Nobody is watching the spectrum. We are.
Guardian RF is a network of low-cost edge sensors that learns the normal radio environment around your site and flags jammers, GPS interference and unknown transmitters the moment they appear. It runs fully offline, and every detection is sealed into a tamper-evident record.
Proven in the field, not just the lab.
From six months of continuous deployment in Quesnel, British Columbia, including a mobile mesh test along Highway 97.
Critical sites watch the fence line. Almost none watch the airwaves.
Substations, airports, border crossings and correctional facilities already have cameras, fences and guards. But the first sign of a jammer, a spoofed GPS signal or an unregistered transmitter shows up on the radio spectrum — and on most sites, nothing is listening.
Jamming
Deliberate noise that drowns out radios, navigation and wireless links. Guardian RF sees the noise floor rise before systems fail.
GPS interference
Interference on satellite navigation bands can mislead navigation and timing systems near runways, ports and grid assets.
Unknown transmitters
Devices broadcasting where nothing should be. Flagged and cross-referenced against public spectrum licence records.
Link interference
SCADA, telemetry and radio links degraded by unexplained RF activity — caught continuously, not on a sweep schedule.
Four steps from antenna to action.
Learn
Each node learns its own site's radio noise floor, band by band, from a rolling 60-sample baseline.
Detect
Signals that drift past configurable Z-score thresholds are flagged HIGH_RSSI or LOW_RSSI in under 400 ms, on the device.
Seal
Every flag is timestamped and written to an immutable local ledger. Nothing leaves the site unless you configure it to.
Escalate
Critical deviations open an incident and queue a dispatch order in the field dashboard. A person reviews it with one tap.
Three node types. One sovereign mesh.
Guardian RF runs on commercial off-the-shelf software-defined radio hardware, so covering a site densely costs a fraction of traditional spectrum equipment.
Alpha
Fixed sentinel node- 24/7 stationary spectrum watch
- Detection runs on the device, no network needed
- Bootable recovery USB restores it in minutes
Rover
Mobile survey unit- Handheld or vehicle-mounted
- Maps interference along routes and perimeters
- Field-tested on a Highway 97 mobile mesh
Hub
On-site compute & storage- Aggregates node data inside your perimeter
- Local storage and analysis, no cloud
- Forwards sealed records to the vault
Your spectrum data never touches the public internet.
Cloud-hosted monitoring means trusting someone else's servers with a map of your site's radio activity. Guardian RF keeps capture, detection and storage on hardware you control, from edge to vault.
Guardian RF node
Captures the spectrum and runs detection on the device. Raw captures and telemetry stay sealed locally.
Sovereign relay
An air-gapped relay batches validated events and forwards them across an encrypted private mesh. The edge node stays invisible to the internet.
AsterionDB vault
An Oracle-based vault stores each event with cryptographic provenance and a full chain of custody — tamper-evident and forensically searchable.
No cloud dependency
Works in dead zones, remote sites and air-gapped facilities.
Your data, your property
Raw spectral data stays on your hardware unless you choose to send an alert.
Recovery-ready
A bootable USB restores a node in minutes. No cloud restore, no vendor lock-in.
Built for sites where the spectrum matters.

What's running today, and what's next.
We'd rather show you real field data than a glossy roadmap. Here is exactly where Guardian RF stands.
Continuous deployment in Quesnel, BC
Six months of real operational data from fixed and mobile nodes, over 43,000 logged anomalies, and a mobile mesh test along Highway 97.
Cryptographic data vault with AsterionDB
A formal partnership with AsterionDB Inc. of Los Angeles. Our teams meet weekly to integrate the vault layer into the Guardian RF pipeline.
Custom RF carrier board
A purpose-built circuit board to take Guardian RF nodes from field prototype to repeatable production.
See your site before you sign anything.
We build a simulation of your site and the threats you worry about. You run it on your own hardware, with no cloud, and watch Guardian RF detect, escalate and recover in real time. Free for qualified organizations.
The full Site Check fee is credited toward your next step. Prices in CAD.

Request the brief →What is Guardian RF?+
An edge-based RF anomaly detection network. Low-cost sensor nodes learn the normal radio environment around a site, flag statistical deviations in real time and seal every event into a tamper-evident record, without relying on the cloud.
Does it need an internet connection?+
No. Capture, detection and storage all run on hardware at your site, so it works in dead zones, remote locations and air-gapped facilities. Outbound alerting is optional and stays off unless you configure it.
What hardware does it run on?+
Commercial off-the-shelf software-defined radio (SDR) hardware running Linux, which keeps the cost per monitored point low. A custom RF carrier board for production nodes is in development.
Does it record conversations or message content?+
Guardian RF detects anomalies from signal characteristics such as frequency, strength and timing. It is built to tell you that something unexpected is transmitting, not what is being said.
How does a trial work?+
After a 15-minute call about your site and the threats you care about, we build a custom scenario pack that runs on your own hardware. It's free for qualified organizations. If it holds up, the next step is a $395 Site Check.
Who is behind AceGuardian?+
AceGuardian AI Pro Inc. is a Canadian company based in Quesnel, British Columbia, founded by Paul Langlois after more than two decades working on hydro transmission lines, remote oil and gas sites and logging operations. The vault layer is built with partner AsterionDB.
