Keysight Technologies 5G Channel Sounding Reference Solution

Keysight Technologies has introduced the 5G Channel Sounding Reference Solution. The reference solution is designed for accelerating research of millimetre-wave 5G channel models and includes ultrabroadband and MIMO — key requirements to measure the millimetre-wave channel and validate air interface standards.

The reference solution combines metrology-grade hardware, software and expertise to allow users to quickly characterise the channel behaviour in frequency bands from 10–100 GHz and enable researchers to develop the necessary channel models for designing and validating air interface alternatives. Researchers can get absolute delay measurements with system-wide calibrations, precise timing and synchronisation.

Users will also save time and disk space by using the multichannel, real-time data processing and correlation of the channel impulse response data offered by the M9703A high-speed digitiser FPGAs. Engineers can use Keysight’s SystemVue system-level design and simulation software platform to calculate channel parameter estimations and perform link-level simulations and validation of 5G designs with the imported channel models.

The reference solution also enables: Tx/Rx up to 44 GHz with 1 GHz bandwidth for four or eight MIMO channels; capture of multiple phase-coherent channels for real-time CIR data processing in FPGAs; flexibility and scalability to add more channels and tests as 5G standards evolve; and customisation of waveforms, models for channel parameter extractions and system integration.
