Wi-Fi アクセスポイント数計算機.
カバー範囲、スループット、端末数から必要な Wi-Fi アクセスポイント数を見積もり、PoE とスイッチポートの目安も示します。
Realistic shared airtime throughput, far below the marketing PHY rate.
- For coverage
- 10 1,500 m² ÷ 150 m² (Office with partitions and meeting rooms)
- For throughput
- 2
- For device count
- 9
- Wi-Fi devices
- 300
- Peak Wi-Fi traffic
- 720 Mbps
- Switch ports and PoE
- 10 ports · 802.3at PoE (class 4)
- 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.

英語の技術説明
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.
