Proscend’s Industrial Cellular IoT Gateway, offering high security and performance, is designed to collect data from industrial automation devices such as PLCs, sensors, servos, HVAC systems, and water pumps. These field data are encrypted and transmitted to remote locations via VPN tunnels over 4G/3G cellular networks. Hence, administrators at a central control center can build their own HTTPS and/or MQTT servers to process and analyze data from a large number of Industrial Cellular IoT gateways, and remotely control the industrial automation devices behind one or more designated Proscend’s gateways.
