WR100LEU Queclink Industrial 4G Router

Core Purpose

WR100LEU is an industrial LTE CPE designed to provide stable cellular connectivity for fixed and mobile IoT deployments. It acts as a communication bridge between field devices and central systems. With LTE Cat 4 connectivity up to 150 Mbps, it supports data-intensive applications that require consistent network access. The device can also be installed in vehicles and used alongside tracking products to create a reliable mobile communication environment.

Connectivity and Communication

WR100LEU supports 4G LTE Cat 4 with fallback to 3G and 2G networks. This ensures continued connectivity where network conditions vary. Dual SIM support allows automatic switching between operators for improved uptime. It also supports Wi-Fi (IEEE 802.11 b/g/n 2.4 GHz) for local wireless access. Two Ethernet ports (1 WAN/LAN and 1 LAN) allow wired device connections or integration into existing networks. Alternative link configuration enables mobile, wired, or Wi-Fi connections to be set as primary or backup, with automatic load balancing. This helps maintain stable communication across different network paths. Secure communication is supported through VPN and firewall functions. NAT and static/dynamic routing are available for structured network management.

Monitoring and Management

The device includes connection monitoring features such as ping reboot and scheduled reboot. These help maintain stable operation without manual intervention. Remote management is available via Web UI, SSH, SMS, and FOTA. This allows administrators to configure, update, and maintain devices without on-site access. LED indicators display power status, mobile signal strength, mobile status, and Wi-Fi activity, helping with quick diagnostics.

Power and Environmental Suitability

WR100LEU operates within an 8–32V DC input range. This supports both fixed installations and vehicle-based deployments. It is designed to operate in temperatures from –30 °C to +70 °C, with storage support down to –40 °C. Its compact size (90 × 90 × 24 mm) allows installation in space-limited environments.

Expansion and Interface Support

The device includes one serial port configurable as RS232 or RS485 on demand. This enables integration with industrial equipment, control systems, or legacy devices. It also features dual SMA connectors for mobile antennas and an RP-SMA connector for Wi-Fi, supporting flexible installation setups.
