“The WiFi is slow” is one of the most common complaints we hear from growing Perth businesses - and it's almost never actually about internet speed. It's a wireless design problem: one router trying to cover a space and device count it was never built for. Here's what proper business Wi-Fi design actually involves, and why it matters more as a team grows.

Why the WiFi in the corner isn't working anymore
Most small offices start with a single router - often the one supplied by the ISP - plugged in near the front desk or server cupboard. It works fine for five people. By the time a business has grown to fifteen or twenty staff, each carrying a laptop and a phone, plus printers, security cameras, and a POS system all competing for the same wireless channel, that single device is badly overloaded, and coverage rarely reaches the back of the office anyway.
The fix isn't a more expensive router - it's a properly designed wireless network with multiple access points, planned coverage, and traffic separated by purpose.
What proper Wi-Fi design actually covers
Coverage, not just one strong signal
A single access point, however powerful, has a coverage radius and a device capacity ceiling. Proper design places multiple access points so every part of the office gets a strong signal, with enough overlap that a laptop moving between meeting rooms roams seamlessly rather than dropping and reconnecting.
Capacity planning
Coverage on its own isn't enough - a single access point can serve a strong signal to fifty devices and still perform badly if it can't handle that many connections at once. Design has to account for device density: how many laptops, phones, and IoT devices are actually going to be connected in each area, not just how big the floor plan is.
Network segmentation
A well-designed business Wi-Fi setup separates traffic into distinct networks (VLANs) - typically a corporate network for staff devices, a guest network fully isolated from business systems, and often a separate network for IoT devices like printers, cameras, and smart displays that don't need access to the rest of the network and shouldn't have it.
Centralised management
Business-grade access points (Ubiquiti, Meraki, Aruba, and similar) are managed from a single cloud dashboard rather than logging into each device individually. That means faster troubleshooting, consistent policy across every access point, and visibility into what's actually happening on the network - which devices are connected, where congestion is occurring, and whether an access point has gone offline.
Wi-Fi 6, 6E, and 7 - what's actually worth paying for
Wi-Fi standards get marketed heavily on raw speed, which is rarely the actual bottleneck in an office. What matters more for a busy workplace is how well a standard handles many devices connected at once:
- Wi-Fi 6 - a genuine improvement for busy offices; handles many simultaneous devices far better than Wi-Fi 5 and is the sensible baseline for new hardware today
- Wi-Fi 6E - adds the 6GHz band, giving more clean spectrum in congested buildings or shared office spaces where 5GHz is crowded by neighbouring tenants
- Wi-Fi 7 - available but mostly future-proofing for now; the practical benefit for a typical SMB office is limited compared to the cost premium
Common interference sources in Perth offices
Site surveys regularly turn up interference sources businesses hadn't considered: metal shelving and racking in warehouses, tinted or Low-E glass in modern CBD office fitouts (which blocks signal more than standard glass), neighbouring tenants' networks in shared buildings, and microwave ovens or older cordless phones near the 2.4GHz band. A proper survey accounts for the building, not just a floor plan on paper.
What does a business Wi-Fi setup cost?
- Access points - $150-$400 per unit depending on capability, typically one per 150-200sqm of open office space
- Site survey and design - $1,000-$3,000 for a proper survey and coverage plan on anything larger than a small single office
- Cloud management licensing - $50-$150 per access point per year, where the platform requires it
- Cabling - most access points need a wired PoE (Power over Ethernet) connection back to a switch; existing cabling infrastructure affects installation cost significantly
Frequently Asked Questions
Why isn't a normal router good enough for an office?
Consumer routers are built for a handful of devices in a house, not dozens of laptops, phones, and IoT devices competing for airtime in an open-plan office. They lack centralised management, struggle with fast roaming between access points, and typically can't segment traffic into separate corporate, guest, and device VLANs the way business-grade access points can.
How many access points does my office need?
It depends on the floor plan, building materials, and device density - not just square metreage. A rough starting point is one access point per 150-200sqm of open office space, but a proper site survey accounting for walls, device count, and dead zones is the only reliable way to size it correctly before installing anything.
Is Wi-Fi 6 worth it for a small business?
Yes, if you're buying new hardware anyway - Wi-Fi 6 (and 6E) handle many connected devices far better than older standards, which matters more than raw speed in a busy office. Wi-Fi 7 is available but mostly overkill for typical SMB use today; Wi-Fi 6/6E covers the practical need at a lower cost.
What does a business Wi-Fi setup cost?
Business-grade access points run roughly $150-$400 each, plus a one-off site survey and design if the space is larger than a single small office - in an illustrative example, may $1,000-$3,000 depending on size. Cloud management licensing, where required, is usually $50-$150 per access point per year.
