REDCOM and Klas unite to launch advanced tactical radio interoperability for the edge

November 7, 2022

The new REDCOM Sigma XRI-M4K module brings the power of REDCOM Sigma® C2 software and radio interoperability to the highly rugged Voyager platform.

REDCOM Laboratories, Inc. and Klas announced the launch of a new tactical communications module for the Voyager platform, the REDCOM Sigma XRI-M4K.

XRI M4K tactical module for Klas Voyager Powered by REDCOM’s proven Sigma® C2 software, the Sigma XRI-M4K bridges the gap between disparate radio systems used by military units, government agencies, and public safety organizations. It provides a full spectrum of C2 comms and easy-to-use radio interoperability and crossbanding, leveraging existing radio assets and enabling these organizations to instantly connect to each other, regardless of the radio network, endpoint, or frequency used. Furthermore, the XRI-M4K module allows radio users to communicate directly with users on any SIP endpoint and can be controlled and patched together on-the-fly via the REDCOM C2 Console app.

“REDCOM and Klas are aligned to solve joint C2 challenges in current and future operational environments in a single multi-mission, multi-domain platform. Voyager and REDCOM Sigma are already C2 platforms of choice for multiple programs across the DoD,” said REDCOM Strategic Lead John Kelliher. “Communications are a mission-critical component of Command and Control. REDCOM Sigma is purpose-built to enhance interop and mobility, creating an adaptable solution to ensure critical lines of communication stay up in a DDIL environment. Integrating complementary platforms that are familiar to the warfighters will keep training and lifecycle costs low and reduce overall complexity, infrastructure, and support requirements.”

“The Voyager platform from Klas was designed to enable a diverse mission set of capabilities. The REDCOM Sigma addition adds even more capability to our ecosystem and demonstrates how central communications are to enabling success at the tactical edge. We’re excited to have REDCOM as a partner and have the XRI-M4K be part of the Voyager ecosystem,” said Chris Ericksen, Chief Revenue Officer, Klas.

Voyager is a modular and scalable range of network, compute, and radio systems designed to meet the requirements of government and public safety communicators in any operational environment. As a module for the Voyager platform, REDCOM Sigma XRI-M4K provides a full spectrum of C2 comms and radio interoperability, managed and controlled by REDCOM’s proven and easy-to-use Sigma C2 software. Up to two Sigma M4K modules can be installed in the same Voyager system, each providing four analog ports for donor radios.
