Section 1 - Product Overview
Introduction
The D-Link DWM-312 4G LTE M2M Router is an easy-to-deploy, high-performance 3G/4G router. It features a dedicated Fast
Ethernet port and dual-SIM 4G LTE mobile broadband for maximum redundancy and exibility for intense
Machine-to-Machine (M2M) applications. Powerful VPN tools and advanced remote management combined with ease of
use make the DWM-312 ideal for both large-scale and individual deployments.
Easily connect to your high-speed 3G/4G LTE mobile connection with the DWM-312 4G LTE M2M Router, and enjoy fast
downlink speeds of up to 150 Mbps1 and uplink speeds up to 50 Mbps1, giving you the speed you need for fast, responsive
Internet access. Deploy it in a remote location to access IP cameras and systems remotely. The blazing fast LTE connection
allows multiple users to access e-mail and stream music and video on the go. Congurable dual-SIM fallback provides
reliability and exibility in mixed network environments.
The DWM-312 4G LTE M2M Router’s integrated VPN Client and Server support almost any VPN policy. The router’s hardware
engine can support and manage multiple VPN congurations. It supports IPSec, PPTP, L2TPv2, and GRE protocols in Server
mode, and handles pass-through trac as well. Advanced VPN conguration options include multiple encryption options,
key management, negotiation modes, and VPN authentication using an internal user database.
The industrial-grade casing means the DWM-312 provides reliable high-speed connectivity in extreme conditions. The
corrosion-resistant zinc-plated steel case and wide operating temperature and humidity tolerance mean that the DWM-312
is ready for the most demanding M2M applications in virtually any environment. Wall mounts allow the DWM-312 to be
mounted virtually anywhere for optimal connectivity. Flexible power input allows the router to be powered by any
convenient power source.

Installation
This section will guide you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in an attic or garage.
Before You Begin
Observe the following precautions to help prevent shutdowns, equipment failures, and personal injury:
• Install the DWM-312 in a cool and dry place. Refer to the technical specications in the user
manual for the acceptable operating temperature and humidity ranges.
• Install the router in a site free from strong electromagnetic sources, vibration, dust, excessive moisture, and direct sunlight.
• Place antennas in an unobstructed area with clear mobile signal. Avoid metal boxes, brick walls, and other dense
materials. It is recommended to use the web interface to conrm signal strength before permanent installation.
• Visually inspect the power connector and make sure that it is fully secure.
• Do not stack any devices on top of the router.
