Ravens: Self-Reporting Asset Beacons

Attach a Raven to any asset and it reports its own location to Forager on a schedule or when moved: automatically, with no staff involvement and no connection to your corporate network.

Named for Huginn and Muninn

In Norse mythology, Odin's ravens flew out each morning to observe the world and returned to report everything they had seen. These devices do exactly that: attach one to any asset and it scouts its own location on a schedule or whenever in motion, while the rest of your operation runs without interruption.

How Ravens work.

  • 1. Wake
  • 2. Scan
  • 3. Report
  • 4. Sleep
On a configurable schedule, or when the asset is moved, the Raven wakes from deep sleep. Motion sensing lets it report while the asset is in transit and rest when it's parked, so the battery budget goes where the movement is. No staff trigger required.
The Raven passively reads the ambient RF environment: the Wi-Fi access points and BLE devices visible from wherever it is. It never connects to the network, never authenticates, never transmits on the hospital's infrastructure. It just listens and records what the radio environment looks like from that location.
The Raven sends its scan data to a nearby Gateway, a small device installed in the drop ceiling of a hallway. The Gateway routes the payload to the Forager backend over a cellular connection. Forager compares the scan against its RF fingerprint database and estimates which room the asset is in, with a confidence score attached. The asset's location record updates automatically, and the confidence travels with it.
Transmission complete, the Raven returns to deep sleep until its next scheduled wake. Power draw during sleep is negligible by design: Ravens are built around a single sealed primary battery sized for years of service, with no charging, no outlet, and no battery-swap rounds on your maintenance calendar.
Ravens are RF environment sensors, not simple identifier beacons. The difference matters: an identifier beacon tells you "this tag is somewhere in this building." A Raven gives Forager the evidence to place the asset in a specific room, because it reads the same ambient RF signals that Forager's fingerprint database was built from.

No network integration required. Ravens don't touch your corporate infrastructure. No IT approval. No InfoSec review. No VLAN allocation. Plug in a Gateway, attach Ravens to assets, and location data starts flowing.

What you're installing
01
Ravens (asset nodes)
Matchbox-sized beacons that attach to any asset with a cable tie or adhesive pad. Powered by a long-life primary battery designed for years of service with no charging. Sealed, wipeable enclosure designed for hospital cleaning agents. No tools required for installation.
02
Gateways (ceiling nodes)
Small AC-powered devices installed in drop ceilings or mounted high on hallway walls. Each Gateway serves a coverage area, receives scan data from Ravens nearby, and routes it to the Forager backend over cellular, independent of your corporate network. One hardware design carries every capability; software licensing unlocks more as you need it.

Installation takes hours, not months.

Gateway approval goes through Facilities, not InfoSec. Attaching Ravens to assets requires no credentials, no programmer, and no IT involvement. A technician with a phone and a bag of Ravens can cover a floor in an afternoon.

Where Ravens earn their keep.

Forager's manual presence confirmation is fast and effective for assets your team visits regularly. Ravens extend that coverage to the assets that fall through the cracks.

High-movement assets

Carts, portable equipment, and shared devices that change locations multiple times a day. Manual confirmation can't keep up. Ravens report in continuously without anyone picking up a phone.

Hard-to-reach locations

Equipment in storage rooms, back-of-house areas, and maintenance closets that staff rarely pass through. Ravens keep location records current between visits, even for assets that go untouched for weeks.

High-value assets

For equipment where continuous location awareness justifies the hardware cost (infusion pumps, imaging accessories, specialty carts), Ravens provide ongoing presence reporting instead of point-in-time snapshots.

Compliance-critical inventory

Assets that must be located on demand for audits and inspections. A Raven-tracked asset has a location record as fresh as the schedule you set, not "last confirmed by a tech three weeks ago."

Lean staffing environments

Facilities where manual scan cadence is limited by headcount. Ravens operate regardless of scheduling, staffing levels, or shift coverage; location data doesn't depend on a person walking the floor.

After-hours monitoring

Ravens scan on schedule around the clock. Overnight movement of an asset that shouldn't be moving is visible in the dashboard the next morning, without anyone being on-site to observe it.

One Raven. One Gateway. Software does the rest.

No model lineup to decode and no wrong hardware to get stuck with. Every Raven and every Gateway ships with the full hardware capability built in; what each one does is set in software, per site, from the platform.
The tag

Raven

One matchbox-sized beacon design for every environment. Sealed primary battery designed for years of service, no charging, no outlet. The platform tunes each Raven's sensing behavior to its surroundings automatically, so a Raven moved between areas keeps doing the right thing without anyone touching it.

Attach it with a cable tie or adhesive pad, provision it with an NFC tap, and forget it.

The infrastructure

Gateway

One AC-powered ceiling unit carries every capability: cellular backhaul, Raven relay, and advanced location features. Capabilities unlock by software license, not by hardware swap, so you can start with basic relay coverage and add more later without touching the ceiling.

Installed by Facilities, connected over cellular, invisible to your corporate network.

Ravens extend your Forager deployment.

Ravens don't replace Forager's manual presence confirmation workflow; they extend it. From the Forager dashboard's perspective, a Raven update and a staff member scan are the same type of event: asset confirmed in room, timestamp, source attributed.

The same floor plan visualizations, compliance reports, and attestation logs that Forager already generates work identically for Raven-tracked assets. No new dashboard. No separate system. No parallel database.

If you're already running a Forager deployment, Ravens add continuous coverage on top of the RF fingerprint infrastructure you've already built. The rooms you've surveyed are immediately available for Raven location matching: no additional setup required.
