Quad-Band Gateway
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.
Gateway Features
Includes sensors for ambient temperature, humidity, and tri-axis accelerometer to monitor environmental conditions and movement.
Connectivity & Communication
Multiple connectivity options including LTE Cat 1, LoRa 900MHz, Wi-Fi, and secure communication protocols like AES 128-bit encryption over BLE and TCP/IP.
Microcontrollers & Processing
Equipped with powerful 32-bit Arm Cortex-M4F MCUs, the GTW-200 ensures efficient wireless processing and communication.
Power & Circuit Protection
Features Power over Ethernet (PoE), multi-rail power management, and robust circuit protection against over-voltage, over-current, reverse polarity, and thermal shutdown.
User Interface & Display
Offers a variety of inputs and outputs including analog and digital ports, SD card slot, SIM card slot, and is designed for flexible wall and DIN rail mounting.
Special Features
Includes an internal memory card, QR code labeling for easy identification, and the ability to monitor operational data securely.
