Private by design. Everything is encrypted on your device before it leaves. LCS Global only relays encrypted packets — it cannot read them, and never needs your name, number or email.

What is Reticulum?

An open-source self-configuring mesh networking software stack that works over multiple interfaces

The Reticulum Network Stack — the open-source project our hardware runs on.

Reticulum is the networking stack underneath everything we sell. It is not an app and not a radio — it is the software that decides how a message gets from you to someone else, over whatever interfaces you happen to have: a LoRa radio, a VHF or UHF packet link, the Wi-Fi in a room, an Ethernet cable, or LCS Global when you want the world. Every node announces itself, every node learns the paths, and the network configures itself. There are no addresses to hand out, no servers to depend on, and nothing to subscribe to.

Everything is encrypted end to end, by default, with keys that live on your own devices. A destination’s address is its public key fingerprint, so there is nobody in the middle to trust, and no account to register. Reticulum needs no IP address, no DNS and no internet connection to work — and when a link does cross the internet, the same encryption still applies.

The finer details — encryption, addressing, routing, transport and propagation nodes

The encryption, exactly

Signatures
Ed25519

Key exchange
X25519 · ECDH on Curve25519

Key derivation
HKDF

Encryption
AES-256 · CBC mode · PKCS7 padding

Authentication
HMAC-SHA256

Hashing
SHA-256 and SHA-512

Addresses
128-bit truncated SHA-256

Forward secrecy
Ephemeral keys for every Link

Encrypted tokens follow the Fernet design, without its version and timestamp fields; every IV comes from the operating system’s secure random source. In a standard install, OpenSSL — through the PyCA cryptography package — performs the X25519, Ed25519 and AES-256 operations.

Functions without IP addressing, although it can be tunneled over TCP/IP.
Independence. 32-digit hash-based identities are generated by each instance of Reticulum and are independent of central registrars that can lock users out at will.
Uncentralized. The network is built by anyone operating a node.
Intelligent multi-hop transport routing over whatever interfaces are available. Every user contributes to the delivery path as a transport node or repeater; messages take the most direct route.
Peers are discovered through an announce mechanism, or by entering a hash identity so the path is found.
Text, data and voice all travel on the one network.
Secure communications reduce surveillance. The source address is kept anonymous and messages are AES-256 CBC end-to-end encrypted.
Open source. Developed by Mark Qvist and released to the public in 2016.
Built for bad links. It works over connections measured in a few hundred bits per second, which is what makes long-range LoRa and HF usable for real messages.

Transport nodeA Reticulum instance that has been told to carry other people’s traffic. It learns the paths from the announces it hears and relays packets onward — between two radios, or from a radio onto Wi-Fi or LCS Global — so two people who cannot hear each other directly can still talk. Our Solar Transport RNodes are transport nodes, and so is every Command Center PRO. The apps can act as one too.

Propagation nodeA transport node that also stores messages. When the person you are writing to is switched off or out of range, a propagation node holds the message and hands it over the moment they come back on the network — the mesh equivalent of a mail server, with no mail server. The Command Center PRO runs one for your whole network.

Add Interfaces

Build your local network. An interface is simply a way for Reticulum to carry traffic — switch on the ones you have, as many at once as you like

Once your app is installed, add a radio on each side to start communicating locally. To build a larger network, add repeaters in strategic places — rooftops, silos, mountain overlooks. Get the Command Center PRO to reach the next town over VHF/UHF radio. And when you want the whole world, switch on LCS Global. With transport enabled, traffic moves freely between whichever interfaces are running.

LoRa

Long-range radio, no licence. 902–928 MHz, from 183 bps to 21.9 kbps depending on the preset. A mile or so between handhelds; many more with a transport node up high.

LoRa presets

Every radio on a network must use the same preset. All of these run on 914.875 MHz; pick one in the app’s RNode settings and set every radio to match. Faster presets carry voice and pictures well over short distances; slower ones reach much further.

Preset	Spreading factor	Bandwidth	Coding rate	Speed (approx.)	Good for
Short Turbo	SF7	500 kHz	4/5	21.9 kbps	Fastest; very short range
Short Fast	SF7	250 kHz	4/5	10.9 kbps	Best for voice over LoRa
Short Slow	SF8	250 kHz	4/5	6.2 kbps	Good range and speed with high repeaters
Medium Fast	SF9	250 kHz	4/5	3.5 kbps	Good range and speed with high repeaters
Medium Slow	SF10	250 kHz	4/5	2.0 kbps	Good range and speed with high repeaters
Long Range / Turbo	SF11	500 kHz	4/8	1.3 kbps	Wide channel at a high spreading factor
Long Fast	SF11	250 kHz	4/5	1.1 kbps	Default — a good balance in dense terrain
Long Moderate	SF11	125 kHz	4/8	336 bps	Better range, slower
Long Slow	SF12	125 kHz	4/8	183 bps	Maximum range, slowest

Speed is the raw LoRa data rate; real throughput is a little lower. Range depends far more on antenna height and terrain than on any setting.

Notice — Radio frequency spectrum is a legally controlled resource and legislation varies widely around the world. It is your responsibility to be aware of any relevant regulation for your location, and to make decisions accordingly.

Two client nodes give you a conversation. Add a transport node somewhere high — a roof, a ridge, a treeline — and you have a network that covers ground. A Command Center PRO turns that into a station the whole household can use, holds messages for anyone who is offline, and bridges the LoRa mesh to Wi-Fi, packet radio and LCS Global. The pills show which interfaces each radio gives you.

How the encryption works

Liberty Chat and LCS MeshChat run on Reticulum. Every message, call and file is encrypted on your device for the one person it's going to, before it leaves: X25519 elliptic-curve key exchange, Ed25519 signatures, and AES-256 encryption (CBC mode) authenticated with HMAC-SHA256.

Calls and file transfers run over Reticulum links, which make fresh keys for every session, so a key taken later can't unlock what was sent before (forward secrecy). Your private key never leaves your device.

LCS Global only carries the encrypted packets between you and the rest of the network. It can't read them, and it doesn't need your name, phone number or email to work.

About Liberty Communication Systems

Liberty Communication Systems, Inc. builds off-grid mesh networking hardware that lets people communicate securely and reliably without depending on anybody’s infrastructure. Our devices run the Reticulum stack across LoRa, packet radio, Wi-Fi, Ethernet and IP at the same time, and they are assembled, flashed and tested here before they ship.

We believe communication should not depend on a tower, a subscription or a company’s goodwill. Whether you are on a remote homestead, working through an outage, or simply would rather not route your conversations through somebody else’s servers, the hardware on this page is built to keep working — and to keep costing nothing to use once you own it. LCS Global is there when you want to reach the rest of the world; it is never required.
