5G user experience depends heavily on the wireless device's performance, but networks are also complex. Testing wireless devices in clean channel conditions is not enough to ensure that devices will operate as expected in real environments. Channel emulation helps assess real-world wireless connectivity performance on real devices and networks to ensure a positive customer experience.

The first-to-market PROPSIM Channel Emulators offer the widest signal bandwidth and the highest number of fading channels in the industry, enabling you to address the complexities associated with the introduction of new wireless technologies for 6G, 5G, Wi-Fi, satellites, aerospace, and defense communication systems:

  • Range pathloss and blocking effects emulation
  • Doppler mobility and multipath effects emulation
  • Noise and synchronous programmable signal generation playback
  • Embedded time and phase coherent multiport signal recording and signal analysis

Versatile and easy-to-use channel modeling and emulation tools enable users to simulate and test instantly across a wide range of wireless technologies on devices and networks, including:

  • 5G and 5G Advanced use cases
  • Prototyping 6G technologies
  • Massive MIMO, Extreme MIMO, Giga-MIMO
  • Non-Terrestrial Networks, NTN (3GPP and non-3GPP)
  • Integrated Sensing and Communications, ISAC
  • Wi-Fi 7 (802.11be) use cases 
  • Prototyping Wi-Fi 8 (802.11bn) technologies
  • Ultra-wideband and Bluetooth LE use cases
  • RF channel emulation from HF to mmWave frequencies

PROPSIM solutions are extensively utilized in 24/7 fully automated test environments to validate and verify performance and stability of new software releases on devices or radio networks prior to field deployment.

Testing 6G FR3 Systems with Advanced Channel Emulation

6G frequency range three (FR3) system test requires phase and time-coherent multichannel emulation using semi-deterministic and deterministic channel models. Key performance metrics for 6G FR3 testing include beamforming gain, beam width, and sidelobe levels from the physical layer (PHY) to the application layer.

Use a channel emulator and channel emulation software to perform 6G FR3 testing with geometry-based stochastic channel modeling and semi-deterministic and deterministic site-specific channel modeling. With a robust channel emulation solution, you can reproduce a diverse propagation environment as well as emulate hardware impairments like phase noise and interference.
