Warehouse Wi-Fi in Ajax, and why ceiling mounts fail
This is the one that gets designed wrong most often, and the mistake is always the same. Access points get mounted to the ceiling of a 40-foot building, pointing down, and the coverage map looks perfect until the racking is full.

What Ajax is, in the parts that affect this work
The Ajax employment lands run to big-box logistics. Buildings in the GTA East Industrial Park off Salem Road North are specified with 40-foot clear height and truck-level doors, which is a warehouse built for vertical racking rather than for people at desks.
This page is about what that means for business wi-fi specifically. For how the work itself runs, what is included and what it costs to scope, the Business Wi-Fi & Mesh page is the one to read.
A standard access point points down and expects to be ten feet up
The access points sold for offices have omnidirectional antennas designed to radiate outward and slightly down from a ceiling roughly three metres above the users. Their whole radiation pattern assumes that geometry.
Put the same unit at twelve metres and most of its signal is spent on air. What reaches the floor is weak, and it arrives from a long way off, which means a handheld sees several distant access points at similar weak strength and cannot decide between them. The device does not fail: it hesitates, roams badly, and drops scans intermittently, which is far harder to diagnose than a dead spot.
Then the racking gets filled. Loaded racking is a wall of absorbent material with metal in it, and coverage that came from overhead now cannot get into the aisle at all. The system worked at handover and stopped working when the business started using the building.
What actually works in a high-clear building
Directional antennas aimed along the aisles, mounted at a height where the signal travels down the aisle rather than into the top of the racking. The aisle becomes a corridor the signal runs along, and a handheld in that aisle has one strong access point rather than four weak ones.
Alongside that: transmit power turned down so cells stay small and handoffs are decisive, the oldest slow data rates switched off so a device cannot cling to a distant access point, and the 2.4GHz radio used sparingly because it travels further than you want in a building this size and interferes with itself.
None of this is exotic and none of it is expensive. It is a design decision made at the start, and it is the difference between a warehouse wireless network that works and one that gets three rounds of extra hardware thrown at it.
Survey the building you are going to have
A survey of an empty warehouse is close to worthless, because the empty building is not the building you operate. Where racking is going in, we design for the loaded state from the rack layout, then verify with a real survey once it is stocked and adjust.
We would rather build that second visit into the quote than hand over a design that verified beautifully on an empty slab. If an installer offers you a warehouse Wi-Fi design with no post-stocking verification, that is the question to ask them.
Getting to you in Ajax
Ajax sits inside our regional travel band. That is one flat charge per site visit, not per hour and not per technician, and it is on the quote as its own line before you agree to anything. If a job needs three visits you will see three of them, which is also why we would rather scope it properly once.
We are a service-area business based in Oshawa with no storefront, so every job happens at your premises. If your site sits at the edge of what we cover, we would rather say so on the phone than find out on the day.

Before you call
We already have access points and it still drops. More of them?
Usually not, and adding them often makes it worse by increasing the number of weak signals a handheld has to choose between. The first things we check are mounting height, antenna type, transmit power and whether legacy data rates are enabled. On most sites we can improve it substantially before buying anything, and we would rather do that first so you can see what the remaining gap actually is.
Does the handheld vendor's recommendation matter?
Yes, and it is worth getting in writing. Some warehouse handhelds have specific roaming behaviour and documented minimum signal requirements, and designing to a generic office standard when the vendor has published a number is how you end up in a support argument with them. Send us their deployment guide and we will design to it.
How does a wireless bridge fit in?
It does not, and the two get confused constantly. Wi-Fi covers devices inside a building. A wireless bridge is a point-to-point link that carries your network between two buildings, usually where trenching is not practical. If you have a second building on the site, that is a bridge question and a separate piece of work.
