Planner · Home network
Will one router cover your home — or do you need a second access point?
Enter the floor size, wall type and where the router lives. This planner turns that into an effective radius per band, a coverage score, the weak zones on the plan, and a realistic access-point count — all in your browser.

How the numbers are worked out
Every figure below is arithmetic you can check by hand. Nothing is fetched from a server. Preset figures are typical values, not one vendor's spec sheet.
Reference radius per band & class
Free-space reference: 2.4 GHz ≈ 30 m, 5 GHz ≈ 18 m, 6 GHz ≈ 13 m. Scaled by router class — basic 0.78×, mid 1.0×, Wi-Fi 6 1.15×, Wi-Fi 6E mesh 1.28×.
Penalties & floor loss
Construction × placement × 0.55 per extra floor. Open 1.0, stud 0.85, brick 0.65, concrete 0.45. Centre 1.0, mid-wall 0.82, corner 0.62, another floor 0.55.
Coverage score
Effective radius r = ref × penalties. Coverage area = π·r². Score = covered ÷ total (width×depth×floors), capped at 100% and floored at 5% so a weak plan is honestly weak. Weak area = total − covered.
Access points
Suggested APs = ceil(total area ÷ (coverage per AP × 0.75 overlap)), minimum 1. Band advice: 5/6 GHz for throughput near the AP, 2.4 GHz for reach at the edges.
What this is not: a floor-plan estimate, not an RF survey; real coverage depends on furnishings, neighbouring networks and antenna patterns.
Questions
Does one router really cover my whole home?
It depends on area, walls and where the router sits. About 60 to 80 square metres of open or stud-wall space on one floor is usually fine with a centred mid-range router; brick or concrete and a corner placement shrink that quickly. The planner converts your dimensions into an effective radius and a coverage score so you can see the weak zones.
Which band should I use — 2.4, 5 or 6 GHz?
2.4 GHz reaches furthest and penetrates walls best but is slower and more crowded. 5 GHz and 6 GHz are faster close to the access point and less congested, but their range is shorter — around 18 m and 13 m free-space reference before walls and floors are applied.
How many access points do I need?
Total floor area is divided by the coverage of one access point times a 0.75 overlap factor, then rounded up to at least one. The result is a starting point; real placement matters more than the count — centre the first AP and add others at the edges of its ring.
Is this an RF survey?
No. It is a geometry estimate from simple radius and penalty factors, not a measured survey. Furnishings, neighbouring networks, antenna patterns, device orientation and channel choice all change real coverage. Use it to plan before you buy, then test with a walk-through.
