REDCOM Sigma® XRI-400 is a small form factor C2 platform designed for all echelons of the tactical environment. Sigma XRI-400 delivers voice, video, chat, and radio interoperability in a single ruggedized, low-SWaP box. Sigma XRI-400 bridges the gap between disparate radio systems used by military units, government agencies, and public safety organizations.

By leveraging existing radio assets, Sigma XRI-400 enables these organizations to seamlessly connect to each other, regardless of radio network, endpoint, or frequency used. Because Sigma XRI-400 is a full-featured C2 platform, radio users can communicate directly with users on any SIP end device, and can participate in the same voice conferences.
