Wi-Fi 6 access points still need a wired backbone to actually perform. We walk through why the cabling you can't see is usually the reason "great Wi-Fi" feels slow eighteen months after handover.
Every Access Point Is Only as Fast as Its Cable
A Wi-Fi 6 access point can theoretically push over a gigabit, but if it's connected back to the switch over an old Cat5e run, that's the actual ceiling — regardless of how new or expensive the access point is. The wireless spec on the box is a best-case number the cabling behind it has to support.
Density Is the Real Bottleneck, Not Speed
Most "slow Wi-Fi" complaints in offices aren't a bandwidth problem — they're a density problem. Too many devices on too few access points, spaced too far apart, because the original design under-cabled the floor to save cost. Structured cabling done right means enough access point locations to keep device-per-AP counts reasonable, not just one AP per floor pushed to its limit.
Power over Ethernet Changes the Calculation Too
Access points, IP phones, PA speakers, and PTZ cameras increasingly run on PoE — power and data over the same cable. That means your cabling plan isn't just a networking decision anymore; it's an electrical one too, and it needs switches with enough PoE budget to actually power everything connected to them.
Common Mistakes We See
- Undersized backbone: Cat5e runs installed years ago, never upgraded as device counts grew
- No redundancy: A single uplink cable that takes down an entire floor if it fails
- Poor labeling: Patch panels with no documentation, turning every fault into a treasure hunt
It costs less to run an extra cable during fit-out than to open a finished ceiling eighteen months later because Wi-Fi "just isn't working."
Sizing It Right the First Time
We cable for the floor's eventual device count, not its day-one count — access points, cameras, door controllers, and PA speakers all compete for the same backbone. Getting this right at fit-out stage is one of the cheapest insurance policies in the entire project.
