Alpine · WiFi Sensing A module of Ithildin Alpine

Sensing without cameras.

Presence, motion and occupancy read from the ordinary WiFi already present in a space. No lens. No image. No per-person identity. WiFi Sensing extends Ithildin Alpine — tactical edge vision and sensor fusion — into rooms where a camera is the wrong instrument, legally or operationally.

01 · How it works

The radio already in the room

Presence · motion · occupancy
read from the WiFi
already in the room

A moving body changes the WiFi already around it. The ordinary WiFi radios in a space are quietly sensitive to movement through them. When a person moves, Ithildin's analytics read that change and turn it into a simple, explainable signal — with no camera anywhere in the room.

The output is a coarse, physical estimate — not a picture. It becomes stable, explainable events: someone is here, something is moving, a zone is occupied, a broad class of activity is underway.

What it reads
  • Presence — is a space occupied or empty
  • Motion — is something moving, and roughly where
  • Occupancy — how many distinct zones are active
  • Coarse activity — broad movement state (still / walking / disturbance)
What it does NOT do
  • No pose or skeleton reconstruction
  • No vital-signs or biometric inference
  • No identification of specific individuals
  • No imaging — there is no picture to recover
02 · The hardware truth

The signal exists only in the room

An on-site radio, always —
no browser-only,
no cloud-only sensing

WiFi sensing cannot run from a browser or the cloud alone. This kind of sensing only exists where a radio physically sits in the space being sensed. There is no remote shortcut — if no instrumented radio is in the room, there is nothing to read.

So the customer owns and installs a small on-site capture appliance. Detection runs locally on that appliance. Only aggregate events leave the device — never the raw signal, never a reconstructable one. Ithildin supplies the AI and analytics layer plus the dashboard that turns those events into an operational picture. The hardware stays with the customer; the intelligence is ours.

03 · Why it's real

The category is proven

Research · standards
commercial deployment
at national scale

WiFi sensing is not speculative. It is an established research field, a published IEEE standard, and a product category already shipping in millions of homes. The references below are the industry's — not Ithildin's claims. What we add is the lawful, sovereign, Swiss-deployed analytics layer on top.

DensePose From WiFi

Carnegie Mellon University research demonstrating that human movement can be inferred from commodity WiFi signals — the academic anchor for WiFi-based sensing.

Research · CMU · arXiv:2301.00250
IEEE 802.11bf "WLAN Sensing"

A published 2025 IEEE standard that formally defines sensing as a first-class function of WiFi hardware — the category now has a standards body behind it.

Cognitive Systems · WiFi Motion

Motion sensing over existing WiFi, shipped through Comcast / Xfinity and 160+ internet service providers — commercial proof at consumer scale.

Commercial · 160+ ISPs
Origin AI

A WiFi-sensing company acquired by home-security provider ADT in 2026 — the security industry validating the technology through acquisition.

04 · Lawful by design

Customer-owned. Aggregate-only.

FADP
ArGV3 Art. 26
DPIA · balancing test

The customer owns the sensors and the legal basis. Ithildin does not operate a sensing network on anyone's behalf and does not sense any space the customer does not lawfully control. Every deployment is geofenced to customer-controlled boundaries and emits aggregate data only — there is no per-person tracking.

01

Customer-owned, customer-authorized — the organization owns the WiFi infrastructure and holds the legal basis for sensing within it.

02

Geofenced to controlled boundaries — sensing is confined to spaces the customer controls; coverage outside those boundaries is configured off.

03

Aggregate-only · no per-person tracking — consistent with ArGV3 Art. 26; the system records zone-level events, not individuals.

04

Swiss FADP · balancing of interests — each deployment carries a documented balancing-of-interests assessment and a Data Protection Impact Assessment (DPIA).

05

Through-wall, neighbor and public-space sensing is refused — explicitly out of scope, in the product and in contract. We do not build it.

Enforcement is in the product. The Authorized Deployment Registry records the authorizing organ and its mandate before any device is permitted to stream. No registered authorization, no data flow — the gate is technical, not just a policy promise.

05 · Use cases

Lawful, customer-owned contexts

Swiss B2B + government
perimeter · infrastructure
event security · dark sites

Where a camera is the wrong instrument. WiFi Sensing fits spaces that demand awareness without imaging — each tied to a lawful, customer-owned context with an authorizing organ on record.

Perimeter & border-zone intrusion

Movement detection across a mandated, customer-controlled perimeter — intrusion awareness without standing camera coverage of the zone.

Mandated · customer-controlled
Event-security occupancy

Live occupancy and crowd-movement state for an event in a venue the operator controls and consents to instrument.

Owner consent
Critical-infrastructure presence

Presence verification in restricted plant, utility and control rooms where imaging is undesirable or prohibited.

Restricted facility
Dark-site security

Motion and occupancy in unmanned or low-light facilities — sensing that works without a camera and without lighting the site.

Unmanned facility

Sensing that holds up to a Swiss legal review.

We will walk you through how it works, the on-site appliance, the aggregate-only data path, and the Authorized Deployment Registry — and exactly where the legal boundaries sit.
