How the
wireless wire
works
Localized electric fields connect wearable devices, extend along conductive structures, and bridge short gaps.
The connection stays close to the system

Keep the signal local
Wi-R-enabled wearable devices communicate through a localized electric-field channel.

Wi-R BAN
Connect along
the structure
Use a suitable conductive structure as part of the communication channel between participating endpoints.
Sensors Compute
ControlThe structure and endpoint integration must be evaluated together.
Wi-R NFE
Bridge the
short gap
Connect two nearby devices with a localized electric-field link. Wi-R is integrated at both endpoints.
Gap, orientation, and enclosure design are configuration-specific.

Local processing in the glasses and additional pocket compute are two illustrative placements. Wi-R provides the link; the application determines how work is distributed.

Separate the data link from the control design
This is an illustrative architecture, not a certified control topology. Timing, fault response, power delivery, and integration across joints need system-specific evaluation.
Illustrative architectures, not deployed reference designs. Numbered leaders identify functional locations, not physical data cables.

A few practical questions
What needs to be integrated at each endpoint?
Each participating device needs a Wi-R interface and the host integration appropriate to the chosen product. Start with the relevant product documentation and evaluation hardware.
Does the data link also deliver wireless power?
Data connectivity and power delivery are separate design questions. Evaluate the power requirements of each endpoint in your configuration.
How should I compare rate, power, and range?
Compare identified products at stated operating points. Distinguish raw data rate from application throughput and IC energy from system power. Treat distance along a structure, distance away from it, and the gap between NFE devices as separate measurements.
Can an existing phone join without modification?
Participating endpoints need the corresponding Wi-R integration or an appropriate external interface. An unmodified phone or wearable does not automatically join the system.
EVALUATE Wi-R
What needs
to connect?
Tell us which endpoints need to connect, what data they carry, and what physical constraints apply. Start with your architecture, then choose the silicon.
