D-Link DWM-311-G 5G NR Industrial M2M VPN Modem
PRODUCT DESCRIPTION
D-Link DWM-311-G 5G NR Industrial M2M VPN Modem (DWM-311-G) - 3 Years Local Warranty
5G Speed for Connected Machines
The D-Link DWM-311-G is a compact 5G M2M modem built on a 3GPP Rel. 16 5G/4G module. It supports 5G SA and NSA on Sub-6 GHz, with D-Link-rated throughput of up to 3.4 Gbps downlink (5G NSA) and LTE fallback (DL Cat.19 / UL Cat.18).
2.5 GbE Wired Connection
A single 2.5 Gigabit RJ45 LAN port carries that bandwidth to your equipment — ideal for EV chargers, digital signage, kiosks and remote cameras that need a fast, plug-and-play cellular uplink.
Industrial-Grade Design
A robust metal build, -30 to 70 °C operating range, wide DC 5-32 V terminal-block input and wall or DIN-rail mounting suit roadside cabinets and plant rooms.
VPN, SMS and Cloud Management
An OpenVPN client secures traffic, SMS event management sends alerts, and units can be configured via Web UI or SSH and managed centrally with D-Link D-ECS2.
