E4A's quad-band industrial IoT gateway for sensor monitoring

Industrial IoT gateway with LTE, LoRa, and Wi-Fi connectivity options

GTW-200 rugged industrial IoT gateway mounted on DIN rail

Quad-Band Gateway

GTW-200

Category: Gateways

E4A's Quad Band Gateway is designed to meet the increasing demand for LTE connectivity in rural industrial sites, such as power generation utilities, mining, forestry, construction, and many others.
Many of these remote operations and facilities do not have corporate Local Area Network (LAN) coverage, which can hinder communication with remote wireless sensors.
By enabling LTE connectivity, E4A’s gateway ensures reliable communication between sensors at these sites and the central corporate network, facilitating seamless data transmission to the central repository.
