For Public Safety

REDCOM Sigma® XRI-400

Small form factor C2 platform

Voice, video, chat, and radio interoperability in a low-SWaP ruggedized box for all echelons of the tactical environment.

REDCOM Sigma® XRI-400

Intelligent radio interoperability

Working with Non-Government Organizations (NGO), Joint, and/or Coalition forces presents unique challenges due to the varying signal and communications paths employed by each entity. By connecting up to four donor radios directly to the XRI-400, warfighters can instantly bridge the gap between disparate radio networks, endpoints, or frequencies, allowing for seamless communications between Joint and Coalition forces.

Sigma XRI-400 supports Radio Over IP (RoIP), allowing radio users to communicate directly with users on any SIP end device (e.g. SATCOM, softphones, VoIP phones). Radio users can even join and participate in voice conferences with users on the C2 network, including other radio nets.

  • Features 4 built-in analog audio interfaces.
  • Agnostic to radio make, model, encryption, and waveform.
  • Works with virtually any public safety or tactical radio.
  • Communicate seamlessly over multiple nets, including VHF, UHF, HF, and SATCOM.
  • Configurable PTT signaling modes per port and per caller.
  • Supports patches, dialed calls, and independent monitoring.

Resilient & future-proof design 

Designed for shoot, move, communicate operations, Sigma XRI-400 was developed to be robust, resilient, and future-proof. The flexible nature of REDCOM Sigma XRI-400 also allows for the use of various mediums in order to pass mission-critical information to any user. Communications can be fully operational within minutes, enabling expeditionary forces to secure a tactical advantage by maintaining mobility at all times.

  • Powers up in a minute.
  • Resilient to hard shutdowns.
  • Built to MIL-STD specs.
  • No rip and replace — interoperates with legacy or existing technology.
  • Enables warfighters to pivot to new C2 tech quickly and efficiently.

Support for various C2 ecosystems

Unit leaders need a command and control suite that provides consistent access to mission-critical information in order to ensure continuity of operations, maneuverability, and superiority within the battlespace. REDCOM Sigma XRI-400 is designed to maintain situational awareness for troop and equipment maneuverability in any contested environment via any means.

  • Gives the warfighter flexibility to connect to other communications infrastructure.
  • Provides warfighters with a C2 platform (voice, video, chat) for lower echelons that does not rely on higher HQ.
  • Enables stand-alone comms in DIL (disconnected, intermittent, and limited) environments.
  • Providers warfighters with the ability to interoperate in the CJADC2 (Combined Joint All Domain Command & Control) theater.

Improves tooth-to-tail ratio 

REDCOM Sigma XRI-400 enables warfighters to sustain lines of communication while on-the move without getting bogged down by gear. The small form factor and low power requirements of the Sigma XRI-400 allow it to be deployed to the tactical edge in a backpack, on a vehicle, or on aerial assets. This is particularly valuable in forward-deployed scenarios where resources are limited and soldiers must be as light as possible.

  • Solves Coalition and Joint interoperability challenges — connecting radios to Sigma XRI-400 reduces the need for liaison officers.
  • Small and light enough to be mounted in a vehicle, pack, or hand-carried
  • Flexible and scalable — a single XRI-400 supports IP phones, radios, Android™ & Windows® clients.

Powered by REDCOM Sigma®

The REDCOM XRI-400 is powered by REDCOM Sigma®, the C2 platform of choice for multiple programs within the United States Army PEO C3T.

  • Admin platform built for today’s warfighter
  • Built-in conferencing engine and web-based conference manager for joining IP phones and radios.
  • Lightweight selectable video conferencing is ideal for chaotic, congested, or contested environments
  • Evaluated for Cybersecurity (CS) and Interoperability (IO) by JITC and on the DoDIN Approved Products List.

Brilliance in the Basics

Whether you’re in a network operations center or at the tactical edge, technology must be easy to use. The XRI-400 is powered by REDCOM’s proven Sigma software platform, which features a user interface sintuitive and easy to operate that new users can be trained and up to speed in minutes or hours — not days or weeks.

  • Reduces lifecycle costs and overall network footprint
  • Reduces complexity required to install, operate, and maintain comms
  • Reduces the need for IT experts or field service reps
