The TRB256 is an industrial 4G LTE NB-IoT gateway designed to be applied to a broad range of IoT solutions. The device is equipped with multiple WAN interfaces, such as I/Os, RS232, RS485, and an Ethernet port, additionally boasting dual SIM functionality for continuous connectivity. This industrial-grade gateway also supports the 450 MHz frequency band, offering superior LTE signal penetration compared to standard frequencies, making it an optimal choice for a diverse range of M2M applications.
4G LTE Cat M1 up to 588 DL/ 1119 UL kbps, Cat NB2 up to 127 DL/158.5 UL kbps, Cat NB1 up to 32 DL/70 UL kbps (simultaneous operation of cellular and GNSS connectivity is not supported)
