The 5G Solution Awarded by GTI for Innovative Breakthrough in Mobile Technology

Keysight’s S8800A PROPSIM F64 Channel Emulation Toolset is based on the first-to-market PROPSIM F64 5G channel emulator, which enables users to perform benchmarking of devices, base stations, digital radios, and sensor systems across the entire product workflow, from research and development to acceptance and field performance optimization. By performing a majority of the testing in a realistic lab environment, users can optimize time to market with improved maturity and reduce costs related to product development and maintenance.

Industry-leading mobile device, modem, and network equipment manufacturers use Keysight’s S8800A PROPSIM F64 Channel Emulation Toolset to integrate new 5G NR and 4G LTE product features and verify new hardware and software releases in a 24 / 7 automated test environment. Mobile network operators around the world use the S8800A toolset to validate 5G NR and LTE-A devices and base stations prior to product rollouts or software deployments in operational networks.

Keysight's PROPSIM F64 channel emulator supports a frequency range from 3 MHz up to 44 GHz as well as GCM-MANET and aerospace emulation tool options for aerospace and defense applications. These unique capabilities enable users to validate a wide range of RF and mmWave applications in the aerospace, avionics, satellite, and defense industries.

Key application areas include:

End-to-End Real-world Performance Testing in The Lab

PROPSIM F64 Channel Emulation Toolset

5G introduces new advanced technologies, including wider signal bandwidths, mmWave frequencies and massive MIMO with hybrid beamforming. To address associated complexities, Keysight was the first to market with a 5G NR channel emulation solution, supporting the widest signal bandwidth and highest number of fading channels.

The S8800A PROPSIM F64 Channel Emulation Toolset is designed for end-to-end realistic and repeatable real-world performance testing in the lab. The solution addresses all 5G NR key technical requirements, including:

  • Signal bandwidths up to 400MHz
  • Continuous carrier aggregation (CA) schemes up to 1.2GHz
  • Non-contiguous CA schemes up to 16CC
  • Massive MIMO using radio channel models defined in TR38.901 for both conducted and over-the-air (OTA) testing, across sub-6GHz and mmWave frequencies

The toolset supports a wide range of deployment scenarios:

  • 5G NR non-standalone (NSA) mode (using LTE as an anchor cell)
  • 5G NR standalone (SA) mode
  • Coexistence scenarios – 5G NR together with 3G and/or 2G cells
  • Wi-Fi offloading scenarios
  • 802.11ax capable access points and devices up 7.2GHz band

Extend Your Channel Emulation Toolset

By combining the S8800 PROPSIM F64 Channel Emulation Toolset with Keysight's E7770A Common Interface Unit and Keysight’s remote radio head (M1740A mmWave Transceiver for 5G), the solution extends to also address frequencies in 6-12GHz and mmWave 24/28/37/44GHz bands. Users can validate device and base station performance over-the-air (OTA) with multi OTA probe chambers designed for test cases across the device and base station workflow.

PROPSIM 5G RF fader platform seamlessly integrates with Keysight’s 5G Network Emulation Solution portfolio to coherently emulate complex fading test scenarios with protocol signaling for complete end-to-end device performance testing in sub 6GHz and mmWave bands.
