Whisperlinx Mesh

private off-grid communications

encrypted text messaging — simplified.
Built on Meshtastic. Governed by Whisperlinx.

When cell towers go down, storms hit, or the grid fails, you shouldn’t lose the ability to communicate with the people who matter most. Whisperlinx Mesh brings private, encrypted texting to families, farms, teams, neighborhoods, CERT groups, and anyone who wants reliable communication — without depending on the Internet.

No tinkering.
No configuration rabbit holes.
No guesswork.
Just secure digital communications that works when everything else doesn’t.

Why Off-Grid communications matters during emergencies

Most of us take cell phones and Internet for granted — until they fail.

And they do fail.

Winter storms and blizzards

Tornado outbreaks

Power grid failures

Rural dead zones

Overloaded cell towers during emergencies

Infrastructure failures

When communication is critical, you shouldn’t be left in the dark. Whisperlinx Mesh provides an independent way to exchange messages when other systems are unavailable.

Why Whisperlinx uses Meshtastic as its mesh transport

Shielded Signals evaluated multiple technologies before choosing the backbone for Whisperlinx Mesh. Meshtastic stood out because it is:

Proven and Stable

A large, active community constantly improves the software.

Efficient and long-range

LoRa radio technology makes it possible to send messages miles away using very little power.

Reliable in real-world conditions

It’s already used by hikers, ranchers, CERT teams, and off-grid communities.

Supported by a wide base of hardware

Availability matters! Customers shouldn’t have to hunt for parts.

How Shielded Signals builds on, but is Not, Meshtastic

Meshtastic is an amazing open-source project.
But it was designed for experimentation and flexibility—not for people who want a private communications system that “just works” without constant tuning..

These guarantees are enforced through the Whisperlinx Appliance, which governs membership, security policy, and trust within the mesh environment.

No Apps to Install

Connect with your phone, tablet, or laptop using wi-fi and a broswer. Done.

No confusing menus or settings

The appliance handles everything for you.

Always On Private channels

Each appliance is pre-configured to communicate only with other Whisperlinx appliances, giving you a private network of your own.

A hardened, curated experience

We manage the firmware, the encryption keys, the channel logic, and the reliability — not the customer.

Purpose-built for normal people

Families. Neighborhood groups. CERT teams. Small businesses. Preparedness groups.

Two Locks. One Message. Double encryption.

Most Meshtastic deployments rely on a single shared encryption key. Whisperlinx adds an additional, private encryption layer to ensure messages remain isolated to your group.

Meshtastic ChaCha20-Poly1305, 256-bit encryption (standard layer)

The encryption level available by default on all meshtastic traffic, and available to all nodes on the network.

Whisperlinx private key encryption (exclusive layer)

Your messages are:

Protected at the radio level

Protected again at the Whisperlinx Level

Isolated and private from anyone outside of your group

Unreadable to anyone not part of your ecosystem

It’s like having two locks on every message you send. Your communication stays YOURS.
