Wi-Fi sensing · Edge AISilverPulse

Every room, aware.

The Wi-Fi already in the room detects presence and falls, and alerts care staff. No cameras, no wearables.

Why it matters01 / 07

In care homes, night shifts are thin and rooms are many.

1 in 5

people over 65 in Italy fell at least once in the past year. In care homes the risk peaks at night, when fewer staff are on the floor and no one is in the room.

A

Cameras

cost residents their privacy, and in workplaces they are restricted by Italian labour law.

B

Wearables

get forgotten, removed or refused.

C

A third way.

The Wi-Fi already in the room.


The signal02 / 07

Every Wi-Fi signal that crosses a room is distorted by what happens inside it.

A person walking, sitting down, breathing or falling changes how the signal travels, subcarrier by subcarrier. We read those changes.

Subcarriers ↓Time →

Channel State Information (CSI): human activity, without a single image.

01

Wi-Fi signal

Small nodes read how the Wi-Fi signal changes inside the room.

02

Local analysis

An Edge AI model recognises events such as falls or long absences from bed, on site.

03

Staff alert

A carer gets the alert and goes to check. A person always makes the call.


What we are building03 / 07

Three signals, one goal: noticing in time.

  1. 01

    Fall detection

    and immediate alerts for care staff

    In development
  2. 02

    Presence & activity

    bed exits and long absences, including at night

    In development
  3. 03

    Respiratory patterns

    as a non-contact wellbeing signal

    Research

SilverPulse is not a medical device: it flags events to be checked, it does not diagnose. We will not publish accuracy figures until we have measured them in the field with our partner sites.

Where04 / 07

Two settings, one need: nobody should be left on the floor without anyone knowing.

Nursing homes · assisted living

Care homes

Night shifts, reduced staff, many rooms to watch. Alerts for falls, bed exits and long absences, with no image of residents.

Warehouses · labs · off-hours shifts

Lone workers

We detect a “person down” event, not productivity. A safety system, not a surveillance one, introduced through the procedures required by Italian labour law.

No cameras.
No wearables.
No construction work.
The platform05 / 07

A control room for the people who care.

Room status, alerts and event history in a single view, designed for the night shift.

Site map

Every room and its status, floor by floor.

Alert centre

Who took it, what happened, and the full history of each event.

Reports

Night-by-night trends for coordinators and management.


Privacy by design06 / 07

Privacy is our starting point.

No images are captured. Data is processed locally.

No cameras, no microphones

We only use the Wi-Fi signal. There is no image of a resident, not even by mistake.

Raw signal stays on site

Analysis runs locally. Only events reach the platform, never the signal data.

Shared DPIA before installing

A data protection impact assessment prepared with your DPO before any installation.

Resident safety, not staff monitoring

The system tracks safety events. It does not measure staff time or activity.


Where we are07 / 07

From pilot to every home.

Today we run pilots with dedicated nodes to validate the system in the field. The goal is to run the same software inside routers, with no extra hardware.

Today

Pilots with dedicated nodes

Small Wi-Fi nodes placed next to the site’s network, no construction work. They validate the system and train the models with 3–4 partner sites in Lombardy.

Next

Inside the router

The same software on access points and routers, together with network operators. Nothing extra to install.

Goal

In every home

A safety service for people living alone, switched on through the connection they already have.
