The Bivocom TW810 series LTE-M/NB-IoT modems are designed for applications require better signal and coverage, lower consumption serial modem for sending their field serial data to remote server via LTE CAT M1 and NB-IoT network, applications such as smart building, HVAC, underground pipeline monitor, or moving assets management.

The Bivocom TW810 is a low cost and bandwidth solution to replace legacy GPRS/GSM serial modem, as GPRS/GSM network has been shut down in some regions by carriers, and more carriers have scheduled to shut down their GPRS/GSM network in the coming years; so the Bivocom TW810 is a great fit and ideal solution for these applications.
The TW810 has a built-in independent MCU chipset, multi-layer software detection and hardware protection mechanism to ensure reliability and stability, and RS-232, RS-485 ports to easily connect to serial port sensors, PLCs, IPCs and controllers.  It supports transparent data transmission, which helps you to seamlessly transfer the data under MQTT*, Modbus RTU, TCP/UDP protocol to your remote server. It also supports up to 5 sync data center, which enables you to receive the same data in different location and backup your data.
The Bivocom TW810 comes with a powerful and easy to use configuration tool that allows you to choose different type of cellular network and protocols for your specific needs.
