IT for warehouses and logistics operations in the UAE.

Why warehouse IT is an operations issue

In a warehouse, IT is part of the physical flow of goods. If the warehouse management system (WMS) is unreachable, the scanners lose their connection or the site internet link drops, pickers stand still and trucks wait at the dock. The cost of a fault is measured in delayed dispatches, not in a ticket queue. That is why warehouse IT should be planned around the way the operation works: its shifts, its peaks and the specific systems that stop dispatch when they fail. For the service view, see the logistics IT services page.

1. Wi-Fi coverage in racking environments

Most warehouse Wi-Fi problems come from a network designed for an office and then stretched over a warehouse. Racking, stock and metal reflect and absorb signal, and the coverage you measured in an empty building changes once the racks are full.

• Survey with the racking and typical stock in place, or re-survey after the layout changes.
• Design for the aisles, docks and yard where scanners are used, not for the open floor as a whole.
• Choose access points and antennas suited to the environment, and mount them at heights that clear the racking.
• Plan for roaming. Handheld scanners moving between access points need a configuration that hands over cleanly without dropping sessions.
• Allow for capacity as well as coverage. Many scanners, printers and vehicle-mounted terminals share the same airspace.

The Wi-Fi and network solutions page and the guide to Wi-Fi design for multi-site businesses cover the wider approach.

2. Scanners, handhelds and label printers

Handheld scanners, vehicle terminals and label printers are the working tools of the floor. They need the same care as servers, although they often get less.

• Manage handhelds centrally, so settings, applications and updates are applied consistently rather than device by device.
• Keep a stock of spare scanners, batteries and charging cradles so a failed unit is a swap, not a delay.
• Standardise on a small number of models, which makes spares and support simpler.
• Document how each printer is connected and which system sends it labels, so a replacement can be set up quickly.
• Track the age of the fleet. Old devices running unsupported software are both a reliability and a security risk. See mobile device management.

3. WMS and ERP uptime

The WMS and the ERP or accounting system behind it are the systems that stop dispatch. Your software vendor supports the application, but the infrastructure underneath is yours: servers or cloud hosting, the database, the network, the internet link and the backups.

• List the systems that stop dispatch if they fail, and rank them. Spend attention on the top of that list first.
• Monitor the servers, links and services involved, so faults are seen before the floor reports them.
• Know who to call for each layer: application vendor, hosting provider, network and internet provider, and your own IT support.
• Write a short manual-process fallback, for example how to keep picking and dispatching on paper for a short outage, and how to key the data in afterwards.

The cost of IT downtime guide and the downtime cost calculator can help to set priorities.

4. Network segmentation

A warehouse network typically carries very different kinds of traffic: office computers, scanners, printers, cameras, building systems and sometimes visiting drivers and contractors. Putting all of it on one flat network means a problem in one place can reach everything.

Segmentation separates these groups into their own networks, with a firewall deciding what can talk to what. In practice that means separate networks for office staff, for scanners and warehouse systems, for CCTV and building systems, and for guests. It limits the spread of malware, makes faults easier to trace and protects the systems that matter most. A managed firewall at each site, configured the same way, also makes multi-site operations easier to run. See the firewall solutions page for the options.

5. Power and UPS

A short power interruption can freeze a server, drop a switch and take the whole floor offline, long after the lights come back. Equipment that carries dispatch should have protection against power loss.

• Put the server, core switches and internet equipment on a UPS sized for the load, with some time to shut down cleanly or ride through a short outage.
• Consider UPS cover for the access points and switches that serve the scanner areas, not just the server room.
• Check batteries and test the UPS periodically. Batteries age, and a UPS that has never been tested is an assumption.
• Keep cooling in mind. Equipment in a hot store room or a cabinet without airflow fails early.

The server room and UPS page and the server room and UPS checklist go into the detail.

6. CCTV and site security

Warehouses use CCTV for safety, stock control and security. Cameras generate a lot of video, so the network, storage and retention need planning. Keep the camera network separate from the operational network, decide where footage is stored and for how long, and protect access to the recorder. See the cabling and CCTV page and the CCTV planning guide.

7. Failover internet

If the warehouse depends on a cloud WMS, a single internet link is a single point of failure. A second link from a different provider, ideally over a different physical route, with automatic failover on the firewall, keeps the site working when one link fails. Test the failover rather than assuming it works. For sites that use a hosted system, also check what the floor can still do if the link is lost completely, which is where the manual fallback in section 3 comes in.

8. Change windows around shipping peaks

Updates, firmware changes, new access points and network work should not happen in the middle of a dispatch wave. Agree change windows with operations: quiet periods between shifts, or planned slow days, and avoid the run-up to known peaks such as seasonal sales periods or month end. Every change should have a clear plan, a person responsible, and a way back if it does not work. Telling the floor supervisors in advance avoids surprises. A short change calendar shared between IT and operations is usually enough.

9. Backup of operational data

Operational data is stock levels, orders, shipment records, customer details and invoices. Losing it, or having to rebuild it from paper, is more disruptive than most hardware failures. Back up the WMS database and the ERP, not just the file server, keep at least one copy away from the site, and test a restore. Ransomware that reaches the backups defeats the point, so keep one copy that cannot be changed by the production network. The restore test checklist and the backup and disaster recovery page show how.

Where to start

List the systems that stop dispatch, check how each is monitored and backed up, and walk the floor to see where scanners lose signal. If you would like a structured outside view, the free IT health check is a practical first step.
