The TRB256 is equipped with a variety of WAN interfaces, such as input/output (I/O), RS232, RS485 and an Ethernet port. With these interfaces, the device can be integrated into a wide variety of systems and devices, offering flexibility and compatibility at the highest level.
One of the key strengths of the TRB256 LTE M1/NB-IoT Gateway is its dual-SIM function, which ensures a continuous and reliable connection. With this feature, the router automatically switches between SIM cards in case of signal loss, ensuring uninterrupted communication at all times.
A unique feature of the TRB256 is its support for the 450 MHz frequency band. This frequency enables better LTE signal penetration compared to standard frequencies, making this router ideal for M2M (machine-to-machine) applications. As a result, the TRB256 provides reliable and stable connections even in the most demanding conditions.
