Introduction
The OnCell 3120-LTE-1 Series is a range of LTE Cat.1 cellular gateways built for reliable connectivity, easy maintenance, and quick deployment in diverse environments. These gateways deliver stable Serial/Ethernet-to-cellular connections and ensure optimal reliability with GuaranLink cellular auto-recovery. With MRC Quick Link Ultra, operators gain complete visibility and secure remote control over both the OnCell gateway and its connected end devices, allowing for faster troubleshooting, minimal downtime, and more reliable industrial operations. Designed for edge applications, the OnCell gateways features power-saving technology that reduces standby consumption to below 40 mW via scheduling control, making them ideal for power-constrained remote applications. Full support for serial interfaces (RS-232/ 422/485) and flexible operation modes (Real COM, Reverse Real COM, RFC 2217, TCP Server/Client, UDP), these gateways ensure seamless compatibility with serial devices. Certification for IECEx, ATEX, and CID2 certifications also make the OnCell gateways suitable for hazardous and demanding applications, such as oil and gas.
