See Into the Electromagnetic WorldDeterministic Ray Tracing Simulation Engine
Grounded in the first principles of physics, Lauraycs precisely reproduces the reflection, diffraction, and penetration of electromagnetic waves in real three-dimensional environments. It turns invisible electromagnetic signals into engineering objects that can be known, measured, and predicted, delivering high-fidelity channel and coverage data for next-generation R&D in communication, sensing, and positioning.
Challenges of Our Era
Why Is Wireless Prediction Still So Hard?
From autonomous driving to smart factories, from the low-altitude economy to 6G, wireless connectivity has become critical infrastructure. Yet the complexity of the physical world causes traditional prediction methods that rely on statistical models to fail comprehensively in fidelity, repeatability, and coverage of extreme scenarios.
Dynamic Complexity of Scenarios
Moving vehicles, robots, and crowds alter signal propagation paths in real time; traditional static, statistical models cannot capture time-varying multipath and Doppler.
Uniqueness of Environments
Every factory, every street, and every low-altitude corridor in flight is one of a kind, and "average" statistical models cannot reflect the performance bottlenecks of a specific scenario.
Limits of Physical Testing
Real-world drive tests / field tests are costly, time-consuming, and non-reproducible, and have become a serious bottleneck for product R&D and network deployment.
Our Approach
Building a Digital Twin of Electromagnetic Space with Deterministic Ray Tracing
Rather than relying on "guesswork," we take physics as the first principle to precisely reproduce every reflection, diffraction, and penetration of electromagnetic waves in real three-dimensional environments, mapping the physical world 1:1 into digital space. Lauraycs provides end-to-end capability from 3D scene input and channel generation to engineering-ready output.
Deterministic Prediction
Based on precise 3D scenes and physical laws, it outputs "what you see is what you get" multipath, coverage, and time-varying results, instead of vague statistical probabilities.
High-Fidelity Reproduction
It precisely computes the strength, delay, AoA/AoD/ZoA/ZoD, and Doppler of every multipath component, and can further converge errors through measurement-based calibration.
Infinitely Repeatable
Reproduce any hazardous / extreme scenario at zero cost in the digital world, accelerating product iteration, algorithm validation, and network planning.
