D-Link DWM-311-G - 5G Modem/Gateway, Black

The D-Link DWM-311-G 5G NR M2M Rugged Industrial Modem is a gateway for machine-to-machine deployments. It connects remote hardware to mobile networks using 5G NR sub-6 GHz infrastructure, supporting cellular download speeds of up to 3.4 Gbit/s depending on carrier conditions. Integrated 4G fallback ensures continuous operation if the 5G signal drops. Unlike consumer routers, this industrial modem is designed for wired integration and does not broadcast a Wi-Fi signal; it relies entirely on the cellular data link to provide network access to connected equipment.

The device features a zinc-plated steel housing designed to withstand demanding environments. A 2.5 Gbit/s Ethernet LAN port provides a high-speed interface for edge controllers or network switches. Power is supplied via a 5–32 V DC input. Administrators insert a 3FF Micro SIM card into the dedicated slot to establish the connection, and the web-based interface simplifies configuration. Plug-and-play support streamlines integration into existing industrial networks.

• Four SMA(F) cellular connectors: allow the attachment of external antennas for improved signal reception.
• OpenVPN support: establishes encrypted tunnels for remote management.
• LTE Cat. 19 (DL) and Cat. 18 (UL) fallback: maintains high-bandwidth performance on 4G networks.
• Advanced routing: includes NAT, port forwarding, and Dynamic DNS (DDNS) for local traffic control.
• Built-in DHCP server: automates IP address assignment for downstream devices.
• SMS compatibility: supports remote status monitoring and alert notifications.
