Tactical relay & interoperability systems

Every radio you own becomes one network

C4Bridge attaches to the radios your forces already carry — different vendors, different bands, different decades — and welds them into a self-healing tactical network. No replacement fleet. No fixed infrastructure. Combat proven since 2010.

Technology

Intelligence on top of the radios you already fielded

A smart switch analyzes and manages every transmission its connected radio receives — turning any radio in the network into a dynamic relay station or a network processor.

The problem

Tactical radio drops constantly: terrain, obstacles, interference, jamming. When a unit goes silent, coordination, fire support and evacuation all stall. And the world's radio fleets are aging — full migration to software-defined radio takes years and budgets most forces don't have.

The approach

Keep the fleet. Add a C4B unit where it matters and the network gains ad-hoc networking, cross-vendor interoperability, remote control and continuous command & control — automatically, with no operator workload. Different agencies on different protocols talk on one net.

Products

The C4Bridge family

One core system, three port configurations — plus two companion units that extend the network down to the platoon and into civilian fleets.

Flagship — combat proven since 2010
4ports

C4B4

The most compact interoperability system in the family. A software-defined relay that interfaces with all deployed radios and phones. Portable, rugged, worn on a vest or mounted in a UAV payload.

Portable integrator
8ports

C4B8

The balance of portability and capacity. A rugged communication integrator that sits on top of currently deployed radios — bridging a multi-agency operation with no fixed infrastructure.

Remote sites
12ports

C4B12

Maximum capacity for controlling remote sites — one unit consolidating a dozen radio channels under remote command and control.

PLT
LEVEL

DRS Micro

The platoon commander's unit. One C4Bridge at company command, one Micro per platoon — and a platoon that loses its direct link is re-routed through whoever still hears both sides. No manual message relaying.

PTT
EMBED

DRS Pico

The full DRS feature set embedded inside the push-to-talk microphone switch of existing civilian radios. Attach it and a police, fire or industrial fleet gains ad-hoc networking and interoperability instantly.

Sectors

One system, every force

CH 01

Military

Brigade-and-below tactical networks, interoperability between maneuvering units, and UAV-borne airborne relay.

CH 02

Police

Units from different precincts and agencies — on different radio systems — patched into one operational net in minutes.

CH 03

Fire & rescue

Coverage inside structures and terrain where direct links fail, and one net across every responding agency in a disaster.

CH 04

Private & industry

Security fleets, mining, energy and remote operations that depend on radio where cellular never reaches.

Deployment

Fielded in three steps

STEP 01

Attach

C4B units connect to the radios already in service — worn on a vest, strapped to a vehicle, or carried in a UAV payload.

STEP 02

The network forms

Units become smart relays automatically. Broken links re-route through whoever still has reception — beyond line of sight, on one or two channels (F1-F1 / F1-F2).

STEP 03

Command sees everything

Continuous command & control across every connected unit, with remote control of relays from the command post.

Contact

Bring your radios. Leave with one network.

A live demonstration takes one hour and runs on your own deployed equipment — no preparation required on your side.
