Solving the physical synchronization challenges that keep distributed antennas from behaving as one coherent phased array.
Independent local oscillators drift apart over time, producing destructive phase interference at the combining point. ISACFabric transmits continuous over-the-air pilot tones so every distributed antenna locks onto a shared phase reference.
Real-time Kalman estimators recompute the phase drift matrix at 1 kHz, keeping constructive interference aligned at each target focal point as antennas and reflectors move.
Across a 20,000 square meter smart-factory testbed with 32 distributed access points, coherent beamforming lifted data rates by 380 percent while localizing AGVs to within plus or minus 1.2 centimeters.
