- Rules of thumb only. Walls, ceilings, interference and antenna types change coverage a lot; a predictive or on-site survey is the reliable way to place access points.
- In dense areas, prefer more APs at lower transmit power on 20/40 MHz channels in 5 GHz (and 6 GHz where allowed), rather than fewer APs at full power.
- Regulatory channels and power limits differ by country.

Rules of thumb only; a predictive or on-site survey is needed for a final design. Regulatory channels and power vary by country. Everything is calculated in your browser; nothing is sent or probed on the network.
Coverage = area ÷ typical cell area for the environment. Throughput = active devices × rate ÷ realistic AP throughput. Device count = devices ÷ maximum devices per AP. Growth headroom applies to the last two.
1,500 m² of partitioned office with 150 people and 2 devices each needs about 10 Wi-Fi 6 access points, limited by coverage.
