REDCOM Sigma XRI

Small form factor C2 comms platform with an integrated radio gateway

Product Overview

Sigma XRI is a low-SWaP C2 comms and radio interop platform that bridges the gap between disparate radio systems used by military units, government agencies, and public safety organizations. By leveraging existing radio assets, Sigma XRI enables these organizations to seamlessly connect to each other, regardless of radio network, endpoint, or frequency used.

Because Sigma XRI is a full-featured C2 platform, radio users can communicate directly with users on any SIP endpoint and can be controlled and patched together on-the-fly via the REDCOM Sigma C2 Console app.

XRI Key Benefits

One platform for controlling all IP and RF comms
Interoperable with unicast and multicast RTP-capable radios and PTT apps
Reduces lifecycle costs and overall network footprint
Reduces training time and improves operational tempo
Reduces the complexity of installing & maintaining comms
Five models available to suit every kind of tactical deployment

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 hardware, warfighters can instantly bridge the gap between disparate radio networks, endpoints, or frequencies, allowing for seamless communications between Joint and Coalition forces.

Sigma XRI 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 nets can even be bridged with other radio nets and TSM talk groups on a TSM mesh network.

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, SATCOM, and TSM.
Configurable PTT signaling modes per port and per caller.
Supports patches, dialed calls, and independent monitoring.

IP-based PTT voice integration

REDCOM Sigma XRI enables seamless interoperability with unicast and multicast RTP-capable radios and PTT apps — including radios from Silvus Technologies, Persistent Systems, DTC, and Thales.

Simultaneous access to multiple talk groups on a single radio network via individual Sigma radio lines — such as a TSM RF mesh network.
IP-connected radio nets connect to the XRI via ethernet and do not use up any of the 4 analog radio ports.
IP-connected radio nets and talk groups can be bridged together (as a channel, patch, or conference) with other IP-connected radio nets, analog-connected radio nets, SIP endpoints, and a console operator.

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 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.

Resilient & future proof design

Designed for shoot, move, communicate operations, Sigma XRI was developed to be robust, resilient, and future-proof. The flexible nature of REDCOM Sigma XRI 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 less than two minutes.
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.

Improves tooth-to-tail ratio 

REDCOM Sigma XRI 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 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 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 supports IP phones, radios, and clients on ATAK, Android™ & Windows®.

Brilliance in the Basics

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

XRI Configurations

Sigma XRI is available in five configurations. All XRIs are powered by REDCOM’s flagship Sigma C2 software. In the XRI-400, a built-in compute platform hosts the preinstalled Sigma software. In the other four XRI models, Sigma software runs on a connected compute platform.

Sigma XRI-400

Sigma XRI-400 is REDCOM’s flagship all-in-one C2 and radio interop platform.

With Sigma software running on the integrated compute module, the XRI-400 gives users a single-box solution for connecting all IP and RF endpoints on the C2 network.

XRI-400 delivers voice, video, chat, radio crossbanding, and an integrated C2 console all in a single low-SWaP 2.6 lb box.

XRI-400 features 4 built-in analog radio ports, which can be expanded to 8 by adding the XRI-M4R module.

Sigma XRI-M4R

Sigma XRI-M4R adds radio interoperability to existing tactical installations, or can double the XRI-400’s radio ports from 4 to 8.

Sigma XRI-PCI

A 4-port radio gateway card that installs into an available PCIe expansion slot on a PC or server.

Sigma XRI-M4K

A module for the Klas Voyager platform, bringing all the power of REDCOM Sigma, C2 interoperability, and radio crossbanding to existing Voyager systems.

PacStar 421 with XRI

A module for PacStar systems from Curtiss-Wright. Delivers all the power of Sigma XRI in a PacStar 400-series tactical computing module.
