What's the difference between a 1D laser scanner and a 2D imager on a mobile computer?
A 1D laser scans a single barcode line; it's fast and cheap but can't read QR codes, Data Matrix, or barcodes on curved surfaces. A 2D imager captures a photo of the barcode, reads all formats, tolerates dirt and wrinkles, and works at multiple angles. Modern WMS systems require 2D; 1D is obsolete for new deployments.
How do I choose between Android and Windows mobile computers?
Android is faster to deploy, has a modern app ecosystem, and lower total cost of ownership. Windows is better for legacy ERP integration, long-term vendor support contracts, and enterprises with existing Windows infrastructure. Test both OS versions with your WMS vendor before committing to a fleet.
What battery life should I expect, and how does it impact my shift scheduling?
Standard batteries last 8–10 hours; extended batteries reach 12–14 hours. For 16-hour operations, use hot-swap battery models or invest in mid-shift charging docks. Cold environments reduce battery life by 20–30%; factor this into your deployment and dock placement strategy.
How many mobile computers do I need for my warehouse?
Use a 1-device-per-200-sq-ft rule as a baseline, then adjust for shift overlap and redundancy. A 50,000 sq ft warehouse with 2 shifts typically needs 12–18 devices; add 20% spares for rotation and repairs. Test your actual throughput (picks/hour) before finalizing fleet size.
What's the real-world wireless range of a mobile computer in my warehouse?
Advertised range (100+ meters) assumes open space; actual warehouse range is 30–50 meters due to metal racking, concrete, and interference. Site-survey your AP locations and conduct a real-world RF walktest before purchase. Poor RF coverage kills throughput faster than slow devices.
Are refurbished or certified pre-owned mobile computers a good fit for our operations?
CPO devices from reputable distributors can cut costs 30–40% and work well for non-critical zones (returns, QA) or temporary projects. Always verify drop-test history and battery health; avoid CPO units for high-volume picking where downtime is expensive. Budget for 12-month warranty coverage on CPO fleets.
