Shielding decays.
Shielding decays.
Your threats don't wait.
A Faraday-shielded facility is the strongest physical tool for isolating RF energy — but humidity, settling, and construction changes open gaps long after certification day. Watch “RF Shielding: Building a Modern-Day Fortress from Existing Infrastructure” to see why physical isolation alone can't keep pace with what's actually in the building.

Certified shielding is a point-in-time measurement. Cracks, seals, and surface currents open channels that testing alone won't catch until the next scan.
The Physical Limit
A Faraday cage is the best tool you have. It's still not a permanent one.
Passive shielding stops working the moment its construction changes — and it always does.
Day 0 — Certified
The room passes emissions testing and is authorized to ICD-705 or equivalent standards.
Weeks in — Used
Furniture moves, cables get run, doors get serviced. Each change reshapes how the room collects and reflects RF.
Months in — Weathered
Humidity, temperature swings, and ground settling flex seals and joints in ways the original test never saw.
A year later — Unverified
Without a fresh scan, nobody actually knows whether the shield still holds — until something exploits the gap.
What Gets Through
The devices nobody thinks to look for
Real cases from the field show how ordinary equipment quietly carries a wireless interface into supposedly isolated spaces.
Undocumented Radios
The Bluetooth battery pack
A batch of commercial battery packs and power tools carried Bluetooth chips absent from their FCC filings — discovered only because they kept chirping during a routine sweep.
Vendor Drift
The "Bluetooth-free" door reader
A facility specifically procured RFID locks without Bluetooth. The units that arrived had it anyway, discovered only after wireless monitoring flagged new activity near the doors.
Bag Failure
The Faraday bag that wasn't
Off-the-shelf shielding bags used to transport devices failed emissions testing outright — trackers inside kept communicating straight through the fabric.
Range Myths
"Short-range" protocols aren't short-range anymore
Bluetooth's spec allows operating modes rated past a kilometer, and a basic Yagi antenna can double the practical range with no amplification at all. Add favorable terrain — or atmospheric ducting — and the numbers stretch further still.
- ↑ Bluetooth is spec-rated to reach beyond 1 km in certain modes
- ↑ Simple directional antennas roughly double effective range
- ↑ Bluetooth-to-satellite links have been demonstrated at LEO distances
- ↑ "Low energy" describes battery efficiency, not transmit power
Tens of billions
Bluetooth-capable devices estimated in the field today — badges, appliances, wearables, tools
125 kHz
Access card frequency that a concealed reader can clone from a normal walking pace, no contact required
20–30%
Swing in detection range that humidity and weather alone can introduce week to week
The Fix
Continuous detection closes the gap shielding can't
Scheduled scans give you a single point-in-time answer. Continuous RF monitoring gives you a baseline — and tells you the moment something drifts from it.
Baseline
Know what "normal" looks like
Ongoing collection builds a historical picture of your RF environment, so anomalies stand out instead of blending in.
Coverage
See Wi-Fi, Bluetooth, cellular, and LoRa
Emerging long-range protocols like LoRa and Meshtastic are harder to block passively — visibility has to come first.
Compliance
Support ICD-705 in the gaps
Where full retrofit isn't funded yet, active monitoring adds a verifiable layer while physical upgrades catch up.
