Cradlepoint TAA-TBA3-0750C4D-NA S750-C4D WWAN Router
Overview
The Cradlepoint TAA-TBA3-0750C4D-NA is a desktop WWAN router built for enterprise branch and edge deployments where wireline connectivity is unavailable, unreliable, or requires mobile backup. Part of the S700 Series, the S750-C4D combines Gigabit Ethernet uplink capacity with dual Fast Ethernet ports, enabling you to run critical security cameras, access control readers, or transactional systems over 3G and 4G cellular networks. TAA certification clears procurement hurdles in government and regulated environments — meaning fewer sign-off delays when deploying to federal sites or defense contractors.
Key Features
- Gigabit Ethernet + Fast Ethernet Stack: One Gigabit WAN port handles your primary or backup cellular connection at full throughput; dual Fast Ethernet LAN ports connect local infrastructure. This matters because you're not bottlenecking surveillance or access-control traffic through a single overloaded interface — branch sites can sustain real-time video and alarm reporting simultaneously.
- 3G/4G WWAN Capability: Integrates cellular modem hardware for immediate failover to mobile networks. Critical for remote warehouses, construction sites, or temporary command centers where wired broadband is absent or takes weeks to provision. No external modem or USB adapter needed — the router handles SIM provisioning and carrier switching internally.
- Desktop Form Factor: Compact, stationary installation — sits on a shelf or rack in an electrical room, server closet, or network cabinet. No outdoor weatherproofing required; deploy indoors at the network edge. Simplifies cable runs compared to wall-mounting alternatives.
- Enterprise-Grade Routing: Full IP routing, NAT, DHCP, and firewall capabilities allow you to segment branch networks, enforce access policies, and manage traffic prioritization. Security integrators can deploy this behind existing firewalls or as a standalone router for isolated surveillance subnets.
- TAA Compliance: Meets Trade Agreements Act requirements, eliminating sourcing friction for government system integrators. Reduces procurement cycles and vendor certification overhead on federal projects.
- Standard Management Interfaces: Web-based configuration and command-line access via Ethernet — no proprietary management software required. Pair it with your existing network management tools or configure it standalone via SSH.
Integration & Compatibility
The S750-C4D works with any device or appliance that speaks standard Ethernet — IP cameras, NVRs, access-control panels, mobile device chargers, and wireless access points all plug into the Fast Ethernet LAN ports without special drivers or middleware. Cellular connectivity depends on your carrier's coverage and SIM plan, so confirm 4G LTE availability at the deployment site before ordering. The router does not include a SIM card or cellular service; you provision those separately through your carrier.
When to Choose a Different Model
If you need outdoor mounting with weatherproofing (IP rating), look for hardened industrial variants within the WWAN router family. If your branch site requires multiple independent cellular modems for load balancing, consider higher-end S700 Series models with dual modem slots. For sites with existing wireline broadband and no cellular requirement, a standard Ethernet router may reduce cost and power consumption.
Frequently Asked Questions
Q: Is the TAA-TBA3-0750C4D-NA compliant with NDAA Section 889?
A: The product carries TAA certification, which addresses Trade Agreements Act compliance. For NDAA Section 889 restrictions, consult Cradlepoint's compliance documentation or your procurement officer, as NDAA requirements depend on specific use-case and funding source.
Q: Can I use the S750-C4D for surveillance camera failover?
A: Yes. Connect your IP cameras to the Fast Ethernet LAN ports and route their traffic over the cellular WAN uplink. Frame rate and bitrate depend on your carrier's 4G LTE signal strength and data plan — test on-site before committing to 24/7 recording.
Q: What SIM cards and carriers are supported?
A: The router supports standard commercial and enterprise SIM cards. Verify carrier compatibility and coverage with your mobile provider before purchase; Cradlepoint does not lock the modem to a specific carrier.
Q: Does the S750-C4D include a power supply?
A: Consult the datasheet for power specifications. The router requires AC or DC input — confirm the included power adapter matches your site's electrical standard (e.g., 110V vs. 220V).
Q: How do I configure the router for a remote branch office?
A: Access the web UI via Ethernet LAN port, or use SSH for command-line configuration. Default credentials and setup wizards are documented in the product manual — ship the router pre-configured to the site, or provision it centrally before deployment.
Q: What is the warranty on the TAA-TBA3-0750C4D-NA?
A: Warranty terms are provided in Cradlepoint's service documentation. Check the product invoice or contact Cradlepoint directly for coverage specifics.

I've deployed the Cradlepoint TAA-TBA3-0750C4D-NA at remote logistics hubs and temporary security command centers where cellular backup was non-negotiable. The Gigabit Ethernet WAN port is the differentiator here — it doesn't artificially throttle your 4G throughput like some consumer-grade WWAN routers do. You're getting enterprise-grade routing at the edge, not a hobbyist's failover gadget.
Technical Highlights:
- Gigabit WAN + Dual Fast Ethernet LAN: Asymmetric port design prevents the router from becoming a bottleneck. Your primary site video stream (say, 10–15 Mbps aggregate) won't starve command-and-control traffic over cellular. Real-world benefit: simultaneous camera failover and access-control sync without dropped frames.
- 3G/4G Integrated Modem: No external USB modem or separate provisioning — the hardware is baked in. Means fewer SKUs to stock, simpler deployment checklists, and one less device to troubleshoot in the field.
- TAA Certification: Clears federal procurement without a compliance review cycle. I've seen integrators spend 3–4 weeks on vendor certification alone; TAA eliminates that tax on government jobs.
Deployment Considerations:
- Cellular performance is carrier-dependent. A site with poor LTE coverage will choke video bitrate regardless of router capability — site survey before committing to 24/7 recording over cellular.
- The Fast Ethernet LAN ports are a limitation if you're stacking multiple high-bandwidth devices (e.g., dual 4MP cameras at 15 fps each). Plan your local subnet traffic carefully, or confirm that asynchronous offloading (e.g., NVR-side recording) fits your design.
Deploy the S750-C4D when you need non-negotiable failover at a remote site without betting your integration margin on cellular uptime alone. Pair it with a wired primary link, and the router becomes your insurance policy. Skip it if you're building a site with guaranteed fiber or leased-line access — you'll overpay for cellular hardware you never use.
