The Cradlepoint S750 is an LTE router in a semi-ruggedized aluminum housing, built for IoT, light industrial and mobile applications where security is a baseline requirement. This part number, TAA-TB03-0750C4D-NA, is the TAA-compliant ordering option for the U.S. Federal Government. It combines the S750 in its Cat 4 (150 Mbps) configuration without Wi-Fi with a 3-year NetCloud IoT Essentials plan. The embedded Cat 4 LTE modem delivers peak rates of 150 Mbps down and 50 Mbps up with 2x2 MIMO. Dual 4FF SIM slots use SIM-based auto-carrier selection. The modem covers North American LTE bands 2, 4, 5, 12, 13, 14, 66 and 71. It carries AT&T, T-Mobile and Verizon network certifications plus FirstNet Trusted, T-Mobile Connecting Heroes and Verizon Frontline public safety certifications. Two switchable LAN/WAN Gigabit Ethernet ports connect local equipment, and a USB 2.0 port supports a locking USB RS232 adapter connection. Active GNSS (GPS, GLONASS, BeiDou, Galileo) supports asset tracking and geofencing. The router accepts 9-33 VDC input with reverse polarity and transient protection plus ignition sensing, so it suits vehicle installs. It is rated IP30 and operates from -20 °C to 60 °C. It meets MIL-STD-810H vibration and shock methods, SAE J1455 vehicle vibration and EN 61373 rail rolling-stock standards. Calculated MTBF for the S750-C4D is 483,373 hours. The NetCloud IoT Essentials plan provides NetCloud Manager device management and software updates for the full 3-year term. Support covers phone 24 hours on weekdays with emergency response on weekends, web 24x7 and chat 24x5. The hardware carries a limited lifetime warranty while the subscription is active. NetCloud Advanced and NetCloud Exchange can be added at any time. The Cradlepoint S700 series datasheet documents the full specification.
