# WT410- LTE-4GLITE

### **Wiman 4G -LITE Gateway Series**

The **Wiman LITE 4G Gateway** is a compact and cost-effective industrial IoT device designed exclusively for **4G LTE connectivity with 2G fallback**. It provides reliable wireless communication for remote installations where only cellular network coverage is available.

The gateway acquires data from **Modbus RTU (RS485) slave devices**, including energy meters, PLCs, sensors, controllers, and all standard Modbus-compliant devices, along with built-in I/O support. It securely transmits data to centralized servers or cloud platforms using **TCP, HTTP, or MQTT protocols**, with optional SSL encryption for enhanced security. The device supports bidirectional communication, enabling both data transmission and remote command execution.

To ensure data integrity, the gateway features an inbuilt intelligent data logger. During network or server interruptions, critical data is stored locally and automatically synchronized once the connection is restored—preventing packet loss and ensuring continuous reporting.

Remote configuration and firmware updates are supported via **SMS, TCP Remote Mode, FTP, and IP commands**, reducing the need for on-site service and simplifying deployment and maintenance.

### 📌 **Limitless Applications (GSM / 4G Use-Cases)**

These are applications where **cellular connectivity** is important (remote or unstable networks):

* Smart Meter Reading
* Power Monitoring & Control
* PLC & Industrial Automation (Industry 4.0)
* Temperature & Alert Systems
* Pump & Flow Monitoring
* SCADA, Solar & Windmill Monitoring
* ATM, Cold Storage, Home Automation

Why GSM matters here:\
These sites are often **far from LAN/Wi-Fi**, so 4G is the only reliable link.
