Seamless interoperability with IP and analog tactical radios

Fully compatible with the most popular IP radios from L3Harris, Silvus Technologies, TrellisWare, and Persistent Systems

  • Connects disparate radio systems to each other, regardless of radio network, endpoint, or frequency used.
  • Native interoperability with MANET networks, extending voice talk groups by linking them with other analog radios and the rest of the C2 network.
  • Radio Over IP (RoIP) allows radio users to communicate directly with other users on any SIP end device (e.g., SATCOM, softphones, VoIP phones).
  • Provides continuity of communications within contested areas without replacing their entire system or installing expensive relay systems.
  • Enables interoperability between Joint and Coalition forces with disparate devices and long-range communication in DIL environments.

Flexible Deployment Without Sacrificing Operational Capacity

At REDCOM, we strive to provide communication solutions for every situation, which is why we designed Sigma to reduce costs, simplify networks, increase operational efficiency while maintaining a very low SWaP architecture. Sigma can be deployed in various ways to meet any criteria:

  1. Software-only on your compute platform
  2. Sigma XRI-400, REDCOM’s standalone C2 and RoIP platform
  3. A module for Klas or PacStar systems

Regardless of the deployment method, Sigma will greatly bolster your PTT communication capabilities without requiring a complete rip-and-replace of existing assets.
