Warehouse WiFi failures are expensive. Scanner drops during dispatch cause shipment delays. CCTV blind spots create security gaps. WMS disconnections cause inventory inaccuracies. Most of these problems are caused by poor planning before deployment. This 12-point checklist helps warehouse managers and logistics heads avoid the most common mistakes — whether you’re deploying fresh or fixing an existing network.

1. Do a Physical Heatmap Survey Before Placing Any AP

Never place access points based on a floor plan alone. Metal shelving, forklifts, and column layouts cause RF interference that is impossible to predict on paper. A proper WiFi heatmap survey walks the actual floor with signal measurement tools and identifies dead zones, interference sources, and optimal AP placement. Any vendor who skips this step is guessing.

2. Use Industrial-Grade Access Points — Not Office APs

Office access points are designed for drywall buildings with line-of-sight. Warehouses have metal racks, concrete floors, high ceilings, and machinery. Industrial-grade APs are built for these environments — rated for temperature extremes, dust, and RF interference. Using an office AP in a warehouse is like using a car tyre on a truck.

3. Separate CCTV Traffic from Scanner Traffic

Putting cameras and scanners on the same WiFi network is a common mistake. HD CCTV uses 3–5 Mbps per camera. If you have 20 cameras and 10 scanners on one network, the cameras eat all the bandwidth and scanners drop. Use separate VLANs with dedicated bandwidth for cameras and scanners.

4. Ensure Your Internet Link Has Enough Uplink Bandwidth for CCTV

Many warehouses forget that CCTV doesn’t just need WiFi — it needs internet bandwidth for remote monitoring and cloud backup. A 20-camera HD setup needs 60–80 Mbps of upload bandwidth. If your internet link is 50 Mbps down/10 Mbps up, your cameras will drop frames constantly.

5. Plan for Forklift and Mobile Device Roaming

Forklifts and handheld scanners move throughout the warehouse. Your WiFi must support fast roaming — seamless handoff between APs without dropping connection. Industrial APs with 802.11r fast roaming and central controller management handle this. Consumer routers do not.

6. Test All AP Positions Before Permanent Mounting

Before drilling and cabling, test AP signal coverage from temporary positions. Walk the entire floor with a scanner or device to verify coverage at every pick location, dock door, and mezzanine. Fix gaps before mounting — not after.

7. Get a Dedicated Leased Line, Not Shared Broadband

If your warehouse is running on shared broadband, your entire operation depends on bandwidth that 100 other users in your building or street are sharing. One ISP maintenance window and your WMS goes down. A dedicated leased line gives your warehouse its own guaranteed bandwidth with an uptime SLA.

8. Plan a Backup Internet Link

A single internet connection is a single point of failure. For logistics operations, downtime means delayed shipments, missing deliveries, and customer penalties. A backup link with automatic failover (not manual) ensures operations continue even when the primary ISP fails.

9. Verify WMS / ERP Traffic Priority

Configure QoS so your WMS, ERP, and scanner traffic always gets bandwidth priority over general internet usage. Without QoS, a few employees streaming YouTube can starve out your picking systems during peak shift hours.

10. Account for Dead Zones in Docking Areas

Dock doors are a common WiFi blind spot — they’re at the edge of the building, furthest from the router, often with metal dock plates and high-bay lighting causing interference. Ensure your survey covers dock areas specifically, and add outdoor-rated APs for drive-in docks if needed.

11. Document Every AP Location and VLAN Configuration

After deployment, document exactly where every AP is mounted, what VLAN it’s on, and what channel it uses. When an AP fails (they do, eventually), your IT team or BTNL engineer needs to replace it quickly without rebuilding the network from scratch.

12. Get a Post-Deployment Validation Walk

After deployment, walk every aisle and dock with your scanner. Test connection continuity at every pick zone. Run a WMS transaction at each pick location to verify response times. This is your acceptance test — don’t sign off without it.
