With advanced authentication methods and support for both IPv4 and IPv6, it ensures secure and efficient network performance.

## Long description

The Teltonika TRB256 is an industrial 4G LTE NB‑IoT gateway designed for a wide range of IoT and M2M solutions. It provides reliable Ethernet connectivity at 10/100 Mbit/s, an IP30 aluminum enclosure, external R‑SMA antenna connector and multiple WAN interfaces including digital I/Os, RS232, RS485 and one Ethernet port. Dual SIM support and compatibility with the 450 MHz band improve availability and LTE penetration in challenging environments, making the device suitable for remote and industrial deployments.
Advantages
The TRB256 combines industrial‑grade hardware with flexible connectivity: multiple serial interfaces (RS232, RS485), digital I/Os, Ethernet and dual SIM for failover or multi‑operator support. Support for the 450 MHz LTE band ensures better signal penetration in buildings and remote areas compared with standard LTE frequencies. The unit’s metal IP30 enclosure and external antenna connection increase durability and installation options, while management via WEB UI, SSH and MQTT enables integration into existing monitoring and control systems.
Suitable for
Remote telemetry and sensor data collection
M2M applications in industrial and utility environments
Vehicle or equipment connectivity requiring reliable LTE backup
Locations with poor high‑frequency LTE coverage where 450 MHz is beneficial

How to use
Install the TRB256 on a DIN rail or suitable mounting surface and connect the external antenna to the R‑SMA connector. Insert one or two active SIM cards according to the desired failover or multi‑operator configuration. Connect the Ethernet cable to the RJ‑45 port and wire any required serial devices to the RS232/RS485 terminals or configure digital I/Os as needed. Access the device management interfaces via WEB UI or SSH to configure network settings, authentication and MQTT or other protocol parameters before deploying to the field.
Usage recommendations
For reliable operation in industrial installations, use high‑quality external antennas positioned for optimal reception, enable dual SIM failover where continuous connectivity is critical, and keep firmware up to date. When deploying in areas with limited high‑frequency LTE coverage, verify operator support for the 450 MHz band to benefit from improved penetration.
