Industrial 4G LTE Gateway with Serial and Wi-Fi
The IMG-4312D+-D4G_US is a rugged device server built for industrial IoT and M2M deployments. It combines LTE Cat 4 cellular, dual Ethernet, Wi-Fi, and an RS-232/422/485 serial port to connect legacy equipment and sensors to cloud platforms. Dual SIM redundancy and VPN support suit remote sites where wired broadband is unavailable or unreliable. DIN-rail mounting and a wide temperature range fit cabinet and vehicle installations.
Cellular and Ethernet limits
LTE operates on FDD bands 2, 4, 5, 12, 13, 14, 66, and 71 with UMTS fallback on 1900, 1700, and 850 MHz. Wi-Fi covers 2.412 to 2.462 GHz across 11 channels under FCC rules. The two RJ45 ports negotiate at 10/100 Mbps only, so throughput caps at Fast Ethernet speeds. VPN encryption runs over these links using OpenVPN, PPTP, or IPSec for secured tunnels.
Build and connector implications
The unit measures 1.77 by 3.17 by 3.74 inches and weighs 13.93 ounces, designed for DIN-rail mounting inside enclosures. Operating temperature spans -25 to 70°C with storage down to -40°C and humidity up to 95% non-condensing. A DB9 connector carries the serial interface, while dual SIM slots sit behind a panel for carrier failover. CE and FCC certification plus AT&T, Verizon, and FirstNet approvals confirm regulatory compliance for North American deployments.

Questions about this item
How do I choose between the LTE and Wi-Fi versions of the IMG-4312D+-D4G_US?
This single model includes both LTE Cat. 4 and IEEE 802.11b/g/n Wi-Fi, so no separate version choice is needed.
What real-world throughput can I expect from the two 10/100Base-T(X) LAN ports?
Each RJ45 port negotiates at 10 or 100 Mbps full-duplex; actual throughput depends on the cellular link and network load.
Which frequency bands does the LTE modem support for AT&T, Verizon and FirstNet?
FDD bands 2, 4, 5, 12, 13, 14, 66 and 71 at 1900, 1700, 850, 700 and 600 MHz cover all three carriers.
