An Industrial 4G LTE Router is a rugged, high-performance networking device designed to provide reliable wireless internet connectivity in industrial, IoT, and research environments. Unlike consumer-grade routers, it is built for harsh conditions, continuous operation, and integration with industrial automation systems.

These routers use 4G LTE cellular networks for primary or backup internet access, ensuring connectivity in remote locations where wired broadband is unavailable. They typically support WAN, LAN, and Wi-Fi interfaces, with advanced security features such as VPN, firewall, and remote device management.

Key Technical Specifications (may vary by model):

• Cellular Connectivity: 4G LTE (Cat 4/6/12), backward compatible with 3G/2G

• Network Interfaces: 1–4x Gigabit Ethernet ports, WAN/LAN configurable

• Wi-Fi Support: IEEE 802.11 b/g/n/ac (dual-band in advanced models)

• SIM Card Support: 1–2x SIM slots with automatic failover

• Operating Voltage: 9V–36V DC (wide power input for industrial use)

• Operating Temperature: -30°C to +70°C (rugged industrial design)

• Protocols: TCP/IP, DHCP, NAT, VPN (IPSec/OpenVPN/PPTP), MQTT, Modbus TCP

• Antenna Ports: External SMA connectors for LTE/Wi-Fi antennas

• Management: Web UI, CLI, SNMP, remote cloud management

Features:

• Dual-SIM failover for uninterrupted connectivity

• Industrial-grade design with DIN-rail or wall-mount options

• Secure VPN tunneling for IoT and remote monitoring

• Low latency and high reliability for M2M communication

• Wide compatibility with Arduino, Raspberry Pi, ESP32, and industrial PLCs via Ethernet or Wi-Fi

Common Use Cases:

• Remote IoT gateways in smart agriculture, energy monitoring, and logistics

• Secure connectivity for CCTV surveillance, ATMs, and kiosks

• Research projects requiring field-based wireless internet backhaul

• Industrial automation and SCADA system integration

• Backup internet for labs, startups, and R&D centers

The Industrial 4G LTE Router is highly valuable for researchers, IoT developers, and labs working on edge computing, remote monitoring, and industrial IoT applications, where uninterrupted and secure connectivity is crucial.
