Zebra TC78A1-3T1K4B1A10-NA 5G WWAN Rugged Android Mobile Computer
Overview
The Zebra TC78A1-3T1K4B1A10-NA is a 6-inch full-touch rugged mobile computer built for field and warehouse teams that need wide-area connectivity without giving up long-range scanning or drop protection. This configuration pairs Sub-6 5G WAN with Wi-Fi 6E, an SE55 advanced-range scan engine, and an IP68 sealed housing over Corning Gorilla Glass — the combination that matters when a device has to move between a dock, a yard, and a delivery vehicle in the same shift. Whether you're outfitting route drivers, field service techs, or DC receiving staff, TC78A1-3T1K4B1A10-NA is built to stay online and stay readable through drops, dust, and long scan distances.
Key Features
- Qualcomm Snapdragon 6490 (2.7 GHz) with 4GB RAM / 64GB Flash: enough headroom to run WMS, POD capture, and barcode middleware simultaneously without the lag that kills throughput on a receiving dock.
- Sub-6 5G WAN + Wi-Fi 6E: 5G keeps the device connected to backend systems outside four walls (last-mile delivery, field service), while Wi-Fi 6E adds cleaner, less congested indoor throughput in facilities packed with other 2.4/5GHz devices — fewer dropped sessions during peak scan activity.
- SE55 Advanced Range scan engine, 40ft scan distance: reads barcodes on high steel racking or across a truck bed without walking up to the label — a real cycle-time saver in tall-rack warehouses and yard checks.
- IP68 sealed housing: stands up to washdown, rain, and dust intrusion beyond typical IP65/66 devices — relevant for cold chain, outdoor delivery, and food/beverage environments where hose-down cleaning is routine.
- 10ft / 2,000 drops to 3.3ft rated: engineered for repeated drops onto concrete across a full shift, not a one-time spec-sheet number — fewer cracked screens and warranty claims versus consumer-grade or lightly ruggedized devices.
- Corning Gorilla Glass display: resists scratching and impact fracture from keys, box cutters, and pallet jacks riding in the same pocket or holster.
- 4400 mAh warm-swap battery: lets workers hot-swap power mid-shift without powering down the device or losing an active session — no forced downtime waiting on a charging dock.
- 2TB microSD expansion: headroom for offline map caching, signature/photo capture, and local data logging on routes with spotty backend connectivity.
- Android operating system: aligns with Zebra's Android roadmap and standard MDM/EMM tooling, easing provisioning across large device fleets.
Integration & Compatibility
TC78A1-3T1K4B1A10-NA runs Android, so it integrates with standard Android-based EMM/MDM platforms for zero-touch provisioning, app push, and remote lock/wipe across a fleet. The SE55 scan engine supports standard 1D/2D barcode workflows used in WMS, TMS, and field service apps without custom scanning SDK work in most cases. Sub-6 5G WAN means the carrier/SIM configuration should be confirmed against your carrier's supported bands before large-scale rollout. If your deployment is fixed-location warehouse only with strong Wi-Fi coverage and no cellular requirement, a Wi-Fi-only TC78 configuration in the same family is worth comparing — you'd skip the WAN data plan and cost while keeping the same SE55 scanning and ruggedness profile. For teams standardizing on a single device across both indoor and outdoor routes, this WWAN configuration removes the need to carry a second connectivity-limited unit.
Frequently Asked Questions
Q: What connectivity does the TC78A1-3T1K4B1A10-NA support?
A: This configuration includes Sub-6 5G WAN and Wi-Fi 6E, along with standard Wi-Fi, giving it both wide-area cellular and high-density indoor wireless coverage.
Q: How far can the SE55 scan engine read barcodes?
A: The SE55 Advanced Range engine on this unit is rated to scan at distances up to 40ft, suited for high-rack warehouse and yard scanning.
Q: What's the drop rating on the TC78A1-3T1K4B1A10-NA?
A: It's rated for 10ft drops to concrete and 2,000 drops from 3.3ft, with an IP68 seal against dust and water.
Q: Can the battery be swapped without shutting the device down?
A: Yes, the 4400 mAh battery supports warm-swap, so the device stays powered through a battery change.
Q: How much storage does the TC78A1-3T1K4B1A10-NA have?
A: It ships with 4GB RAM and 64GB internal flash, plus support for up to a 2TB microSD card for additional storage.
Q: What's the warranty on the TC78A1-3T1K4B1A10-NA?
A: It carries a 1-year manufacturer warranty.
The spec that jumps out on the TC78A1-3T1K4B1A10-NA is the SE55 Advanced Range engine pulling a 40ft scan distance — paired with Sub-6 5G WAN, this is the configuration I point field service and yard operations toward when Wi-Fi-only devices keep dropping sessions at the edge of a facility.
Technical Highlights:
- Snapdragon 6490 @ 2.7GHz, 4GB/64GB: handles concurrent WMS and scanning middleware without the frame drops you get on older Snapdragon 660-class TC devices.
- SE55 scan engine at 40ft: cuts walk-time on tall rack aisles and truck-bed label checks compared to standard-range engines topping out closer to 15-20ft.
- IP68 + 10ft / 2,000-drop rating: built for washdown and repeated concrete drops across a full shift, not just a lab spec test.
Deployment Considerations:
- Confirm your carrier's 5G Sub-6 band support before large fleet rollouts — WWAN performance depends on local network alignment, not just device capability.
- If your operation is entirely indoor with solid Wi-Fi coverage, the 5G WAN radio in this SKU is paying for capability you may not use — a Wi-Fi-only TC78 variant in the same family is worth pricing out first.
I'd spec the TC78A1-3T1K4B1A10-NA for last-mile delivery and field service fleets that move between warehouse docks, outdoor yards, and customer sites in the same shift — the 5G WAN plus 40ft SE55 scanning covers both the connectivity gap and the long-range scanning gap in one device.
