Why warehouse WiFi is harder than it looks
An empty warehouse floor seems ideal for WiFi: no walls, no furniture. Then the racking goes in. Metal shelving loaded with stock behaves like a row of walls, aisles become narrow corridors for signal, and the steel shell stops most outside signal getting in, including mobile coverage. A floor that tested well on the first day can have dead spots once it fills up.
Height is the other factor. Access points mounted high can cover a lot of floor in open areas, but the signal has to come back down past lights, beams and the tops of racks. Most warehouses also have an office block or mezzanine where the laptop work happens, and that area usually needs its own coverage plan.
How many access points a warehouse needs: coverage vs capacity
Two calculations, and the larger answer wins. These are planning starting points we confirm on-site; the event network planner runs the same sums for your numbers.
| Warehouse | Coverage estimate | Capacity estimate | Usually decides |
|---|---|---|---|
| 1,800 m² open floor, 20 staff | About 2 (1,800 ÷ 900) | 30–40 devices: 1 access point | Coverage |
| 5,000 m² floor plus upstairs offices, 50+ people | About 6 (5,000 ÷ 900, rounded up) | 75–100+ devices: 2 access points | Coverage |
| 3,000 m² with full-height racking | 4 or more, as racking adds points beyond the open-floor figure | Depends on scanners and staff devices | Coverage, then layout |
| 1,000 m² floor used for a 200-person event | About 1–2 | Around 200 devices: 4 access points | Capacity |
Devices: 1.5–2 per working person, about 1 per attendee at public events. Capacity: about 50 devices per access point.

Mesh or cabled access points in a warehouse
Both work in warehouses, and the right answer depends on how long you're there and how the space is used. Our mesh vs wired access points guide goes deeper.
Mesh with wireless backhaul
Nodes link to each other by radio, so each position only needs power. It avoids long cable runs across a big floor and suits project sites, fit-outs and leases of weeks or months.
Cabled access points
Each access point has a network cable back to a PoE switch. More capacity per point and better in dense racking, but runs take longer and need routes along walls or ceilings.
Hybrid
Cabled access points where cable is easy, such as the office block, with mesh nodes across the floor where running cable would be slow.
Fixed cabling
Where data cabling has to connect to the telecommunications network, it's done with our partnered ACMA-registered cablers.
Scanners, forklifts and roaming across the warehouse floor
Handheld scanners and tablets on forklifts move constantly, so they need to hand over from one access point to the next without dropping their session. That means overlap between coverage areas along the aisles, not just a strong signal near the dock. We test along the routes people actually walk and drive, not only at a few points in the middle.
Scanners and warehouse software sometimes rely on 2.4 GHz WiFi, while laptops in the office do better on 5 GHz or 6 GHz. Tell us the make and model of any handhelds before we plan, so the network supports them from the first shift. For the technical detail, see our warehouse WiFi coverage guide.
Warehouse WiFi and CCTV in one visit
Most warehouse projects need cameras as well: entries, the dock, high-value stock and the office door. Installing security cameras with the network saves a second trip, and one PoE switch can power cameras and access points from the same rack. Cameras get their own part of the network, separate from staff and scanners, with recording equipment on-site and viewing options agreed in your plan.
From floor plan to tested warehouse network
Floor plan and walk-through
We mark the floor, racking, dock, office block and where people will work, and note ceiling height and available power.
Connection
We check whether there's a usable service, and what can be activated at the address if not. Upload is planned first when large files or video calls are part of the work.
Placement plan
Access point or mesh node positions, separate networks for staff, scanners, guests and cameras, and the switch ports each one needs.
Install and test
Every position is tested across the floor and in the offices, including along the aisles where scanners roam.
Return after move-in
Once people and stock are in, we come back to adjust placement if the plan includes it, because a full warehouse behaves differently from an empty one.
Questions people ask
How many WiFi access points does a warehouse need?
A warehouse usually needs one access point per roughly 900 m² of open floor as a starting point, with more for full-height racking, office blocks and mezzanines, then a capacity check at about 50 devices per access point. In most warehouses coverage decides the number, so testing at the actual positions matters more than headcount.
Does WiFi work through warehouse racking?
WiFi does travel along warehouse racking aisles, but loaded metal shelving blocks and reflects signal, so coverage in one aisle says little about the next. Access points placed to look down the aisles, with overlap between them, give the most even result. We test along the aisles after install, and again after stock arrives if that's in the plan.
Is mesh WiFi good enough for a large warehouse?
Mesh WiFi can cover a large warehouse well when the nodes are tri-band and close enough to keep a strong wireless link between them. It suits temporary and project sites because it avoids long cable runs. For very dense racking or many heavy users, cabled access points add capacity. Our 5,000 m² case used six mesh nodes.
Can you put WiFi in the upstairs offices of a warehouse too?
Yes. Upstairs and mezzanine offices are part of a warehouse WiFi plan, not an afterthought. Floors and steel structure block signal between levels, so the office area usually gets its own access point or mesh node on the same network, and people keep their connection as they move between the office and the floor.
Can security cameras and WiFi be installed together in a warehouse?
Security cameras and WiFi can be installed in one visit in a warehouse. The PoE switch powers both, cameras run on their own separate network, and recording equipment stays on-site. How you view footage is agreed in your plan. Doing both together usually means fewer cable runs and one point of contact.
How long does it take to get internet into an empty warehouse?
A new service for an empty warehouse can take from a couple of business days to several weeks, depending on the address and existing equipment. A 4G/5G router can cover the gap for a small team, and the WiFi itself is a much shorter job once there's a connection.
