Analyze RF System Performance in Accurate Virtual Twin Environments

With Ansys RF Channel Modeler, systems engineers employ a model based design approach to represent their systems within a physics accurate digital environment.  Designs can be explored and tested across simulated situations and conditions which would otherwise be difficult to replicate under real-world field-testing scenarios by following a streamlined modeling and simulation workflow:

  • Model The Operating Environment: From general underlying terrain and topography data to high resolution building models, RF Channel Modeler’s workflow starts by defining an accurate digital simulation environment.  With support for OGC 3DTiles standard RF Channel Modeler makes it easy to consume large geospatial data sets, ideal for highly detailed meshed 3D models such as urban cityscapes
  • Platform Models: Whether your RF systems are stationary base stations or user equipment installed on vehicles, aircraft, or other platforms, RF Channel Modeler provides a physics-based motion and orientation modeling engine to get things moving!  With the ability to create simple representative routes or import existing trajectory data, users can quickly put their models in motion.
  • RF System Models: It couldn’t be easier to create representative models of transmitter, receiver, or even radar systems necessary for your simulations.  Get started with in-built models of common designs or import existing complex antenna designs directly from Ansys HFSS and configure the desired channel spectrum analysis settings.  Single click load for complete HFSS phased array base stations simplifies the workflow and enables high fidelity antenna designs to be easily integrated into the simulated environment.
  • Analyze and Explore: The engine ingests the terrain, buildings, objects, and materials contained in the 3DTiles data as meshed triangle geometry facets and material properties and leverages advanced GPU capabilities for scalable simulation execution.  Analysts can explore the resulting data containing scattering parameter (s-parameter) antenna-to-antenna coupling data between all antennas considered in the modeled scenario over the specified analysis period.  This data is also available for external post-processing and scripting as needed, making this a flexible solution for large, extended simulation data exploration and analysis efforts. The quantity and quality of the output is suitable for training of any AI tools. Customers might employ and train a variety of AI tools.
