Description
Global Communications Through the Iridium Network
The LT-3100 operates on the Iridium satellite network, providing truly global coverage, including remote land areas, mountain regions, deserts, forests, and polar locations. Unlike terrestrial communication systems that depend on cellular infrastructure, the LT-3100 enables voice calls, SMS messaging, circuit-switched data, and SBD services from virtually anywhere.
Whether installed in a command vehicle, remote operations center, or field office, the system provides dependable communications for organizations operating beyond the reach of traditional networks.
Designed for Permanent Installations
The LT-3100 consists of three primary components: the LT-3110 Control Unit, LT-3120 Handset, and LT-3130 Antenna Unit. This modular design allows the antenna to be mounted outdoors while the control unit and handset remain safely installed inside a vehicle or facility.
A single coaxial cable of up to 500 meters (1,640 feet) connects the antenna to the control unit, providing exceptional installation flexibility for large vehicles, industrial facilities, and remote infrastructure.
Built for Demanding Operations
Engineered for continuous professional use, the LT-3100 is designed to perform reliably in challenging environmental conditions. The outdoor antenna features an IP67-rated enclosure for protection against dust and water, while the system's wide operating temperature range supports year-round deployment in harsh climates.
Integrated GNSS provides accurate positioning for fleet management, tracking, and operational awareness, while Bluetooth support enables convenient wireless connectivity with compatible devices.
Flexible for Professional Applications
The LT-3100 is designed for organizations that depend on reliable satellite communications during daily operations or emergency situations.
Typical applications include:
- Emergency response and public safety
- Government communications
- Utility and infrastructure operations
- Mining and energy sites
- Transportation and fleet management
- Remote industrial facilities
Built for Reliable Everyday Communications
The LT-3100 combines dependable satellite voice services with practical installation flexibility and professional-grade hardware. Support for analog telephone integration, GNSS positioning, Bluetooth connectivity, and remote configuration allows it to integrate easily into existing communications systems while providing reliable access to the global Iridium network.
