Legacy RS485 & RS232 Telemetry
Modernize aging infrastructure instantly. Connect legacy industrial PLCs, RTUs, and sensors via RS232/RS485 to the modem, transmitting raw serial data transparently over public 4G LTE networks to centralized cloud servers without altering original equipment protocols.
Industrial Modernization → Real-Time Fleet & Asset Tracking
Maintain absolute visibility over high-value mobile assets. The GPS-enabled modem provides high-accuracy geographic positioning while simultaneously transmitting onboard vehicle telemetry, making it perfect for logistics, railway, and heavy equipment tracking.
Asset Tracking Solutions → Low-Power Environmental Monitoring
Deploy monitoring stations in remote, off-grid locations powered only by small solar panels or batteries. The modem's ultra-low power sleep modes and configurable SMS/Data trigger wake-ups ensure years of reliable environmental data collection.
Environmental Monitoring → Multi-Center SCADA Redundancy
Ensure critical utility and smart grid data is never lost. Configure the modem to duplicate and transmit incoming pulse counter and analog sensor data to up to 5 different backup servers simultaneously, providing ultimate SCADA redundancy.
SCADA Redundancy → Cost-Effective Smart Metering
Roll out massive smart city metering networks economically. Utilizing the globally optimized LTE CAT-1 standard, the modem delivers the perfect balance of necessary bandwidth (up to 10 Mbps), low latency, and highly cost-effective hardware for utility billing.
