Three generations of wireless, a decade of progress, and a simple question for every home and office: which one do you actually need? Here's the honest engineering view — not the box on the shelf.
One leap at a time
Each generation kept what worked and solved the problem the last one couldn't — first raw speed, then crowded airspace, now latency and spectrum.
The size of the leap
Maximum theoretical link rate, drawn to scale. The gaps are real — but read the note underneath before you spend on them.
Which airspace each one can use
More bands means more room to breathe. The clean, wide 6 GHz band is where Wi-Fi 6E and 7 pull ahead in busy buildings.

The badge is the ceiling, not the floor
The number on the box is the theoretical maximum under perfect lab conditions. In a real villa or office, your usable speed is decided by access-point placement, channel planning, the wired backhaul feeding each AP, interference from neighbours, and the slowest device on your network. A well-designed Wi-Fi 6 network will comfortably beat a badly-installed Wi-Fi 7 one.
Wi-Fi 7's headline numbers also assume the infrastructure behind it can deliver them. A 46 Gbps radio fed by a single gigabit cable is throttled at the wall. To realise it you need a Cat 6A backbone and 2.5/10 GbE switching — the structured cabling and network design that is QSN's core work, not an afterthought.
You're keeping existing gear alive on a tight budget and the workload is light — browsing, calls, SD/HD video for a few devices.
It's most homes and offices today. Many devices, smart-home and CCTV load, 4K streaming. The best value-for-performance default in 2026.
Large villa or estate, heavy concurrent 4K/8K, VR, low-latency needs — and you're building the Cat 6A / 10 GbE backbone to back it.
Not sure which your space needs?
That's the right question to ask before buying. QSN runs a heatmap survey of your property and designs the network around how you actually use it — then supplies, installs and manages it end to end.
