TRB255 – Industrial cellular LTE CAT M1 / NB-IOT / EGPRS Gateway

TRB255 is an Industrial Cellular Gateway with multiple LPWAN connectivity options. This gateway is very flexible, because it is equipped with Ethernet, Serial (RS232 + RS485) interfaces and multiple Inputs/Outputs. It features NB-IoT, LTE Cat-M1 and is backwards compatible to EGPRS (2G).

Because of multiple cellular connectivity options, it offers cost-efficient and scalable way to upgrade a large amount of legacy infrastructure or implement new long-term M2M connectivity projects. Finally, location positioning technology (GNSS) and Dual-SIM functionality along with compatibility with Teltonika Remote Management system will make sure that your infrastructure is not only reliably connected, but also easy to monitor and control.
