Achieve Unmatched Precision and Advanced Security
When all else fails, emergency communications needs to be the last service standing. Our land mobile radio (LMR) solutions provide reliable and secure communications by using advanced, flexible, and rugged hardware and software. Our LMR solutions:
- Enhance audio clarity using simulcast-synchronized satellite clocks, reducing downtime and leveraging GPS for precise timing.
- Improve system security against cyber attacks and broadcast storms using resilient, deny-by-default operational technology (OT) software-defined networking (SDN).
- Strengthen your system reliability with equipment designed and built in the United States, capable of withstanding environmental extremes from –40° to +185°F (–40° to +85°C).
- Allow you to monitor your entire system remotely on a single HMI screen, supporting maintenance and network management.
We back our solutions with a ten-year warranty, no-cost repair service, and complimentary around-the-clock support based in the United States.
Protecting essential communications with an advanced LMR system provides high-quality audio and allows first responders and dispatchers to stay focused on what matters most: saving lives.

Customer Highlight: WCEM Enhances Emergency Communications
“At the end of the day, we need three fundamental things for our infrastructure. We need reliable network security. We need to know the health and condition of the radios out there in the world, and we need precise timing.”
—Steve Krigbaum, a 50-year veteran in the emergency communications sector
Improve the Quality and Reliability of Your Emergency Communications Audio

Designed for critical infrastructure networks with the highest standards in synchronization, the SEL-2488 Satellite-Synchronized Network Clock is accurate, reliable, and secure. Within minutes of plugging into an LMR system, the clock locks to GPS signals, immediately delivering precise time to repeater sites. The result is clear audio from dispatchers that minimizes the risk of communication delays or errors to first responders.
Reliability in Action: SEL Collaborates to Optimize Area Emergency Response
“What we’re talking about here is boots on the ground, public safety, life safety, not only for our residents who are having an emergency but for our first responders to help keep them safe. And to have that clear communication with the whole system and for SEL to come up with a solution, when we’re talking about life safety, public safety issues, this is amazing.”
