Tactical relay & interoperability systems
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
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.
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.
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
One core system, three port configurations — plus two companion units that extend the network down to the platoon and into civilian fleets.
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.
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.
Maximum capacity for controlling remote sites — one unit consolidating a dozen radio channels under remote command and control.
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.
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
Brigade-and-below tactical networks, interoperability between maneuvering units, and UAV-borne airborne relay.
Units from different precincts and agencies — on different radio systems — patched into one operational net in minutes.
Coverage inside structures and terrain where direct links fail, and one net across every responding agency in a disaster.
Security fleets, mining, energy and remote operations that depend on radio where cellular never reaches.
Deployment
C4B units connect to the radios already in service — worn on a vest, strapped to a vehicle, or carried in a UAV payload.
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).
Continuous command & control across every connected unit, with remote control of relays from the command post.
