Secure Wireless

“The Wi-Fi is slow” is rarely about the Wi-Fi

When wireless underperforms, the reflex is to add access points. Sometimes that helps. More often it makes things worse — more radios competing for the same spectrum, clients clinging to a distant AP because it is still just barely audible, and interference the original design never accounted for.

The underlying issue is usually that the network was designed for coverage when the problem is capacity. A warehouse with a handful of scanners and a lecture hall with three hundred laptops can have identical floor plans and need completely different designs. Coverage asks “is there signal here?” Capacity asks “how many devices, doing what, at once, in this room?” The second question is the one that determines whether people complain.

And there is a security dimension that rarely gets designed at all: once a device associates, what is it allowed to reach? On a lot of networks the honest answer is “most things,” because wireless was treated as a connectivity project rather than an access-control one.

What this covers

Survey and RF design

Predictive modelling against real floor plans and construction materials, then validation on site — because drywall, concrete, metal racking, elevator shafts and foil-backed insulation all behave differently from what a model assumes. We design channel plans and power levels to minimize co-channel interference rather than maximizing raw signal, which is the usual cause of a network that looks strong on a heat map and performs badly in practice.

Capacity and density planning

Designing for the busiest realistic moment in each space, not the average. Device counts, application mix, and what happens when everyone arrives at once. Areas with genuine high density — auditoriums, classrooms, clinical floors, conference space — get different treatment from corridors and storage.

Authentication and identity

Certificate or credential-based authentication with 802.1X where it fits, so access follows identity rather than a shared passphrase that half the building knows and nobody can rotate. Onboarding that distinguishes a managed corporate device from a personal phone from a contractor’s laptop — and treats each accordingly.

Segmentation and guest access

Putting devices where they belong once they connect. Corporate, personal, guest, and the growing category of things that are neither — badge readers, HVAC controllers, cameras, medical and industrial equipment — each on the right side of an enforced boundary. Guest access that reaches the internet and nothing else, which is harder than it sounds when guest traffic shares infrastructure.

Standards and lifecycle

WPA3 where the client estate supports it and a defensible plan where it does not, 6 GHz adoption when the devices in the building can actually use it, and firmware lifecycle handled deliberately rather than whenever something breaks. Wireless standards move faster than most refresh cycles; the design should account for the devices you have, not the ones in the datasheet.

How we engage

Vendor-neutral by design

We design and deploy across the major wireless platforms and will work with what you already own. The right choice depends on the environment, the client devices in the building, what your team can operate confidently, and what is already on the balance sheet — not on which manufacturer we happen to be certified with. See the vendors we work with.

Frequently the honest recommendation is that the hardware is fine and the design is the problem. A re-survey and a channel plan costs considerably less than a forklift replacement, and we would rather tell you that than sell you access points.

Who this is for

• Buildings where wireless works in some places and not others, and adding access points has stopped helping.
• High-density environments — education, healthcare, conference and event space — where average performance is irrelevant and the peak is what matters.
• Warehouses, manufacturing floors and other physically demanding spaces where racking, machinery and constant layout changes defeat a standard design.
• Organizations still running a shared passphrase, or with a guest network that can see more of the estate than anyone intended.
• Teams facing a compliance requirement that expects device-level access control on the wireless network.
