Teltonika TRB143 — Industrial 4G (LTE) M-Bus Gateway for IoT and Smart Metering

The Teltonika TRB143 is a compact industrial 4G LTE gateway with multiple interfaces, designed for reliable mobile connectivity in IoT applications, industrial automation, and transport systems where resistance to harsh environmental conditions and advanced data security are essential operational requirements. It is deployed in factories, vehicles, and isolated locations where stable 4G LTE connectivity and centralised remote management form the backbone of industrial communications infrastructure.

Multiple ports provide integration flexibility with a wide range of industrial equipment and IoT devices without additional adapters or external modules. 4G LTE connectivity delivers high transfer speeds and connection stability for critical applications with continuous data transmission requirements — process monitoring, telemetry, and remote control of distributed equipment at locations without fixed network access.

Advanced security features — firewall and support for multiple simultaneous VPNs — protect transmitted data in industrial networks with multiple access points and cyber threat exposure. The ruggedised compact enclosure provides the mechanical resistance required for use in industrial environments, vehicles, and transport systems where equipment is subject to vibration and thermal variation. Remote management via the Teltonika RMS platform enables centralised monitoring and configuration without physical on-site interventions.

Recommended for industrial automation and IoT applications in factories and isolated locations with simultaneous robustness and reliable 4G connectivity requirements, transport systems and vehicles where compact form factor and vibration resistance are essential selection criteria, distributed infrastructures where remote management and VPN security reduce operational costs and cyber risks, and any critical industrial deployment where network reliability and data protection cannot be compromised.
