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 Mbps1and 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. Congurable 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 congurations. It supports IPSec, PPTP, L2TPv2, and GRE protocols in Server
mode, and handles pass-through trac as well. Advanced VPN conguration 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.
