Project Overview: Madrid Elevator LCD Android TV Stick Deployment
In early 2026, Wanlin Electronics successfully completed the supply and technical support of 2,643 units of the WL-TVS4K Pro Android TV Stick for a leading Elevator LCD operator in Madrid. The project represented a total contract value of approximately USD 171,795 and was completed within agreed timelines with zero customs clearance issues.
Project Requirements
| Requirement | Specification |
|---|---|
| Product | Wanlin WL-TVS4K Pro Android TV Stick |
| Quantity | 2,643 units |
| Deployment Location | Madrid, Europe |
| Application | Elevator LCD environment |
| Certification Required | CE + FCC + UKCA + RoHS |
| Custom Requirements | White-label firmware, local language UI, pre-installed APKs |
| Delivery Timeline | 20 business days (sea freight) |
Implementation Process
- Week 1–2: Technical specification review and sample validation. Client testing of pre-production sample in Madrid facility.
- Week 3–4: Custom firmware development — Madrid regional language pack, branded launcher, pre-installed content apps.
- Week 5–6: Mass production with in-line QC. CE + FCC + UKCA + RoHS compliance verification batch testing.
- Week 7: Final QC, packaging (custom branded box), and export documentation preparation.
- Week 8–9: Shipment via sea freight (FOB Shenzhen → Madrid port). All customs documents provided.
- Week 10: Arrival and successful customs clearance. Client confirms receipt and installation begins.
Key Challenges and Solutions
Challenge 1 — Local Content App Integration: The client required pre-installation of 3 proprietary Elevator LCD management applications. Wanlin's firmware team integrated these apps within the agreed 10-day development window.
Challenge 2 — Customs Certification: Madrid customs required CE + FCC + UKCA + RoHS test reports in English with specific format. Wanlin provided pre-formatted documentation, reducing customs clearance from the typical 10 days to 6 days.
Challenge 3 — Bulk Packaging: 2,643 units required Madrid-standard packaging with bilingual (English + local language) product labels. Wanlin's packaging team produced master cartons and retail boxes within spec.
Results Achieved
| KPI | Target | Achieved |
|---|---|---|
| Defect Rate at Arrival | <0.5% | 0.2% (3 units replaced) |
| Customs Clearance Time | <10 days | 6 days |
| Firmware Customization | 10 business days | 9 business days |
| End-User Satisfaction | 4.5/5.0 | 4.8/5.0 |
| Re-order Within 90 Days | N/A | Yes — 1,500 units |
