An open exploration of what walls already know.

The question

What can the radio tell us that nothing else can?

802.11 OFDM already exposes 56 CSI subcarriers of complex amplitude and phase per channel. Bodies, motion, breathing, occupancy, even slow material changes leave fingerprints in that matrix. We don't need new hardware to see them — we need to read what the standard already exposes, and ask whether the result is good enough to replace cameras for the workloads where cameras are an expensive default.

There are three pieces:

• LatentField — the sensing core. The compression of 56 subcarriers into 8 latent fields and the inference pipeline that runs them.
• CameraPlus — the proof-of-concept deployment. RF first, camera on trigger. Numbers, verticals, honest boundaries.
• MonitorPlus — the managed service. What it looks like when someone else runs the system for you, across four deployment configurations.

The thesis

Two sentences, twenty-five years in the making.

AI agents should not only read documents; they should operate against executable, deterministic, auditable context — code, intents, tools, simulators, and rollback-safe workflows.

Cameras are an expensive default. WiFi CSI + selective vision + conversational interface is materially better in power, bandwidth, privacy, and resilience for a wide class of industrial monitoring workloads.

That's it. Every artifact on this site exists to make those two sentences testable.
