ICRI Cross-Band LMR and SATCOM Voice Architecture

PTToC, MESH, P25, LMR, Trunked, and mobile phone audio can all be connected at the edge through the ICRI. The ICRI converts the audio into IP, and passes it through a VPN router. From there, it is transported over available networks such as Starlink, 4G/5G and delivered to secondary endpoints including remote ICRI units, dispatch consoles, VoIP phones, PTT applications, VoIP apps

 

This approach allows disparate radio technologies and devices to operate as a single, coordinated voice network without relying on fixed towers or centralized dispatch infrastructure.

Operational Benefits of Satellite-Enabled LMR

 

A hurricane wipes out infrastructure. A wildfire pushes responders beyond coverage. A bridge collapse isolates teams from command. When terrestrial radio systems fail or reach their limits, continuity of voice communication becomes the mission.

 

ICRI-enabled satellite interoperability extends Land Mobile Radio (LMR) beyond fixed infrastructure by bridging trusted radio systems to satellite networks when and where they are needed. The result is resilient, controlled voice communications that continue to function even when towers, dispatch centers, or backhaul networks are unavailable.

 

The mSatLink ICRI, iSatLink ICRI, and sSatLink ICRI connect LMR users to satellite services including MSAT-G2, Iridium, and Starlink, preserving familiar radio workflows while expanding operational reach. Teams maintain voice coordination across jurisdictions, terrain, and infrastructure gaps without reprogramming radios or relying on fragile network dependencies.

 

  • mSatLink ICRI integrates with MSAT-G2 and Iridium to maintain LMR voice continuity in infrastructure-compromised environments.

 

  • iSatLink ICRI provides global Iridium connectivity, extending LMR communications for remote and mobile operations.

 

  • sSatLink ICRI leverages Starlink’s high-throughput, low-latency satellite network to support extended LMR voice coordination when broadband transport is required.

 

This architecture ensures that LMR systems do not operate in isolation. Voice traffic can be extended, bridged, and managed across satellite paths while remaining compatible with broader interoperability solutions used in vehicles, mobile command posts, and field operations.

 

When everything else goes down, this is the connection that keeps working.

 

ICRI preserves command continuity by extending LMR voice communications beyond fixed boundaries so responders stay coordinated, informed, and in control, even when the operating environment changes faster than the infrastructure can recover.

DISASTER RELIEF

ICRI enables disparate radio systems and devices to operate as a single, coordinated voice network by bridging audio at the edge and transporting it over available IP networks.

PTToC, MESH, P25, LMR, trunked radio systems, and mobile phone audio are connected locally through the ICRI. The ICRI converts analog and digital voice into IP and securely passes it through a VPN router.

From there, voice traffic is transported over available networks including SATCOM solutions such as Starlink, as well as 4G/5G cellular, and delivered to secondary endpoints including:

• Remote ICRI units  
• Dispatch and command consoles  
• VoIP desk phones  
• PTT and VoIP applications  
• Remote field teams and mobile command posts  

This architecture allows agencies to extend voice communications beyond fixed towers, geographic boundaries, or centralized dispatch centers. Multiple radio technologies and devices operate as one unified voice network, even when infrastructure is degraded or unavailable.

Built for responders, not radio specialists.

No software, no logins, no menus.

Plug-and-play operation lets teams focus on mission, not configuration.

Trained operators and non-technical personnel can deploy and use within minutes.

 

In Multi-agency scenarios, interoperability plans often break down not because of technical capability but because systems cannot connect when infrastructure fails.

 

The ICRI’s rugged, portable design ensures responders remain coordinated under pressure - whether in remote disaster zones, joint defense missions, or mutual aid responses.

Security and encryption controls remain with your radios.

The ICRI links radios for interoperability while preserving existing cryptographic protections.

All audio is routed only when a handset or speaker is connected, and physical controls prevent unintentional bridging.

Frequently Asked Questions

Does this work with encrypted radios?

Yes. The ICRI supports interoperability between encrypted radios while preserving existing COMSEC controls. Encryption and cryptographic management remain fully owned by the radios and approved systems. The ICRI does not encrypt, decrypt, store, or process data traffic. It routes audio only, allowing agencies to maintain operational security while enabling controlled coordination between systems.

Contact Us
How fast can this be deployed?

The system is designed for rapid deployment in time-compressed environments. Because it does not require network infrastructure, software configuration, or radio reprogramming, it can be set up and operational within minutes once radios are connected. This makes it well suited for disaster response, contingency operations, and situations where infrastructure is unavailable or compromised.

Contact Us
What training is required?

Minimal training is required. The ICRI is intentionally designed for non-radio personnel as well as communications specialists. Operation is based on physical controls and clear indicators rather than menus or software interfaces. Most users become operationally effective after a short familiarization, which helps reduce training burden, sustainment costs, and reliance on a single communications expert.

To support continuity of operations and personnel rotation, structured training options are available, including initial familiarization and recurring refresh cycles conducted annually or semiannually based on agency requirements.

Contact Us
Can this integrate with existing SOCOM or state communication plans?

Yes. The ICRI is routinely used in environments where agencies operate under established DoD, SOCOM, state, and local communication plans. Because it does not change how radios operate or manage encryption, it integrates cleanly into existing interoperability, COOP, and PACE frameworks. Agencies retain full control over talk group selection and coordination while preserving command structure and policy boundaries.

Contact Us
Can the ICRI integrate with C-AT ComForce Vehicle and the Hands Free Wireless Intercom Systems (WIS)?

Yes. The ICRI is designed to integrate with other C-AT communication systems, allowing voice traffic from radios and satellite links to be extended into vehicle and dismounted communication environments.

At a high level, the ICRI serves as the interoperability core, while ComForce and the Wireless Intercom System provide mission-specific user interfaces.
