A clear handoff at every layer
Five service layers for a more predictable device program.
RuggedLayer organizes access to multiple manufacturers into a consistent engagement model. Each layer has a defined input, deliverable and evidence boundary.
Service layers
- Confirm the UHF region, NFC behavior, barcode engine, SIM, storage, key mapping and Android application support.
- Test metal or mixed materials, tag spacing, operator grip, screen readability, battery rotation and offline sync.
- Review Android 9 security, MDM, charging, cleaning and replacement policies before deployment.
Deployment accessories
- Scope spare batteries, charger, hand strap, protective cover, USB-C cable and any NFC or barcode accessories.
- Keep the mode mapping, RF settings, scan profile, MDM policy and approved asset-tag samples with the handover.
RuggedLayer Test Lab
Define a useful test, not a vague benchmark.
Tell us the labels, tags, application and operating conditions that matter.
- 01
Measure UHF read, write, missed and stray events with representative short-range tags and materials.
- 02
Test barcode and NFC capture, mode switching, battery, application sync, charging and offline recovery.
- 03
Freeze the exact SKU, OS, firmware, RF profile, input map, accessories and acceptance thresholds.
