 3D antenna models. It offers 3GPP-defined channel models to test V2X safety applications as well as for on board Wi-Fi and cellular connection. In addition, device-to-device topologies are supported. The F9860A Channel Studio provides an interface to import data, which allows advanced users to bring test scenarios from external simulation tools.
