The Warehouse with Blind Zones That Were Costing Thousands

A 15,000 m² logistics distribution center in the San Pedro de Macorís Zone operated with 200 wireless barcode scanners, 40 pistol-grip picking terminals, and IoT temperature sensors for refrigerated products. The problem: 35% of the warehouse had poor or no WiFi coverage. Operators in those zones lost connectivity, had to manually reconfirm each scan, and inventory errors were costing an estimated $8,000 monthly in misclassified merchandise.

The Unique Challenges of Industrial WiFi

A warehouse is not an office. The metal of 10-meter-high shelving creates Faraday cages that completely block signals. Moving forklifts cause dynamic signal reflections. Electric motors generate electromagnetic interference on 2.4GHz.

The Engineering Solution: 3D predictive heatmap modeling the real attenuation of metal shelving. 34 UniFi U7 Pro APs mounted on ceiling beams at 8 meters height, aimed downward at a calculated angle to maximize coverage between aisles. Exclusive 5GHz channel for scanners running low-latency protocol.
  • Resulting coverage: 100% of operational area with signal >-65dBm. Complete elimination of blind zones.
  • Error reduction: Inventory errors due to connectivity loss dropped 98%. Project ROI was positive in the second month.
  • Seamless roaming: Forklifts with integrated scanners move throughout the warehouse without any session interruption thanks to 802.11r Fast Roaming configured across all APs.

Do you have a warehouse, industrial plant, or logistics space with WiFi coverage issues?
