The Teltonika TRB141 gateway connects industrial devices over 4G LTE Cat 1, 3G and 2G networks and supports remote monitoring and control. It provides digital and analog inputs and outputs, as well as 1-Wire sensor support. The RutOS operating system is based on OpenWrt and includes a firewall, VPN and firmware updates over the internet (FOTA).

The device supports IPv4/IPv6, TCP, UDP, ICMP, HTTP/HTTPS, MQTT, SNMP and SSL/TLS protocols, as well as VPN via OpenVPN and IPsec. It is compatible with the Teltonika Remote Management System (RMS) and features SMS functionality, network diagnostic tools, and monitoring for RSSI, SINR, RSRP and RSRQ.
