Dominate the fight with Sigma PTT

Outthink. Outmaneuver. Outcommunicate.

Push-to-talk solutions currently employed within the DoD are complex, expensive, and challenging to maintain. The warfighter at the tip of the spear requires a powerful but easy-to-use solution that enhances current capabilities while minimizing cognitive overload.

REDCOM technology increases the warfighter’s effectiveness and security posture while reducing lifecycle, training, and maintenance costs. We have ATOs with the U.S. Army and U.S. Air Force, where our Sigma solutions are already delivering a communications advantage at the tactical edge.

Home / Modernizing PTT Communications with Sigma

Gain a tactical advantage with REDCOM PTT technology

Intuitive and simple GUI interface

Streamlines workflows and minimizes ‘button presses’

Perpetual licensing model

REDCOM software can still be used without annual maintenance agreements

Integrated RoIP

Reduces complexity and cost by simplifying network architecture

Interoperability

Mitigate obsolescence with hardware and software that are fully interoperable with existing deployed equipment

Enhanced mobility

REDCOM solutions are incredibly easy to use, setup, configure, deploy, and are resilient to hard shutdowns

All-in-one solution

Voice, video, chat, audio and video conferencing, transcoding, secure soft clients, console, and TSM integration in one low-SWaP package

Sigma Client

Voice, Video, Victory

PTT app is available on ATAK, Android, and Windows
Embedded soft PTT button on screen for instant communications
Converges half-duplex and full-duplex comms platforms
Optimized for half-duplex communications common at tactical echelons
Integrated with tactical PTT and headset hardware
Enables in-band DTMF signaling through a trunk, adding robustness to call scenarios
Spatial audio: hear simultaneous voice convesations by assigning channels to different positions on a headset (left front, left rear, right front, or right rear).

Sigma XRI

Bridge every radio gap, from legacy analog to next-gen MANETs

Native integration with radios from Silvus Technologies, Persistent Systems, DTC, and Thales via generic RTP radio lines

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.

Sigma C2 Console

Command all comms from one screen

Deploy your way: cloud, hypervisor, or hybrid

Sigma delivers more capable tactical voice communications while reducing network complexity, cutting costs, and improving operational efficiency. Deploy Sigma in the configuration that fits your environment:

Price tags lie. Lifecycle costs tell the truth.

The upfront price rarely reflects the true cost of technology. Hidden lifecycle expenses add up quickly. REDCOM Sigma is built to minimize total cost of ownership through simplicity, efficiency, and flexible pricing.
