From Port to Open Sea, REDCOM Sigma Keeps You Connected
Interoperable Comms, Regardless of Endpoint
From the P25 radios commonly used by public safety agencies to cell phones, desk phones, and other endpoints, Sigma can connect them all. Integrating REDCOM Sigma into your organization or port’s communication plan enables unified communications even when outside agencies use disparate radios and other communications tech.
When operations are on the line, REDCOM Sigma keeps you connected — from the harbor to the high seas, and everywhere in between.


Crossband Radio Networks With Sigma XRI
The REDCOM Sigma XRI is a Small-Form-Factor Command and Control (C2) platform featuring voice, video, chat, and radio interoperability, along with an integrated console. It is more than just a basic radio gateway. Users can bridge radio nets, satellite communications, LTE networks, and wired or wireless IP in any form.
Communicate Across Agencies
Instantly link the disparate radios, softphones, and other communication endpoints that different organizations use.
IP-Based PTT Voice Integration
REDCOM Sigma XRI enables seamless interoperability with unicast and multicast RTP-capable radios and PTT apps.
Secure, Reliable, and Built for the Open Water
Control and Organize All Maritime Comms From a Single Device
Maritime operations require a high level of communication and coordination. REDCOM Sigma® C2 Console is a powerful app that provides operators with a single pane of glass to monitor and control all communications, including both SIP and radio endpoints.
Operators can create persistent and ad-hoc channels, keeping comms organized. New users can be trained on Sigma in hours or days, not weeks — perfect for maritime organizations looking to quickly bring employees up to speed.
