Origin

Born from a real failure.

The communication world

Four pillars. None of them carry the signal we actually need.

Modern safety still rides on four kinds of network. Every one of them was built for something else. Add them together and you still have the same hole.

  1. 01 Cellular

    Built for the density of phones, not the density of bodies.

    Towers saturate at mass-event scale. Indoor coverage collapses where the people are. Carrier priorities favor commercial traffic over emergency traffic.

  2. 02 Radio. 1944.

    Command-only by design. No user layer.

    Fragmented frequencies between agencies. Half-duplex protocols from before the transistor. The crowd is invisible to itself and invisible to command.

  3. 03 Wi-Fi

    Range bound. Infrastructure dependent.

    Useless outdoors and in motion. Dies the moment the venue's network dies. Built for the office floor, not the slope.

  4. 04 Satellite

    Latency. Cost. Line of sight.

    Indoor-blind. Slow to respond. Expensive per node. Irrelevant the moment you walk inside, where the people actually are.

  5. 05 The Gap

    None of the four connect the person to the command picture in real time.

    We carry the smartest devices ever built. Safety still depends on radios invented in 1944. Miss the golden hour after an incident and the chance of death rises 3.5x.

    dotSAGA is the missing layer
The stack

Four layers. One network.

Personnel, infrastructure, application, command. Each layer is independent and each layer reinforces the others.

L01 MyBand

Personnel layer

Ruggedized wearable mesh tag. One button. Screenless by design. Identity, location, and alert leave the device the moment it is pressed.

  • Screenless. Single physical button, optimized for the moment a person freezes.
  • Auto-pairs to the venue mesh. Zero configuration on the guest.
  • Identity, location, and time delivered on every press.
  • Runs without cellular, Wi-Fi, or satellite.

L02 NetAnchor

Infrastructure layer

RF mesh gateway network. Self-forming, self-healing. Holds the venue together when cellular, Wi-Fi, and satellite are gone.

  • Self-forming RF mesh. Anchors discover each other on power-up.
  • Self-healing. Survives node failure without losing the picture.
  • Independent of public networks. No carrier, no SIM, no cloud dependency.
  • Deployable across miles of terrain, indoors or out.

L03 MyCircle

User layer

Offline mobile application. Talks to MyBand and NetAnchor over the mesh. Works when the cell tower does not.

  • Offline-first. Works in airplane mode on any modern phone.
  • Talks to the mesh directly, no cell tower required.
  • Live view of your circle: family, team, unit.
  • One tap to alert. Position and identity arrive at command immediately.

L04 DotCommand

Intelligence layer

AI command center. Live picture of every node, every person, every alert. Movement patterns, density, stopped motion, everything that matters in the golden hour.

  • Live picture of every node on the network, with full attribution.
  • Anomaly detection on crowd density and stopped motion.
  • Replay any moment in the venue with timeline scrubbing.
  • Integrates with venue operations and tactical C2 systems.

One mesh. ×43 capacity. Same spectrum.

Today's communication infrastructure is fragmented across cellular, radio, Wi-Fi, and satellite. Each runs on its own protocol. Each fails on its own. The Versatile Spectrum Defender Node absorbs all four roles into a single self-forming mesh, then runs ×43 the capacity of a standard gateway on the same radio spectrum, with no extra hardware.

Today

Four networks. Four failure modes.

  • Cellular saturates at density
  • Radio is command-only, no user layer
  • Wi-Fi is range-bound, satellite is line-of-sight
  • Each network breaks on its own
With the VSDN

One network. Self-forming.

  • Every node forwards the signal
  • Self-healing on node failure
  • One protocol, end to end, no public network required
  • Live command picture from a single source of truth

Capacity in the same spectrum

Standard gateways stall at 8 channels. The VSDN runs 350.

Standard gateway (SX1302)

8 fixed channels. Hard ceiling.

  • Zero channel flooding. Fully eliminated.
  • Proprietary FPGA / SDR
×43 capacity. Same spectrum. Zero extra hardware.

VSDN. Versatile Spectrum Defender Node. Patent-pending. dot SAGA Ltd.

One chip

Same hardware. Three bodies.

MyBand is the same physical module wherever it ships. The form factor changes for the person wearing it. The protocol does not. The command picture does not.

  1. Defense

    Embedded any way the operator needs.

    Plate carrier. Helmet. Belt. Patch panel. The tag adapts to the kit the operator already carries. No exposed surface to snag, fail, or be lost in the field.

  2. Civilian

    Worn on the wrist.

    Screenless wearable on every guest. One press routes identity, location, and time to the command picture in milliseconds.

  3. Unmanned

    Built into the airframe.

    A module inside the drone's avionics. Broadcasts position into the mesh, recoverable on landing, ready for the next sortie.

Civilian. Mass events.

When the venue is bigger than the network.

A child skiing alone on an open alpine slope, the scale of the mountain dwarfing them.

Ski resorts. Music festivals. Outdoor camps. Theme parks. Wherever thousands of people share an environment that cellular was never built to cover, dotSAGA keeps every guest, every patrol, and every lift on the same picture.

  • Pilot signed with the 4th-largest US ski resort network for the 2026/27 winter season.
  • Discussions advancing with international operators in tourism, recreation, and large-venue management.
Same network, in contested environments
Defense. Tactical operations.

When the network is what you walked in with.

Contested environments. Jammed comms. Operators who arrive before the infrastructure does. dotSAGA's mesh is the network: self-forming, self-healing, alive the moment the first node powers up.

  • Active defense engagements with Israel MoD and a German defense partner.
  • Same hardware as the civilian deployment. Same protocol. Same command picture.
  • Survives node failure without losing the operational picture.
