Cybertel Introduces Next-Gen. Upgraded Mission-Critical Communications Device

As 450MHz LTE networks continue to evolve into a backbone layer for national public safety, utilities, transportation and critical infrastructure operations, the need for resilient hybrid devices has become increasingly clear. Cybertel is addressing this need with its upgraded LM75 Mission Critical Device, engineered to support 450MHz LTE (Bands 31 and 72) and DMR Direct Mode Operation (400–470MHz) simultaneously through a single external antenna. This architecture delivers a unified communication experience that tightly couples broadband MCX performance with the reliability of conventional DMR.

For operators preparing nationwide broadband transitions or building resilient private networks, the LM75 offers a strategic bridge—ensuring uninterrupted communication even when LTE coverage is weak or unavailable.

Dual-Mode Architecture: A Strategic Advantage for 450MHz Operators 

The upgraded LM75 is designed around a dual-mode concept that intelligently combines 450MHz LTE services with local DMR DMO capability. This ensures that users maintain service continuity across wide-area LTE zones while retaining direct device-to-device communication in LTE fringe areas or full outages.

A single extended external antenna handles both frequency domains—450MHz LTE and 400–470MHz DMR—simplifying device design, improving RF performance, and ensuring operational consistency across networks.

A Strategic Platform for Hybrid MCX + DMR Environments 

The new LM75 demonstrates how 450MHz LTE and DMR DMO can coexist within a single rugged device to deliver unmatched operational resilience. For agencies and industries transitioning toward MCX-based broadband while maintaining dependable narrowband fallback, the LM75 is positioned as a crucial enabling platform—one that aligns with both present operational requirements and future 3GPP-based architectures.
