The D-Link DWM-313 is a 4G M2M router using LTE Cat 4 for download speeds of up to 150 Mbps and uploads of up to 50 Mbps. Two Micro SIM slots and a Fast Ethernet port that can be configured as a WAN provide failover between carriers and between 4G and wired broadband. Built-in Wi-Fi N150 on 2.4 GHz connects local devices and gives technicians easy access for remote maintenance, while a Micro SD slot stores logs. IPSec, OpenVPN, PPTP, L2TP and GRE VPN support secures the link, with management through the web interface, CLI, SNMP or D-Link's D-ECS platform (licence fees apply). A metal casing rated for -30 to 70°C, a DC 5V power supply and an included DIN-rail kit suit it to shops, remote branches, mobile offices and pop-up booths.
