WiTwin Channel

Differentiable radio propagation simulator for RF Digital Twin workflows

Overview#

WiTwin Channel is a differentiable radio channel simulator. Given a physical scene — walls, rooms, antennas — it computes how radio signals propagate through the environment. Because the simulator is differentiable, you can run gradients back through the simulation and solve inverse problems: inferring scene properties from signal measurements.

What It Provides#

  • Three solvers: deterministic ray tracing, Monte Carlo sampling, and per-path tracing
  • Scene construction with geometry, materials, transmitters, and receivers
  • Coverage map (radiomap) computation over receiver grids
  • Per-path CIR and CFR extraction
  • Full differentiability for inverse design and optimization workflows
