Plain-language CSI: reading human movement from Wi-Fi
Every Wi-Fi packet carries rich multipath data. Vantage captures those channel variations, denoises them, and feeds them into pose inference models—creating a live skeletal overlay without ever illuminating the target.
Passive capture
We only listen. Commodity radios observe the environment’s response to existing Wi-Fi, keeping teams dark.
Pose-first pipeline
All feature extraction—from motion vectors to behavior scoring—supports the skeletal pose estimator.
Why passive matters
- ▹ No new emissions means no EM signature to detect or jam.
- ▹ Operates under EMCON policies and inside RF-denied structures.
- ▹ Works where cameras fail—smoke, darkness, or obscured LoS.
Sensor Comparison
| Attribute | Cameras | Radar | Vantage |
|---|---|---|---|
| Line of Sight | Requires clear LoS. | Limited through-wall performance. | Sees through walls using ambient Wi-Fi. |
| Emissions | Visible-light signature. | Active RF emissions. | Zero-emission passive capture. |
| Detectability | Easily spotted or blinded. | Detectable with RF sweeps. | Covert; matches local Wi-Fi noise floor. |
| SWaP-C | Varies; often high power draw. | Bulky arrays and high power use. | Runs on Pi/Jetson-class compute under 25 W. |
| Cost | High for rugged PTZ systems. | High procurement and sustainment. | COTS radios with software-defined capability. |
Roadmap
MVP
Single-node CSI capture with live pose skeleton overlay and mission logging.
Multi-node Mesh
Cooperative nodes fuse CSI for volumetric pose tracking and coverage resiliency.
ATAK Plugin
Live overlays pushed to ATAK with pose states, alerts, and mission playback.
Platform Integrations
APIs for C2 suites, digital twins, and robotic controllers with pose metadata.
Security & Ethics
Vantage never records video or audio. All processing stays local, logs are redacted for PII, and exports are encrypted. Passive sensing respects privacy while giving teams the pose intelligence needed to reduce collateral risk.
- ▹ Signed firmware, secure boot, and tamper logging for field hardware.
- ▹ Role-based access for dashboards and CLI tooling.
- ▹ Export controls built-in for coalition sharing agreements.
