D-Link 4G LTE (Cat 4) to Gigabit Ethernet Modem/Bridge

The D-Link DWM-311-B1 is a 4G LTE Cat 4 modem and Ethernet bridge that lets you bring internet service to places where cable or fiber are not practical. Insert a micro-SIM card, connect the Gigabit Ethernet port to your equipment, and the unit immediately delivers mobile broadband from carriers such as Verizon or AT&T.

This modem was built for industrial and commercial settings. A zinc plated steel enclosure resists knocks and vibration, and the electronics keep working in temperatures from -22 to 140 °F. Power arrives through a common Micro USB connector, and the included hardware supports both wall and DIN-rail mounting, so installers can tuck it into control cabinets, kiosks, or outdoor enclosures without special tools.

Integrators often use the DWM-311-B1 inside ATMs, vending machines, surveillance cameras, and digital signage. Construction sites, pop-up retail locations, and remote offices also rely on it as either a primary link or a backup path when wired service drops. OpenVPN support protects traffic traveling over public cellular networks, while the optional D-ECS cloud platform lets IT staff monitor status, push updates, and diagnose issues from anywhere.

In short, if you need dependable connectivity in a challenging environment, this modem gives you a straightforward way to keep critical devices online.
