Core Engineering Areas

• Hardware-in-the-Loop (HIL) Bench Architecture — Validating production OBU and RSU silicon against millions of virtual miles in automated laboratory test racks.
• Dynamic RF Channel & Multipath Emulation — Simulating high Doppler shifts and deep Rayleigh fading caused by urban buildings directly through direct coaxial RF lines.
• SUMO, CARLA & NS-3 Co-Simulation — Synchronizing vehicle dynamics, optical physics, and network packet simulation across deterministic microsecond clock ticks.
