RuBee® · IEEE 1902.1 · Magnetic Wireless

Not Radio. Magnetic.
Reads Through Steel.
Works Underwater.

RuBee (IEEE 1902.1) is a packet-based wireless technology that uses the magnetic spectrum instead of radio. Active tags with a field-proven 5–25 year battery life deliver 100% read accuracy in the high-steel, high-noise, high-security environments where RF and RFID fail.

The Impossible Demo — a tag read through sealed nuclear-grade steel

A RuBee tag read from inside a sealed nuclear steel containment vessel — a live demonstration no radio-frequency technology can perform. Documented in US DOE laboratory reports.

Why RuBee®

RuBee is designed for high security, high human safety, high intrinsic safety, and high-noise harsh environments — the Defense and Industrial Internet of Things requirements no other wireless meets.

5–25 Year Battery

Field-proven battery life with a range of 1 to 50 feet, on simple coin-size lithium cells.

Sealed & Waterproof

Tags are sealed to MIL-STD 810 and waterproof to 5,000 feet.

A Computer, Not a Label

Every tag carries a CPU, memory, a clock, and optional sensors with data logging.

Physically Secure

No compromising emanations — no Tempest, target, or eavesdropping risk. The only wireless allowed in DOE secure areas.

HERO ZERO · HERF ZERO

The only wireless technology safe on and near explosives, with a zero Safe Separation Distance.

Human Safe

FDA-classified Class 1, Non-Significant Risk — about one million times below OSHA limits.

Immune to Steel & Noise

Magnetic fields have no multi-path nulls. 100% accuracy where RF is compromised.

Reads Through Anything

Not blocked by steel, liquids, dirt, snow, or people. Volumetric reads, no line-of-sight.

Steel Is Not the Problem.
Steel Is the Antenna.

RuBee tags can be attached to or embedded in any steel product — a jet engine, a guidance system, structural aircraft parts. RuBee turns the steel itself into a high-performance tuned antenna with 100% reliable read accuracy. Tags are read in a volume, not a line of sight, and are intrinsically safe in explosive environments.

DoorGuard xP

Ten-minute install; blocks accidental cell phone and sensitive-item entry into secure areas.

Explosive Stores

Store 20/20 with the ATLAS antenna system delivers automated audits, inventory, and high security for explosive stores — where every other wireless is prohibited outright. HERO ZERO and HERF ZERO, zero Safe Separation Distance.

The Impossible Demos

A RuBee tag read from inside a sealed nuclear steel containment vessel. A tag on a steel I-beam read underwater — through steel and water at the same time. Both documented in US DOE laboratory reports.

Prognostic Health Management

RuBee® PHM — The Health Tag

The first working PHM system for sealed, sensitive assets: an asset tag that records the whole life of the item, and the software that turns the record into decisions. Six sensors — temperature, humidity, pressure, 3-axis shock to ±200 g, vibration spectrum, motion — on a 15- or 25-year cell, sealed inside the case with the asset. Sensor Envoy reads a whole group through closed containers in one discovery session, flags what needs attention, and writes the reports.

  • ✓ Every excursion with start, end and worst value
  • ✓ 15 shock traces, 3-axis at 6400 Hz
  • ✓ Cumulative vibration PSD by frequency and axis
  • ✓ Inventory scans and PHM from the same tag
Real Envoy shock trace from a Health Tag: 125.8 g peak, X Y Z over 16 ms
Real Envoy output — 125.8 g shock, X/Y/Z, 16 ms
Cumulative vibration power spectral density from a Health Tag
Cumulative vibration PSD — lifetime energy by frequency
