C-AT is a Service-Disabled Veteran-Owned Small Business (SDVOSB) providing standard and custom communication systems, engineering support, integration, and long-term product support.
C-AT designs and manufactures standard and custom communication systems for public safety, defense, emergency response, hazardous operations, secure facilities, and other demanding environments.
Our work includes radio interoperability, vehicle intercom and crew communications, communication systems for personnel working in PPE, and specialized systems engineered around the customer’s equipment, facility, security requirements, and operational needs.
C-AT systems can also be integrated across a secure site or facility using local and hard-wired connections where required.
This allows radio users, vehicle crews, HazMat personnel, command staff, and other operators to communicate across an integrated system without requiring internet connectivity for the local communications path.
This architecture can support closed-site, controlled-access, HEMP-protected, and other specialized facilities where communications must operate within the site’s established security and infrastructure requirements.
C-AT capabilities include:
Radio interoperability and interoperable communications across different radio systems, manufacturers, frequencies, and networks
Vehicle intercom and crew communication systems for military, public safety, emergency response, command, and specialty vehicles
Hazardous-environment and PPE communication systems for personnel working in protective equipment
Secure-site and closed-network communications using local and hard-wired integration where required
Communications integration for HEMP-protected and other specialized facilities
Custom communication system engineering and integration for facilities, vehicles, operational platforms, and specialized mission requirements
Radio, headset, cabling, dispatch, SATCOM, and accessory integration for existing and new communication technologies
When a standard C-AT system meets the requirement, we provide it.
When it does not, C-AT can engineer the communications architecture around the people, radios, vehicles, protective equipment, facility, security requirements, and operating environment.
C-AT connects communication systems that were not necessarily designed to work together. That gives agencies and operational teams more flexibility to use the radios, networks, vehicles, applications, and equipment they already have instead of rebuilding the entire communications environment around a single manufacturer or platform.
ICRI creates interoperability across otherwise incompatible communication systems. Different Land Mobile Radios can communicate through the same system, and ICRI can also connect radios with push-to-talk-over-cellular applications, smartphones, SATCOM, dispatch systems, MANET networks, and other communication technologies.
Organizations can add interoperability without requiring every user, radio, or agency to operate on the same platform.
From there, the possibilities expand:
LMR-to-SATCOM and BLOS communications can extend radio communications beyond normal terrestrial coverage.
CSCK, the C-AT Signal Continuity Kit, can extend communications into confined, below-grade, and difficult RF environments.
Responder Ready Elevate provides a drone-deployable interoperability option that can place the communications node at elevation when terrain, structures, or distance limit coverage.
ComForce provides vehicle intercom and crew communications while connecting operators to multiple radios and external communication systems.
When integrated with ICRI, the vehicle becomes part of the larger interoperable communications network. Vehicle crews can communicate beyond the vehicle with radio users, command personnel, other agencies, and connected communication platforms.
WIS brings communications to personnel working in protective equipment and hazardous environments.
When integrated into the broader C-AT communications architecture, HazMat personnel can communicate with radio users, vehicle crews, command staff, and other operational teams rather than operating on an isolated communications system.
C-AT can bring radios, smartphones, PTT applications, SATCOM, vehicle intercoms, HazMat communications, dispatch systems, and deployable communication technologies into one interoperable communications environment.
Build communications around the operation instead of building the operation around one communications platform.
The ICRI is a modular radio interoperability system that connects otherwise incompatible communication platforms.
ICRI systems can integrate:
The ICRI is designed for planned operations, emergency response, multi-agency coordination, continuity events, and infrastructure-failure scenarios.
The ICRI’s modular, stackable architecture enables agencies to configure the system around the number of radios, devices, talk groups, and operational roles required for the incident.
Local radio interoperability does not have to depend on internet connectivity.
No radio reprogramming. No recurring subscription required for baseline interoperability.
C-AT develops custom ICRI configurations for unique radio, dispatch, SATCOM, and network requirements.
C-AT ComForce is a radio-agnostic and headset-agnostic vehicle intercom system for military, public safety, fire and rescue, emergency response, command, tactical, and specialty vehicles.
ComForce connects crew members and multiple radios into one controlled communication environment.
Each crew position uses an individual Intercom Control Unit for:
Radio selection and transmission
Full-duplex crew intercom
Independent audio control
Simultaneous crew and radio coordination
Glove-accessible operation
ComForce can integrate with:
Tactical and Land Mobile Radios
SATCOM radios
Mesh and MANET systems
Aviation radios
Analog and digital radio systems
Existing and emerging communication equipment
Available configurations include:
ComForce 5.2: up to five users and two radios
ComForce 10.2: up to ten users and two radios
ComForce 10.4: up to ten users and four radios
Systems are configured around the vehicle platform, crew structure, radios, headsets, and operational requirement. C-AT can also engineer custom vehicle communication configurations when a standard system does not fully meet the need.
When integrated with ICRI, ComForce can extend the vehicle into a broader interoperable communications environment, connecting the crew with other radio users, agencies, command personnel, and supported communication platforms.
The C-AT Wireless Intercom System (WIS) is designed for personnel working in Level A and Level B protective suits, SCBA, respirators, PAPR and CAPR systems, and other PPE used in hazardous environments.
WIS can be configured around the protective equipment, radios, facility, and operating procedures.
WIS supports two communication approaches:
Hands-free, full-duplex communication using C-AT WIS radios and the C-AT accelerometer-based throat microphone
Large-button push-to-talk for compatible existing radios, providing glove-accessible operation when half-duplex communication is appropriate
Organizations can select the approach that best fits the work, equipment, and operational requirement.
WIS has more than a decade of use in demanding hazardous environments, including chemical weapons destruction operations.
Applications include:
Chemical weapons destruction and demilitarization
Hydrazine and hypergolic fueling
Nuclear and radiological operations
Chemical processing and hazardous material handling
HAZMAT and CBRN/CBRNE operations
Industrial maintenance and decontamination
Confined and controlled hazardous work environments
WIS is available in fixed-facility and portable configurations and can connect suited personnel with supervisors, control rooms, and operational teams.
When broader interoperability is needed, WIS can integrate through ICRI, connecting personnel in PPE with Land Mobile Radios, incident command, facility communications, vehicle crews, and other radio networks.
C-AT can extend Land Mobile Radio communications beyond traditional terrestrial coverage by integrating ICRI with SATCOM and other beyond-line-of-sight (BLOS) communication technologies.
This allows existing radio users to remain on the equipment and workflows they already use while connecting to personnel or command locations well beyond normal radio range.
Depending on the requirement, C-AT can integrate:
Land Mobile Radio to SATCOM
BLOS communications
Satellite communication systems
Push-to-talk-over-cellular platforms
MANET and other communication networks
Remote command and dispatch communications
And because ICRI can also integrate with ComForce and WIS, extended communications can reach beyond handheld radio users to include vehicle crews, personnel working in PPE, command teams, and other connected users.
C-AT configures the communications path around the existing equipment, available transport, operating environment, and mission requirement.
Organizations often have years of investment in radios, vehicles, headsets, dispatch systems, and other communication equipment. C-AT helps connect those existing technologies while adding new capabilities where they are needed.
Our systems are designed to work across manufacturers, platforms, and communication technologies, allowing organizations to improve interoperability without requiring every user or department to move to the same system.
C-AT can integrate existing equipment with:
Land Mobile Radios
PTT-over-cellular applications
SATCOM and BLOS communications
Vehicle intercom systems
PPE and hazardous-environment communications
Dispatch and command systems
Headsets, cabling, and specialized accessories
When the requirement goes beyond a standard configuration, C-AT can engineer the connections needed to make the system work as part of the broader operation.
C-AT systems can be configured for local, closed-site, remote, and beyond-line-of-sight communications, giving organizations options when internet, cellular, or conventional radio infrastructure is unavailable, restricted, or not appropriate for the operation.
C-AT approaches communications from the requirement outward. We look at the people, equipment, environment, and systems that need to communicate, then determine how to connect them.
Technology-agnostic integration: Connect radios, networks, headsets, applications, vehicles, and communication technologies from different manufacturers.
Use existing equipment: Add interoperability and new capabilities without automatically replacing fielded radios and systems.
Standard systems with custom engineering: Start with ICRI, ComForce, or WIS and configure, integrate, or engineer beyond the standard system when the requirement calls for it.
One broader communications architecture: Connect radio users, vehicle crews, personnel in PPE, command teams, SATCOM, cellular/PTT platforms, and other supported systems.
Built around the operation: Systems can be configured for mobile, portable, fixed-facility, secure-site, and specialized communication requirements.
C-AT gives organizations more freedom to build communications around the operation instead of building the operation around a single communications platform.
Communication equipment has to work for the person using it and for the organization responsible for deploying and supporting it.
C-AT designs systems with both in mind:
For operators: straightforward controls, glove-accessible options, and configurations built around how personnel actually work
For program managers: scalable systems that can be configured around operational, security, and equipment requirements
For integrators and OEMs: flexible interfaces, cabling, radio integration, and custom engineering support
For the organization: the ability to incorporate existing equipment, add new capabilities, and expand the system as requirements change
From a single operational need to a larger communications architecture, C-AT works with customers to configure the system around the people, equipment, and environment it has to support.
