5 Mbit/s Near-Field Links at Sub-Milliwatt Power
Contained electric fields of Near-Field Electric (NFE) keep communication near the device for fast predictable interaction within arm’s reach

Range between devices
How NFE works
Wi-R NFE uses a contained electric field to couple two powered devices at close range. Signal stays near the device, creating a physically local link that feels immediate and avoids room-scale broadcast. Range is within arm's reach and depends on orientation and setup.

Evidence for design decisions
Low Power, Extended Range
Lowest device power and tap‑to‑arm's‑length range
Configurable Range
Range varies with orientation and data rate
Along-Conductor Communication
Conductive surfaces can extend effective NFE range to 1m
How NFE compares to near-field alternatives
| Tech | Typical Power | Data Rate | Range | Best Fit |
|---|---|---|---|---|
| Wi-R NFE | sub-milliwatt class | 5 Mbit/s | 5-30cm | Provisioning, sealed devices, local data |
| NFC | reader high, endpoint passive | ~0.4 Mbit/s | ~4 cm | Payments, tap |
| NFMI | mW-class | ~0.6 Mbit/s | ~1-3 m | Legacy ear-to-ear |
| 60 GHz | tens of mW | multi-Gbit/s | short LoS | High-rate connectors |
Typical device power refers to two-way powered devices unless noted. NFC row reflects reader/endpoint power asymmetry.

NFE couples two powered devices using a contained electric field. It is designed for touch‑to‑arm’s‑length workflows where you want deterministic, low‑power links without room‑scale broadcast. Use it instead of NFC when you want higher throughput and lower device‑side power, and instead of NFMI or 60 GHz when you want sub‑milliwatt budgets at near‑field range.
