Clearer Comms. Faster Response. Safer Outcomes.

When it comes to public safety radio communications, first responders from various departments and jurisdictions must be able to communicate with each other seamlessly. If not, lives can be lost.

REDCOM has a long history of creating user-friendly communications technology that takes interoperability to the next level. We’ve applied our extensive knowledge of the communication requirements for joint operations, gained from our partnerships with the military, to the demands of public safety and emergency services teams.

How Does REDCOM Sigma Compare to Competitors?

Infinite Interoperability When it Matters Most

Police, firefighters, and emergency medical staff know better than anyone how critical communication is. Now, more than ever, public safety officials are required to work together with different agencies in responding to incidents, which can present interoperability challenges.

A single emergency event might involve multiple departments with entirely different radios and endpoints, preventing these agencies from communicating with each other. REDCOM Sigma addresses this issue without requiring the replacement of existing technology.

Discover the REDCOM Difference

Interoperability with P25 Radios for Police & Fire

REDCOM Sigma ensures seamless interoperability with Project 25 (P25) radios—a digital radio standard widely adopted by public safety agencies. By integrating Sigma with P25-equipped systems, REDCOM enables unified communications even when agencies use different radio technologies or operating environments are compromised .

Faster, Clearer Coordination

Officers and firefighters—regardless of agency—can instantly communicate without cumbersome workarounds or radio swaps.

Simpler Multi-Agency Response

In joint operations, P25 and legacy radio users can communicate with other endpoints, boosting situational awareness and efficiency.

Future-Ready Infrastructure

With support for emerging IP-radio formats, Sigma prepares agencies for next-generation comms technologies.

REDCOM Sigma XRI

Bridge Radio Nets With Any Endpoint

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.

IP-Based PTT Voice Integration

REDCOM Sigma XRI enables seamless interoperability with unicast and multicast RTP-capable radios and PTT apps.

Immediate Multi-Agency Comms

Instantly link the radios, softphones, and other communication endpoints that disparate public safety organizations use.

Easy to Deploy & Learn

New users can be trained on Sigma in hours or days, not weeks. Confidently implement, operate, and maintain core C2 functions.

Low Size, Weight, & Power (SWaP)

Sigma XRI was built to MIL-STD specs. It weighs only 2.6 pounds, is resilient to hard shutdowns, and powers up in less than two minutes.

Sigma Client for ATAK

No Radio? No Problem.

REDCOM Sigma Client for ATAK is a voice plug-in that enables instantaneous push-to-talk (PTT) communication across SIP and RF endpoints, including radios, MANETs, IP phones, and softphones. Sigma Client works with existing tactical PTT and headset hardware and enables comms via pre-configured or ad-hoc channels which emulate traditional radio nets.

Joint Coordination Has Never Been Easier

Instantly link the radios, softphones, and other communication endpoints that disparate public safety organizations use—without replacing existing gear.

Reduce Dependency on Radios

Radios are expensive and can strain your already tight budget. Our ATAK plugin is a perfect alternative that allows you to save money while staying connected. The result is improved communications, enhanced interoperability, quicker response times, lighter loadouts, and more money for other expenditures.

Pre-Configured or Ad-hoc Channels

Sigma Client provides users with ad-hoc and preconfigured channels to set up talk groups quickly and efficiently before and during an operation.

Trusted by the Los Angeles Fire Department for Over 35 Years

The Los Angeles Fire Department—one of the nation’s largest fire agencies with 106 fire stations, over 3,700 personnel, and nearly 500,000 annual incident responses—has relied on REDCOM for mission-critical communications equipment since the early 1990s. In 2019, LAFD began a multi-year modernization effort to upgrade from analog to all‑IP fire station alerting, built around a strategic, two‑phase approach led by REDCOM.
