In today’s fast-paced warehouse environments, mobile computing devices are the backbone of efficient operations. From receiving and putaway to picking and shipping, handheld scanners and mobile computers enable real-time data capture, inventory accuracy, and seamless workflow management. However, not all devices are created equal, and choosing the wrong equipment can lead to frequent replacements, productivity losses, and frustrated workers.
At Ahearn & Soper Inc., we help businesses navigate the complex landscape of rugged mobile devices. This guide will walk you through the key considerations for selecting handheld scanners and mobile computers that will truly stand up to your warehouse environment.
Understanding Your Environment
The first step in selecting the right mobile device is conducting an honest assessment of your operating environment. Different warehouses present vastly different challenges, and your device selection should reflect these realities.
Temperature Extremes
Does your facility include freezer storage? Are devices moving between climate-controlled areas and loading docks exposed to outdoor temperatures? Standard mobile computers typically operate in temperatures ranging from 0°C to 50°C, but cold storage environments demand devices rated for -20°C to -30°C or lower. These specialized units feature heated batteries and screens designed to remain responsive even when frozen.
Exposure to Elements
Consider the level of exposure to dust, moisture, and liquids. The IP (Ingress Protection) rating system provides clear guidance here. An IP65 rating offers protection against dust and water jets, suitable for most indoor warehouses. However, facilities handling beverages, food processing, or those with frequent washdowns may require IP67 or IP68 ratings, which protect against temporary water immersion.
Drop and Impact Frequency
How often will devices be dropped, and from what height? A typical warehouse environment sees devices dropped 3-5 feet regularly onto concrete floors. Look for devices with drop specifications that exceed your typical drop heights. Military-standard testing (MIL-STD-810G or 810H) provides additional assurance of impact resistance, tumble durability, and vibration tolerance.
Indoor vs. Outdoor Usage
If workers move between indoor warehouse space and outdoor loading areas, screen visibility becomes critical. Standard LCD screens wash out in direct sunlight, while high-brightness displays (500+ nits) with outdoor-viewable technology remain readable regardless of lighting conditions.
Evaluating Durability Requirements
Beyond environmental factors, consider how devices will be used throughout the workday.
Build Quality Matters
Rugged devices come in three general categories: consumer-grade with protective cases, semi-rugged, and fully rugged. While consumer devices with cases may seem cost-effective initially, they rarely survive warehouse conditions long-term. Semi-rugged devices balance durability with lighter weight and lower cost, suitable for controlled environments with careful handling. Fully rugged devices, though more expensive upfront, offer the lowest total cost of ownership in demanding environments.
Battery Performance
Battery life directly impacts productivity. Workers shouldn’t need to swap batteries mid-shift or worry about devices dying during critical tasks. Look for devices offering 8-12 hour battery life under typical usage patterns. Hot-swappable battery options allow users to replace batteries without powering down, preventing data loss and maintaining productivity. For 24/7 operations, consider devices with dual battery systems.
Scanning Technology
The scanning engine is the heart of your mobile device. Laser scanners work well for 1D barcodes in good condition but struggle with damaged codes or 2D barcodes. Imager-based scanners read both 1D and 2D barcodes, capture images, and handle damaged or poorly printed codes more effectively. For long-range applications like high-bay storage, extended-range scanners can read codes from 30-50 feet away, eliminating the need for lifts or ladders.
Form Factor Considerations
Mobile devices come in various form factors, each suited to different applications.
Gun-Style Handheld Computers
These pistol-grip devices excel in high-volume scanning environments. The ergonomic design reduces fatigue during extended scanning sessions, and the form factor naturally positions the scanner for optimal barcode reading. They typically feature larger screens (4-6 inches) and full numeric or QWERTY keyboards, ideal for applications requiring data entry alongside scanning.
Brick-Style Mobile Computers
Compact and pocketable, brick-style devices work well for workers who need to scan occasionally while performing other tasks. They’re lighter and less bulky than gun-style devices but may cause more hand fatigue during extended scanning sessions. These devices suit putaway, cycle counting, and receiving applications where mobility matters more than sustained scanning.
Wearable Devices
Ring scanners, wrist-mounted computers, and arm-mounted devices keep workers’ hands free for material handling. Voice-directed systems paired with wearable devices optimize picking operations, allowing workers to maintain focus on the task rather than looking at screens. These solutions particularly excel in high-volume picking and sortation applications.
Tablets and Vehicle-Mounted Computers
For forklift operators and workers who need larger screens for complex applications, vehicle-mounted terminals and rugged tablets provide the solution. These devices withstand constant vibration and feature screens large enough for detailed inventory management, route planning, and multi-step processes.
Integration Requirements
The most durable device in the world won’t deliver value if it doesn’t integrate seamlessly with your existing systems.
Operating System Compatibility
Most warehouse management systems support both Android and Windows operating systems. Android has become increasingly dominant in the mobile device market, offering regular updates, extensive app ecosystems, and generally lower device costs. Windows devices remain relevant in environments with legacy applications or specific software requirements. Verify that your chosen operating system supports all critical applications before committing to a platform.
Wireless Connectivity
Modern warehouses rely on wireless connectivity for real-time data synchronization. Wi-Fi connectivity is standard but verify that devices support your wireless infrastructure’s frequency bands and security protocols. Some facilities require dual-band support (2.4 GHz and 5 GHz) for optimal performance. Bluetooth connectivity enables integration with peripheral devices like printers and headsets. For outdoor or campus-style operations, cellular connectivity (4G LTE or 5G) provides coverage beyond Wi-Fi networks.
Software and Application Deployment
Consider how you’ll deploy applications and updates across your mobile device fleet. Modern enterprise mobility management (EMM) solutions enable remote device provisioning, application deployment, and security policy enforcement. Devices should support kiosk mode or lockdown features that restrict access to only approved applications, preventing unauthorized use and reducing support overhead.
Data Capture Options
Beyond barcode scanning, consider whether you need additional data capture capabilities. RFID readers enable bulk reading of tagged items without line-of-sight scanning. Built-in cameras support signature capture, photo documentation, and OCR (optical character recognition) for manual data entry scenarios. Some environments benefit from NFC (near-field communication) for employee authentication or asset tracking.
Total Cost of Ownership Analysis
Initial purchase price represents only a fraction of true device costs over the ownership lifecycle.
Device Longevity
Fully rugged devices typically last 5-7 years in demanding environments, compared to 1-2 years for consumer-grade alternatives. While rugged devices cost 2-3 times more initially, their extended lifespan dramatically reduces replacement costs.
Service and Support
Evaluate manufacturer warranties and service options. Next-business-day replacement services minimize downtime when devices fail. Depot repair services offer cost savings but require maintaining spare devices for continuity. Comprehensive coverage plans that include accidental damage protection reduce unexpected repair costs.
Accessories and Charging Infrastructure
Factor in costs for charging cradles, spare batteries, protective accessories, and mounting solutions. Multi-bay chargers that can charge 4-6 devices simultaneously offer better space utilization than individual chargers. Vehicle charging solutions ensure forklift-mounted devices remain powered throughout shifts.
Training and Adoption
Intuitive devices reduce training time and improve adoption rates. Touchscreens, familiar Android interfaces, and well-designed applications enable faster user proficiency compared to complex legacy systems.
Making the Right Choice
Selecting mobile computing devices requires balancing multiple factors. Start by documenting your specific requirements across these dimensions:
Environmental Conditions: Temperature ranges, exposure to moisture and dust, drop heights, and lighting conditions
Application Requirements: Primary use cases, scanning volume, data entry needs, and special requirements like RFID or long-range scanning
Integration Needs: WMS compatibility, wireless infrastructure, security requirements, and peripheral devices
Budget Constraints: Initial investment capacity, ongoing support costs, and replacement cycles
Fleet Size: Number of devices needed, scalability requirements, and spare device strategy

The Path Forward
Mobile computing technology continues evolving rapidly. Today’s devices offer capabilities that seemed impossible a decade ago: longer battery life, faster processors, better scanning engines, and more durable construction. However, these advances only deliver value when properly matched to application requirements.
Take time to assess your needs thoroughly, involve end users in the selection process, and pilot devices before committing to full fleet deployment. The right mobile devices become invisible tools that simply work, enabling your workforce to focus on moving product rather than managing technology.
