Deliver high-speed cellular connectivity where wired service is unavailable, costly, or too slow to deploy. The D-Link DWM-311-G is a 5G NR M2M modem designed for industrial and edge environments that need reliable machine-to-machine communications with modern cellular performance and secure remote access. With 5G and LTE support, this modem gives infrastructure teams a practical path to connect controllers, kiosks, gateways, and other networked equipment without depending on fixed broadband. The 2.5 Gigabit Ethernet interface provides a stronger wired handoff than legacy Fast Ethernet or Gigabit-only designs, helping the modem keep pace with higher-throughput edge devices. VPN support adds a security layer for remote management and protected data transport, while the rugged design makes it better suited to harsh or space-constrained installations than consumer-grade cellular hardware. For organizations that need dependable uptime and a cleaner deployment model, this modem is built to justify itself in the field.
