Router D-Link DWM-311-G 5G M2M Modem 2.5 Gigabit Ethernet

The D-Link DWM-311-G 5G M2M Modem is a compact industrial router with 5G connectivity and a 2.5 Gigabit Ethernet interface. Designed for machine-to-machine (M2M) applications such as EV charging stations and remote monitoring, it combines high data throughput, OpenVPN support and a rugged metal housing to provide reliable network access in demanding environments.

Advantages

The modem offers ultra-fast 5G speeds and low latency for real-time data exchange, secure VPN protection through OpenVPN for safe remote access, and automatic 4G/5G switching for stable connectivity. Its corrosion-resistant zinc-plated steel case and wide operating voltage range (VDC 5–32V) ensure durability and flexible power options. The single 2.5 Gigabit Ethernet port supports 10/100/1000/2500 Mbit/s rates, enabling high-throughput wired connections.

Suitable for

• EV charging station connectivity and remote management
• Industrial M2M telemetry and sensor data collection
• Remote site access where wired infrastructure is limited
• Applications requiring secured VPN connections and low-latency communications
