4G LTE PoE Modem D-Link DWM-314-TP with Power over Ethernet and SIM slot

D-Link DWM-314-TP is a 4G LTE PoE modem that provides mobile broadband connectivity through a standard SIM card. The unit integrates LTE data access with Power over Ethernet capability to deliver network and power over a single cable, simplifying installation in locations without fixed-line internet or convenient power outlets. The DWM-314-TP is designed for use in remote sites, retail environments, point-of-sale terminals and temporary deployments that require a stable cellular internet connection.

Advantages

The modem supports 4G LTE connectivity combined with PoE to reduce cabling and installation complexity while enabling placement in locations where AC power is not readily available. Its SIM slot allows straightforward activation with a cellular data plan, and the device maintains continuous data access for applications that require reliable uptime. Compact form factor and industry-standard Ethernet interface ensure compatibility with existing network equipment.

Suitable for

• Remote sites and field locations without fixed broadband
• Retail stores and point-of-sale (POS) systems
• Temporary installations such as events or construction sites
• Failover or backup internet for small offices and branch locations

Key specifications

• Cellular standard: 4G LTE data connectivity
• Power: Power over Ethernet (PoE) support for combined network and power delivery
• SIM interface: Integrated SIM slot for cellular SIM cards
• Network interface: Ethernet port for LAN connection and device integration
• Form factor: Compact modem designed for wall or rack-adjacent placement

How to use

Install a compatible SIM card with an active data plan into the modem's SIM slot and connect the device to a PoE-enabled switch or PoE injector to power the unit and provide network connectivity over a single Ethernet cable. Configure basic network settings through the modem's management interface to match the cellular operator and local network requirements. Place the device in a location with good cellular signal or use an external antenna if required by the site conditions.

Recommendations

For reliable performance, verify cellular coverage and data plan allowances before deployment, ensure PoE equipment meets the modem's power requirements, and position the modem to maximize signal reception. Use the modem as a primary connection where fixed-line options are unavailable or as a failover solution for critical services.
