Estimate per-AP coverage after accounting for wall attenuation.
How this calculator works
Reliable Wi-Fi is constrained by both radio coverage and capacity. The planner compares physical area, walls, floor count, room count and user density, then uses the largest requirement and adds outdoor coverage when needed.
Check floor, room and simultaneous-user density constraints.
Size PoE switching, router class and internet capacity for the resulting network.
Worked example
A practical planning scenario
A 650 m² concrete building with 35 rooms and 100 simultaneous users needs more than a simple area-based division would suggest. User density and partitioning may drive the AP count above the coverage-only estimate.
Frequently asked questions
Can one strong router cover a duplex?+
Sometimes parts of it, but concrete floors and walls often create weak zones. Wired access points usually provide more reliable coverage and capacity.
Does Starlink include whole-building Wi-Fi?+
Starlink supplies internet access. Large or partitioned properties still need a distribution network with access points, switching and cabling.
Why recommend wired access points?+
A wired backbone preserves capacity and stability better than repeating the signal wirelessly across several hops.
